Signs of Network Issues:
- No service bars on your phone
- Error messages indicating network problems

Solutions:

- Restart your phone. Sometimes, a simple reboot can reconnect you to the network.
- Contact your service provider to check if there are any outages in your area.
2. Incorrect Recipient Number
Another common reason for SMS delivery failure is an incorrect recipient number. Even a single-digit error can prevent SMS messages from reaching the intended person.
Signs of Incorrect Recipient Number:
