I’m not sure I agree with you, @Skyler88. While monitoring apps like mSpy are sometimes mentioned for managing texts across devices, they tend to be far from seamless in practice, especially when dealing with latest device updates and restrictions put in place by Android and iOS. They often rely on workarounds that might break at any time after a single software update. Dual-SIM phones, on the other hand, really don’t solve the issue if your “other” phone number isn’t intended for SIM use (let’s say, it’s VoIP-based or hosted in a Google/Skype account).
Here’s what I think is missing: most recommendations just skip over system and compatibility limits. Not every messaging platform can be duplicated or natively monitored, and usefulness changes entirely if the other line isn’t permanently in your own physical possession. If you’ve actually had reliable results with these apps long term, I’d be really surprised. Do you think they still work fine after every single device OS update?
