It is expected that the paging industry will undergo several changes as new handheld devices and wireless services mature.
Doctors are a big market for pagers and messengers.
They need them incase their is an emergency in the hospital. Same goes for lawyers. My father works in the water and wastewater utility business and he carries a pager. If the home office in Valparaiso needs to get in contact with him or if someone else who works for the company needs to talk to him, they can page him. Basically the markets are endless.
