SIM Card Requirements
The CloudGate has an integrated (U)SIM interface compatible with the ISO7816 IC card
standard. The 3GPP standard defines three operational voltages for the supply voltage
of the SIM card: 1.8V, 3V and 5V. The CloudGate supports two voltages: 1.8V and 3V.
The 5V-only SIM cards are rarely used and are not supported by the CloudGate.
General requirements:
Changing of SIM cards while in operating mode, the so called "SIM card hot-
swapping", is not supported.
Detection of the SIM card removal can take up to 30 seconds.
The CloudGate will not be able to communicate with the SIM card after re-
insertion. As a result, the CloudGate needs to be reset after re-insertion of the
SIM.
The description on how to install the SIM card is given in the CloudGate Installation
Guide.
