Product Details

The Cel-Fi Go-M Mobile Signal Booster Kit is a single-carrier system designed for use in cars, trucks, RVs, boats, and other vehicles. The Go-M current supports Verizon, AT&T, or T-Mobile and can only boost one carrier at a time. While this may be seen as a negative to some, the benefit is that single carrier boosters can be significantly more powerful than multi-carrier boosters giving the Cel-Fi Go-M a full 65 dB of gain compared to a maximum of 50 dB for multi-carrier boosters. 65 dB of gain is the same strength that you would typically find in a mid-sized building system, so you get a ton of power with this booster. This means you can stay connected in more areas while covering a much larger area inside of your vehicle.

The Cel-Fi Go-M is housed in a NEMA 4 Rated enclosure so it’s protected from water and dust making it suitable for every situation ranging from a Search and Rescue Vehicle to a Minivan with a kid's leaky cup! And the Go-M’s digital signal processing and echo cancellation algorithms allow the outside and inside antennas to be closer together without shutting down from oscillation/feedback.

The WAVE app from Cel-Fi unlocks the full power of the booster and allows you to see exactly what it is doing. You no longer have to decipher at a few LED lights to know what’s going on, the WAVE app will show you. The app can also be used to register the booster and to reconfigure it to support a different carrier or to set it to stationary mode where the gain increases to 100 dB which is perfect for larger vehicles while parked.

Why the Cel-Fi GO M?

  • More powerful than multi-carrier boosters, for the most coverage inside with a weak to moderate outside signal.
  • Maximum uplink power to ensure that the signal from the vehicle gets back to the distant cell tower.
  • Can be configured to support a different carrier as needed using the free smartphone app.
  • Can be converted to a stationary booster when not moving giving you a full 100 dB of gain which is ideal for RVs, Boats, and other large vehicles.
  • Works wirelessly. No physical connection to your phone required.
  • Supports multiple phones and all carriers at the same time.
  • Everything you need is included in the kit.
  • Fewer dropped calls
  • Faster Internet data speeds
  • Better voice quality
  • Texts that send quickly
  • Longer battery life

Your purchase is covered by our 60-day money back guarantee, so you can try it risk free, and our friendly, US-based technical support team is standing by to assist with anything you need. Your equipment is also covered by a 2-year manufacturer warranty, for extra peace of mind.

Recommended For

The Cel-Fi Go M is the ideal solution for anyone who only needs to support for one carrier and wants the most powerful system available for maximum coverage and performance.

How it Works

The Cel-Fi Go M starts with a donor (outside) antenna that is typically mounted to the roof of the car. The Go M comes with a Magnetic Mount outside antenna, but an optional permanent screw mount antenna is available for situations where a magnetic antenna will not work.

The outside antenna receives the existing outside cell signal and sends to over a cable to the Go M amplifier. The amplifier analyzes the signal and intelligently boosts it. The amplifier is connected to a server (inside) antenna which rebroadcasts the boosted signal to the inside of the vehicle.

The entire process also works in reverse by boosting the signal from your phone and sending back to the tower. This gives you a strong and reliable cellular connection for voice calls and fast 4G LTE data.

Estimated Inside Coverage

The strength of your existing outside signal, measured in the location where you plan to mount the outside antenna, has a direct impact on the amount of inside coverage you'll get from a signal booster. The table below shows how much coverage you may get depending on your outside signal strength:

Existing Outside Signal Strength Estimated Inside Coverage
Strong (5 Bars) Most of the Vehicle
Medium (3-4 Bars) Most of the Vehicle
Weak (1-2 Bars) A Few Feet from the Inside Antenna
None (0 Bars) No Coverage

Please Note: It is important to remember that there are many factors that impact the size of the inside coverage area, so actual results may vary from these estimates.

Additional Signal Booster Kit Options

The Cel-Fi Go M is a great option for larger vehicles and can be configured for use in RVs, Boats, Trucks, and more. Please contact us for more information on customizing the Go M for your situation.

Will this Work for my Phone and Carrier?

The Cel-Fi Go M is designed to boost only one carrier at a time. The booster can be reconfigured to change which carrier is boosted, so you’re not locked in to just one carrier, but it will only boost the one carrier at a time.
