Hi
I did a search before posting... Failed to find VIETTEL's plans (the internet has been iffy, many pages simply won't load).
In Thailand, one could pay a fee to end the need for frequent top-up payments (TRUE).
Q: Is there such an option for VIETTEL?
Q: Do you have a link to their purchase of minutes? Say I pay in 100,000 VND, will I get more money vs a 50,000 VND deposit? (Pardon my ignorance).

For data, VINAPHONE has a 2 GB a day and 50 free minutes plan for 89,000 VND
