How do I find out who is calling me, when their name isn't stored in my phone?

Question

Someone called me twice from two different #'s, but it is so late i don't want to call them back. I know its not my family and most of my friends are on vacation because its Spring Break, how do I find out who is calling me?

Answer 1

did you try using *69 after the call??

Answer 2

you could either return the call and find out who is calling or follow the lengthier procedure of finding out from our telecom service provider, which may take a day or two before you do so.
