A handphone, short for “handheld phone,” cell phone or cell, sometimes shortened to just handphone, hand or cell phone, maybe a small portable phone that can make and receive telephone calls over a cellular signal line while the user is traveling within a public telephone service area while not using an attached handset to make telephone calls. The term “handphone” generally refers to any mobile handphone equipped with voice dialing capability that is capable of connecting directly to a cellular service provider. Today’s hand phones generally come in two varieties: digital and analog. Digital handsets are equipped with caller identification (CDR), or the digital signature of a specific telephone number, which allows the phone to be recognized by a caller ID. Analog handsets usually do not include any signature feature. Modern analog handsets usually incorporate the CDR feature as well as the latest technology such as GSM, CDMA, GPRS, EDGE, and WLL.
