SIM interface testing

SIM interface tests are performed to ensure interoperability between a SIM (Subscriber Identity Module) and a mobile device, independently of the manufacturer and operator.

Our SIM interface tests are available for end products, modules and reference devices.

The tests to establish interface conformance between a cellular mobile network, a device with cellular wireless technology and the SIM are highly complex.

For example, we test programming voltage and current, as well as parameters to calculate extra guard time requested by the SIM.

The conformance tests and certifications are required by leading interest groups and mobile network operators.
