RPi LTE HAT

Well the primary concern here is Device Tree Overlay.
Does the company provide them or are you on your own?

Many of the platforms this supports would have to have their pins muxed via overlay for this device to work.

There are certain precompiled overlays available for RPi. I would look there to see if there is any public support.
Or any support at all....
 
Looking closer this probably does not use RPI GPIO pins at all. So no ovelays needed.
The header is pass through only. No pins.
Instead it uses a pigtail for usb from RPi to USB adapter with PCIe slot and SIM.
So external USB cable used.

I am guessing on some of this. There is a USB jack for something.
Generally USB is not available on the 40 Pin GPIO header either.
 
I use an external USB adapter for my RPi2.

I am probably wrong about this.
Notice it has a jack for audio output.
This might come from the GPIO pins. I2S pins.

But with no instructions who knows. Buy one and find out....

Note the board text at back of mini-phono jack. It says Android.
What does that mean? These people are clueless.
 
Looking at a version with the SIM7600 cellular card embedded they use the audio jack for calling (Voice-over-LTE).

Not sure if SIM7600E is supported on FreeBSD.
 
The Pi Shop version with SIM7600 offers a UART-USB converter onboard.
With that you should be able to use GPIO pins only.

I use the SixFab hat. It only needs the 40-pin connector for power. Matter of fact, you can run it with just USB, which I do to make the hardware more compact, and feed +5V directly. To the OS it just looks like a USB serial modem.

To be clear, it has Gpio pins that can do useful things, but they are not needed.

Which Raspberry Pi (or equivalent) do you use this with?

Right now with a Pi 0 W; originally I tested it with a 3B. Since it is USB only, it really doesn't matter much.

I have the LTE + 4G version; I know other versions (3G or 5G) also exist.

I use only a physical SIM of my own (not the one provided by SixFab); I don't remember seeing any mention of eSIM in the documentation, but since I didn't look for it, I might have missed it.

Also how would I know if this supports 5G and or eSIMs?

Do you realize why eSIM exists?
They will tell you its about size. They can't fit a sim slot anymore.

The real reason is lock-in. They gotcha.
This will never ever come to PC because it is exactly the opposite goal.

5G is marketing except in 1% areas. Most places it's 4.5G in my opinion.

I have given my opinions on cell modems before with you. Sierra. MC73xx
