i've looked into a lot of the available spyware and keyloggers. None of these options will work in my situation. Wife has a new model iphone but I do not have the ability to install the spyware on her phone. I cannot jailbreak her phone .. and some of the spyware that do not need jailbreak work only if I know her icloud password which i do not.

Are there PI services that specialize in retrieving data from an iphone without physical access to the phone? like remotely install something? I searched the internet but most of the PI seem to focus on her social media monitoring .. but no actual monitoring of data being received and sent on the iphone through various apps like whatsapp, signal, and whatever other means.

Can't help you with the spyware but you said in your other thread that you had the pin and password to her phone. That makes a big difference. You might also want to test that password to see if it works with her iCloud account. Before you do that, make sure she does not have notifications set up on her phone. Same with the spyware, test it on your own phone before putting it on hers.
