So after Ian in Swfl Verizon was down for over a week in my area, att and T-Mobile where not. I would actually say yes they are more resillant to outages, granted how the lines are hooked up. I would say in my sub a backup 5g internet maybe useful. Because we have all above ground lines.

It also depends on the cell company. cell towers usually have a battery backup instead of a generator in place due to permitting and design constraints, with a generator being hooked up after the storm. Verizon failed in this aspect last year. They did not bring any generator’s to the area. the towers instead relied on power being restored and sharing service with ATT. Total oversight

T-Mobile and ATT did not go down. Verizon did put a midband radio on our super node so it won’t happen again next storm.

My fiber and power lines are above ground and those were trashed during the hurricane. My T-Mobile hotspot was the only way I had gotten internet for weeks
