Yesim Pricing and Plan Types
Yesim offers local single-country plans, regional bundles, global packages, unlimited options, and a pay-as-you-go model called Pay & Fly. Durations start at one day, with weekly, biweekly, and monthly options also available. Validity begins at purchase, though deferred activation lets users delay the start by up to 12 months. Pricing sits in the mid-range tier overall. The best value comes from Ycoins cashback rewards, which return 5% on every purchase, and Pay & Fly’s per-megabyte billing for light or variable usage.
Is Yesim legit?
Yes. Yesim is run by Genesis Group AG, a Swiss company registered as CHE-135.623.633. It scores 4.3/5 on Trustpilot from 2,948 reviews. Refunds are available within 30 days if the plan hasn’t been activated or used. Two caveats: Trustpilot has removed fake reviews from Yesim’s profile, and recurring complaints cover unlimited-plan throttling and weak signal in Turkey, Tunisia, Egypt and Cyprus.
Yesim's Pros and Cons

- Trustpilot flagged Yesim for guideline violations and removed fake reviews, raising legitimate questions about the authenticity of its online reputation scores.
FAQs
Is Yesim a good eSIM provider?
Which is better, Airalo or Yesim?
It depends on the trip.
- Choose Yesim for multi-country trips, heavy data or unlimited plans, and flexible pay-as-you-go use. Yesim also adds a VPN and virtual numbers.
- Choose Airalo for short single-country trips and small data amounts (1 GB from $4.50), and for the larger catalog and user base. Airalo has 200+ destinations, 43,894 Trustpilot reviews, and a 4.1 rating against Yesim’s 4.3.
- On price, independent comparisons say Airalo is cheaper on small plans and Yesim on larger ones. That comes from secondary sources only.
Who owns Yesim and where is it from?
Yesim is a privately held Swiss eSIM provider. Dmitri Verbovski and Max Pankratov founded it in 2019, and Genesis Group AG (Switzerland) operates it. Genesis Group itself was founded in 2012.
Does Yesim provide an app?
Yesim has an iOS and Android app for buying prepaid eSIM data plans for travel. Plans are local, regional and global, and the app also has Pay & Fly. It includes a VPN and virtual phone numbers, and one eSIM profile is reused for every purchase and top-up.
Does Yesim Support Calls, SMS, and Local Numbers?
Yesim does not include native voice calls or SMS with any of its eSIM data plans. All connectivity is data-only, and Yesim recommends using VoIP apps such as WhatsApp, Viber, or Telegram for voice and messaging over data. As a partial workaround, Yesim sells virtual phone numbers that can receive inbound SMS for verification purposes, but these do not support outgoing calls or messages. Travelers who need native cellular calls and SMS should consider Airalo’s Discover+ global plans, which include talk time and texting alongside data. Ubigi and select local carrier eSIMs also offer voice and SMS bundles as integrated options
