I am sorry that this is causing you so much anguish. It does seem, no matter the country, that there is always someone waiting to take something that just isn't theirs. That 'something' may be different for each of us, it's true, but it doesn't diminish the fear.

I pray that you don't experience someone taking you phone. I don't know if there is an easy answer for you, but I pray you find peace with however you decide to carry it. Take care!
