Plausible. Only Rogers still has working 2G.

It doesn't matter what the network is doing; the phone needs to disable 2g. There's various ways to get the phone to downgrade to 2g otherwise, eg https://montsecure.com/files/2021_downgrade.pdf

Android has it as a toggle: https://source.android.com/docs/security/features/cellular-s...

iPhone disables it for phones in lockdown mode.

And if you have a modern enough SIM+phone combo, it won’t even display the 2g network as an available network, nor 3G on my device.

I wonder if this mostly hit international SIMs, since they wouldn’t be running the same level of SIM code to prefer various network locks like a local SIM.

Helps you stay under the radar and gov services over SMS is a lot more advanced outside of Canada if you want to do some fraud.

It might just be that your carrier retired its 2g/3g network, not that the phone/sim refuses 2g/3g connections. If some cell tower popped up claiming to 2g/3g, your phone still might happily connect.

Which is interesting in that they very publicly shut down the 3G network last year.
