Answer to "Not getting cellular service"Try resetting iOS network settings. Turn the iPhone off and back on again. This can often resolve cellular data failures and it’s pretty simple: (1) Open the Settings app and go to ‘General’ followed by ‘Reset’ (2) Tap on “Reset Network Settings” and enter the passcode to confirm you wish to reset and clear out all network settings on the device – this will ditch wi-fi networks so be prepared to enter wireless network passwords again (3) Exit out of Settings and go back to the Home Screen (4) Now hold down the Power button and turn the iPhone or iPad off (5) Wait about 10 seconds and hold the Power button again to turn the device back on When the device boots back up, try to use an app with cellular data again. It should be working at this point.
