    Questions & Answers


    Ask a Question
    • Will this work in canada?

      Yes, it will work in Canada for all carriers such as Rogers, Telus, Bell and their MVNOs or subsidiaries such as Fido, Koodo, and Virgin Mobile.

    • how do i find which direction to point the out door antenna.

      Since exterior antenna is omnidirectional, it does not have to be pointed towards any particular direction. It does have to be installed vertically so it can absorb signals from 360 degress (all directions).

    • Will this work in Ecuador?

      Yes, this cell phone signal booster will work in Ecuador. It is compatible with Claro's 850 Mhz spectrum and possibly Movistar's 2100 MHz 3G or CNT Mobile's 1700 MHz 4G LTE. However, it not work in UK.


      Yes, this cell phone signal booster covers all bands and boosts mobile reception of all wireless networks of all service providers in USA & Canada, including Consumer Cellular network in that zip code.

    • This system work with Videotron?

      Yes, absolutely - This wireless signal booster kit will work with Videotron network in Canada. The Vidéotron Mobile network uses Advanced Wireless Services (AWS) spectrum using LTE on the 1700 MHz and 2100 MHz frequencies which are covered by this mobile signal booster system.

    • Will this work for Freedom wireless bands in Canada?

      Yes, this mobile signal amplifier kit will work with Freedom Mobile network which covers 700 MHz to 2500 MHz frequencies. In fact, it works with all carrier networks in USA and Canada.

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

      It takes only 15 minutes maximum to install it.

    • Why must the carrier be notified?

      Just to clarify, when we say carrier must be notified, it does not mean that you literally need to call the carrier to tell them you're going to use a signal booster. It is much easier than that because you merely submit a booster registration online form at their website providing your cell phone number and address where it will be used.

      To precisely answer your question, providing such information can help your carrier contact you to request you to turn it off in a rare event it does not work properly and begins to damage their wireless network.

      Such occurrences are rare because all our USA signal boosters are FCC certified and Canadian signal boosters are IC / ISED approved. Such approvals or certifications ensure that they work properly without damaging the cellular networks for the most part unless they have a manufacturers defect or they have got damaged due to severe impact or have come in contact with water causing water damage.

      However, unlike the past when such regulations we not in place, there're hardly any such instances now. In the past, such instances were more frequent because some signal boosters would not power down or reduce amplification when oscillation was detected causing runaway oscillation causing damage to cell phone towers and network owned by carriers. 

      That is the reason why mobile carriers collaborated with cell phone signal booster manufacturers and federal regulators to require certification and approval process to ensure signal boosters worked properly in proper manner to prevent damage to the network. Within those regulations, it also required cell subscribers that used them to notify their respective carrier to ensure that if and when that carrier detected a runaway oscillation occurrence, they can contact that signal booster user to request them to power it off and have it fixed or replaced to mitigate damage to the wireless network or stop interference that may otherwise prevent other cell phone subscribers using same cell tower from using their cellular service.

    • How far can this boost signals? 20+ km?

      The SureCall Flare signal booster can cover an average of 1 to 2 rooms. If you're talking about how far can you receive a signal, it is "theoretically" around 30 miles.

      Realistically though, if you're talking about how far the booster can transmit back to the tower, it could do 20+ km if you're using a Yagi antenna for outside (here's the same kit with Yagi:, and there are few obstructions along line of sight. 

      However, please note that you still need a decent amount of strength such as below -100 dBm (readings from phone) at the spot where you would mount your exterior antenna for the signal booster to improve reception indoors.
