Mobiles and phone companies?

Kimberley

How comes some mobiles do not work with some companies..I wanted to bid on a phone on ebay, but the seller says they have tried using the phones with different phone companies and it's only Vodaphone and 02 the phone doesn't work with.

As i'm on an 02 online PAYG tariff i obviously cannot bid on that phone..

Can anyone explain why some phones won't work with certain companies? :beer:

what phone is it ??

Kimberley

Nokia 6200

Browntoa

it's an american model phone

tri-band GSM/GPRS/EDGE 850/1800/1900 MHz

we use EGSM 900, GSM 1800,

so they are correct in what the say.....it's down to the Network Frequencies Orange and t-Mobile use 1800 the other 2 use 900 (which the phone does not support
