Free Pay As You Go SIM Cards – Listed, Reviewed and Networks Compared
November 24th, 2011
We compare free Pay As You Go SIM card offerings from 15 of the UK’s mobile operators.

Whether you’re a very occasional mobile phone user or a heavy phone user who’ll use hundreds of minutes each month, great deals can be had on Pay As You Go if you shop around. As Pay As You Go tariffs don’t lock you in for 24 months, competition is fierce in the Pay As You Go market as companies are constantly competing for customers.
Pay As You Go tariffs make it easy to control the amount you spend: once you’ve run out of credit you’ll need to top up and because they’re not a credit product no credit check is required. The downside of Pay As You Go compared to Pay Monthly is that you won’t get the “free” or subsidised phones which come with a traditional mobile phone contract.
We think Pay As You Go is great if you’ve already got your own mobile phone which you’re happy to keep. By inserting a free Pay As You Go SIM card into your phone, you can take advantage of some great deals and cheap calls and texts. In this guide, we’ve got a comprehensive list of free SIM card offers from 15 of the top mobile operators. These include the big name networks, low-cost mobile operators and specialist networks for international calling. Several of the SIM card include free credit once you’ve activated them.
The most choice amongst “Ken’s Tech Tips” readers is giffgaff. They offer 250 minutes, unlimited texts and unlimited internet on a £10/month goodybag. Outside of a goodybag bundle, calls cost 10p/minute, texts cost 6p each and accessing the web costs 20p/day. Calls, texts and video calls to other giffgaff members are free. You can get a free SIM card from giffgaff here or read our in-depth giffgaff review.
- Keeping your phone: Remember that your mobile phone must be unlocked for you to switch network.
- Keeping your number: If you wish to keep your phone number, you will need to request a PAC code from your current network and provide this to your new network. Our PAC Code Finder will walk you through this process.
- Checking coverage: To find out what coverage is like where you live on a given network, see our guide to checking coverage in your local area.
- Check out Pay Monthly too. If you make a lot of calls or have a smartphone, you may get a better deal on a SIM Only contract. See our guide to the best value SIM-only smartphone tariffs.

Ken
are those information updated. like 3 pay as you go offers. would it last for 90 days with those amazing credits
Thank you Ken for this review.
I found looking at some of the indvidual service provider websites quite confusing and were pushing pseudo-contracts a bit too hard.
As a light user I chose Asda because of their clear and concise tarrif details (plus no hidden charges) and the ability to add cheap talk minutes as and when I need them.
Other points I like about Asda are that they use Vodafone for their network and the call centre staff are really pleasant and super helpful.
