You'll have to tell us what phone you have Regardless, if the phone is outside of the service area, but it is getting a GPS signal you'll be able to find it if you have the password. If you don't have the password then recovering the phone is not going to be easy.

I misplaced my phone outside of the service area and dont remember my password. What can I do? I have the gps locator alarm on, i think, but cant send the msg. to activate it.
