What is the moble network when u can call all the networks?

0800-reverse on UK mobile networks

• http://www.reversecorp.co.uk/faqs.htm - are there any mobile networks that support this on pre-paid ("pay as you go") tariffs? This seems to be a bit of an oddity. Virgin mobile say they do not support it; O2 also say that - yet I have used an O2 phone with no credit left to call a landline via 0800-reverse. http://www.reversecorp.co.uk/faqs.htm#how say "0800 Reverse is the new way to call reverse charge. Simply dial the numbers that spell 0800 Reverse from any phone, anywhere in the UK. Just hit the seven once, the three once and so on. That’s 0800 7-3-8-3-7-7-3. You will then be asked to dial the number of the person you wish to call and will also be asked your name – it’s that simple. It’s so easy to remember and you’ll never need to carry loose change to make a call, or if a payphone won’t accept your coins*. *Some mobile networks, hotels, and some payphones may charge the caller for a call to 0800 Reverse." Are there any UK telecoms specialists here that know with some certainty that a network supports this? Thanks in advance!

• Answer:

  Just so that I'm being clear: I want to find a service that allows people with no credit left on their UK pay as you go mobiles to call a UK landline at no cost to themselves (I realise the service is charged to the accepting party). 0800-reverse misleadingly use phrases like "Use 0800 Reverse from any phone in the UK to call virtually anywhere in the UK." & "0800 REVERSE Charge calls can be made from ordinary lines, payphone lines and mobile phones in the United Kingdom. They can be made to ordinary lines in the United Kingdom, but not to mobile, pager, Freefone, number translation service numbers (such as 0800, 0845 and 0870), premium rate numbers (such as 0900, 0907 and 0911) or payphone numbers. " I just want to know which mobile operator in the UK actually does support this service. Ta.
