    Find the best SIM Only deal for you

    SIM Only Finder compares sim only deals and tariffs from the UK’s leading mobile networks and Virtual Networks. These include Three, O2, Vodafone, iD Mobile, Smarty, VOXI, 1pMobile, Lebara Mobile, Lycamobile, Asda Mobile and Spusu.

    Use the filters above to search for your ideal SIM Only Deal, you can search by minutes, texts, data, cost, contract length and network.

    We have hundreds of available deals with low cost plans and those with unlimited all you can eat data.

    What is a SIM Only deal?

    A SIM Only deal is great if you already have an existing mobile phone but you are looking for a better deal!

    Similar to a mobile phone contract a SIM Only deal gives you an inclusive amount of data, minutes and text messages but at a much cheaper rate! This is because the network will not be subsidising the cost of a mobile phone.

    You can also transfer your current mobile number to your new network provider.

    Will there be any downtime when I switch my number to another network?

    There is usually minimal downtime when switching your mobile number from one network to another. The process usually takes one working day, and the downtime is usually only a few minutes at the end of this time.

    You can find more about switching your mobile number by reading our handy guide.

    What can I do with my old SIM?

    Once your old SIM card has been deactivated, you can destroy it as there is no value in a SIM card.

    Be sure to cut the SIM card in half like you would like an old bank card. When cutting through the SIM card, be sure to cut through the gold foil. This will ensure that it is absolutely corrupted and no one can get access to the data on it. Then just put the pieces in the bin.

    When does my SIM Only contract start?

    Your new SIM only contract will start as soon as you receive the SIM card, or E-SIM if you have opted for one.

    You can choose to use it straight away or wait until your number has been transferred over to start using your new SIM card.
