Default [Q] Help needed! I bought my third I337 however it is giving me network problems!

I just bought a used I337. It was on firmware UAMDL.

The problem that I have with this phone(i337 on UAMDL) that I just got is that it does not establish data connection. It will only do so when I call somewhere.
However as soon as the phone is left alone and go idle for couple minutes then it would drop data connection again.
Only way to re establish data connection is by dialing a number to place a call.

Anybody know how to fix this annoying problem?

I have also noticed the original owner made a copy of efs back up in the internal sd card.
I wonder why he created such back up. Could this be related to the issue that I am having?

I have 2 other i337 in the household that are pe rfectly fine.

IS there anything that I could do to fix the phone that I just bought.

Please help!

Have you Odin'd the stock firmware? I'd do that with a used phone I bought.

Thank you. It sounds silly but this solved the problem.

I don't know why it wanted me to reset or re input APN when it was set to pick it up auto and it did when placing calls.

Now it picks up connections auto and stays on.
