Multiple USB Dongles can used via a USB hub - however the benefits of bonding multiple 3G are small, as you'll typically be contending with yourself and so there will be little or no added bandwidth. |

Using multiple dongles with SIMs from different providers may provide extra resilience in the case of one having a problem. |

If using AAISP, then the options for IPv6 routing on the [[:Category:Control Pages|Control Pages]] allow an IPv6 block to be routed to a tunnel endpoint if the main routing (ie ADSL/FTTC) goes down. This means IPv6 can be routed to the 3G dongle if the main broadband(s) go down. The MTU will be limited though. |

Sometimes we don't want the dongle to be online 24x7 and want it turned off outside of office hours. |

Here we ping an IP on the LAN, behind the FB2700, and get the ADSL router to re-sync. The ADSL went down, the 3G kicked in with only a single ping lost, then shortly after the ADSL came back on and took over the routing again. |
