"SIM CARD CLONING "
Introduction
SIM cloning is the process in which a legitimate SIM card is duplicated. When the cloning is completed, the cloned SIM card's identifying information is transferred onto a separate, secondary SIM card. The secondary card can then be used in a different phone while having all calls and associated charges attributed to the original SIM card. The phrase SIM clone is often used to refer to the SIM card that has been successfully duplicated.
A Lot of People have raised queries & are "Genuinely" interested in SIM Card Cloning.
Hence, let me explain the Basics:
Bottom Line First!:
YES, a SIM Can be Cloned**
** There are Special considerations & Not All SIMs available, can be cloned.
You Need Special Hardware. NOT the ordinarily available SIM Reader/Writer. These "Writers" can ONLY insert SMS & Contacts (*alap). Nothing Beyond That.
An Image Below will showcase the Functions that are usually carried out by the across-the-counter available SIM Card Readers/Writers (*alap):

The Hardware should be able to write to the EEPROM (or Programmable Memory) of the SIM.
Type of SIM:
Even though ALL Sims may look alike, the Software (Or in Technical terms: the EEPROM) has evolved (though Slowly) over the years. Reason: Better Reception like 3G & to thwart the efforts of Hackers & Cloners(*alap).
