T-Mobile USA has announced a promotion to give subscribers of its cellular phone service free access to its HotSpot Wi-Fi network during Saturdays and Sundays. The company runs some 6,500 hotspots, most notably in Borders and Starbucks locations nationwide, as well as in FedEx Kinkos, some Hyatt hotels, and in the airline clubs of American, Delta, United and US Airways.

The promotion is open to both prepay and postpay customers, as long as they can receive an SMS message containing a passcode for the service. The passcode would be good for the entire weekend, T-Mobile said. According to the HotSpot Web site, the promotion would be available for a "limited time," however no specific end date was provided.
