Texts not sending or receiving from another iPhone

Re: "Texts not sending or receiving from another iPhone"

Between Apple devices: Should be no trouble sending messages back and forth using wi-fi, as long as your provider / modem-router / is reliable.

Check the number has not been accidentally blocked on your iPhone.

Check the recipients details are listed correctly in your Contacts app.

Else: Wondering whether or not Apple Support's troubleshooting article can help:

If the recipient recently changed from an Apple to an Android phone, then messages will need to go back and forth using SMS via cellular data (provider charges may apply).

If needed: View or change cellular data settings on iPhone - Apple Support
