[wolfyy59]

excuse me am newbie about radio signals , can i intercept sms messages on 3g 4glte? or it work only on 2g? because when i make a call when i see the frequency its 900mhz same as receiving smss so i thought that i can intercept my phone messages outside on 4g lte and 3g because its delivered only on 900mhz thanks
