Is there a 4G and/or 5G replacement for the SM5100B cellular shield? I’m looking for an Arduino shield of some sort or a breakout board that allows for voice communication. So far all I find for 4G / 5G seem to be data-only (no mic or speaker connections) even though there are versions of the modules on these boards that will do voice.
You can try SIM7600CE-CNSE 4G HAT for Raspberry Pi, 4G / 3G / 2G. It has a built-in audio jack.
Thanks! I see that particular board can be mated with a full-sized Pi, a Pi Zero, or an Arduino as the user sees fit.
