  • No SIM card mobiles

    Am I right in assuming the reason why some mobiles are sold as not needing a SIM card is because the buyer will be forced to pay the suppler of the phone for all calls and cannot choose anyone else?

    I was not aware of any (UK) mobiles which operate without a SIM card - SIM Free is somewhat different (you supply the phone, the operator supplies the SIM). Then again, Kindle 3G makes use of mobile networks without requiring a (user controlled) SIM (it may have an embedded one)

    If you really mean "operating without needing a SIM", please provide a link - my for no-sim phone fails dismally

      Visit http://www.carphonewarehouse.com/pho...o-g-4g-3rd-gen than click on NO SIM CARD and notice the price changes to almost 150. I take it to mean it has a SIM CARD but if you do not commit yourself to their probably expensive Monthly Contract you must pay 150 for the Phone.

        There is a standard called CDMA which doesn't use a SIM card, however I've only ever heard of it being used in North America (USA & Canada) - most of the rest of the world uses the GSM standards.

        Could just be that rather than a SIM slot there's an area of memory in the phone for the data that would normally be on the SIM though.

          Hi Gordon
          On my view of the page, it says "SIM Free", so buying the phone outright, then getting a SIM-only contract from any provider, rather than paying for the phone in instalments along with the SIM

          cruachan - that is presumably what kindles use, also the proposed "phone for help in an accident" functionality in cars?

            TBH I thought Kindles used SIMs, I had one that did, although that was an old model.

              Also known as buying the phone outright to use on any network you choose.

              IIRC my Kindle, one with the keyboard, has a SIM in it. Only noticed it when i had to replace the screen.
