iMessage doesn’t work over cellular

[Alexkinsellakw]

On an iPhone 15 with eSIM, iMessages only sends and receives over WiFi. If I’m on cellular only, nothing sends or receives. I’ve tried toggling iMessages on and off, signing in and out of Apple ID, resetting cellular settings - nothing seems to work. Same for FaceTime. 

messages and FaceTime do not appear in Cellular Data as apps either.

First, Reset Network Settings after a device reboot and check if you can send iMessage on data

If issue persists, remove your phone number from Settings menu, then re-enter it back after a device Reboot to force a iMessage re-registration
