Listing is for 25 TOTAL Generation X Antenna cell boosters.
These are the NEW & IMPROVED Generation X ones! Each retail for $19.99. Each comes factory sealed! Cell Boosters can be put inside your phone, on the back of your phone, or inside your cell phone case
Please note: If your cell phone does not have a spot for inside the phone you can always stick the cell booster on the back of the phone or even inside your cell phone case itself (iPhone,etc.) As long as it will be near the phone it will help with your signal. iPhones and other smart phones you will not physically see the signal bars raise to know that it is working. That is because the signal bars are controlled internally with your software of your cell phone. This just helps add to your antenna range.
About expectations of ALL CELL BOOSTERS sold: Please understand that all cell phones are different, along with the many phone companies. These boosters are designed to enhance the cell phone reception that you get with your phone. It really acts that the antenna is much larger. If you are having extreme cell phone issues there is nothing sold on line that can be better than changing to a new phone or switch to a new carrier. So to think this will make a cell phone work 100% perfect at all times is not possible ( otherwise every phone on earth would have these inside the phone :) We just like to keep it real and not try to mislead our customers. These are designed to just help your signal more and will do a great job at that. There is a reason why these have been around for over 10 years because they do work good. For the small investment on them you can't go wrong.
