We used it for a trip to Thailand. The eSIM was a huge help; it worked quickly and without any issues. I definitely recommend it! It's so you don't have to waste time on SIM cards upon arrival.★

Guest User2026-01-29
The internet works great, it flies. It's very convenient that you can share it with other devices. The e-SIM installation is very easy. I've bought the 10-day 50GB package several times; it's the best option not only for using instant messaging and social media but also for watching something online.★

Guest User2026-01-29
Very quick verification through the QR code in the description of the Esim. You just need a passport and wifi/hotspot. Note that when typing the ICCID you should not use the first 6 numbers you see, start from the 7th. Easy installation on iPhone, internet seems to be working fine. Calls also work.★

I'm so glad I chose this particular E-SIM card. I was able to easily call internationally, which isn't possible with every E-SIM card. The internet also worked perfectly, and I could share my data. I'd happily buy another one if I need it.★

I traveled solo as a woman from Vietnam to Cambodia by land, staying in Cambodia for 9 nights (2 nights in Phnom Penh, 1 night in Kratie, and 6 nights in Siem Reap) ♪ This eSIM made my trip a fulfilling one ^ ^ I'll use it again!
