Which one of the following statements referring to mobile Internet access is FALSE?
3G stands for Third
Generation and 4G
for Fourth
Generation.
A USB modem or Internet
dongle is a device with
which you can connect to
a 3G/4G network to
access the Internet.
A 3G/4G network is a high
speed data network used by
suppliers of mobile
cellphones for broadband
services and Internet
connection.
A USB modem looks
like a flash disk and
operates without a
SIM card.

Technically, the last statement is false. All cellular devices operate using a SIM card, they are essentially how a network service provider (I.e. AT&T, Verizon, et. al.) identify their devices and know what level of service to provide to the device when it sends/receives signals from their tower. Some USB wireless broadband devices do look like USB thumb drives, however, they will either contain an integrated SIM card or have a spot for a replaceable SIM card.
