No internet via LTE without a sim card.
A comparison shows you the differences. https://www.digitec.ch/Comparison/11224522-10397714-5678833 First of all: The most expensive one can also work with the GSM network and thus offers better coverage, although the speed is certainly not outstanding.
I had a Fritzbox like this at home. I don't think so, the SIM is installed in the device and is then connected to the provider via the web interface. SMS can be read, I think. But making phone calls is not possible, I think.
Yes, via the Ethernet interface. But it always needs a powerline pair, as one at the box and a second adapter somewhere in another room.
With the latest version of the firmware https://www.inside-handy.de/news/42327-fritzos-update-fritzbox-lte you can receive SMS. Do you have to send an SMS to recharge?
No, it is a pure data router.
Yes, that's exactly what this device is designed for. It works like an internet router in the fixed network, only the whole thing is done via mobile radio!
Yes, this is possible. Please note the return guidelines: https://www.digitec.ch/de/Wiki/560
No. The FRITZ!Box 6820 LTE does not support an external antenna (without a conversion). The following article might be of interest to you: https://www.fts-hennig.ch/ratgeber/antennen-kit-fritzbox-6810-und-6820/
Unfortunately, this is not exactly communicated according to the manufacturer and can also vary depending on the frequency/location/type of house/walls. A rough value outdoors is approx. 300m or 25m in a building.
The AVM FRITZ!Box 6842 LTE is unfortunately sold out and can no longer be reordered.
