The best way to avoid high roaming costs when you travel to the UK is to buy a local SIM card when you arrive at Heathrow. This is the best way to stay in touch and it doesn't have to cost much. Save time on arrival by pre-ordering your SIM card online for collection at the airport. You'll collect your SIM from the WeKnow welcome desks located in every arrivals terminal at Heathrow and our friendly staff will set up and activate your SIM card for you to make sure you're connected from the get go.


Our SIM plans are valid for 30-days, which is long enough for most travellers, however, if you need to use your SIM for longer than a month you can top it up after your initial plan ends for £15 less than the original plan selling price. So, if you purchase a £30.00 SIM card, topping up for the next 30-days will only cost you £15.00.


For complete flexibility, our Three Unlimited SIM card offers unlimited calls, texts and data. This option is great for those wishing to use heavy data for maps, social media, music streaming and data-based messaging services such as WhatsApp. For those wishing to call internationally, O2 plans offer the best international rates. Get the best deals from the most popular UK Networks including Vodafone and EE.
