In Sweden the "minicall" network (POCSAG, ≈ 169 Mhz) is still active and in use by some niche industries.
I know of it being used for fairly mundane things like Grafana Alerts (or the equivalent), but in circumstances where you need to reach people in areas where cellphones are forbidden or lack coverage (like security sensitive data centers for example).
Snooping on that frequency band in ≈Stockholm it also seems to be quite actively used for sending machine-to-machine commands in some industries, perhaps not always that stringently authenticated...
Which I guess is a downside though, you need to take proper precautions in the "application layer" since the network is completely open.
