Sync SMS from Multiple SIMs/Devices

How to sync SMS's between 2 Android phones?
* If I have a SIM in 1 mobile, and a sim in another mobile that's not regularly with me, but is connected to the internet (wherever it is).
* The SIMs in question are from two different service providers, or two different countries.
* Mostly required for OTP's etc from the other phone that's not with me.

I moved this from the Galaxy Nexus forum (that phone is ancient) to the General Help forum for more appropriate traffic.

SMS is specific to a phone number, so I don't see how that would work with another phone with a different SIM. You could always use Google Voice and link both numbers to your Google Voice number: https://support.google.com/voice/?hl=en#topic=1707989

Thank you.
Unfortunately Google Voice doesn't work in my countries: UAE & Sri Lanka
I'm using a Note 20 Ultra.

Sorry, I'm not sure if you have any viable option, then.

There used to be some third party apps that would allow for a quasi SMS forwarding service to another device, essentially some sort of synchronization service the two devices would need to both be running in common. I saw one app earlier that even forwarded the SMSs via email. I don't think either of that is what you seem to be looking for, but look around play store or google and see what comes up.
