How to Get Better Reception With an iPhone
The iPhone uses an antenna to send and receive phone calls, and relies on the cellular network for the signal. Getting better reception on the iPhone involves boosting the ability of the antenna to receive the cellular network’s signal. This can be done both by using special devices that will improve the antenna's ability to work, as well as having the iPhone adapt itself to the best cellular signal available at a given time. Improving the cellular reception of the iPhone does not damage the cell phone or cause problems with the Apple warranty.
Install a cell phone amplifier in your home or other location. The cell phone amplifier's antenna will boost the cellular network's signal to give you better reception when using your iPhone.
Put the iPhone in a "booster" case which passively increases the cell phone's internal antenna's ability to receive the cellular network's signal.
Keep your iPhone as fully charged as possible--the more power the iPhone has, the stronger its transmission ability.
Turn off the 3G network on the iPhone from the "Network" screen inside the "Settings" app. Using the 2G network can improve the iPhone's reception since there are many areas where the 3G network's strength is low.
Signal strength issues can be resolved by resetting the iPhone. Reset the iPhone by holding down the "Sleep/Wake" button and the "Home" button until the "Reset" slider appears. Swipe the slider to shut down the phone. Press and hold the "Sleep/Wake" button until the Apple logo appears.
Tips & Warnings
- The cell phone amplifier needs to be of the "repeater" type in order to work effectively with the iPhone.
- A hard case/battery pack attached to the iPhone might cut down on its effectiveness at receiving cell phone calls.
