As the first scheme of its kind in the UK, you'll get money for converting your friends on to 3's Pay As You Go service, and to help your cause – the SIM cards are free.
For every friend who picks up a 3 SIM and tops up, you'll get £5 cash paid in to your Paypal account, and your mate will also get an extra £2 credit on their PAYG balance as well.
If that hasn't sold it to them, here's the clincher. Anyone using the 3 SIM in a 3G phone will benefit from free texts, internet and 3-to-3 calls for 90 days after their top up, even if they run out of credit, not to mention free Skype-to-Skype calls and IMing forever, whether they have credit or not. Don't say you never get something for nothing.
Once you register as a "3 Free Agent", you'll get access to a dedicated portal that will help you organise and email your contacts to check on their progress, so you know exactly how much money you're on track to receive.
To help you even more, 3 is developing a Facebook widget which will be able to be posted on users' home pages to promote the free 3 SIMs to the whole of their social network.
Let us know if you'll be signing up to be a 3 Free Agent below, and if you think the scheme will work. Don't forget to check out our top 10 mobile phones to see which you handset should be popping the SIM in to.
