There are some ways to check the frequency: (Frequency doesn`t match, the signal booster can`t works.)
1. Turn on the network (2G/3G/4G) you want to amplify and go to outdoors of your house: A: If you use Samsung phone .Holding the phone to the outside. Dial: *#0011# ¡æServiceMode¡æ B: If you use iPhone .Holding the phone to the outside.Dial: *3001#12345#* ¡æ click into :Serving Cell info 2.Install an app: Network cell info Lite, and show the screenshot to us.

How cell signal booster works ?
1.The outdoor antenna captures signal from the signal tower
2.The outdoor antenna transfers the signal to the cell booster via the Coaxial cable
3.The booster amplifies cell signal and sends it to the Indoor antenna
4.The Indoor antenna rebroadcasts the signal insides to all mobile devices
5.The Booster amplifies outgoing cell signal back to the signal tower
Perfect for 1 - 2 room or small offices: Say goodbye to dropped calls in your home.

3. led light indicates the state of the signal.
4. if can meet 800 850 900 1800 2100 2600 frequency band , it can support different oprators.
5. easy to install. This signal amplifier kit includes everything you need.
Installation steps:
1. Fix the reception of the roof outdoor antenna or the high place and the turn signal point.
2. Connect the external antenna to repeater machine `` BTS `` port via cable.
3. Connect indoor antenna to repeater `` MOBILE `` port.
4. AC plug power cord into the power source and finished.
5. TIP: An outdoor antenna should be "isolated" from the internal antenna, that is, it must be constructiveobstacles (walls, partitions, etc.) between the antennas.
Note
:when outdoor antenna and indoor antenna are separated not enough, then it will be self-oscillation. yourphone will not get any signal.
