my problem is, the iphone 3gs is purchase form maxis, but i using a celcom postpay line (i think this should not be a problem, because its officially unblock for all operator), i found it when i using my iphone make a call to other people (all kind of operator inc fix line), when they receive my call, the line will automatic cutoff or after few second it will cutoff. it happen every day. the ratio is i make 10 call, at least 4 call facing this kind of problem.

this happen only appear on my current use number, i try to put other celcom or maxis number, its ok, no problem appear.

i was make complain to celcom regaring my problem, after few day they come back to me, tell me line no problem, ask me to change the sim card. but after changing sim card, still appear the same problem
