I don't know a lot about i Phone's or the apps for it but if you talk to Apple (at a store or call them) or your phone carrier they can probably assist you.
With Android, you can still talk to the carrier for help.
Just remember that for every measure you take somewhere there is a countermeasure.
If she (or her 'friends') are determined to undermine you then they will find and use the 'countermeasure' and defeat whatever you have in place.
A combination of building trust, having conversations about the horrific dangers, and monitoring are the best you can do to mix with any software tools/measures.
The thing we tell our two daughters (9,11) and son (12) is that the blocking/restrictive type measures we have in place are not because we don't trust them.
It will also stop the removal of any monitoring apps you might install. Games have in-game chatting for instance, and there are the chat apps like kik, textme, textfree, ect. I emailed their support team and they said that they're working to improve the app.
So far we just have them on Text Me and have only seen a couple of texts that were truly wrong number instances.animal jam.
But these extra features, plus the privacy and safety issues, make messaging apps better suited for social-media-savvy teens.
I do know on Android there are several apps that allow you to lock out other apps so they're only accessible with a password.
One app to lock out would be the Settings app and the Play Store app. Locking out the Settings app will prevent anyone from going into the settings and enabling ' Developer Options'. so we cant go on spotify or fb or yt or stuff like that.
I would like to be more educated on how to check her phone the best I can with out her trying to hide anything from me please help me try to do that with any information that you can send or give me.
I found out by my older daughter that is 25 and has all ready moved out out the family home and is in another state that there is a app that looks like a game but you can send pictures and text through it without your parents knowing.
