I've had this item for 6 months but isn't working the way I would like it. It could be that's not installed exactly the way it should be (re: not facing the right tower). It boosted my mobile stick perfectly, along with my cellphone signal BUT I was not able to use any data on my iPhone. The iPhone showed a full 5 bars but it was only good for making phones not surfing the web or using apps. Haven't used the booster for a month. I have to get up on the roof again and turn the booster in another direction and maybe it will work.
