How long ago did you do the one month trial and was it a 2021 model or 2022 model? I bought a 2021 model from here last year and it shows not compatible with the new plans here. I bought a used 2022 model that was sold here earlier this year and it is compatible. I wanted to make sure I am able to activate the new SIM card when they make us switch from the old plan to the new plans.
To get around the issue of ordering a SIM card you could go online and do a search for an IMEI number generator, select a Samsung model phone and generate numbers until you get one that will get you a card and you can try and activate it in the non compatible phone when it arrives. You do this at your own risk as I don't know if it works. I do know that one person has activated a SIM card in a compatible phone bought at Best Buy and put it in a phone that showed not compatible and it worked. But I have not read if anyone has actually activated a SIM card for a new plan on a phone that is not compatible, again you would do this at your own risk.
