You don't need a SIM card to have a TOTP app they're totally independent
A VPN you pay for with crypto is probably more secure than driving to somebody's public Wi-Fi for this use case. Driving to a location, sitting around while uploading a massive video on public Wi-Fi, it's going to look very suspicious
Connecting directly to the VPN will still give away your IP unless you do that from a public location (which is not a bad idea). As for sitting around, select new coffee shops and find angles where cameras can't see you. Make it an irregular schedule
I suppose you could do that. Maybe putting an extra layer in one shoe will help with a limping posture if you're willing to go that far, but nothing is foolproof against AI
Use public transport, wear baggy thrift store clothes, preferably masks on. Will fool everything but the sophisticated (and expensive) AI systems. Won't work if you're in the UK or China because their governments are insane
Your IMEI number just got linked. You need a disposable phone and SIM. Or just go to one of those SIM swap parties where everyone swaps a used phone and SIM randomly from a basket
