Glad you found our rates easy and great. Enjoy your travels! 🌍.
Good E-sim option
Thank you. The app is user-friendly and the e-sim worked well. Too bad I had booked more from OMIO but the codes for free data can only be used once upon registration.

Glad the app felt user‑friendly and the eSIM worked smoothly for you. It’s a shame the free‑data codes from OMIO can only be used once. If you need more data later, you can easily get another plan in the app. ✈️📶.

Easy to use, only install once then buys data and use anywhere (some other eSIM providers require you to install a new eSIM every time) can convert unused data to credits towards next purchase. Highly recommend!
