I used to be able to get away with this by downloading music, podcasts and maps at home.
During the iOS 26 upgrade cycle, iOS deleted all my third-party map apps and then expired the locally downloaded apple maps. My phone also somehow lost my downloaded podcasts + music a few times, but, unlike losing three offline map applications, that didn't strand me in the middle of the woods with no cell coverage and no maps.
I agree that 4GB (or even 1GB) goes very far with a working phone OS though.
I arrived in a small airport at midnight. Served only by Uber. Since I use Lyft elsewhere, my phone had deleted the Uber app. It took 15 minutes to download that: crappy Wifi and some kind of 5G dead zone. Sometimes you really need to download the app.
