  1. Jasonteakwondo

    powerful and constantly updated with lots of community support and customization!

  2. layton

    Amazing modem! It works great with the WE826 on AT&T. It is supported by AirVantage too, so you can update it over the air.

  3. aosmer

    Works well with AT&T and T-Mobile. Currently using this to lock onto B2 on AT&T, and speeds are great. Only concern with this would be if you need B14, or B66, otherwise this is great.

  4. Rippentorn

    I purchased one of these here nearly 2 years ago. It is STILL rockin strong today (02/2020)

    It keeps 5 different firmware images (1 for each major carrier and one generic firmware) and is very very easy to get connected to carrier networks. It has been established as a go to card for a few years now.

    I’ve used it in a WG3526 router and a WE826 router.

    With the right antenna and signal tweaking I’ve gotten over 100Mbps out of mine.

  5. silenceattack

    Very easy to set up. Used it with a WRT1900ACS and a USB enclosure. Practically plug and play!

  6. Bryson04

    Very Satisfied with this product. Unless you are already completely familiar with this product. don’t bother buying used, unless you can truly trust the seller. New is the way to go if you are just getting started.

  7. Erik Olson

    I installed this Sierra Wireless MC7455 in a WE826-T2 Router with GoldenOrb Firmware on verizon. Very easy to setup with tutorial. Modem speeds improved greatly with external antennas installed in attic.

  8. Caleb Carmichael

    Works out of the box with WE826-T2 and 2018 version of Golden Orb on ATT. Can’t wait to upgrade antennas and see how much speed is possible. Received in 3 days to Florida.

  9. sxracerb25

    Just received today. Setup was very simple and is working great so far.

  10. Wisconsin1000

    Greatest product on the market! just buy! LTE fix is the best!

  11. matt

    Put this in the WE826 router. Easy to use and it works great for my LTE connection

  12. reitz27

    Installed in a WG3526. Installation was fast and easy and with a Sprint SIM I’m getting 80Mbps down. Excellent customer service and support!

  13. Collin Chan

    Worked perfectly in the USB to Mini PCI-E adapter enclosure. I use it with a Linksys WRT1900ACS with GoldenOrb firmware. It’s been extremely easy to set up.

  14. homeworkburgler

    Purchased this card after some reviews and help from the forums and facebook group. Price was right and I felt I could trust since the forum and facebook group had such great help. Will be ordering again.

  15. deewhylan

    Great modem, but a lot to learn. The LTE Hacks forum is very helpful though.

  16. Kiddster64

    Switched from a r910 to this bad boy and it was like a night and day difference. No more random disconnects and very simple to install with the instructions provided on the site!

  17. bendsley

    I installed the Sierra Wireless MC7455 in a WE826 Router with WiFix Firmware on AT&T. Very easy to install and setup with LTE Hacks tutorials. Modem has very good speeds and is very stable.

  18. bendsley

    I installed the Sierra Wireless MC7455 in a WE826 Router with WiFix Firmware on AT&T. Very easy install and setup with tutorials. Modem has very good speeds and is very stable.

  19. zbigb

    I used this inside a USB To Mini PCI-E Adapter Enclosure to verify my SIM card and carrier service would work before investing in antennas and router. The tutorial on how to set this up was straight forward, helpful and worked just as written. I pulled the sim card out of my Franklin R910 and used it with the sim card adapter to compensate for the size difference. My download speeds went from 5Mps to 30Mps, and that is just with the small omni antennas included with the adapter! I am looking forward to trying this with a couple of decent panel antennas set up in MIMO configuration with the MC7455 mounted inside a router.

  20. jlh62478

    Installed in WE826 router. Very easy to install. This combination works very well for me.

  21. willmw

    Working flawlessly for me on Sprint Unlimited plan. Recommended.

  22. Tick Tech

    Nice fit for the Turris Omnia router. Works well with Verizon and AT&T and gets carrier aggregation on both networks. Good modem.

  23. texpaul

    Awesome modem that fits great in my WG3526 router. Setup was very easy thanks to the tutorials and setup has given fast, reliable connection!

  24. Todd Eichel

    I installed this modem inside a WG3526 router. Works very well with this setup. Easy to set up and has excellent speeds. I have plans in the future to upgrade to the EM7565 which should even boost it more.

  25. JamesHarris

    Installed this modem in a WE1026-5G mobile router. Easy to install and program even for someone with no technical experience. The only issue I have with this modem is the small size of the connectors. I resorted to using a magnifying glass like recommended on the instructional material and they popped on easy once properly lined up.

  26. Melvin King

    Worked perfect on my wg3526 build. Fast! Good instructional tutorials on the forum for programming the mc7455 and the overall building process.

  27. Jflex113

    I’ve used two of these cards on two different routers. They have both worked extremely well on my Linksys wrt3200acm and my Netgear WNDR3700v4. They far exceed any hotspots speed and are much more reliable, especially when equipped with a proper antenna setup as well.

  28. Stacy McGee

    Used one in the WG3526 router. A lot faster than our ZTE hotspots. Don’t forget to install antennas or else it won’t connect to the internet.

  29. Bill James

    Installed in a WE826 LTE router to use with AT&T. This modem has fast download speeds and very stable connections. Beats the hotspot we were using hands down.
