3G dongle information has been removed from this page due to 3G being removed from the UK!
== Note - installing a dongle ==
To insert a SIM into a Huawei 3G dongle, for example, you will need to have a large-size SIM, so do not pop out a small-size SIM from its enclosing card. You remove a SIM-carrier tray from the dongle, fit the SIM into the tray and reinsert it into the dongle.

Nowadays though (2024) An Ethernet mobile-data router is recommended over a USB dongle as ethernet routers would offer faster speeds (eg 5G where available) and easier configuration setup.
The FB2900 models has a USB port that can be used with a 4G dongle for connectivity and/or fallback. Note: 4G dongles and some ethernet devices may have a problem with routing public IPs to the FireBrick as they act as a NAT device. In these cases using a L2TP tunnel will enable the IPs to be routed.
==Working 4G Dongles==
Many 4G LTE dongles work by acting as an Ethernet device and perform NAT between the mobile network and the interface presented to the FireBrick. These types of dongles should work OK. If your A&A IP blocks need to be routed to the FireBrick whilst on 4G then using L2TP would be a way to achieve this. We’ll be expanding this section with more details and information as we test further dongles.
==A Note on Bonding
Multiple
Using multiple dongles with SIMs from different providers may provide extra resilience in the case of one having a problem.
=Basic Config=
If you have an AAISP data SIM, the FireBrick can be configured to use this as a backup connection, by using a
The example below is all you need to get the dongle configured. If your main broadband connection goes down, the FireBrick will automatically switch to use the 3G connection, then back again once your main connection is back.
