you have an example where you are forced to use a mobile device? genuinely interested cause while I have a smartphone I don’t have hardly any “apps” on it (on my iphone all the “apps” are on the first “page” (without grouping). I do not like the idea of losing a phone and potentially someone getting access to my entire digital life (my phone password is 6 zeros) and I genuinely do not use phone for anything important
HMRC in the UK / multiple Government Portals. Have you been to India (Air tickets)? Or China (Wechat/Alipay QR codes or you go hungry)? And see my example above regarding US woman at Hilton in Rome.
I would immediately change my mobile service provider, this is an easy one and choices are plenty. financially as well, you can save yourself a lot of money if you have a cadence for switching providers
