GPS phone location

[#1]

Need to know how to find my phone via number gps if possible 

[#2]

I'm afraid that's not possible through giffgaff @abidure, you'll have to have something setup to track your phone yourself.

Normally can be tracked via online like through icloud depending what phone you have.

This is something you have to do yourself.

If it's an Android you might have the Find Device or something similar installed. You can access it on your Google account. Or if it's a phone manufacturers app on your account with that company.

If it's Apple you can log into your Apple account and use the find my phone facility.

any apps on your phone, the phone will need to be switched on
