FAQ
1. What do I need to know before ordering a signal booster?
Before ordering, you need to know your network operator frequency. Every network operator has its own technology and frequency. The signal booster can only work well when it is suitable for your network frequency, otherwise it would not boost any signal.
2. How do a find my network frequency?
If you don't know your band, you can query through these simple operations (iPhone: Dial *3001#12345#* -> Serving Cell Info -> LTE -> Freq Band Indicator, Android Phone: Download and install the app 'LTE discovery' -> SIGNALS -> EARFCN )
3. My outside signal only has 1 bar, the booster can bring me signal?
Yes, it can. According to this situation, you need a higher dB gain booster (70dB gain)+ a higher dbi outdoor PANEL antenna+ a higher dbi indoor WHIP antenna.
4. Mobile phone has full signal with booster, but can not make call or send message?
Maybe it is the signal input and signal output interfere with each other. You need make sure: There is separate wall between indoor and outdoor antenna, so that the two antenna signal do not interfere with each other. Please try to change the direction of outdoor antenna.
