Mobile Telephony

Yesterday I had a chat with Google Gemini about mobile telephony. Specifically I was discussing Galaxus, Wingo and Coop Mobile. I told it that I was interested in a mobile plan in the same price range as Galaxus but using Swisscom as the mobile network rather than Sunrise. In the process of telling it about the Coop plans it told me go for Wingo, and specific promotion plan, rather than others.

This week I learned that mobile phones use mobile telephony for the emergency call system. This surprises me because I would expect them to use a fixed line rather than a mobile phone signal but also because when Swisscom or another telecom provider stop broadcasting on a frequency range like 3g, then all devices need to be updated to a newer standard. This means that all lifts need to be equipped with new mobile telephony devices.
