IOS 16.2 problem

Try this

• Check with your carrier to see if the type of message you’re trying to send, like MMS or SMS, is supported.
• If you’re trying to send group MMS messages on an iPhone, go to Settings > Messages and turn on MMS Messaging. If you don't see an option to turn on MMS Messaging or Group Messaging on your iPhone, then your carrier might not support this feature.

Who is your carrier?

If it’s Verizon…

When you activate an iPhone 14 on Verizon their automated system does not set up MMS correctly. To fix it you need to call Verizon tech support (611 on your phone), tell the nice representative who answers that you need to speak to a senior tech to fix a problem with the provisioning of MMS on your account; specifically, the MMS setting needs to be synced to the network. This is a universal problem with the iPhone 14 provisioning by Verizon, so the tech should know how to fix it. And hopefully the 1st tier reps will eventually learn also. [ Credit to Lawrence Finch ]
