Configure dual APNs
Some cellular carriers offer a dual APN feature that allows a SIM card to be provisioned with two
separate APNs that can be used simultaneously. For example, Verizon offers this service as its Split
Data Routing feature. This feature provides two separate networking paths through a single cellular
modem and SIM card, and allows for configurations such as:
n
Segregating public and private traffic, including policy-based routes to ensure that your
internal network traffic always goes through the private connection.
n
Separation of untrusted Internet traffic from trusted internal network traffic.
n
Secure connection to internal customer network without using a VPN.
n
Separate billing structures for public and private traffic.
n
Site-to-site networking, without the overhead of tunneling for each device.
