The phone was still used for personal use regardless of being contacted by work being honest. The phone (and company laptop) was taken abroad because she was required to do a payroll submission and other work whilst away. Her bosses were aware of this. She wouldn't have needed to take the phone or laptop otherwise as she does have a personal iphone to use. If it makes a difference, she was on the hotel wifi, however it would appear that the wifi wasn't connecting all the time and unknown to her was switching to data.
