Travelling to the US for Denmark and need (probably) a prepaid sim-card
I'm travelling from Denmark to California for a three week roadtrip. I would like to have a sim-card with unlimited data usage. According to our travelagent, it would be cheaper for me to buy it in Denmark, but that makes absolutely no sense to me. What I need is probably a prepaid sim-card, but not sure how to get one, and the price as I only need it for 1 month. Having trouble finding an emailadress to support, and can't get though via the phone-number provided. I'm starting in San Francisco (Fishermann's Wharf) and would like, if it was possible to pick up a prepaid card in one of the AT&T-stores. Can anyone please help? Other solutions are also welcome :-).
