It's rarely the phone. It's the carrier, their towers and your location.
Try other carriers. Here, Sprint is the worst, ATT and Tmobile are great. But move 50 miles and that will change.
If you only get one bar around the outside of the home, those signal boosters will not help. Try other carriers.
I live in a very rural area. The cell phone signal is usually just one bar on my current phone. I have a Samsung 528. It is over 5years old. I am looking to purchase a new phone that doesn't keep loosing signal out here. Can you help me?
