Amtrak and AT&T Wireless put Wi-Fi hotspots in six Northeast train stations: Boston (Router 128), Providence, New York (Penn Station), Philadelphia (30th Street), Wilmington, and Baltimore (Penn Station) have Wi-Fi service starting today, according to the press release. These stations process a million passengers a day. It's $10 per day per location--unlike T-Mobile's $10 per day throughout the network fee. They also offer a 5-pack ($30 or $6 a session) and a 10-pack ($50 or $5 a session).
Business subscribers only who already participate in AT&T Wireless's "Corporate Digital Advantage and Wireless Business Advantage" plans can purchase unlimited monthly service for $40 per month to supplement voice plans or $35 per month to supplement data plans.
Roaming wasn't mentioned. This pricing is clearly out of whack with the current trends, and should dramatically suppress usage unless AT&T Wireless is also aggressively promoting resale. Given that competitor T-Mobile is offering all you can eat Wi-Fi at $20 per month for all existing voice customers, not just business plan customers, AT&T Wireless may have misgauged the price sensitivity in the field.
