Outgoing calls don't work when 5G is on

Hi,

I’m using a Samsung Galaxy S22 with a Saunalahti Prepaid eSIM.

When my phone is connected to 5G, outgoing calls do not work. The call ends immediately. Mobile data works normally. However, when I switch to 4G/LTE, calls work normally.

Could you please check what might be causing this issue?

Thank you!
