which is the wireless carrier's identifier for a phone in the network. MINs and ESNs can be electronically checked to
help prevent fraud.
International Mobile Equipment Identifier (IMEI)
A unique 15-digit number that serves as the serial number of the GSM handset. The IMEI appears on the label located
on the back of the phone. The IMEI is automatically transmitted by the phone when the network asks for it. A network
operator might request the IMEI to determine if a device is in disrepair, stolen or to gather statistics on fraud or faults.
Roaming
The ability to use your cellular phone outside your usual service area – when traveling outside of the "home" service
area defined by a service provider. Higher per-minute rates are usually charged for calls made or received while
roaming. Long distance rates and a daily access fee may also apply.
SIM Card
A small printed circuit board that must be inserted in any GSM-based mobile phone when signing on as a subscriber. It
contains subscriber details, security information and memory for a personal directory of numbers. The card can be a
small plug-in type or sized as a credit-card but has the same functionality. The SIM card also stores data that identifies
the caller to the network service provider.
Soft Key
A key below the phone's main display panel that performs special functions.
Wireless Application Protocol (WAP)
An open standard for communication between handsets and the Internet. WAP is a wireless communications
environment for delivering web data to wireless terminals with minimal screen display. An initiative started by Unwired
Planet, Motorola, Nokia and Ericsson to develop a standard for wireless content delivery on the next generation of
mobile communicators. WAP strips all but graphics for display on small screens, such as mobile phones. A mini-
browser is an integral part of WAP enabled phones. WAP enabled phones first appeared in Europe at the end of 1999.
