Currently, the Wyless Group is the only Tridium-approved service provider in the continental U.S., and thus the only supported SIM card source. In addition, development and testing of the GPRS modem option used Wyless provisioned SIMs. However, it is possible that other wireless service providers may be approved in the future. Note that an appendix in this document provides details specific to Wyless—see Wyless as service provider.

The GPRS modem option is available bundled with a Wyless SIM (NPB-GPRS-W). Also available separately are the GPRS modem option without a SIM (NPB-GPRS), or a Wyless SIM card alone (GPRS-SIM-W).

Service provider connection costs and plan differences are currently outside the scope of this document. Consult your Tridium sales representative for more information on these items.

In turn, the service provider typically subcontracts with a cellular operator to provide network coverage. In the case of Wyless in the U.S., this operator may be T-Mobile USA. The name of the cellular operator may appear on the SIM card, however, the system (JACE) owner deals only with the service provider for all billing, as well as all required support.
