I bought a new Mobifone sim card at the airport, but how to put it on and check its balance ? And how to refill ?
Press *100* then press the code in the card that you bought ( you should to scratch the card to see the code that was hide) then press # and call.And for checking the balance : press *101# and call. and for the promotion balance press *102#
For All telecom companies in Vietnam (Viettel, Vinaphone, Beeline, Mobifone), if you want to refill: *100*numbercard(12degits)#okIf you want to check balance: *102#ok
