I the US, Wide-Area Wireless Network (WWAN) choices abound. The competitive advantages for any of these depends on a number of factors that are decided from the user.
Availability - What is your local area, likely roaming area, nationwide or global roaming area, etc.
Cost - Not just the monthly plan, but cost of usage averaged out over three months of use. When wireless data is figured in, the minutes start adding up quickly (unless you have a plan that provides unlimited usage)
Hardware - what you need to get up and running.
