Turn Off Your iPhone’s Cellular
If turning off your Wi-Fi didn’t work, you can try turning off your cellular data instead. Turning your iPhone’s cellular off and back on again will make sure that your iPhone tries to connect to the strongest signal it can get a hold of. Plus, it might get rid of any issues with your current connection.
Here’s how to disable cellular on your iPhone:
- Open the Settings app.
- Go to Cellular.
- Turn Cellular off.
And that’s it. Wait a few seconds and turn Cellular back on again to see if that fixed the problem.
