So you bought and you see:
You probably wondering what that can be used for? Here’s what I know and from what I found out. That little can be used as an external Antenna. You could also use this to boost your signal and be able to use this for places that might not be getting a better speed upward and downward bandwidth. You see it all depends on where the Cell Towers are. Although this will likely help those who are either 1 to Almost Zero signal, it will not help those who are outside of the network. It might help and it might not, it depends on the location your at and the closest coverage area. If your on the edge of the coverage area and you buy this antenna it Should boost your signal and get you a better speed. I will not say it will help but in theory it could help. If you want to find out the other post that I have done on this subject please check my Cricket tag for more information. Although it varies on person to person, and region to region this is going to be a variable that will always remain in the grey. Only way to find out is to try it.
