    Hi I need a 4g LTE signal booster duo as it is the only one that works with 700mhz frequencies (band 12). I have been trying to get one from t mobile for 2 years but they keep sending me the old signal booster even after they promise it works with my network which it doesn't. it costs me $20 in gas to return each one to the nearest t mobile store and its starting to get aggravating as tech support doesn't have the right information or resources to help me. the cell towers in my area only use 700mhz (band 12) so can one of the t mobile support specialest please send me a 4g LTE signal booster duo?
