How to Purchase a UK Prepaid Sim Card
If you’re used to buying SIM cards in the USA, you might be pleasantly surprised to know that you can actually buy a local SIM card in many arrival ports of the UK such as Heathrow or Gatwick Airport. However, while this might seem like a convenient option, there are few disadvantages of taking this approach.
The first and perhaps most obvious one is that if you’re coming to the UK after a long flight, you probably prefer to get as quickly as possible to wherever you’re staying, rather than dealing with shopping for prepaid UK Sim Card.
Secondly, a lot of the SIM cards sold at airports often are marked up meaning you are paying more than you should. And if you’re only travelling in the UK for a short period of time, you probably don’t want to waste your precious time going to the various telecom shops.
Finally, it’s undoubtedly more convenient to be able to connect to data as soon as you land in the UK either to be able to order a cheaper taxi through an app or simply to let your family back home know that you’ve arrived!
With a plethora of great UK prepaid sim cards for tourists available online, I personally suggest travellers pre-order one a few weeks before they’re due to leave, pop it into their phone and know that they’ll have data as soon as they land in the UK!
If you prefer to pick one up when landing in the UK and are prepared to pay an inflated price, then you can head to shops like WH Smith and Sim Local or alternatively lookout for vending machines that exist in some airports.
Will a UK Prepaid SIM Card Work in my Phone?
Before travelling overseas and purchasing a SIM card for UK travel, you want to make sure that your mobile phone is unlocked completely and will work with a different carrier to what you use back home.
If you have bought your mobile phone on a contract plan, you should call your provider at home and check to see if your phone can be unlocked. If you’re not under contract, your phone might still be locked but the provider should unlock it for free.
Be aware that your mobile phone provider might try to upsell you an expensive roaming package — this is undoubtedly the most costly option for travellers heading abroad. If, for whatever reason, you can’t get your phone unlocked, a cheaper option might be to purchase a mobile WiFi hotspot or an unlocked phone online.
Alternatively, you can always rely on public WiFI in cafes and your accommodation, however, this isn’t always ideal for a short trip! If you choose to go down this route, then make sure subscribe to a quality VPN such as ExpressVPN.

Hi Michael!
Do you know which would work best in the Scottish Highlands?
Thank you in advance and Happy New Year.
The Orange SIM is a good option if travelling in more rural areas.
I will be in UK only for 32 days and spend much my time in rural West Somerset, Wales, and Cornwall.
