Can I clone my iPhone sim to use in a non-iPhone
I have a very cheap GSM phone I sometimes use when I have to trek to a relatively unsafe neighborhood. (Long, long story. I'm willing to tell it, but this would bog down the message.)
Anyway, rather than remove the sim from my iPhone and put it in the generic GSM phone (which does work fine, but it's a bit of trouble, and I worry about the wear and tear on the sim), I'd rather clone the iPhone sim and leave the clone in the non-iPhone cell. I do understand that using BOTH phones at the same time would very likely cause me some serious trouble (probably legal trouble at that), but that's not going to happen because that is neither my need nor intent. I just want to be able to use my account on one phone OR the other but not both at once.
Would any of the supersim techniques described here and elsewhere work for me (even though I'll always use the cloned sim on AT&T but just on a different phone)? Any guidance or thoughts would be appreciated.
