The signal is very good in Saigon, very easy to scan & use, it's just a shame that it can't be used for calls because it's not a Vietnamese eSIM, the settings have to be roaming but for the internet it's very good & fast, because I live in Vietnam, this eSIM is only for tourists, not for those who stay long term.

After 3 days of use, 5G still appears but the Internet cannot be used and I cannot top up to buy more data. For the last 2-3 days, I have no Internet to use.

Believe me it's one of the worst eSIM I ever purchased. My friend bought the other eSIM and works perfectly, while I only can connect to whatsapp text ONLY (even you can't use whatsapp call)... super slow connect to google, even grab service. The first day it's already lost connection for est. 30 minutes. Second day suddenly it's super slow connection, and I was in HCM city district 1! what a joke. DONT BUY THIS SERVICE!

GO King eSim delivery is very fast and the signal is OK around HCM city

Redemption and setup was quick and easy. Connected upon arrival in a breeze!

its very difficult too connect

The signal is not very strong, even though there is a 3G signal in Sa and in Hanoi there was 3G.

Worked well during my trip in the north and south of Vietnam. The staff was very quick to respond and so helpful when I had the problem of using an eSIM for the first time. I recommend it!

Really cool and very easy to use
