Each instance of this “cellular stack” will be referred to as an executor for the rest of this document. In such devices, there are assumed to be “multiple instances of the cellular stack” running in parallel which are each able to maintain registration, monitor signal strengths, perform handovers and listen for incoming pages. This section defines the various objects and establishes the terminology used in all MB documentation related to multi-SIM functionality.Īdvancements in hardware have resulted in devices that can maintain simultaneous registrations with multiple cellular networks. However, this is outside this documentation’s scope, which instead focuses on a WWAN miniport modem that is capable of presenting multiple and simultaneous cellular stacks to the host. It is possible to support dual-SIM/dual-active functionality with multiple independent modems, where each modem is a separate device and operates completely independently. NDIS Modem Interface Specification Existing Interface and Feature Gaps While the framework defined in this specification can theoretically support an unbounded number of modems and SIM cards, Windows 10, version 1703 and later supports only the dual-SIM/single-active (DSSA) scenario end to end. Such a limitation does not exist in the non-phone PC model as all SIM cards are used for data connection. Most typical multi-SIM phone devices have dual SIM slots but are limited to one primary SIM card supporting data while the other only supports voice features. This allows them to truly harness multiple active radios at the same time instead of having one modem with multiple SIM cards like a phone does however, due to the rise of eSIM and scenarios in the enterprise, the demand for multi-SIM-per-modem support on non-phone devices has increased. Traditionally, non-phone Windows devices have not been configured for multi-SIM modems because they have fewer physical space restraints than phones.
