Dual SIMS on S9+ and G3 Frontier

Is it possible to have the same SIMS chip on the Galaxy S9+ and the G3 Frontier (watch)? So that if you phone rings the watch rings also and depending which is the closest you could answer. They would have to have the same phone number and not be connected with Bluetooth. I asked Ting and they said no. Has anyone tried it? Can the SIMS be modified to have the same number?
 
Just for information, SIMs cannot be modified to have the same number. For one thing the phone number isn't in the SIM: the network associates the SIM id to the phone number. And if you managed to clone the SIM the network will detect two instances of the same SIM id connected simultaneously, and most likely disconnect both (it will be detected as a fraud attempt, so the simplest thing is to cancel that SIM id completely then get a replacement SIM to the real owner).

In short, it's the network who control this, so if they say they can't offer that there's nothing you can do.
