Product Description

SureCall Fusion2Go Max Vehicle Cell Phone Signal Booster.

SureCall Fusion2Go Max is the most powerful in-vehicle cell phone signal booster available on the market. It boosts 2G, 3G, 4G LTE, 5G E cell signals for all cellular devices and carriers in the US, Canada, and Mexico for best performance in both urban and rural environments.

SureCall Max uses Extended Range Technology (ERT) to capture cell signals at their strongest point outside the vehicle, improving call reliability and data performance inside the vehicle. It also features the strongest transmit signals back to the cell towers to keep you connected in the weakest signal environments.

Per customer feedback over the phone, this is the best vehicle cell booster on the market regardless of your vehicle type. We call this our 50 mile cell phone booster because customers have complimented that it has helped them get connection to cell tower 50 miles away. Designed, assembled and tested in USA.

Leaving all other variables aside among all brands and models for a moment, the reason for its best performance may be that it has a unique technology called Extended Range Technology (ERT) which boosts signals right at the top exterior antenna even before sending it to signal amplifier for being amplified again. You must try it to believe the improvement - we will give full refund up to 60 days from receipt, if not fully satisfied.

We think of SureCall Max Fusion2Go kit as a "Fusion2Go 3.0" with double the power on the low bands, which are the main frequencies used in rural areas where the majority of mobile boosters are used. It is equipped with Extended Range Technology (ERT) that will help maintain connectivity even further off the grid, while improving Signal to Noise Ratio (SNR) which provides a higher quality signal that translates to better data performance.

Please note limitations and reason for those limitations.

Limitation: If you plan to purchase another set of exterior and interior antennas to move the base unit from one vehicle to another easily, that is not possible with this kit. Exterior antenna cannot be detached from signal amplifier base unit. Therefore, the main base cannot be moved over to another vehicle without removing exterior antenna with its cable.

The reason for this limitation is due to its extended range technology (ERT) which makes this the most powerful simultaneous multi-carrier vehicle cell signal booster that it is. With this technology, its exterior antenna acts as a pre-booster. Thus, its exterior antenna boosts signal after catching it to pump maximum signal inside vehicle for the main booster to amplify (again!). ERT helps enable this kit to provide higher uplink and downlink power than any other multi-carrier cell phone booster.

Therefore, to ensure that this exterior antenna with built-in prebooster is not replaced inadvertently or by mistake with another basic antenna making this kit useless, its exterior antenna cable has been permanently attached to the base.

If you need a vehicle cell signal booster kit that can be transferred from one vehicle to another quickly without removing its exterior antenna & cable, then please consider SureCall Fusion2Go 3.0 or SureCall Fusion2Go 3.0 RV cell phone booster kit (Non-ERT). Fusion2Go 3.0 and Fusion2Go 3.0 RV kits offer slightly lower uplink & downlink power but they are such that you can buy an extra set of their antennas for installation in another vehicle so that you can unscrew both antenna cable connectors from base unit to switch the main booster unit easily from one vehicle to another without having to remove and re-route their antennas and cables.

Only 4 Steps to SureCall Fusion2Go Max Vehicle Cell Booster Set-Up:

SureCall Fusion2Go Max Vehicle Cell Phone Signal Booster Set-Up Diagram


Place the magnetic-mount antenna on the top of your vehicle, preferably toward the back, Ensure that the antenna has at least a 12-inch radius clear of obstructions and other radiating elements, such as a radio antenna. *For non-magnetic vehicle body, use the adhesive option included in package. Run the cable from the outside antenna across the car’s roof and into the car. To hide and protect the antenna cable, carefully pull down the door seal, run cable underneath it and push the seal back into place. Note: The outside antenna must not be collocated or operating with any other antenna or booster.


Identify a location for the inside antenna on or near your front dashboard that is: (1) Within 2-3 feet of typical cell phone location, (2) At least 8 inches (20cm) from cellular devices and (3) At least 4 inches (10cm) from metal. Peel Velcro backing and apply to a clean dry surface in your chosen location. Or try this - Use the free vent clip provided with your product as a mounting surface then simply clip to an air vent. Please note that if buying kit with desktop antenna, the separation between the desk top antenna and the external antenna needs to be 20 feet to 30 feet, in order to prevent oscillation.


Select a well-ventilated location for the booster that is away from excessive heat, direct sunlight, and moisture. We often suggest installing beneath a seat or within the front console. Connect the cable from the outside antenna to the connection marked OUTSIDE and connect the cable from inside patch antenna to the connection marked INSIDE. Hand tighten the connections and secure any loose cable.


Connect the DC power cord connector to the signal booster and the adapter end to the cigarette lighter adapter to your vehicle. Once all connections are connected, turn the power switch on the adapter to ON. The Power LED will illuminate to indicate that the signal booster is ready for use. Note: When your car is off, turn the power switch to OFF to keep the booster from continuing to draw power to your vehicle. Place a call in a location you have previously experienced poor signal and confirm that your phone is receiving a boosted signal. Normal operation is indicated by Green LEDs (both flashing and solid). In the event Red LEDs appear, antenna adjustments may be needed.

What is the difference between different styles available?

While the exterior antenna cable that runs from outside ERT antenna to signal amplifier main unit is a RG-174 10 feet long coax cable, the length of coaxial cable that runs from signal booster base unit to inside antenna varies with each kit. The Patch Antenna Kit includes RG-174 10 ft. inside cable from amplifier to inside antenna (same length as exterior antenna cable length). However, the Whip on-amplifier antenna kit, table-top antenna kit, and wall-mount panel antenna kit includes low loss RG-240 20 ft. cable which is needed for longer runs in bigger vehicles such as RVs and Motorhomes. More importantly, the Gain provided by respective style/type of interior antennae within each kit varies as follows:

  • Patch Antenna Gain (recommended for car, truck, SUV):
    LTE-A (AT&T) = 1.1 dBi. LTE-V (Verizon) = 1.1 dBi. 800 MHz = 1.1 dBi. 1900 MHz = 3 dBi. 1700 MHz = 3 dBi. 2100 MHz = 3 dBi.
  • Amplifier-Mounted Whip Antenna Gain (recommended for Small Size RV, Motorhome):
    LTE-A (AT&T) = 1.2 dBi. LTE-V (Verizon) = 1.2 dBi. 800 MHz = 1.2 dBi. 1900 MHz = 3 dBi. 1700 MHz = 3 dBi. 2100 MHz = 3 dBi.
  • Tabletop Antenna Gain (recommended for Medium Size RV, Motorhome):
    LTE-A (AT&T) = 2.5 dBi. LTE-V (Verizon) = 2.5 dBi. 800 MHz = 3 dBi. 1900 MHz = 5 dBi. 1700 MHz = 4 dBi. 2100 MHz = 5 dBi. Please note that to prevent oscillation, the separation required between the table top antenna and the external antenna is 20 feet to 30 feet.
  • Wall Mounted Panel Antenna Gain (recommended for Large Size RV, Motorhome):
    LTE-A (AT&T) = 7 dBi. LTE-V (Verizon) = 7 dBi. 800 MHz = 7 dBi. 1900 MHz = 10 dBi. 1700 MHz = 10 dBi. 2100 MHz = 10 dBi.

Optional Cable Lengths.

Integrated cable from exterior antenna to signal booster base unit will not vary from ten feet cable provided. Interior antenna cable length of 20 ft. is provided with all Marine / RV kits (not the Patch Antenna Kit for car/ truck/ SUV that includes the shorter 10 feet cable which is enough for most cars, trucks and SUVs). However, internal antenna cable lengths can vary with purchase of any of the following cables. Please note that shorter the cable length you use, the better - because shorter lengths incur less Gain loss. If you plan to buy a cable for extending your existing cable length instead of replacing it, know that you will need the connector SC-CN-11 to connect it to your existing cable. The following cables are low loss, weatherproof, heat-shrunk and tested to perform at their best.

  • 10 feet SC-240 Cable with FME-Female/N-Male connectors (SC-004-10-FN).
  • 20 feet SC-240 Cable with FME-Female/N-Male connectors (SC-004-20-FN).
  • 40 feet SC-240 Cable with FME-Female/N-Male connectors (SC-004-40-FN).

Questions & Answers


Ask a Question
  • Vacant mountain property. I cannot use my tablet but I can use my phone and even get on the internet. But I want to use my cell phone as a hot spot or use my carrier Verizon Hotspot MiFi and enable other devices to call or use the Internet. We are camping while we clean this lot so we can build on it in a couple of months. There is no residence. And it is for a temporary situation not permanent. Suggest an option. And I can produce ac/ or dc though a solar panel generator.

    For your situation, since there is no house, we recommend getting this vehicle cell signal booster (Fusion2Go MAX) and installing it in your car for use of your cell phone placed in the vehicle. It has unique technology that boosts signal within exterior antenna itself and then again when signal reaches base unit (signal amplifier) providing more amplification boosting signal of all carriers at the same time than other kits.   Simply roll windows down when you're not in your vehicle, and place phone (or even multiple phones) right against the booster's interior antenna with its ringer volume to maximum. This way, the phone will stay connected to the network consistently and it will monitor incoming calls as well as allow you to make calls (you can turn on speakerphone and still keep it against interior antenna for maximum strong connectivity to cell network of all carriers simultaneously). Remember to place exterior antenna atleast 1 foot away from windows to prevent oscillation (feedback) between exterior and interior antennas because the vehicle roof will work fine as a barrier needed between the two antennas - this is required for it to work at optimum level.   The booster kit includes the standard 12V DC power jack that you can insert in DC power supply socket of your vehicle to power it. You can also hardwire it to the car battery or DC power source using DC Hardwire Assembly.   If not fully satisfied or you no longer need it, we offer full refund on equipment if returned within 60 days of purchase date. We think you will like it and would want to keep it in the vehicle permanently when on the go to have clear cell reception for clear calls and fast mobile data.   Please note that we offer financing with no interest option if paid in full within 12 months - Choose "Klarna" at checkout for more details.

  • Thank you, I received my Fusion2GoMax cellular signal booster the other day. I contacted my cellular provider here in Canada (Telus) to register my booster, but was told by their representative that Telus would not register the signal booster (as recommended in the Fusion2GoMax documentation). My request: Can you confirm please that Fusion2GoMax is compatible with the Telus network? I was told by the Telus technical representative that Telus operates on the 4G LTE 2100MHz, 1900MHz, 700MHz and 850MHz frequencies. I see the Uplink Frequencies and Downlink Frequencies on the Fusion2GoMax specification sheet that came with the booster, and at least some of those listed frequencies above appear to be supported. I am a lay-person and have very little understanding of cellular phone operations. I appreciate you taking the time to assist me with my enquiry.

    In Canada, there's no requirement to register with your Carrier. That registration part only applies to users in USA. Yes, it covers Telus frequencies and those of the rest of the Canadian carriers such as Rogers, Bell, and Freedom Mobile.

  • What splitters are compatible with a SureCall Fusion2Go Max?

    The splitters are not compatible with the fusion2go MAX. The gain is too low to handle any kind of split.

  • I am a private contractor delivery driver. I use my own car. Often in certain parts of my city my iPhone gets little to no service on the app that feeds me my work information. I need help ASAP! What would you suggest?

    Customer feedback has led us to believe that Fusion2Go Max (first option with interior patch antenna) would be the best solution. Technically, Cel-Fi GO with exterior magnet mount antenna with 18 inch cable should also get the job done.

  • I purchased a Fusion 2Go Max for my RV a couple months ago from you folks. It is working great! My question is: It would be ideal if I could add about 5 feet of cable to the exterior antenna for placement purposes. I know the existing cable is permanently fixed to the antenna, but can extra cable be added between that cable and the main amplifier? Or, would that additional cable decrease performance? Thank you for your time and assistance.

    Yes, you can safety add additional cable at end of exterior antenna cable before connecting it to the signal amplifier. The part number we recommend is 005-4-FF which is a 4 feet FME extension cable, because the next threshold available is 10 feet. Not too much degradation to the signal since 4 ft. is not long at all. You can quite safely add even a longer FME extension cable, if needed. Just know that keeping it as short as possible is best because attenuation will accrue with longer cable.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

For non installation-included kits: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
