Pay As You Go SIM CardWhether you’re a smartphone fanatic or someone who only uses their phone on an occasional basis, there are some great deals to be had when you order a free Pay As You Go SIM card in the UK.

The best Pay As You Go SIM cards offer super-low rates that can even rival Pay Monthly SIM cards in terms of value for money. To take advantage of the best offers currently available, simply order a free SIM card below and slot it inside your mobile phone. There are no credit checks required or upfront fees to pay. There’s also no need to set up a direct debit: simply top-up your SIM card when you need credit to pay for your usage.

In the table below, we’ve reviewed free SIM card offers from 20 of the UK’s most popular Pay As You Go networks. We’ve included mainstream providers as well as low-cost alternatives and specialist Pay As You Go mobile networks for calling another country. We’ve also compared the cost of each network to help you get the best value for money.

  1. Changing mobile network? If you’re keeping the same phone but changing to another network, it might be necessary to first unlock your handset. See our guides to unlocking an iPhone and unlocking a Samsung Galaxy handset.
  2. Coverage is identical on lots of mobile networks. Many mobile networks share the same coverage provider: you’ll get identical levels of coverage when using any of these networks. To give an example, VOXI uses coverage from Vodafone and giffgaff uses coverage from O2.
  3. Keeping your mobile number. If you’re changing mobile networks, it’s super easy to keep your current phone number. Once you’ve ordered your new Pay As You Go SIM card, get a PAC Code from your current network, either online or by text message. You can then pass this PAC Code on to your new mobile network and your phone number will be moved over on the next working day. For more information, see our guide to transferring your mobile phone number.

    I have a contract with BT for pay as you Go mobile. It cost £10 a month but I just pay £5 as I have BT Broadband. Am I getting free minutes and texts with this.

  • Avoid Vectone as they are taking orders (and your money) during the CoVid19 outbreak but not posting out Sim Cards – so you just seem to pay money out and receive nothing.

  • Shaun McDonald said:

    There’s also Zevvle who have tiered pay as you go data with option of either pay as you go calls and texts or unlimited. Very useful if you have spiky data usage from month to month as you don’t need to worry about the out of bundle charges or coping and changing which bundle you are on.

    A new mobile network, Zevvle, is launching and giving away 1 million shares. You can sign up at https://zevvle.com/signup?rid=DDC124 🚀
