UK SIM Cards: Get Connected Fast
Getting data on day one saves you money and hassle. If your phone supports eSIM, you can be online before you land. Prefer a physical SIM and a UK number straight away? Pick a pay-as-you-go provider and activate in minutes.

Lebara is our go-to starter SIM if you want a UK number on day one and cheap calls home. It uses the Vodafone network for strong coverage and offers simple 30-day plans you can set up online or in-store.
Why we chose it: reliable signal, clear pricing, and international minutes on many bundles—no contracts or credit checks. Start small, then tweak your plan month-to-month as you settle in.
Lycamobile
Popular with expats for low-cost international minutes to call home. Prepaid bundles, frequent promos, and wide availability in convenience stores. A solid pick if you’ll be making regular overseas calls.
