Calls/Texts over Ethernet?

Just looking for some advice really.

I have used my calls/texts over WiFi in the past and so I assumed you would be able to do that over a wired ethernet connection too if your SIM is present but I'm finding this is not possible and my phone prompts me for a cell connection to do those things. So all I can do over an ethernet connection is use Web and apps basically. Is that right or maybe I'm missing something?

I have an S21 5G from O2 on a PAYM contract and am connecting my phone to my home ISP router over an OTG cable with LAN/RJ45 at one end and at USB C the other going into my phone.

Would appreciate any advice.

Functions you mention are wifi and cellular only so won't work over a fixed BB connection.

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.

Cheers for the info.

Real curious though why you can call/text over a WiFi connection to your ISP router but not over a cabled connection to the same router? I assumed your cell provider would just have an authenticated & encrypted Internet gateway that it would pass the traffic over if you weren't connected to it's network?
