[Galaxy J5] What if it only show one APN, only the selected one?

[Herald347]

My Samsung J5 phone can't access internet through my mobile data but does through Wi-Fi and it only shows one APN that's the selected one, what must I do?

Welcome to Android Central! Which carrier do you have? Is the APN for that carrier? Are you sure the APN settings are correct?

If the APN settings are wrong (every carrier uses a different set), most Samsung phones don't allow you to delete the only APN, so add one that has your carrier's information, then back up once and select the new one as the one to use.
