I got the, can't activate while roaming, with T-Moible USA while being up in Canada. There is a version of Google Messages that will activate that regardless. The second SIM, which is the eSIM though, never activates for me. I have tried everything and then some. I have contacted Google and the Canadian carrier, which is Bell. I have even tried that eSIM in 2 other devices. I just can't get RCS activated on that number for some reason.
