Question [Q] Strange Call Problem ! Can you help me !

Hello,
i have an Galaxy S3 LTE UNLOCKED

so the problem started after i tried to unlock it using " *#197328640# "

and selecting " UMTS " etc as you know...

but this method didn't work for me so i requested a code to unlock from the internet, then it unlocked now..

but i can send messages but cannot make any calls ?

i tried every thing and i turned on " Perso SHA256 " again but no chance..

sms work great but no calls >>>> any suggest ?

Thanks

In that case as per faqs and guides you need a service centre repair.
Providing you have read the faqs and guides and followed relevant steps then their is nothing left bar a service repair .
sim
sim holder
modem
csc
APN
You have checked them all .
Factory reset the phone and flashed stock firmware .
