Interesting as Canada's system only works on LTE or higher (we still have 3G here).

I camped on 3G for a while because they kept sending out Amber Alerts at the "Presidential" level for custody disputes. Gov repeatedly denied any issue but haven't sent any for a while. Either people stopped "abducting" their own kids or they changed their threshold-to-blast.

Was your 3G on CDMA2000 rather than the 3GPP UMTS/WCDMA/HSDPA standards? That could account for the difference
One of our two big networks was, the other was not.
