Can you track a iphone without a sim card?

My sister lost her iPhone 4S. If the person who stole it can we track it if they took the sim card out? If they try to activate it with another sim card will it work?

Yes if it has find my iphone app

Yes, it will work with another SIM card. Try using the app Find My iPhone on a computer or another phone. You can also contact the police if needed.

No. Yes, because SIM cards are transferable, but they would have activate that SIM card first so that it would work in that particular phone.

If there's no sim card it won't connect to your carrier. If the person puts in another sim card it would work. If they took the original one out you can't track it. But if you report it stolen then your phone can go on the blacklist by its IMEI # and the person won't be able to use it. This is what i believe to be true. May not be 100% correct

If you activated the Find My iPhone on iCloud.

You need to have set up Find My iPhone/iPad on your device prior to it getting lost or stolen. If you did, go to https://www.icloud.com/...cloud.com/ in your web browser. When you log in, Find My iPhone/iPad will immediately begin trying to locate your device.
If there's no result, I suggest you notify your service&phone provider and give them both your mobile phone number and IMEI number. They may help you block it. To prevent your new idevice from being stolen or lost in the future, I suggest you set up Find My iPhone/iPad in iCloud on the device and apply some free anti-theft app like iLostFinder. It will take pics of the thief or finders when she/he tries to open your device and then send the pics to your email.

  • If you take the SIM card out of an iphone can the police/ family still track you? So I watched this movie called SALT it's not that old but it's a good movie. In one part she takes the SIM card out of the phone so no one can track it. But is that also true with iPhones? Like of you take the SIM card out can the police still track your phone.
