Anyone know a good deal on a cheap unlocked tri-band phone (pre paid or sim free)? Preferably Nokia / SonyEricsson. Don't want to spend more than £100 really.

do you want anything fancy or just the capability of tri or quad



Cheapest link being the prepaymania @£65.34

This is assuming tri band freqs are indeed covered by quad as I can't remember I'm assuming co's it seems logical but obviously if not then apologies for the stupid post.

lol I had very little sleep last night but taken from wiki on gsm frequencies

Today, most telephones support multiple bands as used in different countries to facilitate roaming. These are typically referred to as multi-band phones. Dual-band phones can cover GSM networks in pairs such as 900 and 1800 MHz frequencies (Europe, Asia, Australia and Brazil) or 850 and 1900 (North America and Brazil). European tri-band phones typically cover the 900, 1800 and 1900 bands giving good coverage in Europe and allowing limited use in North America, while North American tri-band phones utilize 850, 1800 and 1900 for widespread North American service but limited worldwide use. A new addition has been the quad-band phone, also known as a world phone, supporting all four major GSM bands, allowing for global use (excluding non-GSM countries such as Japan).

There are also multi-mode phones which can operate on GSM as well as on other mobile phone systems using other technical standards or proprietary technologies. Often these phones use multiple frequency bands as well. For example, one version of the Nokia 6340i GAIT phone sold in North America can operate on GSM-1900, GSM-850 and legacy TDMA-1900, TDMA-800, and AMPS-800, making it both multi-mode and multi-band.

Note that while the Nexus One, like many other devices on the market, may also become available in a UMTS I/II/IV or 2100/1900/850MHz combo,[5] it would still be considered tri-band UMTS, not quad-band, as the hardware is limited to supporting any 3 bands at one time. Further, as HSPA runs atop UMTS, it would not be considered a "mode" by strict definition.
