I am going to California at the end of this month. Can I buy a USB data stick here in the UK (e.g. this one from Vodafone), buy a SIM of some variety in the USA and use them together for internet access?
Or, in my case: Commute by bicycle in Oxford at the moment (Youtube link). It was more slidy this morning (Wednesday) than it has been all week. I should probably have invested in spiky bicycle tyres.
