Note: The below steps are applicable to the iPhone and the cellular version of the iPad only.

Are You in Good Coverage Area?

Though it might not sound obvious at first, but those more-than-half signal bars may look very, very deceiving at times. Try moving closer to an open window or where cellular connectivity is better in your home or office space. Also, make sure the issue does not happen out in the open.

Contact your service provider only after you've made sure that this is not a problem from there end. In a lot of cases it can be.

Restart your iPhone or iPad

Go to Settings > Cellular > Cellular Data Options > Cellular Data Network and check to see whether or not your APN settings are all in place and up to date. You can get these settings straight from your carrier or their website. Once your settings are applied, make sure you give your device a restart for good measure.

Have You Exceeded Your Data Allowance?

Though it sounds very absurd, but trust me it doesn't hurt anyone's ego to check whether or not you've went overboard with your data allowance causing you to come to a standstill. Simply call up your carrier to find out or use their dedicated app (if any) for all the details.

Still Nothing?
