Anyone know how to clone a SIM card for AT&T to use a clone card while the original is still active?

Found this online


.
1
Turn off the AT&T phone and remove the SIM card. The process for removing the SIM card varies by phone model.

2
Locate the IMSI (International Mobile Subscriber Identifier) number. This number is usually found on the SIM card itself and is 14 to 16 digits.

3
Insert the original SIM into the SIM card duplicator. The duplicator will locate the unique key (Ki) associated with the SIM card. This is unique to that SIM and required for duplication.

4
Save the SIM profile to the duplicator. The process for doing this will vary by model.

5
Remove the original SIM card and insert the blank SIM card.

6
Copy the data from the original SIM card to the blank one. This process will take seconds. The blank SIM card now function exactly as the original one.

Anyone know where you can buy of these

Most probably I'm mistaking by there are a lot of countries where this is prohibited. Usually, they have to go to the operator and do it there. As they block one card and allow you to use only the new one. But nowadays when everything is possible, there should be different applications that will apply to do it.
