SentryNet enhanced its service offerings to include support of the advanced Linear PERS 4200 cell unit. This upgraded service means the dealer no longer has the burden of buying SIM cards now that the SIM is included in the purchase price of the cell module. This cutting-edge technology also provides a Web-based portal for the SIM management. A dealer can now track their inventory of enabled and disabled SIMs as effortlessly and intuitively as a few simple keyboard clicks. Companies wishing to sign up for this program should contact the SentryNet sales team for details at 800-932-3304.
