We can't really fault the service or support
We had a couple of issues setting up and the support was first class, friendly and helpful and we eventually got going
We back in Nam in August and will certainly go with Vietell again
Very happy with my Viettel eSIM
So easy to set up and very detailed instructions. Worked first time! Would recommend!
I am satisfied
The esim worked well from the moment I landed in Vietnam to the moment I left. Visited Ho Chi Minh city, a resort near Nha Trang, Hanoi, and Ha Long Bay. It was spotty as we got really far out on the Bay cruise but I honestly didn't expect it to work at all out there, so beat expectations.
