Middle Rain

I recently change my mobile service provider due to expensive call and text abroad. My current mobile service provider offers much cheaper international text and call compare to my old one. However, the only problem is that my new provider has very low signal. Once you’re inside the home, you will get very poor signal so everytime I make a call I go outside to get a better signal. Hmm, I need a cell phone booster so I can get a full bar sigal even im inside our home.
