For work reasons I'm going to spend 1 month in the USA (near Chicago). I was wondering if you knew any good, cheap and reliable company with which get internet in my cellphone for that period.
Thanks a lot!.
Plenty of options. Last time I checked, MetroPCS was about the cheapest, and they're famously flexible (no contracts). I don't actually use them (like many cellphone customers, I'm lazy and have stayed with my current company for many years just out of inertia), but my brother does and loves them. Dunno how good their coverage is in Chicago, but it's fine in other metro areas (I live in San Francisco and my brother lives in Boston, and his phone has been fine, and cheap, in both).
