I can't send text messages on my Samsung S8+. Android version 8. I have already reset network and it didn't help. It's been 6 days
Are you still having difficulty sending SMS?
If it's working now, don't forget to let the Community know what worked!
Let's get to the bottom of this together!
What other tests have you tried? Does rebooting your phone help? Are you able to send an SMS to yourself?
Lastly, could you let us know the exact error message you're getting?
