My phoneiPhone was stolen last two month before inago around 16 februaryFebruary 2019. I made sure it was in Lost Mode in iCloud and it was immediately in Offlineoffline status when I openopened iCloud.
I am positive the thief switched it off. Now I am 100% certain the Find my iPhone 6 option was turned on on my iPhone, but will the "Lost Mode" be of any help if it was not turned on on the iPhone? Would it be showing "Offline" if I did not turn on the option?
