iMessage is not working on my iPhone 16 Pro

If iMessage isn't working on your iPhone 16 Pro, you can try these steps:

• Restart your phone: Press and hold the power button until you see "slide to power off", then scroll to turn it off. You can also try a hard reboot by holding down the Home and Power buttons for 10 seconds until the Apple logo appears. 
• Check your network connection: You need a Wi-Fi or mobile data connection to send iMessages. 
• Update your iOS: Outdated software can cause compatibility issues with iMessage. 
• Turn iMessage off and on again: Go to Settings > Apps > Messages, turn off iMessage, restart your phone, and then turn iMessage back on. 
• Check with your carrier: Make sure your carrier supports the type of message you're trying to send. For example, if you're trying to send group MMS messages, you can go to Settings > Apps > Messages and turn on Send as Text Message. 
• Check the phone number or email address: Make sure you entered the correct contact information.
