📝 Discussion Summary (Click to expand)

Theme 1 – 4G’s limited future & 5G rollout doubts

"New towers aren't backwards compatible, and the bandwidth has been largely reduced." – traceroute66
"5G NSA is a kludge, it is 5G radios operating on a legacy 4G core. Inherently backwards compatible." – jeroenhd
"5G SA delivers reduced power consumption and improved latency, but it’s not backwards compatible." – jeroenhd

Theme 2 – India‑only launch & Express Chat focus

"Currently only available in India." – awestroke
"This is an odd little device… it seems you can only call other express chat users?" – kjellsbells
"The real question is why would iPhone and Android users install this app?" – collabs

Theme 3 – Retro design & small‑phone expectations

"It seems particularly similar to the short lived Microsoft Kin phones from 2010." – loosescrews
"Think of it as the front cam you need to make video calls … I think the bezels is so that the corners of the phone doesn't poke you when you keep it in your pocket (it's a small device – smaller than even feature phones)." – thisislife2
"You know it's an India focused device when the top selling point is 'Check the cricket results'." – mangecoeur
