Yesim: great service at competitive prices with solid support
I've been using Yesim for over a year now. I went with the Pay&Fly plan, which lets you pay as you go (that's perfect for me—no prepaid bundles needed).
Setup for both the app and eSIM was super simple and intuitive, at least on iPhone. If you run into any issues, their 24/7 chat support is lightning-fast and helpful.
I've traveled with it to the UAE and Vietnam—internet worked flawlessly both times: stable, high-speed connection right from airport arrival, no hassle or setup dances required. Recently switched phones and asked for eSIM migration help via the app chat—they sorted it in literally 5 minutes.
Highly recommend—great service at competitive prices with solid support!
