Need instructions on putting SIM into Waveshare SIM7600A-H … where to buy …which one…etc
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!
