    Which O2 mobile plan would be the cheapest for me being an OAP?

      Hi John,

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

      That would depend on your needs and preference, John. You can start using O2 mobile plan for as low as £10. However, that is for the basic service. You will incur the standard rates for calls, texts and data usage if you don’t have the minimum credit amount for their pay as you go bundle plans.

      On our page, the cheapest plan from O2 is £9.99 upfront. Please check our table and see which plan would best meet your needs and budget.

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

      Have a wonderful day!

    My elderly mother is in a care home and needs us to be able to phone her. What is the best SIM card option. I have already sourced a DORA handset for her.

      Hi Jeremy,

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

      Since your mother already has a handset, you might want to check our list of mobile plans. On that page, use our table to compare your options. Please take note of the feature column where you will know whether that particular plan is a SIM only plan or not. Once you find the right option, click on the “Go to site” green button or “More info” link.

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

      Have a wonderful day!
