My iPhone sometimes likes to play dead.
You can't phone me and messages cannot reach.
Make a call from my phone, recipient phone will ring, but my phone is not connected, no any sound, and when you answer my phone, i can't listen.

Im wondering is my iphone problem or is sim card problem after i cut my sim card into micro sim and moved in to iphone.
After few hours its not functioning, it recovers and normal.

Why is this happening?
I have to check every time whether its functioning well by making a call to someone.

Help please. =(
