Text messaging is one of the most basic features of a smartphone, so it can be frustrating when your Galaxy S22 or S23 won't send text messages. There are a few things you can do to try to fix this issue.

1. Restart your phone. This can often fix minor software issues that may be causing the problem.

2. Check your signal strength. If you have poor signal strength, you may not be able to send text messages. Try moving to a different location with better signal strength.

3. Update your phone's software. Samsung releases software updates regularly to fix bugs and improve performance. If your phone is not up to date, it may be causing the problem.

4. Clear the cache and data for the Messages app. This can help to resolve any issues with the Messages app itself.

5. Reset the network settings on your phone. This can help to reset any incorrect network settings that may be causing the problem.

6. Factory reset your phone. This is a last resort, but it may fix the problem if all else fails. However, it will erase all of your data, so make sure to back it up first.

If you have tried all of these steps and you are still unable to send text messages, you may need to contact Samsung for help.

Here are some additional tips that may help:

Make sure that you have a valid SIM card in your phone.
Check that your phone is not in airplane mode.
Try sending a text message to a different number.
Try restarting your phone's network.
Contact your carrier for help.
I hope this helps!
