2.5G
An unofficial ‘upgrade’ to 2G, phones dubbed as being ‘2.5G’ are phones that use the same 2G technology, but come equipped with features that can be found on 3G phones, such as data transfer, GPRS radio and EDGE capabilities.
2G
2G is short for second-generation wireless mobile technology. Early mobile systems used analogue radio signals to transmit information – 2G phones use digital signals which require less battery power, allowing for more talk time and smaller batteries.
A clearer reception is also afforded thanks to the digital signal. Most of today's mobile phones, unless specified otherwise, are 2G.
3G
Short for third generation wireless mobile technology. 3G phones are more powerful than 2G and 2.5G phones, and are capable of high speed mobile internet access, allowing users to download audio files and video clips at near broadband speeds.
3G phones with a front-facing camera can also be used to make video calls to other 3G phones.
A-GPS
Short for Assisted GPS. Any phone with A-GPS will come loaded with navigational software optimised to acquire a satellite connection as quickly as possible.
Most mobile phones that come with a GPS receiver will come with A-GPS capabilities.
Anytime
In telephony terms, Anytime refers to a number of minutes a mobile contract will allow you to make at any time of day, before the traditional peak time of say 6pm on a weekday.
For example, a Pay Monthly contract may give you 1000 Anytime minutes to use each month; another might offer you a mixture of Anytime and Off-Peak minutes.
Bluetooth

Dual Band
A phone that has Dual Band coverage means that it will be able to make and receive calls both in the UK and the rest of Europe. Tri Band is similar, in that it allows for calls to be made in the US as well as Europe. Quad Band phones have global coverage.
Dual Band technology also means that a phone will have greater signal capacity. The majority of phones sold in the UK today will be Dual Band phones.
Dual Mode
A dual mode phone works between GSM and DECT.
EDGE
An acronym for Enhanced Data rates for GSM Evolution. Essentially this is an advance version of 2.5G technology, often thought of as '2.75G', allowing for faster connection to online services.
An EDGE-compatible phone allows you to download files and surf the mobile web.

GSM
This is an agreed standard global system for mobile communication. GSM phones all benefit from the clarity of digital call quality.
GSM phones operate on a variety of different bandwidths, which chiefly are GSM900 (operating on 900MHz), GSM1800 and 1900 (which operate on frequencies of 1800MHz and 19000MHz respectively).
In layman's terms, this is just a term used to differentiate the mobile networks from other voice call services such as Fixed Line and VoIP.
HSDPA
Short for High Speed Downlink Packet Access, an enhancement to 3G networks that allow users to download information and browse the web faster than GPRS or EDGE.
IMEI
International Mobile Equipment Identity: many new mobiles are issued with an IMEI number to counter mobile phone theft. If your phone is stolen, with the IMEI number the phone can be remotely disabled.
Dialling *#06# on your phone will see you able to access your phone's IMEI serial number.
Megapixel
A pixel - an amalgamation of 'picture element' - is a single point in a graphic image, and a Megapixel is equivalent to 1 million pixels.
The more Megapixels a digital camera on a mobile phone can capture in an image, the greater the quality and detail will be.
MicroSD Card / SD Card
SD is short for Secure Digital. A typical micro SD card is a portable memory card that can be used in a variety of devices, chiefly mobiles and PDAs.
They offer extra memory for handsets, so for example, a phone with an MP3 player or camera built in can make use of a micro SD card to store more music files or pictures.
SD cards come in various different sizes in terms of memory and physical size.
