What happens to a t mobile iPhone that is lost?

I did not loose my phone. But I know they give me a new one with a fee and I was told by the company that they lock the phone. But what I want to know is can they lock it without the SIM card? And when they say lock do they mean just unable to use another carrier on it or lock the whole phone completely.

How to track someone's location on an iPhone?

My parents have a nasty habit of showing up at my dorm unannounced. Now, normally this wouldn't be so bad, but I have a whole day planned out with my boyfriend, who my parents don't know about because they're over-protective and would force me to break up (as they did to my older sister more than once).

So I want to know how I can track my mother's phone, whether through iCloud or her Facebook account (I have her username and password for both, because she shares them with me freely).

I don't have access to her phone because she's in another town, for now. So I can't manipulate any apps on her phone.

American-version iPhone5s unavailable in China?

After being in China for some days, I brought an iPhone on a discount, to find nothing accessible in China. I wanna install some useful apps, while the app store, as read by the screen, does not run in the Chinese market. Moreover, a VPN app from Android does not work on iPhone, either. I asked shoppers for help, only to be told no possible way to manage it.

How to get past the activation screen on an iPhone if it asks for the pervious owners Apple ID?

I just recently bought an IPhone off of eBay. But when it arrived and I went to set it up, it said it was already activated under the previous owners Apple ID. Where you have to log into an apple account. Now I have tried several times to contact the owner so I could get passed this screen, but they won't answer. I gave it about a week and a half, I'm becoming impatient. Is there anyway I could get passed this screen without the Apple ID and password?
