A SIM card is the little chip that slots into your phone to enable your network of choice to provide the airtime and/or data allowance to be used by you on your phone.

Each network operator provides their own SIM cards for access to their network.

A pre-pay / pay-as-you-go (PAYG) SIM deal is simply a network SIM card that you pay for the airtime (and data) up-front. i.e. you’re not tied into any contract or commitment. You just pay for what you use.

So, simply grab one of our network SIM cards, along with one of our exceptional phone deals and start calling, texting, surfing, Instagramming, TikTok’ing etc!

There are 4 main networks in the UK that actually own the infrastructure – these are EE, O2, Vodafone and Three.

You can get an idea of the network’s signal strength in any area with Ofcom's Telecoms Coverage Checker.

All other smaller mobile providers (Also called Mobile Virtual Network Operators / MVNO’s) 'piggyback' off the main networks using their infrastructure.

MVNO’s such as GiffGaff and Lebara that we offer often provide the best deals for specific groups of customers – so check out their tariffs and see what’s best for you!
