Comments on Viettel Tammi for Android

★☆☆☆☆ Mohamed ElBazzaz · Nov 5, 2026
EDIT. Vettel stopped topping up via the bank, it forces you to use this dumb cheap cooded app that the English interface doesn't even allow you to top up. Worst app, worst verification. Changed my device because they shut down 2g, to volte did imei VERIFICATION 20 times at the store and still my sim got locked. Staff were not even helpful and no one had a clue what to do. The in-app ID verification didn't work as well. AVOID THIS COMPANY AND THEIR SERVICE
★☆☆☆☆ Fine FN · Oct 28, 2026
Keeps asking for a camera, contact and microphone, can't find where my plan or balance history is, there is no English, can't paste a full phone number with a country code. One of the worst apps I have ever seen, completely useless, will have to go to the office since it is unclear how to top up my plan. Why change one piece of trash 🗑️ for another? The new app is even worse than the previous, at the previous I was at least able to find something. Also burns the battery like crazy.
★☆☆☆☆ Khang Trần · Oct 21, 2026
Not sure reason but changing the app name from myvietel and spam message, advertisements to user to download is a terrible idea, I do not care vie tel migrate technology or whatever I will leave 1 star before using anything in it as it annoyed me, very stupid migration campaign, the head of migration strategy should be dismissed even first login with otp bug 2 times when copy and paste, new UI look terrible to my point of view
★☆☆☆☆ Aaron Mejia (Flame Fingers) · Nov 3, 2026
This new app doesn't have options to buy, switch or cancel packages. I can't check my home internet account status either. What is the purpose of changing apps? This makes no sense! You finally added English, but since the app doesn't do anything, who cares?
