Content: You will need a GSM phone that works on both the 900 MHz and 1800 MHz bands for use in the UK and/or Europe. Such phones are often described as "tri-band" or "quad-band". Check the specification of your phone in the product manual, or with your provider, or at GSM Arena by entering the model number in the 'quick search' box. Most "3G" handsets (900 MHz, 1800 MHz, and/or 2100 MHz) will work in most urban areas of UK and Europe, giving enhanced web and email access, as well as being usable for normal talk and text services. Do beware of roaming data charges, as internet access will be *very* expensive. What's GSM? GSM stands for Global System for Mobile Communication and is used across Europe and many other places around the world. But not in the US. GSM phones can be 'locked' to a network but they can be unlocked to allow you to use all the networks in the UK. You will also need a SIM card.
