I bought a N900 a few months back and activated it on T-Mobile with their $30 a month "Monthly 4G" plan about a month ago. The plan comes with 100 voice minutes and unlimited texting and "unlimited"/5GB of data. The plan is just about perfect, except they consider it a "prepaid" plan and don't bill you, show any account history, and most importantly don't send any form of receipt (which I need so that my employer can reimburse me). I've called multiple times to T-Mobile and the only way to get any kind of receipt is to call, wait for ever to talk to a supervisor and then they can fax(!) you a one time receipt. I don't have a fax machine, and even if I did I'm not willing to put in that kind of effort every month just to get something that should be emailed to me or available to view on the website.

So, done with the long preamble, what kind of equivalent plans are available in the U.S. from other providers? I don't care at all about texting, and don't really need minutes. i just want data and a decent national coverage area as I travel for work regularly (although mostly to big cities). Work will reimburse me up to $30 for data.

Any options out there?
