I think GSM security is less relevant than ever, specially in India. More and more people are using Whatsapp and Messenger instead of voice calls. SMS is literally non-existent. Since Whatsapp is end to end encrypted, the carrier/govt simply cannot look at the contents. PS: I wonder why you'd call one of the world's largest LTE networks "obscure". Number of Jio users is probably comparable to entire population of USA.

> Jio, obscure to the western world, where Vodafone, T-mobile, Telefonica, and AT&T are fairly well known across the world. I get it’s the third largest carrier but is only serving the one country. > GSM security, is everything. Getting the metadata of who you are and where you are, and being able to capture that passively is pretty sensitive metadata, I’m sure you’d agree.
