Can’t text myself

Hello Alberrbenstein,

Are you able to text everyone else (and receive messages from others), aside from yourself, without issues?

This page has a handful of steps that can help with issues sending/receiving texts: If you can't send or receive messages on your iPhone or iPad - Apple Support

If you have issues with Messages after you set up a new device

If you experience issues like conversations in Messages showing up as separate threads or sent messages appearing as green message bubbles instead of blue message bubbles when you set up a new device, update your settings using the following steps:

1. Update your device to the latest version of iOS or iPadOS if needed.

2. In the Settings app, tap Cellular. Make sure that your phone line is turned on. If you use multiple SIMs, make sure that the phone number you want to use is selected and turned on.

3. In the Settings app, tap Messages. Turn iMessage off and then back on.

4. Tap Send & Receive.

5. Tap the phone number that you want to use with Messages.

Be sure to also check for any available iOS updates. The current latest one is iOS 16.0.2: Update your iPhone or iPad - Apple Support

Cheers.
