I went to visit London about six month ago. On that time i purchased a "Three" sim card from the airport. It was a micro sim and had nano and standard adapter. the price was about £15. I purchased that sim because it has unlimited 3G internet for 30days plus 300 min local call and 3000 local sms. But i am not sure if it is available now or not.

There was a vending machine just beside the first exit gate of terminal 4. I think from there you can choose the sim card by yourself.

Well, obviously Giffgaff isn’t going to be as good as the more expensive carriers, but you really can’t beat £12 for unlimited data even if it is occasionally quite slow ;)

I think they were around the South Bank / London Bridge / Chinatown area and had unbearably slow speed. Perhaps I'm just too pessimistic about it!

Oh no, giffgaff basically doesn't work in London! I learnt it the hard way when my family visited me last year. (I used to live in Cambridge where giffgaff is great.)

This is because giffgaff is a virtual operator over O2 and a subsidiary of O2 (think of a flag carrier airline's budget branch) so giffgaff users need to give way to O2 users in areas with many users. And in central London, it means there's little or no data bandwidth left for giffgaff.

So expect your goodybag to give you nothing but a dumbphone plan.

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
