Dear jjcarreiras,
You may be in an area without optimal network coverage. Try to move.
You are experiencing a mobile network problem. I advise you to restart your device.
If that didn't help, try changing the phone operator in your network settings.
However, if the problem persists, I invite you to connect to tango.lu and carry out the troubleshooting steps with the help of our chatbot. Here
Kind regards.

Thank you Diana for your message,
I see that it's not only my company that doesn't believe me, you also don't believe me.
The problem is not the network coverage, the problem happens all around the country: Kirchberg, City Center, Junglisnter, ... In some places I have excellent network coverage, as excellent that I can use internet with 4G. The problem happens when I try to call (even in those places with excellent coverage). For phone calls the network to be used are 2G/3G (except if you offer the service VoLTE which is not the case) and when my phone try use those 2G/3G networks it seems that I'm not connected to the network (but I'm still connected to your 4G network).
Changing the operator will not work either, my company has only agreement with TANGO in Luxembourg, the others (Orange and POST) are not allowed.
So sorry to insist, Is it possible that a phone number in roaming is registered in the 4G network and not in the 2G/3G ones?
I think the problem is in the parameters exchanged between TANGO and my company for the roaming.
Thanks.
