APN settings not working with new operator SIM card

[user641]

Hello, I have been using a pp for more than a year and never had this problem, I got this SIM card from kena, a virtual operator that uses tim network.
It displays the 4G signal with "!" I have tried the automatic depection of APN simpydoing nothing, then the recommended by the operator, then some other possible combination, none work. On a degoogled phone it works without any problems or need of manual setup. Any tips?

Hello

Personally, I have to add the APNs (Internet + MMS) manually in Gnome control center.
