I have the "4g" logo on the screen showing that cellular data works.

I can recieve "messanger/whatsapp/" messages. I recieve "messanger" calls, but when I answer the call , it doesn't work.

I can't use web browser or anything that requires to send data online.

This problems occurs with cellular data only. (With WIFI everything works)

I put the sim card on another phone, it works without problems, which makes me deduct that it is my iphone that bugs.

I tried everything that was suggested ( reset network settings, turn on/off roming/ restrat phone/ remove sim card and insert it again. Installed iphone updates) nothing works.

See if you can borrow a friend's SIM on a different carrier and see if that works. If it does, that would rule out a problem with the phone.
