How to deactivate erase mode

Hi

Last night my pocket got picked and my iPhone 5 stolen.
In my impulsive actions I immediately went to iCloud.com and activated the 'erase mode' for my iPhone.
I didn't go for the 'Lost mode' because I knew location services is turned off on the phone.
But now I actually want to give that a try, the iPhone isn't erased yet, because the thief hasn't it connected to the internet yet (Wi-Fi).
I do have a data plan though.
Another question, when the location services are turned off, does that also automatically mean the device shows up as offline in Find My iPhone? Or did they turn the phone off...

Thanks in advance
