Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

Great! I registered it before flying, and when I arrived, I could activate it right away. I could use the internet to its fullest potential. It was very convenient, inexpensive, and easy to install.

Excellent reception! No problems on the Ha Giang Loop and Ha Long Bay. And cheaper than Airalo and similar airports.

As someone who travels skit across Asia, I’ve used numerous eSIM Apps and providers and this was probably the best value Sim I’ve obtained to date. Vietnam 5G 10Gb data for 14 days at £3.42 👌
