This is only relevant if you use 2G
That's already been decommissioned in the US, and 3G is due for the chop next year. But as I understand it 2G will be around in most of Europe until the end of 2025. Maybe phones need a setting to allow you to disable 2G?
Not that anyone should believe LTE and 5G encryption is unbreakable, but I guess at least it is better. Anyone know if those standards allow "no encryption" so the forced downgrade attacks could still work or has that at least been fixed in those newer standards?
