You need the correct internet settings to access the internet with a mobile data connection.
For most mobile networks and operators, these settings come pre-installed on your device so that you can start using
the internet right away.
You can manually check for updates to your internet settings. If you change or delete an internet setting by mistake,
reset the internet settings.
Find and tap [Settings] > [Network & internet] > [Mobile network] for more mobile network options.
