My question is:

Hi,

It is not possible to clone a SIM card, because there are many files on it that cannot be read by end users (the card itself enforces these access rights). In other words, since you cannot copy some files from the original card, you won't be able to create a 1:1 replica.

This is a universal limitation, which applies to any kind of equipment that reads SIM cards.
