It's unfortunately not that simple. I'm South African. We have load shedding "stages", where each stage sheds 1GW from the grid.
We were just at stage 6 recently, and this means there are days with 1x2.5hr outages and 2x4.5hr outages, with maybe 2-3hrs between these stages to recharge batteries. In my experience the cellphone towers do not always have sufficient time to recharge their batteries.
I live on an estate with a cellphone tower owned by the largest network operator, and this is still an issue. SMS-based MFA becomes a problem when this happens.
Interestingly, I have never once had a fibre outage through years of load shedding. (I have battery backup for my fibre CPE.) I can easily get 200mbps to a local DC while people relying on 4G or 5G are completely cut off.
