I’ve just ordered a stack (30) of UK sim cards for Wikimania. This is a mix of dual normal/micro sims, and also some nano sims..

They’re with giffgaff [1], and come with 5 GBP credit. If you get a £10 “goodybag” [2], it comes with 1GB mobile data and uk minutes/texts. Can get 4G on it too.

International rates are at [3]

Oh, and you can contact anyone else with a giffgaff sim for free too.

I’ll be down in London from the 5^th, so if anyone wants one, come find me.

Sam
