What is APN?

APN is an abbreviation for "Access Point Name" and is an identifier that allows smartphones and tablets to recognize which network they are connected to, and plays a very important role in mobile communications.

Regarding APN settings, the mainstream is basically automatic (Auto-APN), so in the case of eSIM, most of the time it is completed just by scanning the QR code. Therefore, there is not much that the user needs to be particularly aware of.

However, in rare cases, it may be necessary to manually configure the APN settings depending on the version of the device used by the user and dependencies with the telecommunications carrier at the destination of the trip

Conversely, unless there are no other problems or you have no special purpose, be careful not to touch things unnecessarily and change settings without understanding Please.
