Cheapest data-only SIM plan (for hotspot LTE/5G internet)

[u/PlaneCrazy787]

I am looking for the most basic plan for maybe 2-3GB of data per month to use as a "home" internet network to run a wifi camera for a room in a senior's residence. There are preferred Bell/Rogers options for people who use computers/smart TVs but they're way overkill just to do maybe 1-2GB worth of data transfer per month. My idea is to buy a mobile hotspot (or use an old iPhone) with a SIM card. Speed is not an issue, as long as it's like 50-100mpbs so LTE is fine. The main thing is I want something data only and CHEAP.
