Querying the cockpit with prepaid is only possible via WLAN
I use a PREPAID subscription with a data package for data roaming abroad. As far as I remember, in the past I was able to view and top up the credit at any time using the Cockpit app. Unfortunately, I deleted the Cockpit app and couldn’t find it anywhere, so I have to do it via a browser.
If I wanted to establish a connection to cockpit.swisscom.ch in France without WiFi, it took forever (it felt like at least a minute) until the browser gave me an error message, which usually said that this address could not be found can be.
I tried it with different browsers (Google, Chrome, Samsung Internet). The problem was always the same, only the text of the error message was different. It worked over a WiFi connection.
