Default [Solved]Problem with gsm network in all KK CM11 Roms

SMS - sending any text causes GSM signal to disappear entirely and several minutes have to go by before it comes back up and message aren't send. To clarify, i'm using a GSM service in this phone. I didn't have issues in cm10.1 and 10.2 with this. Please Help me with this .
I try change default networks in build prop, change sms center number with *#*#4636#*#* and still no luck
