I have on several occasions experienced lost mobile phone connection when traveling abroad. My iPhone X was set on “automatic” and “international” and connected normaly up to a local serviceprovider. In some cases it allowed outgoing calls on other occasions it was just dead. A long conversation with the UPC service only revealed its incompetense and did not solve the problem. How can I solve this problem or rapidly get out of my UPC contract that still runs for 6 months.
