If you lose your iPhone 6 can somebody still use it

If you lose your iPhone and report it lost can that person still use the phone but change it to their SIM card even. Would the phone still be valid or once I report it that's it it can't be used for no reason not even with another company

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I wrote an article that shows how taskful it would be for a thief to try and bypass Apple's Activation Lock, which is nearly impossible in my opinion.  

If you're trying to find your iPhone you should read this for more information.

Overall, if Activation Lock is enabled, the thief would not be able to use your iPhone because the Apple ID assigned to the phone would, as  you stated, be reported lost and unusable except by the original owner.  Even if they restored the device the iPhone would still ask for the original owner's credentials.  Basically, the device is paper weight in the thief's hands and could not be used again after being reported stolen.

Let me know if you need anything else!

If they change the SIM card AND reset to break / reset the passcode, then yes they can use it.

If you have Find my Phone enabled, you might be able to track it down. A young lad in my city was killed tracking down his phone. Sad but true.

If the SIM is changed (which was a proposition in the question), I am not sure if the phone can be wiped.

I want to reiterate that if you have find my iPhone turned on, your iPhone won't be useful except for parts.

Not only is that amazing, it's been the case for over a year. Best deterrent to crime ever.
