The real solution is to buy a burner phone, but I don't know how easy that is for a woman in the KSA.
I've been taking you literally, just for giggles, but I actually get what you're talking about. But I only said the solution to being tracked is to separate from the phone. You're saying that's not a good solution to the problem because it doesn't also solve the (I would say separate) problem of making people aware of itself. But most solutions are like that. If you don't know about light bulbs, you can't decide to use them, therefore light bulbs are a bad solution to darkness? No, they solve darkness just fine; they just don't solve "awareness of light bulbs" very well.
