Can this be fixed without doing a whole system reboot

[AC Question]

I CAN SEND MESSAGES ON "HANGOUTS"
BUT I CANT send A TEXT MESSAGE TO ANYONE
I can RECEIVE TEXTS....
ANY IDEAS?
* I was told by someone that I would have to do a whole system reboot.
is there any other way?

Hi, the reboot is a bit extreme, have you checked with your carrier to make sure there isn't something wrong with your text allowance? also, have you tried sending a text through your stock messaging app and not hangouts?
