SIM CARD Description Diagram

The following picture describes the parts of SIM card and how it works in detail...

SIM : Subscriber Identity Module

This is a basic knowledge about the SIM card which u will not get in google also. And many people doesn't know this too..

So i am sharing some useful information with all members through this post ...

SIM cards are of 4 types. And are shown as follows..

H1
H2
H3
H4

H1= U will get Noraml Network on this SIM.

H2= U will get Better Network on this SIM which means Strong.

H3= U will get More Better Network on this SIM which means Stronger.

H4= Normal, Better, More Better is nothing in front of this SIM

H4 SIM probably used by Corporate offices, Army People etc.. But some comapny also provide this to normal people. Why comapany doesn't provide this SIM to all user in the sense this SIM eat more bandwidth.
