HP on Monday unveiled a new service that will push the scope of its business wider still. The PC giant has just launched “DataPass,” a new prepaid nationwide cellular data service that will let HP add MVNO to its list of endeavors. The service will give owners of compatible HP laptops with embedded 3G connectivity (and other devices?) the option to purchase a variety of time-sensitive prepaid data packages that range from $5 for 75MB of data good for only five hours, to $30 for 1GB of data to be used within 30 days of purchase. Other options include $10 for 150MB to be used within three days, and $20 for 450MB to be used within two weeks. DataPass uses Sprint spectrum that HP licensed specifically for the service, so expect coverage to be in line with Sprint’s nationwide network.
