At home in peaceful safe backwater don't give it much concern
However travel?
My android i can lock, however can thieves get passwords etc via the sim, my data card is basically just music pix no bank stuff or password.
Over years stuff sems to have been stored by clou, samsung, apple and google.
As for passwords I recall Fry on QI logical advice, write not on macine of couse nor mobile but a oiece of paper
I used to think sendind such stuff as in line data in Euskera will deter most but with AI translation ?
You can see how quick some AI or googe translate hacks this revalving item
"biraka behar al dut"
Ive got a master password manager and leave paper with partner
Any tips apps apprecited I'm prpared to pay for proven apps not concerned odd ad or 'light spam' as will delete once home
I do have 2 cellphones one I use local sim
My Thai one I leave in hotel friens/family house when out on the lash as re registering and Thai banks is such hassle
If II lose my SFR French sim like uk walk in shop $1-0 clams get new one, no registration.
At home I dont answer unknown numbers but half a dozen fights hotels youve sent your number makes this tricky of course with time can google number and if it says Deutsche Bahn , Hilton Brno, or Virgin Trains or Air France easy
