Idea cellular is sending texts announcing the launch of 4G services and I'm willing to give them a try (before the big daddy Reliance Jionet sets its foot). The latest text says that you should get a 4G enabled SIM card and I'm wondering if there's any way to identify a 4G SIM via visual inspection or by dialing any code.

My phone is 4G capable and I want to know if I need to go to Idea cellular outlet to check if the SIM in my phone is already 4G ready? Looking forward to your responses.

And is there any better way than asking customer care? 😁
@Kaustubh Katdare • 27 Feb, 2016 Thanks @sharfudeen . This is the image that explains it all :


Gotta check this on my phone, will do it shortly.
@lal • 28 Feb, 2016 Any Idea which band shall be used by Idea to launch its 4G services? Heard not all phones support all bands. Especially the 850MHz band.

IIRC, Airtel is launching 4G pan India in the 1800MHz and 2300MHz bands and those are supported by almost all phones.
@Kaustubh Katdare • 02 Mar, 2016 Update: Just found out that I've the latest nano-SIM from IDEA and it seems to be of the 200 series; which means it's a 3G SIM.

Gotta go and check with the idea cellular folks whether they have the new 4G SIM cards available 😀
@Kaustubh Katdare • 11 Jul, 2017 Quick question: Is the naming convention for 4G and 3G cards followed everywhere in the world? Or is it India specific?

Quick answer: 😁 I think every country having the same convention as us for the cards. I found this: 2G / 3G / 4G coverage in India - nPerf , just check out. If there have separate network (2G, 3G, 4G, in the sense) means, there might be separate cards. But i'm sure about this. I may ask my abroad friends and will update it asap.

Just check out the back of your current sim card, it will either say 3G or 4G, and even if it says 3G you can still get 4G using a 3G sim card.

The best way I suggest is insert the sim into your phone and check.
