How can I enable mms
Greetings, naeem172.
Welcome to the Apple Support Communities. It sounds like you have some questions about using Messages on your iPhone. Messages are important, so we can understand why you’d want more info.
To start, check out: Use Messages on your iPhone, iPad, or iPod touch
To enable “Send as SMS”, navigate to Settings > Messages and enable Send as SMS. There is also an option for MMS Messaging.
If this is already enabled and you’re unable to receive MMS messages, you may need to contact your carrier.
Don’t hesitate to reach back out if you have questions.
All the best.
