I have a pixel 6, so I have ~1 year of security updates left.

I would like my next phone to use a data-only sim card/esim.

Now I still need my current number, and am okay with paying for it in addition to a data-only plan. What I would like is to leave the pixel 6 at home 24/7, and have a way of forwarding notifications to the new phone.

I am self-hosting many things, including ntfy, so if the phone could send an SMS to ntfy that would be amazing.

Are there any apps that do this? It doesn't have to just forward SMS, but all notifications would also work.

Should I even bother? Just leave it at home and check the SMS whenever I can? (Benefit of forcing people to use Signal)
