I am experiencing an odd issue that is seriously hampering my ability to verify/confirm things like identity, and thus run my daily life:
Issue: certain transactions conducted here in the UK via mobile apps require me to confirm my identity (or email/phone), e.g. banks, digital signature providers, mountain rescue organisations... To do this, the organisation/company sends an SMS text message with a code, which I must enter in the app. This works faultlessly if the organisation is in the UK (using a UK app), but I receive no such texts if the organisation is in (say) Switzerland (and I'm using their app). Something stops these texts from getting through. It happens time and again and with a variety of apps/organisations.
Can anyone shed any light on this frustrating behaviour? It feels like it's security related. It's not my phone, as it happens on two different ones.
