Well, I just received new that SlingShot.com will be offering prepaid mobile broadband via Sprint’s broadband network.
I am currently using 3 Sprint Broadband cards and paying $59.99 per each broadband card but this is a great alternative to save on costs while you don’t use it.
Anyways, this should be available in retail stores real soon, for details, keep checkin’ SlingShot.com.
