How To Choose A Right Signal Booster

The point is the frequency band number. ITU divides the available spectrum into many frequency bands, and then specifies different numbers for each frequency band. Operators in various countries choose different frequency bands to develop their own mobile phone network according to their own development needs. Therefore, if you know which frequency band number your cell phone operator uses to cover the mobile phone network, it is easy to choose a right signal booster, Because our signal booster is also designed according to the frequency band number of ITU, the frequency band number of the signal booster must be the same as that used by your operator,this can perfectly expand the coverage of cell phone signals in your home/office/apartment...etc.

How do you find the band number of your phone operator?With the progress of science and technology, ordinary people can easily view this information now,
