K790i sudden corrupt txt msgs

Hey guys i am new to this forum. i did a little searching and found no definite answer so he is another attempt. for the last 2 days my phone has been acting very odd. when i turn on my phone i can receive and send 1 text message each after that i can not send any text and every message i receive is corrupt. the last update i did for firmware was last year and it was from SE corporate site. the phone works fine. i tried my sim in another phone and it is good i dunno what to do now please help me.

i am sorry if this is a repeat thread but if someone piont me to an answer i would be very gratefully

Try Doing A Master Reset First. If It Doesnt Solves Your Problem Then REFLASHING Your Phone Will Definately Do. See XS++ 3.1 Guide-Flashing,Customizing,Recovering - Top Sony Forums

Reflash you phone. Then should all be ok, again.

Nice day
