I am travelling in EU with a swiss travel+ subscription.
Suddenly my phone lost connection to the local mobile networks and i am unable to reconnect.
I tried switching in flight mode or rebooting the phone but the problem persists.
I also checked my subscription and there is no roaming costa or account block.
So the problem seems of technical nature.
Without a mobile network connection i am unable to contact the customer care and being abroad i cannot go to any shop.
How can i receive sunrise support?
