Can I find my stolen Iphone? - 1

Okay so today while I was at the gym my Iphone was stolen:/ so I looked about and couldn't find it. I did the usual things like searching everywhere and asking the staff but nobody had given it in so I believe it's been stolen. I know find Iphone can track the location of your iphone but when I try to track it, it says its offline? But I have 5000 gb's of 3G available on my phone so does this mean they've removed the sim chard or something? Also if my network blocks my sim could I still track it?

You might be able to have it tracked by the company you should call.

You can track your mobile only if it is online. You can ask your network provider but they can only disable it.
