Fast Facts About This Product:

  • This amplifier is best for: Providing the most signal possible to a single 2G/3G device that has an antenna port. This amplifier INCLUDES a 6" magnetic mount antenna, which is great for vehicle use, but other antennas can be used instead - many customers purchase an antenna separately (see above) and simply replace the included antenna with the antenna of their choice.
  • All-in-One Kit? NO - a 6" mag mount antenna is included, but most users opt to purchase a different antenna instead; all users will need an adapter to connect the amp to their device (sold separately)
  • Compatibility: 800mhz/1900mhz networks, which are used by most 2G (voice) and 3G networks in the USA, including:
    • Verizon 2G/3G
    • Sprint 2G/3G
    • AT&T 2G/3G and HSPA+ (which shows up on your device as "4G" - NOT LTE)
    • T-Mobile and Cricket voice only
    • Does NOT work with LTE for any carrier or AWS (T-Mobile 3G/4G)

IMPORTANT SIGNAL INFORMATION: If you're purchasing an amplifier for use at one specific location, we strongly recommend doing a site survey first to determine whether the amplifier will help you and to give you an idea of what kind of results you can expect from it.

If your signal is extremely poor (-108db or worse), an amplifier may not be effective - there must be some usable signal available for the amplifier to boost. Conversely, if the signal is too STRONG at your location (-50db or better), the amplifier may shut down to avoid interference with the tower.

Are you stuck in a weak coverage area or traveling in a vehicle and want to improve your signal as much as possible? A good antenna is a must, but if you want the best possible signal, a direct connect signal amplifier is the answer. A direct connect signal amplifier plugs in between your external antenna and your mobile broadband device to provide the best possible signal wherever you are.

The Cellphone-Mate SureCall™ CM-M2M-19 is a high-performance amplifier that boosts the signal of most 3G modems or cellphones by up to 10x. It will make you feel like you’re right next to the tower, without actually being there. This AC powered amplifier is FCC-Approved, and provides the maximum output power allowed by the FCC for use by non-broadcasters. The new 6V design is more-efficient than comparable 12V designs, and runs safer and cooler.

Package Includes:

  • CM-M2M-19 19 dB direct-connect amplifier
  • 6" CM200-S 3dB magnetic mount antenna (must be mounted to something magnetic in order to be effective - suction cup window mount available separately) with 9.75' cable attached. Many users prefer to disregard this antenna and purchase a different antenna instead.
  • CN-CM-CN-06 SMA/Male to FME/Male adapter (for users who want to use an FME antenna instead of the included magnetic mount antenna)
  • 6' RG-58 cable with SMA/Male and FME/Female connectors (to connect your adapter cable to the amplifier)
  • AC Power Supply
  • Velcro and Screw Mounting Kit
  • User Manual


  • Frequency Range: Uplink: 824-849 and 1850-1910 MHz / Downlink: 869-894 and 1930-1990 MHz

I have had the cellphone mate for several weeks now. I use it for my USB760 internet connection. The second it was plugged in I went from 0 bars to full bars and the speed increased expidentially. This was money well spent. I live in a rural area that does not have access to DSL. I am so very pleased with this product. My work is a piece of cake. Thanks to Kevin who was my email contact. He was great!!!!

I ordered this product after a great deal of research and contact with 3G's exceptional staff (kevin). My internet, VZ USB760, had no reception. Initially, we installed an external antenna. That gave us connection 10 times slower than dial up and always dropped the connection. The cell phone gets ZERO signal inside and limited outside unless you walk down into the field. My back and forth with Verizon led me to research. AND, lo and behold!!!! The cellphone mate was connected as per instruction and the desktop computer started. The VZ connection went from previous no bars, limited & spotty signal to 4 bars in EVDO & 1xRTT. I connected to the internet and glided through all my work. We are not involved in social networking or games online. We utilize this pc for research and work etc. THANK YOU 3G for immediately and effectively correcting my problem. Verizon could learn something from the 3g staff on how to effectively communicate etc.

I've ordered from 3Gstore for years and the last time I contacted them since I needed to fix a reception issue at an underground parking garage. I was quickly refereed to a combination of products that would solve my issue. I initially thought I would have to run a cable and mount an antenna outside but that was not needed. A proper Cellphone-Mate amp and the 4dB Wall Mount Whip and my problems are now solved - went from -99dBm to -75dBm.

This made a HUGE difference in my signal strength. We went from 1-2 bars to full strength by adding this. We're using this with AT&T HSPA+ network as we don't have LTE available.

This has been a gamechanger! We're so Thankful to have come across this device. We live about 1.5 miles away from a Sprint tower. Without the amplifier we get 3-4 bars (rarely 5), -84 dBm, 24 RSSI. With the amplifier we get a SOLID 5 bars, -73 dBm, 31 RSSI. That's probably the best part, the consistency, before, our download speeds would seesaw up and down and up and down, now they are consistent. Usually throughout the day it's about 60 kilobytes/second or so, in the morning and evening the speeds are actually faster, 100-120 kilobytes/second. It's been such a blessing to have this.

Occasionally, the Sprint signal will go down to 0 bars, these outages are intermittent, seemingly random (although it does happen more in the evening than any other time), and generally resolve in about 15-30 minutes, if that long. We don't think this is any fault of the Direct Connect Amplifier, since similar things used to happen before, but with a higher frequency.

The amplifier is great though, it's small, doesn't get hot (barely gets warm), easy setup. It's been running easily for weeks continuously without any problems. Excellent product at a great price, it could make a world of difference!

Works very well for me. From the get go I notice a major improvement in signal strength.

I was not sure the antenna and amp option would help me but after doing a site survey with my Mifi 4510L from Verizon I thought it might. I also purchased the amplifier and my signal went from a poor -95 to a good -55 on average. I am in a remote area of Missouri by Lake of the Ozarks. I can not get a more reasonable signal and internet as there is nothing else available. In the summer I can not take an extra day at out Lake house and still get my work done. Thanks 3G Store for helping me have more vacation time

I installed this amplifier along with the 18" Building Mount Omni Antenna with 15' of cable between the two. I am very impressed with the results. I was getting -95 to -105 dBm signal (signal strength around 25%) before and now receive -65 to -72 dBm (100% signal strength).

I live in a rural area where cell is the only option for internet. The tower is 6.5 miles away.

Works good full signal 7 miles from tower.EVDO suffers during foggy weather.

Works well in rural Queensland, Australia 50miles from nearest town. Fittings all good for Australia only need to by a transformer in Australia to run off the main electricity supply.
