Cannot receive text message in iPhone 11

Hello, basil140! Thank you for posting to the Apple Support Communities. We understand your situation and how you have been unable to receive messages using your iPhone 11. We’re happy to take a look and help provide you with a solution. 

There are several troubleshooting steps that we’d suggest starting with. Please follow the instructions in this Apple Support article first: 

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

If you continue to notice the same problem after using these suggestions, we can help you more. Can we continue by knowing if this seems to be an issue with both iMessages and SMS messages? 

Does this problem only occur when certain contacts attempt to message you? Or does this appear to be an issue for everyone who tries to contact you? 

We look forward to helping you reach a resolution. 

Cheers!
