Whats 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.
Whats a SIM card?
SIM stands for Subscriber Identity Module . This small piece of plastic (about the size of a postage stamp) has a chip which holds all the information about your cell phone number, your contacts, security access details, etc. You can move your SIM to a new cell phone so you can keep all your important numbers and dont have to change your number when you get a new phone.
Cell Phone Options for US Visitors
- Firstly, you should contact your phone network provider and ask them if you can use your current phone in Europe. They may have options for you as a current customer.
- Consider switching carriers, if you are not locked into a contract. AT&T appear to be offering GSM technology so speak to them about your requirements. Find your local AT&T store.
- If you travel regularly, buy a GSM handset for as little as $49 (2007 prices). If your trip is for more than a few weeks it can be cheaper than renting. Check out the options at:
- You will still need a SIM card for these phones which can get from the companies above (and many others) or pick one up when you arrive in London. Find out more about Pay As You Go cell phones in London.
