This article will help you determine what mobile frequency your Iphone is connected to.

Your Iphone will predominatly connect to one frequency in the location around your house.

Once you know this frequency, you can choose the best signal booster for you.

It will be one of these 5 frequencies

  • 800Mhz (Band 20)
  • 900Mhz (Band 8)
  • 1800Mhz (Band 3)
  • 2100Mhz (Band 1)
  • 2600Mhz (Band 7)

(Band numbers are just easy to read lables )

Lets find out which one it is!
