Best connection, did not have any problems with it even when we went island hopping. Was connected the whole time. Though would advise one to do the authentication before flying put as it can be a bit complicated.

Guest User2026-02-25
This was my first time using an eSIM card. I liked it: it was easy to register and activate on my phone. I got it for 13 days and used it in Thailand, sharing internet with a second phone. The signal was good, and everything loaded quickly. I used local messaging apps to order food and groceries. I also used Russian messaging apps for video calls home.
