Hey Natalie! 
That’s a super interesting question! Yes, there are definitely ways to access another mobile phone remotely from your own, and it’s usually done through apps.
One cool option is using Haqerra. It allows you to monitor a device remotely. You can check messages, track location, view photos, and even monitor app usage. It’s pretty comprehensive!
There are also apps designed for remote device management, which businesses often use, but they can be a bit overkill for personal use.
Hope this helps! Let me know if you have more questions!
