Unlike mobile phones, you have to plug in electricity to charge your pager. The mobile phones need to be charged more than 3 times a day. Sometimes even two or three times. In case of a power cut, a mobile phone’s battery runs down and dies, and you remain helpless in case of an emergency. You can replace another battery when you are using the pager and the battery runs down. The pagers usually require an AA battery which can last for a longer time period than your phone battery.
