      Hi Dr nat,

      Thanks for getting in touch with finder. I hope all is well with you. :)

      Yes, you can use your mobile plan in London and Florida, USA. Upon checking, you can take advantage of Three Mobile’s Data Passport. You can pay £5 a day and you will enjoy unlimited unrestricted data. Moreover, you can also use Three Mobile’s Go Roam which allows you to use your SIM with no extra cost as long as you use it in one of the countries covered by the promo.

      I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.

      Have a wonderful day!

    Is there a Company that covers my phone for largely emergency use. I like the comfort of having a mobile I know I can use when travelling on a Motorway and not much else, maybe the very occasional short call. I dislike the one’s that you pay for per month and if you don’t use it then it’s gone! Perhaps should add I am 71 and find myself driving less and less too.

      Hi Patricia,

      Thanks for getting in touch with finder. I hope all is well with you. :)

      Generally, if you will subscribe to a prepaid promo, the expiration of your credit will shorten. However, if you want to keep it longer than usual, you may want to top up your phone with regular load or credit. This way, your credit will stay with you longer.

      Unfortunately, it is difficult to find a company that allows you to carry credit without any expiration. So, you just have to choose between topping up with a regular load, which have a longer expiration date or simply subscribing to a prepaid promo, which comes with more perks though it expires faster.

      I hope this helps. Should you have further questions, please don’t hesitate to reach us out again.

      Have a wonderful day!

    I am journeying to the UK for approximately 12 months and would like to know what you would suggest for a sim card. I won’t be making a lot of calls, so it is mainly data for photos etc.

      Hi Jeffrey,

      Thanks for visiting finder!

      Depending on how heavy are you on calls and data, you may compare Three Mobile’s roaming features such as Feel At Home and Data Passport which allow you to use your plan overseas. Alternatively, you may also check local sims in Indonesia and see if their rates are cheaper than your provider’s roaming charges.

      Feel free to message us if you have other questions.

      Best regards,
