Just plug it in, run your distribution's Mobile Broadband connection wizard, and surf. It's genuinely Penguin friendly with all recent desktop oriented GNU/Linux distributions supported out of the box.

  • Experience cellular internet connectivity speeds of up to 150Mbps (keep in mind that real world connectivity varies greatly and depends on different factors including location and which provider you go with).

  • Our modem supports connecting to major US cellular networks such as: Verizon (this is one of the only Verizon certified modem chips not blocked from Verizon's new network), T-Mobile, AT&T, & AT&T mobile virtual network operators such as PureTalk.

  • Ample documentation: We provide documentation on connecting to the internet for most popular and libre (free) distributions.

  • Never worry about support after an upgrade: There are no dependencies on proprietary drivers, NDISWrapper, or other OS-loaded binary blobs.

  • Configured to start in a sane mode: We ship with our modems in MBIM mode (Mobile Broadband Interface Model) by default and QMI mode optionally (for routers). With broad support across major desktop distributions you won't have to connect and disconnect your modem in an attempt to get it to start in the right mode each time you want to utilize it or have to manually setup automatic mode switching. Simply use your desktop distribution's built-in networking utilities and avoid having to follow an otherwise complicated set of directions.

  • Reference our detailed documentation for setting up and activating a SIM card on major US cellular networks.

  • Use your new modem in a router and share your internet access with other users and devices: Our modem works in QMI mode which is the standard for many popular embedded GNU/Linux distributions targeted at routers. We have directions for using our 4G modem on libreCMC and similar popular embedded distributions.

  • The best support: Not only do we have ample documentation, but we provide end-user support so customers who have questions don't have to worry about sub-par or non-existent cellular provider support for GNU/Linux. Have a question? Just email us

Distributions and releases listed above are referencing support for the graphical networking utilities of the primary desktop environment that a distribution or release ships. In some cases earlier releases will also work, but generally not through the standard graphical networking utilities. As such users may want to check out our directions for manually setting up a cellular data connection via the terminal. When using a terminal and manually setting up a connection it may be necessary to have a temporary internet connection to install additional software (libmbim-utils).

Mageia users should note that the distribution works with the above chips when using the GNOME desktop environment only after manually adjusting the firewall.

Under OpenBSD users may need to setup the connection from the terminal (we haven't tested anything else).

Linux Mint users should be aware that we have only verified support under the Cinnamon desktop environment and not any other desktop environments nor any non-Ubuntu based versions.

All of this said even if your distribution and release isn't listed most recently released distributions and desktop environments are compatible and will work with the modems using either chip. If you have any questions about which card is right for you and/or compatibility with a particular distribution or release feel free to contact our support team.

If you intend to utilize your 4G modem with an embedded GNU/Linux distribution such as libreCMC or OpenWRT we recommend purchasing the modem already setup to work in QMI mode. This mode is currently better supported on many embedded distributions.

Some mobile broadband providers make obtaining service needlessly difficult. To ensure a more seamless user experience we're recommending these SIM cards where service is available.

Are you assembling a new computer or need to replace a damaged antenna? Besides the wifi cards themselves we also offer a number of different types of antenna.
