Questions about cell only Qolsys system

Hello all. My in-laws have just bought a cabin in the mountains and I was looking to get a good panel for the cabin and was wondering are there any features that will not work on a cell only system because I don’t think they will ever get wifi at the cabin. So are there features with or interactive stuff that will not work if you don’t have wifi in the home? I would like at first to get doors and windows and glass breaks. And then maybe some zwave stuff in the future like lights deadbolts and thermostat

There are some features which require an active internet connection. You would not be able to take advantage of back-end integrations like Liftmaster MyQ, Lutron, or Nest. You also would not be able to use video cameras.

The alarm panel, sensors, and Z-wave automation, however are all controllable via cell only.
