News Airtel launches 4G services in Chennai

[DashMajor]

What is the reason for new sim card for 4g services....as for 3g old sim card is used & its just activation that is required....

Many company having their own standard even 2G sim deducts upto 3.5G.

32k or 64k sim cannot decode 4G network, u need minimum 128k sim......

I thought 128K is the memory of a SIM, and 4G detection depends on what kind of frequency one's phone detects.

For Airtel and other 4G in India one should have handset supporting 2300Mhz bandwidth

I thought 128K is the memory of a SIM, and 4G detection depends on what kind of frequency one's phone detects.

Its not only related to memory bro.....

 

[Teufel]

Its not only related to memory bro.....

I think it is related to memory only because 64K SIM can store more contacts and messages than 32K.

 

[DashMajor]

Then 128K Sim will able to store more contacts and message then 64K

 

[Devesh]

Then 128K Sim will able to store more contacts and message then 64K

Yes its store more contact but im 100% sure that u can not access 4G network on 64k sim....

So in my view its only related to memory.

 

[DashMajor]

BTW you need device to get 4G Network, I don't think sim able to block some network to come.

 

[Devesh]

I already cheked bro normal sim can not access 4G network even u put it in 4G supported set, if its happen then why service provider say, u hav to replace ur sim......

My brother already replaced his sim with 128 k for 4G services....
