Call and sms not working
Not able to phone or sms. However it works fine for mails and whatsapp in wifi mode
I would first try your SIM card in a known working phone. I would also try a known working SIM in your blackberry.
If you can get SMS and signal on the other phone, then something is wrong with the blackberry.
A blackberry phone? Maybe you can try to shut it down and then turn it on mins later.
