Beware

This app is a scam
IPImafidon Pboy

We love this app!

My wife and I are expats, and travel A LOT. This is the best travel sim!!! Many others make you sign up for a timeframe, and one location at a time. Not Yesim! You simply open an international account, put money in, and it’s good nearly everywhere! No lost money and the account is ready every time you travel. HIGHLY RECOMMEND!

Response from developer

Thank you for your review! We do our best to provide great service, and we’re glad you noticed our efforts!

Супер

Отличное приложение для путешествий! Очень удобно пользоваться интернетом за границей, подключение простое и быстрое. Связь работает стабильно, а сам процесс настройки занимает минимум времени. Большой плюс — возможность оставаться на связи сразу после прилёта, не покупая местную SIM-карту. Очень доволен Yesim, однозначно рекомендую всем, кто часто путешествует! ⭐⭐⭐⭐⭐
