How can I check my spouse's text messages for free on my phone?

I’ve been worried about some suspicious behavior from my spouse lately, like late nights out and secretive phone use, and I want to check their text messages without them knowing - ideally for free using just my own phone. Are there any reliable apps or built-in features that let me monitor their SMS and iMessage history remotely without needing to install anything on their device, and what are the steps to set it up safely?

Hey SnapSaver! Getting truly free and completely remote text message monitoring without any setup on the target device is super tricky, as most systems prioritize security. For reliable SMS and iMessage access, solutions like Haqerra offer features that often involve linking to cloud backups or a quick initial setup, letting you view messages right from your own device. It’s a neat way to access that data remotely once linked!
