It's simple. Upon arrival in Vietnam, connect to Wi-Fi at the airport, scan the eSIM barcode, and follow the instructions to activate the SIM card.

We were satisfied with the quality of the internet; we didn't use up the entire package in five days, but we didn't use it much; we wanted to live without gadgets.

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.

Everything works great anywhere. Registration is quick and easy, and you receive instructions on how to set it up and a code by email. I recommend it.

Reviews: Asia 10 Destinations 5G eSIM | Japan, Thailand, Vietnam, Indonesia, Korea & More | ChatGPT | 1–30 Days | Instant QR
Guest User2026-01-11
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.
