[Q] Cannot connect to mobile network / 3G

Hi all,
I've got an X10i to fix it. CM7 and Doomkernel had been flashed on it. It works but cannot connect to any mobile network.
I have flashed a generic and a branded rom, but it doesn't work. The phone finds the networks but it can't connect. It writes: 'your sim card does not allow a connection to this network'. I have checked it is debranded.
Could you please help to find out the problem?

[Q] Samsung Galaxy Ace GTS 5830i No mobile Network error post root

Hi Ladies & gents,
I'm new to this forum, and new to android.
Basically i was given a Samsung Galaxy ace by my brother (was on o2 network, all working fine), and i decided that i wanted to try & unlock it.
In the process, i rooted the phone successfully, and downloaded galaxy tool box, to unlock it. This was all carried out using an sd card from my pc.
After the procedure i changed sim to 3 network, and found the phone saying "no network coverage."
I checked the settings, and under mobile networks\network operators if i click on search networks, "searching flashes up for a second and thats it!
If i try select automatically it says "unable to connect to network. Try again"
The phone shows 3 out of 4 bars signal, and when i try & call someone it says "no network coverage."
Have i goofed up, as i now have a phone that works fine on wifi and everything else except to make non voip (skype etc) calls!
Please help?
Thanks in advance.

If not there fix it with HEX EDITOR. Your network connection wiil be start.
Hit thanks if I help
