The most signal strength I can get on my cell is 2 bars only and sometimes none at all. What should I do to improve this? I even added a signal booster that sticks inside the cell phone close to the antenna underneath the battery. By the way, my service provider is Rogers here in Canada.

Hi Raul,

Put a small piece of foil about 1" square behind the battery being careful not to let it touch a terminal.

It added two bars to my signal.
