Do those signal booster stickers for cell phones really work?

It looks like a scam to me but was just wondering if anyone has one and if it really works or not.

Answers:

No they really don%26#39;t do anything. Save your $10. NO they do NOT work. If they happen to pull a little more signal, they are essentially frying your brain and your battery. I worked at a cell phone company and we did not suggest them to ANYONE. On top of all that, they void your warranty on your phone as well. the only time they will help you is when you are using an analog network. It seems to. I have on that came with my order from EBAY and I%26#39;ve never lost more than two bars of coverage. no

if you want better reception get a quad band phone. (world phone)
