A800 Call Failed Problem!!
 

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???

I have solved one by full eep reset *2767*2878#

you don't lose nothing if you try

b.r.

check if the IMEI is correct first !

if the code gave by THECULT doesn't worke try to rehot RF part espacially PA an mixter !!!

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 .
