How To Find The International Missed Call Mobile Number?

When phone is powered down and someone leaves a voicemail, why can't I see their number under "missed calls?"?

• Hello. I have a DROID Global. Verizon, of course. I power my phone down to conserve the battery. Someone I'd like to keep in contact called and left a Voicemail while my phone was powered down. I turned my phone on and was able to listen to the Voicemail, but I cannot retrieve the number. It's not in my "missed calls" and there is no option on Voicemail to review the phone number. I checked MyVerizon. I can't find anything. Is it not recorded anywhere? Is there a setting on my Voicemail I need to change? I went through the options and turned "call back" on. It didn't work. Might have not been related. If you know how I can get the number of the caller, let me know. Thanks!

• Answer:

  It's not in your phone's missed call history because your phone was powered down so therefore your phone didn't know that it recieved a call and the call back option didn't work because that person hid or set their number private.
