TelephoneIM.com provides discount calling service for Mobile World SIM card users in the United Kingdom. Mobile World provides excellent rates for calling internationally, but calling UK fixed lines costs 15p/min. By first dialing an access number in the USA at 5p/min, Mobile World users may then call back to UK fixed lines for only 2p/min more. The total cost is then only 7p/min, a savings of over 50%! Calls to UK Mobile phones and 08 numbers are 7.5p/min (for a total of 12.5p/min).
