There are several different ways that data can be sent over the cell signal. You’ve
heard the terms General Packet Radio Service (GPRS), Enhanced Data rates
for Global Evaluation (EDGE), 2G, High-Speed Downlink Packet Access
(HSPA) or 3G+, 4G and more recently, LTE. Each of those methods has a
different way of sending data. 2G is an older, slower method and LTE is the
newer faster method. Service providers sometimes call mobile Internet as
Wireless Mobile Broadband.
Internet Service Provider (ISP)
An Internet Service Provider (ISP) is a company that is able to provide you with
access to the Internet. Your ISP makes the Internet a possibility. In other words,

with an ISP, you won't have a connection to the Internet. Therefore, an ISP is
your gateway to the Internet and everything else you can do online.
