3. APN Setup

3.1. Overview

GSM and LTE-based Skywire modems can be setup to use different APNs. APNs are

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

connection. Accordingly, in order to connect to a cellular network, it is crucial to ensure

that the proper APN is set on the device.

If you activated your Skywire modem on

https://go.nimbelink.com

, use the APN's

defined in Section 3.2. For data plans not activated through NimbeLink please reach out
to your carrier for APN configuration details.

3.2. Common APNs 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.

4. Common Next Steps

Once the network setup and testing is complete, you are ready to start developing with

your Skywire modem. Common application examples include sending and receiving

SMS messages, FTP file transfer, TCP/UDP packets, and using the modem with an

external microcontroller, such as an Arduino. Please consult these application notes on

the Skywire Development Kit page (

http://nimbelink.com/skywire-development-kit/

) or

your Skywire-specific page for specific examples of each type of operation.
