So, I need text messages from my secondary phone – either on my primary phone (both Android, both Samsung Galaxy) or on a web-based service.

The forwarding must be near-instant. I can wait a few seconds; maybe a minute, but not two. The setup must be reasonably secure and reliable.

I’m looking for a trustworthy app; willing to pay, but would prefer free trial to see it really works. I don’t want to send all my message unecrypted through some server in someone’s basement, but I’d consider a professionally run service. E2E is gold, but must be practical.
