Guest User2026-02-28

Connecting to the network is quick and easy, installation is simple, and most importantly, the price is very affordable. After comparing many service providers, TRIP is still the best. I highly recommend it.

Guest User2026-02-28

It worked perfectly from the start, no need to contact customer service at all. The links are excellent; accessing Instagram, finding maps, and instant sharing are all no problem!

Guest User2026-02-27

Previously, you had to enter the information each time you installed the app, but recently it has become so much easier that you can just press the "Install" button and it's ready to use right away! It's so convenient because you can turn it on after the plane lands at your destination and it's ready to use right away!

I used this in KL, Bangkok and Shanghai. Overall the signal was ok. Sometimes we do get a drop out but it’s not often. We managed to use all social media platforms with this eSIM at Shanghai. Only thing is if you want to hail a ride you’ll need a number for it in china.

Guest User2026-02-22

It's easy to use, simple and convenient, and has plenty of data! It's fantastic!
