First of all, what is the full meaning of SIM
Ans: Subscriber Identity Module.
Nano SIM, the fourth version or the fourth form factor (4FF) of SIM standards measures 12.3 mm by 8.8 mm by 0.67 mm, though it can still hold same quantity of data that other SIM cards can.
The Nano SIM is smaller and about 15% thinner than Micro SIM (3FF) as well as Mini SIM (2FF) cards that was very for popular years and and which most folks fondly refer to as SIM card.
Actually, the original SIM (1FF) card standard is the same size as an ATM card, and I can bet my Nokia Torchlight that most people reading this post have never seen one.
Cutting a Mini or Micro SIM to Nano SIM
Nowadays, it is very easy to get a Nano SIM card from any of our Mobile carriers. But in the event that you are unable to, you can use a Sim Card cutter to get your Nano Sim ready. Please don’t use razor blade or scissors o. It is very risky. Go to a business centre and get yours cut to whichever desirable size.
