does GSM works if the phone is switched off

Hello Friends,


I lost my Iphone4. So trying to find out all possible ways to track it. It was ringing for 2 hours after I lost it and then its switched off. I am wondering if the GPS works while the phone is switched off if not then will the GPS work withough cellular service (network provider/chip/SIM).

I do not have "find my phone" installed.

iPhone 4, I lost my IPhone 4. And trying to f

GPS works without cellular. But without cellular you cannot make contact with the phone, and the phone cannot make contact with you.

Before the phone was stolen, you needed to enable "Find my iPhone in "Settings > Privacy > Location Services > Find My iPhone > ON". Sadly, the fact you are asking these questions proves that you did not. There is not way to trace your phone.


The application "Find My Iphone" is just an iOS app to track the lost phone. It is not a necessary part of the process. A properly enabled phone can be looked for by signing onto your iCloud account from any computer in the world with an internet connection.

hmmm, Because i m so sad i made a mistake, I wanted to say GPS and not GSM 🙂

Will GPS work (when the phone is switched on) withough cellular service and that way is there any hope of finding my Iphone.

We were really addressing that as the question, assuming it is what you meant to say 😉


It doesn't matter because if you did not setup Find My on the iPhone it cannot be located. That is the only working solution.

I have used it for two years and I did all settings only within first 3 days when I bought it, so I m not sure if I enabled that, i may have. In fact i did install "Find my Iphone" app but when the icons were increasing i removed this app (i know its most stupid 😟).

If i go to icould.com i cn see Yogesh's Iphone there but offline. (does it mean I have "find my Iphone" enabled)


I mostly used wi-fi to connect to the internet so cellular data was off when i lost it.

Along wiht what Rudegar and Varjak said, and as noted far above, if the iPhone has not been setup with Find My activated it will not be findable. If it has been setup but the iPhone is turned off, battery has died, it is not connected to the internet, someone has reset it to factory condition it will not be findable. Not by the iCloud tracking system, GPS, IMEI number.


The only thing left to do, besides keep trying with iCloud if you want to do that, is make sure the carrier knows it has been stolen so they can blacklist the IMEI number if they offer that. Blacklisitng will keep it from being used on a network and it is nothing more than an iPod then.
