Futures of Sim Cards

Friends as we all have mobile phones and using sim cards in it.
It may be micro mini or nano sim but do u know in future you can use your mobile without sim cards because external sim cards is going to be replaced by embedded sim or e-sim cards.

Now lets talk about these sim cards-

Friends do you remember when the iphone 5 launched everywhere peoples where going to get there sim cut in nano size because in iphone 5 nano sim card was used.
Now think what is it the use of sim cards basically is just a small chip that have some storage so cant we made it embedded internally did we always need to buy that plastic material.

As we know there was a time when we store our songs, videos in different videos like audio cassettes etc now all these stuff are available through cloud similarly there was a time we wrote and send letters now we doing the same work through whatsapp or email etc.

But we know sim card is very important without it mobile is useless.
Do you know in Apple’s watch version 3 e-sim card is used but it is not first time in models of ipad e-sim card also used and infact Samsung gear S3, S2 model have e-sim cards.

So what is e-sim card?
Just think that hardware in your sim cards is directly attached to your phones and that hardware can be re-write again and again basically what your sim card stores its only store your IMSI (international mobile subscriber identity) and there are some authentication keys and sometimes you store some contacts number and nothing much so what that thing is fitted directly into the phones-
It make phones more small and sleek in size because sim card tray take some space but more important thing is if you use Airtel operator and you want to go in some other operator then you don’t need to go to the customer care once you do your authentication online IDs etc after that you will get your login ID and password and now you just need to download the app of the desired operator and just do login and then your e-sim card gets the data and services of your new operator and you will on that network so managing sim cards and saving contacts in sim cards and changing again and again headache will go.
But at present in few countries many operators had started using e-sim cards for example in Apple watch 3 there are two version one with sim card and other is e-sim card watch.
So e-sim card concept is very good now we don’t have to carry physical plastic card and if our phones get lost we don’t have to worry because we have the login ID and password so we can login in the new phone it will be very secure.
In future there will be a very big revolution in sim cards industries and everyone will have this e-sim cards mobile.
