im currently digi user and wanted to chnage my line to Maxis and planing to change prepaid to postpaid .My question is can i buy phone and postpaid for new user or have to use postpaid for few month to buy the phone becoz some say can change on the spot some say have to wait which is real ?

I suppose you are not porting over. If not, no reason why you cannot sign up a contract to get a phone on the spot. However, I suggest you look at other telcos' deals including your DiGi's. I believer most of them are better. Good luck.

can you explain me more details maybe PM me more better TQ

Your query is answered. Please do some legwork/homework...check with the telcos.
