This has been suggested as an idea on the ideas board and this was the response:
"[INTERNAL] From Nigel: "An action that I took from the Ideas meeting this week was to find out whether an O2 Femto cell would also provide enhanced service for giffgaff users - answer YES" We now need to confirm if this can be done from a front end perspective (ie, part of the activation process) with O2." - Thanks!"
So it might be coming in the future!
Here's a link to the idea so you can give kudos to support it: http://community.giffgaff.com/t5/Submit-Great-giff
Quick Edit: I've just checked when that response was given, and it was the 3rd of August 2012. So I doubt they're making much progress with it. I've posted a reply to hopefully find out if they are still looking into offering it. I'm going to need one soon!
