  • Hi Peter,

    My wife and I will be visiting London UK this summer for a month. Can you please suggest which Pay as you go plan is better and also we want to do tethering as well which will enable to connect to our laptop.

  • Hi Ken

    I use my phone very little and want a new PAYG SIM

    I don’t want my credit to die after a month, I want it to carry, I’ve paid for it. Is there a PAYG option to do that?

    I do use the internet but I would say 95% wireless (at home or pubs, shops trains etc) so don’t need a whopping Gb allowance – again don’t want it to dissapear if I don’t use it.

    I might sent 2 or 3 texts a month max 6 so that is not a problem I guess

    Am I wishing for too much?

      • Thank for this Ken

        I will have a look at them

        Today (Sun) went in CPWarehouse and picked up a PAYG ID Sim

        It cost me £5 so I’m not going to get burnt too badly

        What attracted me to it was;

        I can top up for a fiver

        I think it may rollover (but that may be just for the bundles – not sure)

        And there isn’t an allowance split (Calls / Texts / Data)
        So I can use the full £5 on each individually or in a mix

        I’ll give it a go anyway, thanks for the advice


  • Hi Ken

    I have just acquired an I-pad mini and cant find a genuine PAYG sim data deal.

    So we have an emergency mobile on Giffgaff PAYG and it stays loaded until the money is used. With the tablet SIMS all providers appear to lock you into a pay your money ; convert to data and loose it at end of month type deal

    I only want to use the mobile network on the tablet in an emergency not on a regular basis .
    Any enlightened providers out there??

    Thanks Nigel

    • Hi Nigel,
      Many thanks for your comment. There are a bunch of mobile networks that will allow you to do this, but normally the cost will be fairly prohibitive. For instance, you could use giffgaff PAYG inside a tablet (no need to buy a goodybag or gigabag). The cost is 5p/MB so just 200MB of usage would deplete your £10 of credit.
      Probably the best solution I’m aware of is Three’s Data Reward SIM card. With Data Reward, you’ll get 200MB of free internet every month. After that, it’s just 1p/MB. If your usage never goes over 200MB per month, it’s possible you’ll never actually need to pay for any usage! If you go over the 200MB per month mark, your £10 top-up will give you 1GB of data. Once again, no need to convert your credit into a monthly bundle – just make sure to use the SIM card at least once every 6 months to keep it active.
      Hope this helps,
