Revert back to physical sim

Hello! A few days ago I had to use a new phone as my old one was sent to be repaired. Since that new phone supported esim I converted my sim to an esim and used it in that phone. Now thatI  have my old phone back,a phone that does not support esim, I want to cotinue using my physical sim as always. I insered it back to the phone, yet it does not seem to work. The phone reads it, but I have no reception, cannot make or receive calls or use mobile data. How can I deal with this issue? Do I have to order a replacement of my sim card?
