iPhone 3GS with Celcom postpaid sim, when I try to make a phone call, the call will be auto-ended in 3-5 seconds after someone has picked up the call.

I am pretty sure it's my phone failure.

When I use Maxis SIM with my iphone, it works fine.

What's the problem? I search through the net, no one has the same problem as Im having.

Need help bros.

celcom outgoing call failure, how to solve? max 5 sec then ended

AT&T iPhone 3GS cannot be activated with Universal Simcard.
Is the above statement true?

I heard they have recently updated their carrier or something. So only AT&T Sim card would work.

since when??
Expired AT&T simcard can work or not?

Hi peeps, my iPhone is locked and i need an AT&T simcard to have it activated via iTunes. Anyone has it and stays near Centrepoint, The Curve, or kota damansara?

Celcom has call forwarding every time i make a call. Sometime the call will be ended in few seconds. Do you guys have that problem too?
how to solve it? 3GS set here
