My new iPhone 14 will not let me send or receive group messages with SMS on , MMS ON AND GROUP MESSAGES ON ?

Hi smg53,

It seems you're having trouble with Messages and we want to help.

If you're not receiving specifically SMS and MMS, it's likely you're having a carrier issue.

Are you able to make or receive phone calls?

Take the steps here, especially contacting your carrier:

- Try to restart your iPhone or iPad.

- Check your network connection. To send a message as iMessage or MMS, you need a cellular data or Wi-Fi connection. To send an SMS message, you need cellular network connection. If you turn on Wi-Fi Calling, you can send SMS messages over Wi-Fi.

- Check with your carrier to see if the type of message you’re trying to send, like MMS or SMS, is supported.

The above is quoted from the article you came from: If you can't send or receive messages on your iPhone or iPad

Your carrier should be able to solve any service issues you might have for your carrier services like SMS and MMS.

Thanks for using the Apple Support Communities.
