How do I forward calls from JMP.chat number to SIM phone number - sh.itjust.works

Hello, I want to buy a flip phone to reduce distractions and am planning on getting rid of my Pixel. I currently have Cheogram installed on my Pixel and want to forward calls/texts to my SIM phone number. I’m not sure if the current flip phones support Cheogram well (due to the small screen). Any help is appreciated.
