I would appreciate any help about calling mobiles.

[#1]

Most months i spend anything between £5 - £8 on mobile calls. I did read somewhere you can add mobiles for £3. What does that include. Any help would be appreciated. Many thanks .

UK Mobiles 100 inclusive minutes available for £3 per month (for packages taken on or after 8th May 2013)

Despite what it says there I don't think it is available as a pure addon
