Same phone shows different locations using Life360 vs Google Maps My mother's cellphone shows her in two different cities on the same day. The Life360 app shows she's in Chicago, while the Google Location history shows she's in Alabama. 

I think she might have given her old phone to my niece. Could both phones share location data even with different SIM cards?
Before giving the old phone away, did she wipe it? Otherwise, if she is still logged-in to that phone via Google, it's gonna think she has two phones and will show the location of both.
