5.1 APN Configuration

5.1.1

Overview

APNs are used by devices and cellular networks to initialize and properly set up a

cellular connection. In order to connect to a cellular network, it is crucial to ensure that

the proper APN is set on the device.

If the Skywire Nano was activated on

, use the proper APN

from the table below. For data plans not activated through NimbeLink please reach out
to your carrier for correct APN configuration details.

5.1.2

Common APN's and Their Respective Carriers

The table below contains a list of common APNs and their respective carriers.

It is important to use the APN that corresponds to the proper carrier and the specific IP

address configuration. Failure to do so will result in failed cellular network connections.
