SIM Card Requirements
The CloudGate LTE Rev 4 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:
CloudGate micro uses a 'micro' SIM formfactor.
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.
