What to Buy Once You Arrive in the City
A SIM Card for Cost Efficient Data and Voice
A prepaid British SIM card lets you use your smartphone, tablet and 3G laptop England
without clocking up a massive data roaming.
You can get SIM cards at Heathrow and other airports (from vending machines) but they are
expensive because of the convenience. They cost £10 at Heathrow and only around £1 in
London City.
Get into Central London, find a newsagent at any Underground Station - and they're bound
to have one that suits your requirements. There are nowadays many different SIM cards
available.
