U.K. cell network providers such as Three, Vodafone and EE allow customers to purchase pay-as-you-go SIM cards to use while traveling in the United Kingdom. Customers pay a nominal fee for the SIM cards and top them up when needed.
People visiting the United Kingdom from abroad can use pay-as-you-go SIM cards if their phones are unlocked. Three's SIM-only deals include bundles. One deal available in 2015 included 500 megabytes of data, 100 minutes and 3000 texts for £10, lasting for 30 days. EE's pay-as-you-go deals have animal themes; one deal featured in 2015 included free calls, texts and photo messages. Vodafone's deals offer value 4G Internet and reward points, which users can claim back on future offers.
Visitors to the United Kingdom who need to purchase a SIM card can do so in the network's store, or they can order one online if they have a temporary U.K. address. Some networks, such as Vodafone, let their customers register for an online account that lets them check their package usage. Networks may also prompt customers to renew their package before the end of each month. Three allows its prospective customers to check online to see whether their phones are suitable for the company's SIM cards.
