Frequently Asked Questions

1. What components does the cell phone signal booster kit contain? How it works? Can I use a signal booster if my phone does not receive signals outside?

Answer: The signal amplifier kit includes signal amplifier body, outdoor antenna, indoor antenna and other main components. The amplifier must be used with an antenna to work.

B. The external antenna receives the signal from the cell phone and sends it to the signal booster for amplification. Using indoor antennas, the amplified signal can cover the area required by the user, thus improving call quality and preventing disconnection. It is also suitable for surfing the Internet and transferring data with mobile phones, tablets or computers.

C. The amplifier will only amplify the signal, but will not generate the cellphone signal, that is, if your cellphone does not receive the signal outside, the amplifier will not work. not.

2. What should I know before buying a cell phone signal booster?

Before shopping, you should know the frequency range used by mobile operators. Different cellular network operators may use different technologies and frequencies. The range of frequencies in which the mobile phone operates must include the range of frequencies used by the mobile operator. This makes the amplifier work, otherwise the amplifier will not work.

3. I don't know the frequency range used by the mobile operator, what should I do?

Please don't buy it at first, please browse the frequency range on the frequency website.

You can also contact our customer service and write an email, which should list the following three points, so that we can help you choose the right product.

(1) The name of the mobile operator you use, in which country do you use it?

(2) Which 2G / 3G / 4G network do you want to use?

(3) Call or surf the Internet?

4. What if I buy the wrong signal amplifier frequency?

To reduce loss, please contact customer service. We provide the right solution.

5. After installing the signal booster, why is the phone signal not boosted?

There are two reasons:

(1) The frequency of the signal booster you purchased does not include the frequency of the mobile network operator you are using.

(2) The main body and components of the amplifier are damaged.

6. The cell phone signal is very strong, but I cannot make calls or send SMS.

There may be interference in the amplifier input and output signals. Please confirm the installation. The distance between the indoor antenna and the outdoor antenna should exceed 10 meters. It is better to have a wall between the outdoor antenna and the indoor antenna. This ensures that no interference occurs when receiving the signal. You can also try changing the direction of the outdoor antenna.

7. What should I do if I receive the package and find that the item is missing?

Please contact customer service first, do not post negative feedback, and do not initiate return requests or disputes in individual cases.

8. Why is the outdoor signal good but the indoor signal poor?

The reason is that a large amount of steel and concrete is used in the building, and the insulation board or aluminum foil on the roof is glued to the exterior wall. A large amount of metal used in buildings or some metal structures in buildings can cause cell phone signals to be completely blocked. In this case, a signal amplifier can also be used.
