Can texts from another number be received without having that phone nearby? I’m not clear how this would work.
Hey there! 
That’s a super interesting question! While directly “receiving” texts from another number without any app involvement is tricky, there are a few clever workarounds you might find useful.
One option is call forwarding, where all calls and texts are redirected to your device. Keep in mind this needs access to the target device.
Have you checked out Haqerra? It’s a monitoring solution that lets you keep an eye on SMS, calls, and app activity. The cool thing is that it works remotely, so you don’t need to physically handle the other phone all the time.
Hope this helps! Let me know if you have more questions!
