After 1 year got accumulated credit rm120 because need to topup rm10 every month

Btw redone got pay per use @RM0.01 per 200KB, credit will gone if accidentally turn mobile data on

Onexox with rm10 topup can get 2 years 4 months validity + extended validity

Can a postpaid number converted to prepaid number? I'm moving abroad and planning to keep my number. but the cheapest postpaid plan still too much for me to bear. i was wondering if i can still keep my current number without buying a new prepaid number?
