Free SIM cards FAQs
How to order your free SIM?
We’ve made this really simple. Simply click through on the networks above and after you have entered your postal details it’s just a case of waiting for your new SIM Cards to be delivered.
We’ve now also added the eSIM option to our pages. If you want or need one of the many eSIMs available simply choose your network above and follow the same ordering process as you would to order an original card. These can be up and running in just a few minutes after ordering.
How long will it take for my new SIM to arrive?
In most cases around 2 days. This can sometimes be the next day. Delivery is normally by Royal Mail 1st Class post but on occasions some networks use a courier. Either way delivery is always free as is the SIM card that is being sent!
Why are they free – what’s the catch?
The catch? None at all. The reason why many of the UK mobile networks give away free SIM cards is that they want you as a customer! As a marketing tool it’s a great value way of them gaining customers and the great thing is it means you don’t have to pay for the SIM card! Everyone wins which is a nice change!
Ordering limits
Each network has it’s limits on how many Free SIM Cards you can order. This tends to be limited to a set amount per household over a set period of time. You are of course welcome to order free SIMs from all the networks listed on our site. In fact this is a good idea as you never know when a SIM Card might come in handy!
What to do when your SIM Card arrives?
Once arrived, you simply need to insert your free SIM Card into any unlocked or same network handset and that is it. You can then start enjoying the savings of a better value mobile price plan all with no contracts, catches or expensive line rental costs.
I want to keep my current number

Simply text the word ‘PAC’ to 65075 from the number you want to transfer and your current network will text you back within 1 minute with your PAC code! This message wont cost you anything and works with all UK mobile networks!
