Internet access requires strong network coverage. If your network signal is marked as “emergency”, blank or unstable, you will not be able to access the internet or make calls.

To check if there is a network, check the signal bar in the status bar. You can ask people close to you to check if they can connect to your mobile network by phone.

You can lose network coverage, especially if you are far from the city or in a basement. Also, while travelling, you may not get a reliable network until you reach a particular destination.

If you’re in a place with poor network coverage, you’ll have problems with signal reception. This usually happens when you are in a remote location or an isolated environment. When your phone detects this, it simply moves to another place with a better network signal.
