Yes. It's a company called Pinwheel, they provide phones pre-setup with what is essentially MDM, but geared towards child usage.
I can do the following remotely from the "caregiver portal":
- Install/uninstall apps from Pinwheel's "curated" app list
- Enable/disable Google Play store (apps still require approval)
- See their texts and calls (including actual content - they know we can see this, we don't hide it)
- Approve/block contacts; or, allow them to manage their own contact list, but blocked contacts cannot be bypassed
- See their live location and location history
- Set schedules and modes to enable/disable apps/features at certain times, and after any specific duration if desired
- Remove the lockscreen passcode
...all remotely.
If your FIL can't handle smartphone stuff, I would absolutely recommend something like this for him.
The catch is that Pinwheel costs about $15/mo per device. Worth it IMO. They also have their own optional MVNO plan, with everything rolled into one price. I forget how much it is - I just put my kids on Mint Mobile.
