i have also tried different numbers to see if the problem was with the specific number. Also tried reboot and no issues sending texts the usual way
I'm not really sure what else could be wrong. You could try using the smssend command in the terminal to send a message, and see if that works, since that is what I am using:
/usr/bin/smssend -s -n NUMBERHERE -m MESSAGE
I am working on a new version that won't have smssend as a dependency, which may fix your problem.
installed the version up of smssend and its work. Cheers for your time,. Brilliant work if you cant still let us know of ur new version it would be appreciated.
