Tourists do not need contract tariffs, so in the future we will only talk about Pay-as-you-go tariffs or “30 days” tariffs, that is, “contracts” valid for only 30 days. To buy such SIM cards in the UK, no documents are required. Before buying a card, find out the size or type of SIM card in your device.

Cellular connection for voice calls from England If you cambodia cell phone number list don't need mobile internet in London, and you only need a SIM card for voice calls abroad from England (for example, to Russia or Ukraine) or within England, then buy a Lebara Mobile card and don't worry. The card is often free, provided you buy £5 worth of credit, although I have seen cases where dodgy shopkeepers wanted between a pound and a fiver for the card itself.
You can safely ignore them, unless you have time to find another shop. There have been cases of people buying a Lebar SIM card online for a hotel address.
