I have a Sierra Wireless USB T-Stick and it's working well whenever I need to use it. I am thinking about upgrading though and my laptop has a ExpressCard/34 slot that is unused. I know there used to be a T-Card for sale on the XT network, but is there anything available for the 4G network yet or planned (nothing on the Telecom website)? Does such a device even exist? It would be nice to make use of this slot as I hear these devices get good coverage.
