Wireless technology allows a user to have a phone conversation in the middle of a supermarket and or while driving on the highway. Wireless networks have limits and moving to the edge of coverage area can mean losing the signal. Sometimes, wireless signals are weak and abruptly end conversations. Improving wireless reception isn’t always possible, but sometimes a few minutes can boost the signal and stop the aggravation that comes with a low signal.
Charge the battery and make sure it stays charged. A low battery can make reception worse.
Hold the phone upright rather than perpendicular. Cell phone antennas are made to be used in the upright position and work best when held straight.
