European Frequency List
Mobile phone signal boosters only amplify specific frequencies of RF signal which pertain to specific operators ( EE, Vodafone, O2, Three etc.) and mobile networks ((2G, 3G or 4G LTE) on those operators.Before you purchase a signal booster you need to make out which operator(s) you need to support, as well as which networks on these operators, as that determines which signal boosters you'll be able to use and which type of outside antenna you will need.
