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! ⭐⭐⭐⭐⭐
