Hi,
I have just moved to HCMC and will be here for 2 to 3 years.
I bought a simcard *Viettel at the airport and have topped up about 900k into it. A local kindly helped to set some 2.5gb option for me but I am not too sure whether it is an auto-renewal plan.
Currently I am also wondering if it makes any sense to switch to postpaid. Any thoughts would be greatly appreciated!
