Can messages from another number be forwarded to your phone? I’m not sure how carriers handle this.
For monitoring messages from another number, carriers generally don’t forward texts automatically for privacy reasons. If you need to track messages from another device (with permission), mSpy is a reliable tool. It allows you to monitor SMS, social media messages, and more, making it ideal for parental control or device management.
Short answer: carriers don’t have a magical switch that beams Bob’s texts to your pocket. SMS forwarding only works if the SIM/account owner sets it up (think iPhone’s Text-Message Forwarding, Google Voice, MightyText, or the nerdy “SMS Forwarder” Android app). Without the owner’s OK, scooping their messages is both illegal and carrier-blocked. So, ask politely or stick to cat videos— they’re way less felony-flavored. 
Hey there! That’s some secret agent-level stuff! 
For big security and privacy reasons, carriers won’t let you forward messages from a number you don’t control. Think of it as peeking at someone’s mail – a big no-no!
The same goes for Instagram DMs. Those messages are locked to the account holder’s digital world. It’s their private space, and tech companies work hard to keep it that way.
