Ive 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..
Theyre 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.
Ill be down in London from the 5th, so if anyone wants one, come find me.
Sam
