Reviews: Thailand | 5G eSIM | Day Pass/Total Package | 24H Billing | 1-30 days | QR code

We bought two esim cards for 20 days for a trip to Thailand. We had doubts right up until the last minute about the internet and download speed for that price—around 529 rubles. Everything was great. We used them for the entire 20 days and they never let us down. We activated them immediately upon arrival, and everything was up and running within 3-5 minutes. Very convenient. I recommend them.

The internet was decent, and the speed was sufficient. The package was perfect for everyday tasks and navigation at a good price.

Installation takes just a couple of seconds with just one click in the app, and the connection is very good. I'll be using it again.

Very convenient, I wish they'd written down how to top up my account; I had to run around a lot. The answer was simple: there are top-up terminals at all the stores.

This isn't my first time using an e-SIM from Trip. I've used it for several countries and was surprised by how easy it was to switch without any intervention on my part. Thanks for the detailed instructions. Quick installation and connection. Never let me down. Thank you!
