Will an iphone in lost mode enable celular data on its own? My iphone has been put into lost mode by some hackers like this.

I have regained access of my iCloud account and removed the lost mode from there however the phone has not updated yet because I always have cellular data disabled(because I dont have a plan for it) and I see that its not connecting to wifi. 

I can get 10MB data for a day from the Cell company.

My question is: Will iOS enable Cellular data on its own while in lost mode?

I have an iphone 4 with ios 7
In short - if your device doesn't have cellular, the lost mode transmission won't be received until / unless it rejoins or connects to the internet via WiFi or someone puts in a working SIM chip with compatible data plan.

In this article, you will see the following. Hopefully this answers your question.


  
  If you used Lost Mode, when tracking begins, you see your device’s current location, as well as any changes in its location on the map.
  
  If your device is online  when
  you put it in Lost Mode or lock it, it locks and tracking begins (if
  applicable). If Location Services is turned off on the device, it’s
  temporarily turned on to track your device’s location. A confirmation
  email is sent to your Apple ID email address.
  
  If your device is offline ,
  the passcode lock and tracking (if applicable) take effect the next
  time it’s online.
