Product Description

SureCall EZ 4G LTE Plug & Play Signal Booster For Homes (EZ4G) up to 2000 sq. ft.

SureCall EZ-4G LTE is a fully indoor cell signal booster kit (without need for outside home / building antenna). It is a revolutionary cell phone signal booster for homes and offices up to 2000 square feet. It sets up in minutes, delivering unrivalled signal boosting power like no other comparable cellular amplifier in the market. It also has an elegant plug-and-play design that will enhance your home decor.

Sure-Call EZ4G boosts cellular signal indoors for all North American carriers without the need to drill holes or mount an antenna outside. Dropped calls and slow 4G LTE data speeds are history, as the EZ 4G provides clear and consistent coverage for all cellular devices in 1 to 2 rooms, up to 2,000 square feet. Designed, assembled and tested in USA.

This easy install window cell signal booster is ideal for apartments, basements, offices that have no access to roof but strong signal at least in one spot, probably near a window. If no cellular signal anywhere indoors, we do not recommend this kit because it will not work for you.

Since it cannot catch strong signals that usually exist outside mostly on the roof, there needs to be a line of sight to the cell tower from the window - for it to catch signals needed to amplify and broadcast.

If there's very weak signal or no signal everywhere indoors, we highly recommend FCC Certified Signal Booster with External Antenna that should work if there's at least some cell phone service provider signal outside where you can place exterior antenna.

SureCall EZ 4G cell phone signal booster for home is an incredibly simple yet effective wireless booster system that allows multiple users to enjoy increased reception and 4G capabilities. It is designed to be installed within minutes, and features a plug-and-play action that does not require the outside installation of an antenna, yet still offers powerful signal boosting of voice calls, text, 3G, and 4G LTE. It provides signal coverage for 1-2 rooms in your home or small office, with a built-in antenna to improve data performance for all mobile users within up to 2000 sq. ft. range.

With Sure-Call E-Z 4-G, you can reduce the number of missed and dropped calls, increase data speed, and improve cell phone signal with ease. Sure Call EZ4G is the easiest way to boost your cellular signal, 3G and 4G LTE performance.

Top Features!

Improves cellular reception in 1 to 2 rooms. No rooftop antenna required. Enhances voice, 3G and 4G LTE signal strength. Cuts down on instances of dropped calls and poor conversation quality. Increases speeds of texting, email, Internet and streaming - Supports multiple simultaneous users. Can be installed in 15 minutes.

Who Is It For?

Anyone who wants to be able to get better cell phone reception for Voice, Texting, 3G, and 4G LTE in a single room or two small rooms can benefit from the SureCall EZ 4G Five-Band Home Cellular Signal Booster. Because there is no roof antenna, this system is especially ideal for apartment dwellers, and other renters who cannot make changes to their roof, but still want to get better reception inside of their homes.

How Does It Work?

With the SureCall EZ 4G Five-Band Home Cellular Signal Booster, you place a large round antenna by the window of the room where you have good reception and want to improve reception farther away. The window antenna receives the signals broadcasted by all of the carriers from all of the cell phone towers in the area and then amplifies them by up to 72 decibels. The amplified signals are transmitted in the room by a desktop unit that must be positioned at least 30 feet away from the window receiver where there's weak signal you want to improve. Smart phones, tablets, mobile hotspots, and all other cellular devices then receive the signals from their specific carriers.


  1. An antenna built into the back of the booster communicates with the cell tower while it sits in your window (either booster attached directly to window glass using the provided adhesive, or placed on the stand provided to set the booster on the window sill).
  2. The booster amplifies the existing cell signal and sends it to the tabletop antenna.
  3. The table-top antenna rebroadcasts the signal indoors to all mobile devices within range.
  4. The booster amplifies outgoing cell signal back to the tower.

What Does It Work With?

You can use the SureCall EZ 4G Five-Band Home Cellular Signal Booster with:

Any smartphone or tablet model that has 3G & 4G LTE connectivity. Any U.S. or Canadian cellular carrier. The system works with 700 MHz, 850 MHz, 1900 Mhz, and AWS 1700/ 2100 MHz frequencies.

Why Is It Unique?

The SureCall EZ 4G Five-Band Home Cellular Signal Booster has a number of innovative features that make it the best indoor-only wireless booster of its kind. Some of its unique features include:

Goes into dormant state when not being used, so that you can limit energy use. Auto Gain Control allows the unit to self adjust.

While more and more people are choosing to eliminate their home’s landline, having a clear and consistent cell phone signal in the home is essential to stay connected with family and friends.

Regardless of where you live, your home’s building materials and distance from cell towers can obstruct cellular signals from entering your home leaving some missed or dropped calls and slow 4g LTE data.

Introducing the EZ4G by SureCall. Sure-Call EZ-4G differs from existing cellular signal boosters by boosting both the voice and data signals for all carriers without the need for an outside antenna. Now you can enjoy strong, reliable voice and data reception inside your home or apartment with the Sure Call EZ 4G.

Cellular signals sent from cell towers are received by the booster, amplified and then sent to your phone via the inside tabletop antenna.

This improves the strength and clarity of voice calls as well as providing faster data streaming. When your phone transmits, the signal is sent back through the cell booster to the cell tower. This makes staying connected easier than ever.

Installation is simple.

Find the area in your home with the strongest cell signal.

Mount the fan-like booster directly to the window with the adhesive strip or on the stand, whichever works best for your situation.

Connect the cable between the booster and the table-top antenna ensuring enough distance between the two devices to maximize your signal strength.

Connect the power adapter and plug it into the nearest outlet.

Sit back and enjoy your newly enhanced cellular signal with this innovative cell phone signal booster for homes and offices. You can stay connected with all of the important people in your life.

This SureCall booster supports 4G and 5G devices.

SureCall signal boosters are 5G compatible, which means they support both 4G and 5G devices. All SureCall's current vehicle and home boosters amplify any modulation (4G, 5G) that operates on the five most common up and down cellular frequencies bands. This makes SureCall current signal boosters compatible with 5G devices as carriers begin to transmit 5G signals over the existing frequency bands and towers.

Questions & Answers


Ask a Question
  • where is the serial number located on the sure call ez4g

    Turn over amplifier and you will see the model number and serial number of SureCall EZ 4G.

  • I received my order and set it up but can not get a signal anywhere in the house at all. Sometimes I can get a signal without the booster and I thought the booster would help but it does not. What am I doing wrong?

    It is possible that available signal strength is too weak to amplify with this type all-Carrier inside building donor antenna kit with up to +72dB Gain.

    Are you sure you placed the donor antenna in a spot with best signal in the house (preferably near a window)?  

    Please know that signal bars are not an accurate way to measure signal strength. They are finicky, seldom accurate, and do not update in realtime as you move the phone around.  

    To find the best spot with maximum signal strength, you must put your phone in field test mode, or make and receive calls and be able to hold that call to know for sure where signal is best. If you need to find best signal strength spot of all carriers, a signal meter may help.  

    If there's no good spot in the house with signal strength enough to make and hold a call, we highly recommend a kit that has exterior building antenna to catch better signals from outside to amplify. Here's the best suggestion:  

    If you have outside antenna installation limitations on your property (rented or not allowed by HOA), and you have some signal inside near a window, etc., (atleast -110dB 3G, -120dB 4G), then we believe that Cel-Fi DUO+ or PRO signal booster may help even more to get the required signal needed because it amplifies up to +100dB (vs ~ +72dB Gain provided by all all-carrier kits in the market). Like the kit you ordered, these do not require outside antenna installation.  

    Albeit, it amplifies signal of one Carrier network. Would that work for you? If yes, then please proceed to purchase that instead, and return your current kit for refund within 60 days of purchase. Please note the Cel-Fi kit price shown at link above does not include signal booster and installation service, but it can be installed fairly easily like SureCall EZ4G by using user guide and easy plug and play installation instructions that will be sent.  

    Please contact us if you need more help.

  • Will this work with Total Wireless phones?

    It should work with all carriers in North America, including Total-Wireless.

  • When you say the two units must be at least 30' apart, and they communicate through the cable, does that mean "as the crow flies" or does it mean the number of feet of cable between them? My 1600 sq. ft. story-and-a-half house would be difficult, the way it's laid out, to set the units up 30 feet apart for the areas that need a signal boost.

    As the crow flies, cable is not counted if it is not running in a straight line between antennas.

  • How long does it take to install this in a typical home?

    It takes only 15 minutes maximum to install it.

  • Does this have to be connected to the internet?

    No Internet needed - It works using a different concept whereby it takes very weak signals outside your house and amplifies them many fold to provide strong cellular reception inside.

  • Can multiple phones work on the same booster?

    Yes, multiple cell phones will receive the boost using this one same signal booster.

  • I am interested in an indoor cellphone booster (w/out outside antenna), but I noticed that your products only mention up to 4G LTE. What about 5G? Do your boosters work in 5G? I imagine they do, but I need confirmation. Thanks.

    This only covers 5G-E (5G Evolution) offered by carrier like AT&T Wireless.

    Consumer grade 5G signal booster is not required nor available anywhere, as of today, July 26th, 2020 because if you don't have 5G connectivity, your phone will automatically default back to 4G or LTE, and your 4G booster will help with connectivity if it is weak.

    Only commercial data applications may require 5G connectivity to work at their peak performance and therefore one commercial 5G signal booster is available at this time. It only boosts 5G, and does not boost 4G / LTE signals because it is intended only for niche 5G applications where latency matters.

    As far as smartphones, tablets, mobile hotspots, etc. are concerned, the speed on LTE / 4G is sufficient or satisfactory for all practical purposes.

    If you have a 3G phone, 3G booster will do. But if you have 4G / LTE / 5G phone, upgrade to 4G / LTE booster because that will prepare you for the next decade, and beyond. For more details, please read the following blog post:

    Old 3G Signal Boosters and New 4G / 5G Smart Phones: Why Upgrade?

  • I do see that both units require 30 feet distance between them, but I also saw that in another Question response you said that less than 30 ft. might still work depending on construction material. Can you elaborate more on what happens when the distance is less than 30 feet and how that has to do with building materials?

    Yes, oscillation or feedback can be mitigated in other ways than distance by having or placing obstruction between the two devices such as dense materials, RF blockers, and walls that may be dense with bricks or concrete.

    When the distance between window or exterior antenna and desktop or interior antenna is too little, and there's nothing blocking the possibility of feedback or oscillation between them, the booster will simply lower its output per built-in safety mechanism required by FCC regulations.

    If this happens, you will not realize the extent of in-building cellular signal broadcast coverage area as anticipated or needed around interior desktop antenna. In other words, it will not work as well as it is designed to work, providing as much indoor cell coverage area it is designed to provide, and you will not benefit from its maximum possible signal amplification feature.

  • Our cell interference is caused by a metal roof. What would be the minimum distance we could have between the two components that might still cover 1000 sq ft?

    Minimum thirty feet separation is required. Thank you.

  • We live in a Florida condo that has tinted windows. If we placed the EZ 4G booster on the stand near a window will the it receive the signal through the window? The reason why I ask is we used to have a ATT Microcell that worked well with our plain windows before we replaced them, then it didn’t work. Thank you for your feedback.

    Unfortunately, it is equally likely that it will work or it will not work. We don't know exact signal strength at the window post-tinting so we cannot speculate whether or not that would be enough for it to use for signal amplifier to amplify it to generate usable signal. We do offer 60 days money-back satisfaction guarantee if you wish to try it and find out whether it works for your situation.

  • Hello. Will this unit work through floors? 2-story small home.(Around 1,500 square ft.) 3 bars upstairs near window, only 1 bar downstairs. (Home is built into a hill.) Looking to place antenna in upstairs window, to boost downstairs signal. Can (To stream Netflix, Hulu, etc; using cellular 4G-No other internet options available at this property.) If this won't work, what units do you recommend for 2-story homes? Thank you!

    Yes, it should work if the 50 ft. cable would suffice for running it from upstairs to downstairs but Internet speed may not be as fast as you would like. The reason is that with access to 3 bars, this entry level booster may not be able to push signal all the way downstairs with excellent strength that your carrier and your cellular device is capable of running on. Therefore, to be sure you are happy with your purchase and to ensure you have full strength coverage throughout your home so you can enjoy fast mobile Internet speeds, we highly recommend a more powerful amplifier kit with an exterior antenna (installed outside window against the building wall or preferably on the roof). We do offer 60 days money back refund or exchange policy but it is still an inconvenience for you to go through that so we suggest any of the kits at the following link that are more powerful and have the most powerful Yagi antenna that can catch better signals than the window mount one within the EZ4G kit.

  • Can the 2 units be closer than 30’? If they can what is the difference between 30’ vs say 15’ on the decide?

    You can get the antennas closer together depending on the materials blocking the signal. If you have standard building materials on the outside wall of the house, you may be able to get the antennas closer together. We recommend a "soft install" where the antennas are loosely placed to determine if there is any potential problem.

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.
