> I've been thinking about having a service that lets someone else randomize the location of your phone.

It’s called putting your old phone on eBay and buying a new (to you) one.

It really confuses the Saudi intelligence forces when they find a random dude instead of a Saudi runaway.

What I would like is to take advantage of some European mobile providers that have excellent roaming rates in Canada. Prices so good that a local Canadian could only dream of. I’d have 2 SIMs and put one in an rs232 interface each month that interfaces to a phone in EU so they don’t ban me for not spending enough time in the home country.

going offline would be suspicious

randomly roaming around would not

Can't the cell towers triangulate the phone location anyway.

yes but it won't give them your location, it will give them the courier's. the location history would put your device in totally random locations during the time you want to be anonymous, but it wouldn't look like you just left your device at home either in a way that didn't fit your pattern.

I think OP's point was that the phone would physically be with the courier for a part of the day.
