@Bozza35 A Sure Signal device will create it's own 3G signal which you'd be able to use.
To connect a the device you'd need to plug one end of the Ethernet cable into your Sure Signal and plug the other end of the cable into the Ethernet port on your broadband router.
Would this be possible in the environment which you work?
