I lost my phone two days ago and I am trying to erase the data but it keeps saying ''we cannot reach your phone right now". Is there another way for me to delete data?
I presume you enabled the "Find my phone" setting in your phone.
This only works if your phone is not switched off, has internet connection and has still your ms account.
The only other way is if you used a PIN. In this case a hard reset is needed to get in your phone.
