You are a very VERY lucky person! You are getting the max possible performance out of MTNL. For most it is far less than what you are getting.
 
its not always that i get that speed but yes i have experience this speed 2 to 3 times a day nut most of the time it is 2mbps
 
there are old sim cards and new one when u got the sim if its 3 years back it have large chip

----------

new chips are used for iPhone 4 after cutting them the copper area in the new sim cards are small compared to old simcard what speed u get???

----------

there is the diffrence between the copper filing of the simcard there is no size deffrence of the simcard

Sim Card used in Ipad or Iphone or Tab is called Mirco Sim. You are right architecture and design of Sim Circuitary is same is both the Sim Cards. Now that all operators had started manufacturing separate Micro Sim Card but in its absence , Nornal Sim card can be cut and resized :)
 
He is talking about the copper present at the back of SIM cards, Older one's have a lot more copper.

Would that make any difference? Isn't it the mobile (or dongle) that is supposed the 'catch' the signal? Or will the copper on the SIM make any difference?
 
I can provide 5 different Sim cards with different architecture, but does that make any difference ? This circuitary keep on changing year after year . What matters is the Sim Slot and size of Sim .
 
As far as I'm aware, there wouldn't be a difference in performance
