How to Troubleshoot Signal on an SGH-T459 Gravity
A weak signal on your Samsung Gravity cell phone is often due to a blocked cell signal in your current location, which reduces your phone's ability to connect to the cell network and have clear phone reception. Alternatively, a poor signal can also be due to a lack of a nearby tower and causes your cell to switch to roaming mode to find a stable network. While the phone automatically connects to the nearest network, you can also manually connect to a specific network in your area. Roaming charges may apply when you are not within your cell's range and should be used sparingly to avoid a high phone bill.
