Check Your Coverage Area
Always make sure you aren’t the only one having a problem with your cellular service. It’s possible that the area you’re on doesn’t have cellular network coverage.
It’s also possible that, if you’re traveling internationally, you didn’t set your device for data roaming. Here’s how to turn it on:
- Go to Settings.
- Tap on Cellular.
- Tap on Cellular Data Options.
- Toggle Data Roaming on.
