Why can't Android Device Manager locate my phone?

[lwthestommo]

I lost my phone the other day in my house but I can't find it. So I tried to use the android device memory to ring it up. but for some reason it cant locate my phone.

The phone may be powered off.

Or the wifi and mobile data could both be off.

Have you tried just calling it and listening around the house for the ringtone?
