Maybe I've picked the wrong phones, but I've also found them to occasionally completely die without any advance warning even if treated carefully, so I remain a bit wary about using them for anything ultra-critical.

And mobile phone providers over here don't guarantee even two nines of reliability, never mind that even 3½ days of no service per year is already too much for some critical things, like being able to get at your money.

And the local public transport association for example tries to disclaim any responsibility for any sort of problems if you're using their mobile ticketing app – if it doesn't work, though luck, your problem, buy a new ticket or pay a fine. Even if you've bought a monthly season ticket there are no special provisions, and the rules don't even differentiate between technical issues caused by myself [1], those caused by third parties (like the mobile service provider) or those caused by the public transport provider respectively its app developers themselves.

[1] Although while I can take care to keep it sufficiently charged, not letting it fall to the ground or whatever, I still can't prevent it from just randomly dying anyway, or the manufacturer issuing some borked update or whatever
