Yesim has carved out a clear niche in the travel eSIM market: unlimited data at competitive prices. While Airalo wins on breadth and Saily on privacy, Yesim targets travelers who need reliable, high-volume data without worrying about running out mid-trip. Here is our honest assessment after testing Yesim across multiple countries.
What is Yesim?
Yesim is a Swiss-based eSIM provider that focuses on unlimited and high-volume data plans for travelers. Unlike marketplace models like Airalo, Yesim operates as a virtual operator — they buy wholesale capacity from carriers and resell it under their own brand. This gives them more control over pricing and often allows them to offer genuinely unlimited plans where competitors impose daily caps.
The service covers 120+ countries, with particularly strong offerings in Europe, Turkey, and Southeast Asia. You purchase and manage everything through their mobile app, which is available on iOS and Android.
Coverage and speeds
Yesim covers 120+ countries, which is narrower than Airalo's 200+ but still includes every major travel destination. Their European coverage is particularly strong — Yesim Europe plans cover 30+ countries with a single plan, and speeds consistently hit 30–60 Mbps in our testing across Germany, Spain, and Italy.
In Southeast Asia, we tested Yesim in Thailand and Vietnam and recorded speeds between 20–50 Mbps. In Turkey, performance was excellent with 40+ Mbps on average. Coverage in Africa and South America is more limited — check their app for specific countries before purchasing.
The key differentiator is that Yesim's unlimited plans are truly unlimited in many markets. Where Airalo's "unlimited" throttles after 1–3 GB per day, Yesim often maintains full speed throughout. This makes a real difference for remote workers, video callers, and anyone streaming content abroad.
Pricing and plans
Yesim's pricing structure is straightforward. They offer both capped plans (1 GB, 3 GB, 5 GB, etc.) and unlimited plans. The capped plans are competitively priced — often matching or beating Airalo. The unlimited plans are where Yesim really stands out, typically costing $20–35 for 7 days or $40–70 for 30 days depending on the destination.
For travelers visiting multiple European countries, Yesim's Europe unlimited plan is one of the best values on the market. One purchase covers 30+ countries with genuinely unlimited data — no daily caps, no throttling in most cases. Compare this to buying separate plans for each country and the savings are substantial.
Payment is handled through the app with credit card, Apple Pay, or Google Pay. Plans activate immediately after purchase, and you can install the eSIM before your trip to be connected the moment you land.
App experience
The Yesim app is functional but not as polished as Airalo's. Navigation is clear — you browse by country, select a plan, and purchase in about two minutes. Data usage tracking is available but updates with a slight delay (roughly 15–30 minutes), whereas Airalo updates in near real-time.
Customer support is available via in-app chat and email. Response times averaged 20–40 minutes in our testing, which is acceptable but slower than Airalo's 10-minute average. The app is available in multiple languages including English, German, French, and Russian.
One notable feature: Yesim includes a built-in VoIP service for voice calls and SMS. This is useful if you need to make calls to local numbers without a physical SIM. Call quality is decent over a stable data connection, though not as reliable as a native call on a physical SIM.
Pros and cons
Strengths
Truly unlimited data. No daily caps in most markets — rare among eSIM providers. Strong Europe plans. 30+ countries with one plan at competitive pricing. Built-in VoIP. Voice calls and SMS without a physical SIM. Swiss privacy. Company based in Switzerland with strong data protection standards. Competitive pricing. Often cheaper than Airalo on per-GB basis.
Weaknesses
Smaller coverage. 120+ countries vs Airalo's 200+. App less polished. Functional but not as sleek as competitors. Slower support. 20–40 minute response times vs 10 minutes for Airalo. Inconsistent speeds in some markets. Africa and South America coverage can be patchy. No loyalty program. Unlike Airalo's Airmoney, no rewards for repeat purchases.
Who should choose Yesim?
Yesim is the best choice for travelers who need high-volume or unlimited data. Digital nomads, remote workers, and anyone who streams, video-calls, or tethers heavily should seriously consider Yesim. It is also the strongest option for European multi-country trips thanks to their unlimited Europe plan.
If you need coverage in more exotic destinations (Pacific Islands, Central Africa), Airalo is the safer bet. If privacy features matter, Saily offers NordVPN integration. But for raw data volume at a fair price, Yesim is hard to beat in 2026.
Our verdict
Yesim has found its lane and runs it well. The unlimited plans are genuinely useful — not just a marketing gimmick with hidden throttling. The app could use polish, and support response times could improve, but the core product delivers. For data-hungry travelers, especially in Europe and popular Asian destinations, Yesim is our second recommendation after Airalo.
