according to Telfort I should be able to make unrestricted calls to any EU country.
But I cannot call the service number for the French train operator SNCF.
+33 892 353535
I can call this number using other telephone service providers. So the number works.
The Telfort client service confirmed that my phone is not blocked.
Can you tell me why I cannot call the SNCF service number? I need to call them to buy a train ticket. Thank you.
