Supplementary Service error: general error/ Call failed

Hi, guys please help, am very frustrated as I am not able to make or receive any calls or sms's. Everytime I try, i receive an immediate message saying " supplementary service error. or "call failed". When everybody else calls me it goes straight to voicemail.  


I tried the battery pull, I did the security wipe, I called the service provider, nothing seems to work. has any of you ever experienced this? what did you do? please advice. 


Under "manage connections" on the main menu, i checked the "service status" and it says not connected under "mobile voice". Other applications work very well, such as facebook, whatsapp, bbm and google talk.

Hi Makhasane


Welcome to BlackBerry Support Forums



                          There are no specific  workaround regarding this error but From what I have noticed  in most cases this " supplementary Service error " is resolved after replacing a new SIM , So I prefer you should try that option Or if your device is still under warranty contact your service provider.
