Last updated: September 2026. This is a documentary audit of the public catalogue rather than a field test. Every price, rate, rule and limitation was read from Yesim’s own product pages, help centre and terms, with the main collection on 14 September 2026 and price checks on 20 September. It covers 1,297 plan options, 170 Pay & Fly destination rates, 444 coverage entries, 58 usage rules and 44 commercial conditions. Prices are native quotations in USD or EUR with no conversion applied. No speed or support testing was carried out.
Most travel eSIM reviews compare one product against another. This Yesim Review 2026 needs a different approach, because Yesim sells four genuinely different things and the choice between them moves the price more than the choice between Yesim and a competitor would.
You can buy a fixed allowance, an unlimited plan, a pay-as-you-go wallet called Pay & Fly, or a pack of 24-hour day passes valid across a year. Each suits a different kind of trip, each has conditions the others do not, and the published comparisons disagree with each other and occasionally with Yesim itself on the basic numbers. So we read the catalogue: 1,297 plan options and 170 per-country Pay & Fly rates.
How this review is built, and what it is not: I’m based in Belgium and compare eSIM providers full-time. This is a documentary audit rather than a field test, so there are no speed measurements, coverage results or support response times from my own use, and none should be inferred. For this Yesim Review 2026, every figure comes from Yesim’s own product pages, help centre articles, refund policy and terms of service, collected on 14 September 2026 with price checks on 20 September, and the source recorded for each. Where Yesim’s own documents contradict each other, and they do in four separate places, this review reports every version rather than choosing the most attractive one. Related audits: Roamless Review 2026, which uses a similar wallet model, and GigSky Review 2026.
💸 The Pay & Fly finding: the same wallet buys five times more data in the United States than in Egypt. Across the 170 destinations published in September 2026, the cheapest rates are $1.80 per gigabyte in the United States, Germany, France and Spain. Greece and Albania sit at $2.40, Turkey at $3.60, and a large middle group including Thailand, Italy, the United Kingdom, Japan, Mexico and Brazil at $4.80. Above that, the UAE is $5.40, Russia and Saudi Arabia $6.00, China $6.60, and Egypt $9.00. That is a fivefold spread inside one product. One published review reports rates reaching $144 per gigabyte in Bhutan and as low as $1.10 in Ukraine, both outside our sample, so the true range is wider still. That fivefold spread is one of the clearest findings in this Yesim Review 2026. Pay & Fly is not cheap or expensive as a product. It is cheap or expensive depending on where you land.

The Four Modes, and When Each One Wins
| Mode | What you buy | Best for | The condition that decides it |
|---|---|---|---|
| Fixed data | A gigabyte allowance with a validity window | Trips with predictable consumption | ⚠️ Unused gigabytes expire, and a top-up replaces rather than adds |
| Unlimited | Uncapped data for a fixed number of days | Heavy use across consecutive days | ⚠️ No published high-speed allowance and no published reduced speed |
| Pay & Fly | A wallet debited per gigabyte at local rates | Occasional trips with light use | ⚠️ Rates vary fivefold by country · €15 minimum to activate |
| Unlim Day Pass | 24-hour sessions usable within 365 days | Travel days scattered across a year | ⚠️ Only beats a 30-day unlimited at the 80-day tier |
🧭 The quickest way to choose. The core decision in this Yesim Review 2026 is how your travel days fall, not simply how much data you need. Consecutive days with heavy use points to unlimited. Consecutive days with predictable use points to fixed data, which is the only mode guaranteeing a known allowance at full speed. A handful of light days points to Pay & Fly, provided you check your country’s rate first. And days spread across a year, the business traveller pattern, is the only case where the Day Pass makes sense. Getting this wrong costs more than picking a different provider would.
Video: What an eSIM Is and How It Works Before You Buy
If you are using this Yesim Review 2026 while still comparing eSIM with a physical SIM, this short walkthrough gives the basic setup context before the Yesim-specific details below. Understanding where the eSIM profile lives, when mobile data switches over and what happens after installation makes the plan rules much easier to follow.
After watching, you can compare the practical differences in our eSIM vs physical SIM guide or check whether your device appears in the eSIM-compatible phones list. The rest of this review focuses specifically on Yesim pricing, activation and usage rules.
Pay & Fly: The Rate Table That Decides Everything
In this Yesim Review 2026, Pay & Fly is the mode most people are most likely to misread, because the headline suggests a simple pay-as-you-go product and the pricing is anything but uniform. Here are the published rates for the destinations travellers ask about most.
| Destination | USD / GB | EUR / GB | 5GB would cost | Networks listed |
|---|---|---|---|---|
| 🇺🇸 United States | $1.80 | €1.50 | $9.00 | 2 |
| 🇩🇪 Germany · 🇫🇷 France · 🇪🇸 Spain | $1.80 | €1.50 | $9.00 | 2 each |
| 🇬🇷 Greece · 🇦🇱 Albania | $2.40 | €2.00 | $12.00 | 2 and 1 |
| 🇹🇷 Turkey | $3.60 | €3.00 | $18.00 | 2 |
| 🇬🇪 Georgia | $4.08 | €3.40 | $20.40 | 2 |
| 🇹🇭 Thailand · 🇮🇹 Italy · 🇬🇧 UK · 🇯🇵 Japan | $4.80 | €4.00 | $24.00 | 1 to 4 |
| 🇲🇽 Mexico · 🇧🇷 Brazil · 🇲🇦 Morocco · 🇻🇳 Vietnam | $4.80 | €4.00 | $24.00 | 2 to 4 |
| 🇦🇪 United Arab Emirates | $5.40 | €4.50 | $27.00 | 1 |
| 🇷🇺 Russia · 🇸🇦 Saudi Arabia | $6.00 | €5.00 | $30.00 | 2 and 1 |
| 🇨🇳 China | $6.60 | €5.50 | $33.00 | 2 |
| ⚠️ 🇪🇬 Egypt | ⚠️ $9.00 | €7.50 | ⚠️ $45.00 | 2 |
Rates published on Yesim’s Pay & Fly modal on 14 September 2026, covering 170 destinations. The 5GB figures are arithmetic from the published rate, not quoted packages. Network counts are the entries Yesim lists per destination.
⚠️ Three conditions that turn Pay & Fly from clever into expensive. First, activation requires a balance of at least €15 according to Yesim’s help, updated in June 2026. One widely-read review states the balance starts from €29, which does not match. Second, the rate is charged on data sent and received, so background syncing, map tiles and app updates all draw down the wallet at the local rate. Third, and most important: at $4.80 a gigabyte, five gigabytes in Italy costs $24, while a fixed Europe plan of similar size costs considerably less. Pay & Fly wins on light use and loses on volume, which is the opposite of how most people instinctively read a pay-as-you-go product.
💰 And the wallet expiry question has three official answers. The Pay & Fly page says the balance does not expire. The top-up help article says Ycoins expire after six months without activity. The loyalty tiers page says cashback does not expire. A published review adds a fourth version by saying the balance stays valid for a full year. Those cannot all be true of the same wallet, and Yesim has not reconciled them publicly. We are not in a position to decide which governs, so we report all four. If you are loading a large balance for occasional trips, keeping the account active is the safest hedge, and loading only what you expect to spend is safer still.
Global Package Against Global Plus: $48 for Coverage You May Not Need
| Plan | Global Package 83 destinations | Global Plus 146 destinations | The Plus premium |
|---|---|---|---|
| 5GB / 30 days | — | $28.80 | Plus only |
| 10GB / 30 days | $34.80 | — | Package only |
| 10GB / 90 days | — | $46.80 | Plus only |
| 20GB / 90 days | $46.80 | — | Package only |
| 20GB / 180 days | — | $70.80 | Plus only |
| 40GB / 365 days | $82.80 | $130.80 | ⚠️ $48.00 more for the same data |
| 80GB / 365 days | $130.80 | — | Package only |
| Unlimited 7 days | $40.80 | $78.00 | ⚠️ $37.20 more for the same week |
| Unlimited 15 days | $54.00 | $118.80 | ⚠️ $64.80 more |
| Unlimited 30 days | $94.80 | — | Package only |
🌍 The premium is real and it buys exactly one thing: 63 more destinations. At 40GB over 365 days you pay $82.80 on Global Package and $130.80 on Global Plus, identical data over an identical period. On unlimited the gap widens: $40.80 against $78 for the same week, and $54 against $118.80 for the same fortnight. So this is not a value comparison, it is a coverage one. Open both destination lists, find your countries, and only pay the Plus premium if your route genuinely needs the wider footprint. For this Yesim Review 2026, that makes Global Plus a coverage decision rather than a data-value upgrade. Note also that the catalogue’s headline of 200-plus destinations is the brand total across every product, not what either global plan gives you, a distinction we found repeatedly in our MobiMatter audit.
Regional Plans: Asia Pacific Is Cheap, Africa Is Not
| Plan | Asia Pacific 16 destinations | Per GB | Africa 15 destinations | Per GB |
|---|---|---|---|---|
| 1GB / 30 days | — | — | €9.70 | €9.70 |
| 3GB / 30 days | — | — | ⚠️ €35.00 | ⚠️ €11.67 |
| 5GB / 30 days | €10.00 | €2.00 | €49.00 | €9.80 |
| 10GB / 30 days | €18.60 | €1.86 | €74.00 | €7.40 |
| 20GB / 30 days | €29.80 | €1.49 | — | — |
| 30GB / 30 days | €38.00 | €1.27 | — | — |
| Unlimited 1 day | €7.00 | — | €24.00 | — |
| Unlimited 7 days | €25.00 | — | — | — |
🌍 Africa’s 3GB plan costs more per gigabyte than its 1GB plan, and nine times what Asia Pacific charges. At €35 for 3GB that works out to €11.67 a gigabyte, against €9.70 for the 1GB plan and €1.27 for Asia Pacific’s 30GB. Wholesale roaming across African markets genuinely costs more and Yesim is not alone in this, but the internal ordering is worth flagging: buying three gigabytes costs more per gigabyte than buying one, which is unusual even in an expensive region. Asia Pacific at the other end is genuinely competitive, with 30GB for €38 and a single unlimited day for €7. This Yesim Review 2026 therefore treats regional pricing as a separate decision from the global plans.

Unlimited: What Yesim Does Not Publish
| Source | High-speed allowance | Reduced speed | Recovery |
|---|---|---|---|
| Yesim’s unlimited policy | ❌ Not published | ❌ Not published | Mentions daily or monthly cycle |
| Yesim’s August 2026 help article | Attributes fair use to network partners | Not specified | Not specified |
| Independent field test, July 2026 | 12GB over six days without throttling | Not reached | — |
| ⚠️ A published comparison | — | — | States a 24-hour reset |
🚨 Nobody can tell you Yesim’s unlimited limit, and this review will not invent one. That lack of a published figure is why this Yesim Review 2026 keeps the unlimited section tied to documented limits rather than guessed thresholds. The policy attributes fair use to network partners without specifying a high-speed allowance, and the general policy sets no gigabyte figure and no reduced speed. You can compare that wording with Yesim’s official unlimited-data help article. An independent reviewer who tested it in two countries reported using around 12GB over six days without hitting throttling, while stating plainly that Yesim does not clearly disclose how much high-speed data is included. One published comparison asserts that speeds reduce after a daily threshold and reset every 24 hours; the policy actually mentions recovery in a daily or monthly cycle and does not establish that every reduction ends after a day. Any review quoting 5GB a day, 512kbps or 1Mbps for Yesim is supplying a number the documentation does not contain.
📦 Which is why the fixed plans deserve a serious look. The same independent reviewer makes the point well: a 20GB fixed plan can cost roughly the same as a short unlimited plan while guaranteeing the full allowance at high speed. On Yesim specifically, the Asia Pacific 30GB at €38 or the Global Package 20GB over 90 days at $46.80 give you a known quantity, which an unlimited plan with an unpublished threshold cannot. Buy unlimited when your usage is genuinely unpredictable, and fixed data when you can estimate it, because on this provider the fixed plans are the only ones with a specification you can hold them to.
The Unlim Day Pass: Do the Arithmetic First
| Day Pass | Price | Per day | Against Global Package unlimited |
|---|---|---|---|
| 10 days | $58.80 | ⚠️ $5.88 | ⚠️ Worse than 7 days at $5.83 |
| 20 days | $82.80 | $4.14 | Worse than 30 days at $3.16 |
| 40 days | $130.80 | $3.27 | Still above the 30-day rate |
| 80 days | $238.80 | $2.99 | ✅ The only tier that beats $3.16 |
📅 The Day Pass is a scheduling product, not a discount. Within this Yesim Review 2026, it only undercuts the 30-day unlimited daily rate at the 80-day tier. At ten days it works out to $5.88 a day, which is more than the $5.83 a day of a seven-day Global Package unlimited and nearly double the $3.16 a day of the thirty-day version. It only becomes cheaper per day at the eighty-day tier, at $2.99. So buy it when your travel days are scattered across a year and a consecutive plan would waste most of its validity, not because it looks like bulk pricing. Three conditions matter: each day is a 24-hour session starting on connection, turning the profile on in a covered home country can consume a day, and the published coverage count differs between sources, with a February 2026 help article giving 82 destinations and the current page 146.
Activation, Top-Ups and the Rules That Cost Money
| Rule | What Yesim documents |
|---|---|
| When validity starts | ⚠️ Varies by country, provider and package. The FAQ admits purchase, installation or first connection |
| Deadline to activate | 180 days on most products, including Europe and UK and the global plans |
| Africa exception | ⚠️ Immediate or deferred up to 365 days, which differs from everything else |
| Top-ups | 🚨 A supported top-up REPLACES the plan. Previous balance and validity are not added |
| Leaving the covered area | The eSIM may stop working while the balance remains and validity keeps running |
| Auto-renewal triggers | Terms §6.7 allows charging when the balance drops below 30% or one day before expiry |
| Auto-renewal incentive | 20% discount on each automatic renewal, per the help |
| MultiSIM | Buy 1 to 10 eSIMs in one order, each with its own destination and validity. ⚠️ Not one shared allowance |
| Hotspot | Supported, and shared data counts against the same plan |
| Calls and SMS | ❌ Data only. Virtual numbers are a separate rental product |
🔄 The top-up rule is the most expensive thing on this page to get wrong. Yesim’s MultiSIM guide states that a supported top-up substitutes the previous plan rather than adding to it, so your remaining data and remaining validity are not carried across. That makes the instinct to top up early, in order to build a buffer, actively harmful here. Wait until the current plan is genuinely spent. And note the related trap: if you leave the covered area, the eSIM may stop working while the validity keeps running, so interrupting use is not the same as pausing the clock.
⏱️ And the activation rule genuinely varies, which no house rule survives. Yesim’s own FAQ acknowledges that activation may begin at purchase, at installation or at first connection, depending on the country, the provider and the package. Most products give 180 days to activate and the Europe and UK page states that explicitly, while Africa offers immediate activation or deferral up to 365 days. One published review describes a twelve-month hold across the board, which matches Africa and not the 180-day products. Read the condition on the specific plan before buying. Our eSIM activation guide covers the mechanics once you have decided.

The plan rules above decide when you should buy and activate. This walkthrough shows the practical iPhone side: installing the Yesim eSIM profile, selecting it for mobile data and getting it ready for travel without replacing your primary SIM.
Installation and plan validity are separate things, so always check the specific Yesim package before you activate it. For a broader device-independent walkthrough, see our eSIM activation guide. If the profile installs but data does not work, use the eSIM troubleshooting guide.

Wallet, Refunds and Loyalty
| Item | What is documented | The condition |
|---|---|---|
| Ycoins | Internal credit for Yesim services, shown in your currency | ❌ Cannot be transferred or converted to cash |
| Refund window | 30 days from purchase | ⚠️ Requires unactivated, unused and unexpired |
| Refunds up to €10 | ⚠️ Credited in Ycoins only | As are payments originally made with credits |
| Technical failure exception | Possible with evidence | ⚠️ Must be reported within one hour of the incident |
| ⚠️ Promotional conflict | The loyalty page advertises a 100% guarantee | ⚠️ Does not match the refund policy |
| Loyalty cashback | Bronze 5% from €0 · Silver 6% after €20 · rising to 10% by tier | Credited after the plan expires, as credit not cash |
| Referral | €5 to the friend and €5 to you | ⚠️ Purchases paid entirely in Ycoins do not qualify |
| Paid trial | 500MB for one day at $0.60 | New users only. ⚠️ The Italy SKU shows $0.54 |
| Company | Genesis Group AG, Switzerland, CHE-135.623.634 | Terms dated 15 June 2026 |
💰 Two refund details that change what a refund actually is. First, anything up to €10 comes back as Ycoins rather than money, and so does any purchase originally paid with credits. On small plans, which is most of the catalogue, that means a refund is a store credit. Second, the loyalty page advertises a 100% guarantee in promotional language that the refund policy does not support, since the policy requires the product to be unactivated, unused and unexpired within 30 days. Yesim has not reconciled the two publicly. For this Yesim Review 2026, the detailed refund policy is therefore the stronger reference point. We report the detailed policy and note the discrepancy rather than repeating the promotional phrasing, which is what a reader deciding whether to risk a purchase actually needs.
🎁 And a pricing label worth correcting. Two published reviews describe Yesim as starting from $0.54, one calling it a Pay & Fly rate for France and the other a per-day price. Neither is right. $0.54 is the price of a paid trial SKU, specifically 500MB for one day, and Yesim’s general trial page shows $0.60 for the same thing. It is a first-purchase offer for new users, not an entry price for the catalogue and not a daily rate. France’s actual Pay & Fly rate is $1.80 a gigabyte.

FAQ, Yesim Review 2026
How much does Yesim’s Pay & Fly cost per gigabyte?
It depends entirely on the country, and the spread is wider than any headline suggests. Across the 170 destinations published in September 2026, the cheapest rates are $1.80 per gigabyte in the United States, Germany, France and Spain. Greece and Albania sit at $2.40, Turkey at $3.60, and a large middle group including Thailand, Italy, the United Kingdom, Japan, Mexico and Brazil at $4.80. Above that, the United Arab Emirates is $5.40, Russia and Saudi Arabia $6.00, China $6.60 and Egypt $9.00, which is five times the United States rate. One published review reports rates reaching $144 per gigabyte in Bhutan and as low as $1.10 in Ukraine, both outside our sample, so treat the range as wider still. Check your specific destination before activating, because the same wallet buys very different amounts of data depending on where you land. Verified September 2026.
What is the minimum balance for Yesim Pay & Fly?
Fifteen euros, according to Yesim’s own help documentation updated in June 2026, which states that activation requires a balance of at least €15 and instructs you to top up if you are below it. One widely-read review states the balance starts from €29, which does not match what the help says. The difference matters if you are testing the product with a small top-up. Note also that the wallet is not exclusive to Pay & Fly: the balance can be spent on other Yesim plans, which makes it more useful than a single-purpose credit but also means it is worth understanding the expiry rules before loading it. Verified September 2026.
Does the Yesim wallet balance expire?
The official sources disagree, and there is no reconciliation published. The Pay & Fly page states the balance does not expire. The top-up help article states that Ycoins expire after six months without activity. The loyalty tiers page states that cashback does not expire. Those are three different answers from the same company about the same wallet, and one published review adds a fourth by saying the balance stays valid for a full year. We report all of them rather than picking the most attractive, because which one governs is not resolvable from the pages. If you are loading a large balance for occasional trips, that uncertainty is worth factoring in, and keeping the account active is the safest hedge. Verified September 2026.
What is Yesim’s unlimited fair use limit?
Not published, and that is the honest answer rather than a gap in this review. Yesim’s unlimited policy attributes the fair use rules to its network partners without specifying a high-speed allowance or a reduced speed, and the general policy sets no gigabyte figure. One independent reviewer who tested it used around 12GB over six days without hitting throttling, while noting plainly that Yesim does not clearly disclose how much high-speed data is included. Any review quoting a specific figure for Yesim, whether 5GB a day, 512kbps or 1Mbps, is supplying a number the documentation does not contain. The policy also mentions recovery in a daily or monthly cycle rather than guaranteeing that every reduction ends after 24 hours. Verified September 2026.
Is Yesim’s Global Plus better value than Global Package?
Only if you need the extra destinations, because it costs considerably more for identical data. Global Package covers 83 destinations and Global Plus covers 146. At 40GB over 365 days, Global Package costs $82.80 and Global Plus costs $130.80, a difference of $48 for the same allowance over the same period. On unlimited the gap is proportionally larger: seven days costs $40.80 on Global Package and $78 on Global Plus, so you pay $37.20 more for the same week. The decision is therefore not about value but about coverage. Open both destination lists, find your countries, and only pay the Plus premium if your route genuinely needs the wider footprint. Verified September 2026.
How does the Yesim Unlim Day Pass work?
You buy a number of 24-hour sessions and use them within 365 days of purchase, with each session starting when the profile connects. Ten days costs $58.80, twenty costs $82.80, forty costs $130.80 and eighty costs $238.80. The arithmetic matters: at ten days that works out to $5.88 a day, against $3.16 a day for a 30-day Global Package unlimited plan. So the Day Pass is more expensive per day at the smaller tiers and only overtakes at eighty days, where it reaches $2.99. It makes sense when your travel days are scattered across a year rather than consecutive. Two conditions to know: turning the profile on in a covered home country can consume a day, and published coverage counts for it differ, with a February 2026 help article saying 82 destinations and the current page saying 146. Verified September 2026.
Does a Yesim top-up add to my existing data?
No, it replaces it, and this is the condition most likely to cost you data. Yesim’s MultiSIM guide states that a supported top-up substitutes the previous plan rather than adding to it, so your existing data balance and remaining validity are not carried over. That makes the common advice to top up early in order to accumulate data actively harmful here. Wait until the current plan is genuinely spent before topping up. Separately, if you leave the covered area the eSIM may stop working while the data balance remains and the validity keeps running, so interrupting use is not the same as pausing the clock. Verified September 2026.
When does a Yesim plan start counting down?
It varies by product, and Yesim’s own FAQ acknowledges that activation can begin at purchase, at installation or at first connection depending on the country, provider and package. Most products give 180 days to activate after purchase, and the Europe and UK page states that explicitly. Africa is the documented exception, offering immediate activation or deferral for up to 365 days. One published review describes a 12-month hold across the board, which matches Africa but not the 180-day products. Because three activation triggers and two deadlines coexist in the same catalogue, the only reliable approach is to read the condition on the specific plan before buying rather than applying a house rule. Verified September 2026.
What are the catches in Yesim’s refund policy?
Three worth knowing. A standard refund must be requested within 30 days and requires the product to be unactivated, unused and unexpired, so testing a plan and then asking for money back is outside the policy. Refunds up to €10 are credited only in Ycoins rather than returned to your card, as are any payments originally made with credits. And the loyalty page advertises a 100% guarantee in promotional language that does not match the detailed policy on the refund page, a discrepancy Yesim has not reconciled publicly. There is also a technical-failure exception, but it requires reporting within one hour of the incident and providing evidence, which is a narrow window. Verified September 2026.
Does Yesim include calls and SMS?
No. The travel eSIMs are data only, with no mobile voice and no native SMS, so calls and messages run through WhatsApp, Viber or similar apps. Virtual numbers are a separate rental product with their own pricing and conditions, and the documentation on them is not fully consistent: one FAQ limits virtual numbers to receiving messages, while the current terms allow voice and additional SMS depending on the product. Acceptance of verification codes by banks and other services is not guaranteed on any virtual number. If a callable line is a requirement rather than a convenience, check the specific number product rather than assuming the data plan covers it. Verified September 2026.
Final Verdict: Yesim Review 2026, 3.9 / 5
Yesim sells four good products and documents them inconsistently. The four modes genuinely cover four different kinds of trip, which is rare and useful. What holds the score back is that the basic figures appear differently across Yesim’s own pages in four separate places, and the one product most people find appealing, unlimited, is the one with no published specification at all.
- 📦 Predictable trip: Fixed data. Asia Pacific 30GB at €38, which is €1.27 a gigabyte, or Global Package 20GB over 90 days at $46.80
- ♾️ Heavy consecutive days: Global Package unlimited, 30 days at $94.80 and $3.16 a day, the cheapest daily rate here
- 💳 Occasional light use: Pay & Fly, but only where the rate is low. $1.80 a gigabyte in the US and Western Europe is excellent; $9.00 in Egypt is not
- 📅 Scattered travel days: Unlim Day Pass at 80 days, $238.80 and $2.99 a day, the only tier where the maths works
- ❌ Check before paying the Plus premium: $48 more for the same 40GB buys 63 destinations, nothing else
Three things to carry away. Nobody can tell you Yesim’s unlimited limit, because it publishes neither a high-speed allowance nor a reduced speed, so any review quoting one made it up. A top-up replaces your plan rather than adding to it, which makes topping up early a way to lose data. And three official pages give three different answers on whether your wallet balance expires. None of that makes Yesim a poor choice. It makes it a provider where reading the specific product page is worth more than reading a review, including this one.

This review is a documentary audit of the public catalogue rather than a field test, and is presented as such. There are no speed measurements, coverage results, latency figures or support response times from my own use, and none should be inferred.
Every price, rate, rule and limitation was read from Yesim’s own product pages, help centre articles, refund policy and terms of service, with the main collection on 14 September 2026 and price checks on 20 September. The audit covers 1,297 plan options, 170 Pay & Fly destination rates, 444 coverage entries, 58 usage rules and 44 commercial conditions. Prices are native quotations in USD or EUR with no conversion applied, because the amount charged depends on the currency selected at checkout.
Where Yesim’s own documents contradict each other, this review reports every version rather than selecting one. The Pay & Fly page states the wallet balance does not expire while the top-up help states Ycoins expire after six months without activity; the loyalty page advertises a 100% refund guarantee that the refund policy does not support; Day Pass coverage appears as 82 destinations in a February 2026 help article and 146 on the current page; and the trial SKU appears at $0.60 on the general page and $0.54 on the Italy page.
Yesim publishes no high-speed allowance and no reduced speed for its unlimited plans, so none is quoted here. Coverage counts are nominal and the specific plan’s destination list prevails over any headline figure. The company is identified on its own terms as Genesis Group AG, Switzerland, and no independent audit of that identification was carried out. Prices and terms change without notice, so always confirm at checkout.
