For the third time for no reason I cannot send sms from my 8100 pearl.
The other times after a few days I could send them again.
After trying to send a msg it says " Protocol Error"
My simcard works fine on another 8100 pearl and sends out sms.
T-mobile says they are not aware of any problems on the network and it could be a problem with my BB.
Is there a way to check it myself if there is an error somewhere?
