A800 Call Failed Problem!!

[MC Harami]

Hi i had a Samsung A800 given to me that wouldnt allow me to make calls, so i changed the IMEI on it.
Now when i put an O2 sim it works fine but when i insert an Orange sim i try making a call and then it says CALL FAILED.
What can i possibly do now???

1. check your new imei of your phone ,first.
2. you can reset your phone call barring operation, thru phone menu.

try this operation before any thing .
