T-Mobile has launched a new service for their phone customers. Every weekend, a T-Mobile phone (post-paid or pre-paid) customer can get free access to T-Mobile’s national HotSpot Wi-Fi network. This process is done by the user first logging on to the HotSpot with their laptop, then entering their T-Mobile phone number. The T-Mobile phone is then sent a SMS with a login and password good for the weekend on any HotSpot on the network.
