Hello @George877 and welcome to the RobotShop community,

There are three operating voltages for SIM cards : 5 V, 3 V and 1.8 V (ISO/IEC 7816-3 classes A, B and C, respectively). The SIM7600A-H SIM card slot supports 1.8V/3V SIM cards.

You can check how the SIM card is placed in this image:

And you can find the wiki here:

I hope that helps!
