I want to see who has called me for the past three weeks?
When you open the phone app, if your history isn't showing by default, press the menu key and look for call history. Or you can sign into My Verizon and view your call log, if you're the account holder or account manager.
Call log on the phone?
You can also log into your MyVerizon account and check there.
Or you can just tap on the Contacts Icon. Here you should see four tabs: Phone, Call Log, Contacts and Groups. Just tap on the second tab from the laft, Call Logs, and that will give you every incoming and outgoing call, including missed calls. If your tabs do not say Call Log and Groups, it might say Recent and Favorites. Recent is the same tab as Call Log, just a different name for the same thing.
