visiting usa looking for sim and data advice

[frankco]

I will be visiting flagstaff az area for a couple of weeks from australia. I neeed to make calls and access data via wifi on my t-mobile g1 bought unlocked in australia. Timobile is the obvious choice of caarrier, I guess. But how to do it? Can buy their sim card but not sure how to access wifi? Can I pay for wifi from any carrier as I go with credit card? Any suggestionsuggestions appreciated.

Its very difficult to answer your question. Generally in Unlock phone their is no need the pay for the wifi because in the unlock phone the wifi is used by the code also. you can ask to the sim provider about your service. they can help you about this.
