NOTE: From time to time we may find the EM20G to sell to our customers. These are rare and hard to find now. If this listing shows it in stock, it likely will not be available for long. These modems are not guaranteed to be new or unused.

Quectel EM20 is LTE Advanced category 20 module optimized specially for M2M and IoT applications. Adopting the 3GPP Rel. 13 LTE technology, it delivers maximum data rates of 2 Gbps downlink and 150 Mbps uplink. Designed in the M.2 form factor, EM20 is compatible with Quectel Cat 16 module EM16 and future 5G module, which will facilitate customers to migrate between different categories.

EM20 is designed for global (i.e. EM20-G) and nearly cover all the main stream carriers worldwide.

EM20 supports Qualcomm¬ģ IZat‚ĄĘ location technology Gen8C Lite (GPS, GLONASS, BeiDou, Galileo ). The integrated GNSS greatly simplifies product design, and provides quicker, more accurate and more dependable positioning capability.

A rich set of Internet protocols, industry-standard interfaces and abundant functionalities (PCIe interface/USB drivers for Windows 7, Windows 8/8.1, Windows 10, Linux, Android/eCall) extend the applicability of the module to a wide range of M2M and IoT applications such as industrial router, home gateway, STB, industrial laptop, consumer laptop, industrial PDA, rugged tablet PC, video surveillance and digital signage, etc.

NOTE: The current modems are new Engineering Samples with the newer Firmware Revisions: EM20GRUR01A08M4G and/or EM20GRUR01A07M4G.  Production versions DO NOT exist.  They may or may not be compatible with the some version builds of WiFiX/GoldenOrb/ROOter without first downgrading the firmware to EM20GRAR01A06M4G per THIS tutorial.

UPDATE:  Our newest WiFiX firmware supports all EM20-G firmware revisions.


NOT RECOMMENDED for use with the M2M NEXG H721 due to this router's high rate of burn out failures.  We will warranty NO modems that are used in the M2M NEXG H721 router.

IMPORTANT:  Exercise extreme caution while installing MHF4 connectors to the modem antenna ports.  The ports are delicate and easily damaged.  Assure that the MHF4 connector is perfectly centered, level and aligned with the modem port.  The MFH4 connector will then snap into place using minimum pressure. Do not apply excessive force.  A damaged modem connector port is not covered under warranty.

It is strongly recommended to invest in a quality power strip surge protector (i.e., APC, Belkin,…) to use behind a router and/or electronic equipment.¬† This will help protect against Transients (momentary spikes/surges in voltage or current) that can be detrimental to expensive equipment.¬† Transient damage to modems are not covered under warranty.¬† Protect your equipment!

  1. crazyhairdrummer

    Upgraded with this little guy from a Mofi4500SIM4 Model. Much more band for you dollar in this package! Combine this with the WG3526 router from here and you got yourself a MACHINE! It supports 4×4 mimo antenna configurations for more speed and a crap ton of Carrier Aggregation! If your tower is capable, this modem is the BEST option for any build I have ever seen!

  2. premansh

    Upgraded from EC25-AF to EM20-G. Best decision of my life. Speed went from 10 Mbps to 70+ Mbps with MIMO and AC. Please note that this does not support band 71 for T-mo

  3. tmoffett

    This modem is the cats meow when it comes to speed. This modem blew away my old MC7455. My speeds have increased by 50% from my old modem to the EM20-G. If you are looking for the fastest modem, this is the one. Thanks Jim for providing really great prices and super fast shipping!
