In this chapter, I suppose that you have your mobile Wi-Fi device ready to roll and want to sign up with a Wi-Fi network. You may primarily be interested in using Wi-Fi hotspots locally, or you may want to use them for more distant traveling. In either case, the issues are much the same as when you choose a wireless cell phone provider. You should be concerned about
How widespread is the coverage?
What are the costs and fees?
Are there any discounts?
What are the roaming policies in place?
How good is customer service?
This chapter answers these questions. I'll start with a rundown of the major national networks. (You'll find a more complete listing of Wi-Fi networks with some of the smaller players and some non-U.S. providers in Appendix B, "Finding Wi-Fi Hotspots.")
