If you can't send or receive messages on your iPhone, iPad, or iPod touch

Specifically, take a look at these suggestions:

Try these steps first

1. Make sure that your iPhone, iPad, or iPod touch is updated to the latest version of iOS.
2. If you have an iPhone or iPad (Wi-Fi + Cellular), check for a carrier settings update.
3. Check your network connection. To send a message as iMessage or MMS, you need a cellular data or Wi-Ficonnection. To send an SMS message, you need to have a cellular network connection. If you have Wi-Fi Calling turned on, you can send SMS messages over Wi-Fi. Contact your carrier for more information.
4. Check with your carrier to see if the type of message you’re trying to send, like MMS or SMS, is supported.
5. If you’re trying to send group MMS messages on an iPhone, turn on MMS Messaging. If you don't see an option to turn on MMS Messaging or Group Messaging on your iPhone, contact your carrier.
6. Make sure that you entered the correct phone number or email address for the recipient.
