Thank you for your feedback, at the moment this is just an idea to help raise awareness of devcoin as no mobile network accepts cryptocurrency for pay as you go phone credit. also not just young people, but many that use pay as you go do do because they do not have access to a banking account to set up a contract with a provider. any of these people can set up a crypto account and those that have one already would find phone credit a usefull product to spend there coin on . just saying you can now top up your phone on any uk network using devcoin should get some attention. even if the site accepts other currencys also. to prevent copycats doing a better job and stealing the idea i have made a demo website that charges no fees or commision. juas accepting tips if you like the service just to see if there is any interest in the idea. buying airtime at a discount later could make it profitable and then switch to only accepting devcoin when there are some funds in the account and it is a little more known . any help or feedback is much appreciated. jasont wwwcryptocredit.co.uk and cryptocreditphones.com
Concept looks good to me. You may want to look at coinpayments.net as it's a checkout system a few devcoin ecommerce sites are already using and may make like easier for you? Alternatively it might add control-loss and delay factors for you, so it's a balancing act. I hadn't really considered the bigger picture inclusion aspect you refer to - those that aren't banked etc.
One thought; how does someone without a bank account acquire crypto right now? Things are likely to change over time but if a significant proportion of the target group are the 'unbanked' or youngsters, not sure about the pragmatics of the potentially more vulnerable swapping cash for crypto in person. So - devcoin 'earners' aside - there might be a bit of an access loop to solve without becoming a money changer yourself (and you and I know just how flexible our gov is on cryptos to date). Maybe effecting a sort of swap - where somehow cash is switched for something else, then that something else is switched for crypto. I have to think about it more, I'm sure there are ways to do it if you don't already have one.
This is not to question the idea as I think it's a great one, just throwing thoughts at you.
I have a prepaid (pay as you go) phone, when I "buy credit" I go to the local shop/servo/deli and buy a slip of paper with a code on it, when I enter the code my account is topped up. (I also do this by Visa over the phone, but I am trying to address your target of people who don't have bank accounts)
Is it possible to do something similar?
For example, produce slips of paper with codes on them that can be entered by SMS or online, and puts a set amount into their wallet according to the cost of the slip of paper? (I guess QR codes might even make this easier) Maybe they could be sold by community groups in line with Devcoin community aims, and the community groups could receive a commission?
Devcoins were worth considerably less at that time as well, if that is to be considered. 
Thanx!
