LordHamster,
You may already know this, but you may want to take a look at Red Pocket/Verizon for your backup line instead of Visible. I use it at their lowest level of 1Gb per month @ $99 for 360 days coverage. The next plan up is 3Gb@$180 for 360 days. Speeds are good and the service is rock solid reliable from the past 2+ years use. It does not seem to be throttled or low prioritized either as far as I can tell. No esim yet but with the new 13 Pro Max and dual esim that doesn't matter as much. For an "Insurance" line it is a good fit for my area. The same can be said for KnowRoaming on AT&T esim @$2.25/7 days/1Gb if you happen to find yourself in East Jesus or Smoky Corners, with only AT&T. I went to a wedding last year in a small Texas town that was AT&T only for miles in any direction.
