-If the wireless network is congested or down in your area, find an available Wi-Fi connection and switch to it on your phone.
-If you need to call out but the network is busy, wait several seconds before trying your call again. It allows time for the lines to clear.
In addition to the above tips, NBC’s Bob Sullivan also recommends the following cell phone tips:
-Turn your cell phone on airplane mode.
-Turn off your cell so your Wi-Fi detector is not searching for networks when they are not needed.
Providers also created portable cell sites in the mid-Atlantic and Northeast regions of the U.S. in case standard towers are damaged during the storm.
