My niece's ex husband knows her every move and we suspect her phone is being tracked. What can be done about this? (Answers in plain English please as we are technophobes).
Every where she goes she receives a text/call from him saying "what are you doing at so and so's house/in that shop/in that pub etc"
She is not being followed so this is the only answer we can think of. She has Find My Phone installed on her phone.
He will have been able to get his hands on her phone as she leaves it openly laying around the house and he visits to see the kids on occasions
If she's got find my phone, and he's got a gizmo which can track GPS, that's how he's doing it. OH's boss tracks him when he's driving round because they follow the GPS in the vans - it must be something like that.
She needs to turn the GPS services off and see if she get the same level of stalking calls. Then try leaving the phone at home and see what happens. GPS trackers fitted with phone sim cards are relatively cheap and can easily be concealed in a car or even a handbag.
