@VModifiedMind I can only speak for locally but alarms with SIM + Internet seems to be the default around here now and work reliably. I assume there was a cost to the owners to move from old monitoring.
Lifts, good question.. though I suspect similar or SIM only. Again not free to change equipment.
There was a cost at my grandads too. The cost to go fully IP rather than plug his old BT base into the routers ATA.. but that was in the effort to obtain the best call quality possible.
