I'm based in Switzerland and I have many IOT devices that I've been using since many years.<p>All my devices are only 2G compatible some have a Swisscom network sim and other a Sunrise network sim.
Swisscom will stop it's network end of 2020 while Sunrise end of 2021.<p>It's quite difficult to find answer to some of my questions online if anyone could help out it would hugely appreciated.<p>My main question is :<p>- Will Swisscom 2G sim roam to the Sunrise 2G network once Swisscom 2G network has been stopped ?<p>Then I had some more questions I was asking myself<p>- What happens when your provider stop his 2G network?<p>- Is there any backup plan for all the IOT devices out there still connected to the 2G network ?<p>- Or roam to other adjacent countries 2G network ?<p>Thanks in advance.
