Can't make outgoing calls. Baseband issue?

[Pierrot Lunaire]

Hi, a friend gave me an old LG P500 phone to play around with. It had a stock ROM on it.
I put my SIM in, phone showed I have service but when I try to make calls it won't let me. It just disconnects in less than a second.

So I flashed a custom rom (GSNAP 1.5) to check if that might fix the issue. It didn't, exact same issue.
Phone shows it's connected to my service provider, DATA actually works but can't make outgoing calls.

Any speculations or help?

Thanks!

can you receive calls? if no then probably hardware issue.

Its network issue.. your phone is okay!!
Call network customer care!!

Well I didn't check if I can receive calls...

I don't really care that much as to call my customer service to get it to work. I have a working phone.
This is a friend's phone and he wanted me to get it working.

I guess I'll let him try it with his SIM card. Maybe his will work.

By the way, could it be that the phone might be network locked but it just doesn't say that for some reason?

Tried a different SIM card, didn't solve the issue. Same problem.

I'm not sure it's a service provider issue.

may try flashing the official rom using kdz . might be some issue with the libraries.

I flashed the official V20c with KDZ... Still a similar problem but now it shows a message when trying to make an outgoing call: "Divert Activated"
