You mean cloneing when you say doesn't work at all? I don't claim to know much about it, but I hear about phones being cloned all the time, so I looked it up. Apparently it is possible, not something available to the average Joe, and quite illegal, so not an answer we should be looking into.
Yes, sim swapping is the obvious answer if your phones allow that and you don't have problems swapping, going wifi only on one of the two would be a reasonable fallback plan. I usually have the cellular part of the phone turned off the large majority of the time any way. I know folks who have even gone wifi only for their only phone.
