Sierra Wireless LTE Modem Guide: Series Index


The Sierra Wireless LTE Modem series is a very popular choice among those wanting the maximum performance out of their LTE cellular service. The modems are extremely affordable on the second-hand market, cover a wide range of frequencies, and are all factory unlocked. You can buy just about any second-hand Dell branded EM7455, plug it in, and go. Unfortunately there is a bit of a learning curve that goes along with them, but this guide will hopefully serve to make that a short and simple process, rather than a week long process of investigation a researching.

This post is part of my Sierra Wireless LTE Modem Guide Series. If you prefer to skip the blog nature of these guides and just grab the bare features and commands, my GitHub repository will serve as the authoritative source for this entire series. Any changes or updates will occur there first.
