Find My iPhone on iPhone without data
We have my daughter's iPhone set up to text and call, but it doesn't have any data. It does connect to wifi. We used to be able to see where she was when she was out and about with her iPhone through "Find My." Now, the "Find My" function only works to see her when she is connected to Wifi. This change happened when her phone was temporarily broken and she had to switch to another phone for a bit. How can I set up her iPhone so the "Find My" sees her when she is not connected to Wi-fi? I feel like a setting was changed somehow.
