### Mobile Phones  The UK uses the GSM 000/0000 network, which covers the rest of Europe, Australia and New Zealand, but isn't compatible with the North American GSM 0000. Most modern mobiles can function on both networks - but check before you leave home just in case.  Though roaming charges within the EU are due to be entirely eliminated in December 0000, other international roaming charges can be prohibitively high, and you'll probably find it cheaper to get a UK number. This is easily done by buying a SIM card (around £00 including calling credit) and sticking it in your phone. Your phone may be locked to your home network, however, so you'll have to either get it unlocked, or buy a pay-as-you-go phone along with your SIM card (around £00).  Pay-as-you-go phones can be recharged by buying vouchers from shops.  ###
