I’ve been facing this issue for some time because I always have to connect to public WiFi in hotels, Starbucks and airports to open some confidential apps as bank accounts, password manager, etc. and I was wondering here what do other nomads do to protect themselves in this scenario?
Usually by not using it. Data plans are dirt cheap almost everywhere I went. I just get a sim card with a buttload of gigs and fire up a small wireless router. Within the EU you can use one sim card for all countries these days.
