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.

Source? 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.
