These payg sims really serve four purposes - anyone think of more?

1) longer term, >60day( low usage) in a single country. Like a smartwatch, iPad, alarm system/car (use a physical esim adapter)


2) backup options (eg different provider as backup in home country, or just in case other short-term roaming esim stops working, or backup for home router if wired connection dies) - any longer, use payg connection to buy a cheaper 1-7day esim


3) short term stay (eg layover or 1-2 day and only need small amounts of data). If need more data, likely cheaper to buy a 1-7 day 500-1GB sim - so the higher PAYG rates shouldn't matter as long as it's reasonable enough

4) nontech savy family - one esim, don't switch back and forth or keep track of which profile to use - at least its cheaper than actual roaming?
