Hi I have the same problem and have tried all of this but I am still unable to send text messages (I can receive them). iMessages are fine. Text messages are not 

Hi ​@Stephen McGurk,

I am so sorry to hear that you are facing issues with your normal text messages. Try these steps. 

1. Go to Settings → Messages
   - Turn iMessage OFF, wait 30 seconds, then turn it back ON
   - Make sure Send as SMS is ON
2. Turn Airplane Mode ON for 30 seconds, then OFF
3. Restart your phone
4. If it still doesn’t work:
   - Take out your SIM card and put it back in
   - If possible, test your SIM in another phone
5. Last step: please contact your carrier and ask them to check or refresh your SMS service, since you can receive texts but not send them

Please let me know if it still doesn’t work.

Regards,

Gemma M
