APN is short for 'Access Point Name'. This is the name of the connection that your provider uses to connect your device to the internet. If your device has problems connecting to the mobile internet of your provider (so not with a WiFi network, but 4G or 5G network), look at the APN settings of your phone. Often the APN settings are set automatically, but this doesn't mean they are always set correctly. In the steps below we explain how to change the APN settings on your Android device.
