Jio vs ISRO on WiFi, Instagram's chat-first turn, and a 90-sec security win

Here's a quiet fight that affects every Indian home's internet. Jio and Airtel want the DoT to allow high-power, outdoor use of the licence-free 6GHz WiFi band — a cheap way to blanket areas where laying fibre just isn't worth it. ISRO isn't sold: its worry is that high-power WiFi could interfere with satellite communications, so the decision is stuck. This is the unglamorous plumbing that decides whether your next router actually feels faster, or stays throttled by a spectrum turf war.

The problem

India's fast home broadband still leans heavily on fibre, which is expensive and slow to roll out across large or hard-to-reach areas. Carriers need a cheaper way to expand high-speed coverage quickly.

What changed

Jio and Bharti Airtel are pushing India's Department of Telecommunications to allow high-power, outdoor use of the licence-free 6GHz WiFi band — a low-cost way to blanket coverage where fibre isn't practical.

The catch

ISRO has flagged that high-power 6GHz WiFi could interfere with satellite communications, so the DoT's decision has stalled. Nothing is approved yet — this is a live regulatory tug-of-war, not a done deal.

What it means for you

No action needed today, but keep an eye on it: the outcome decides whether your next router taps a faster, less-congested 6GHz band or stays limited. It's the backbone of India's next-gen WiFi.

Instagram is rolling out a stack of updates: photos directly in comments so you can reply with a meme or screenshot instead of just text, video recording inside the Instants camera in your DM inbox, a new WhatsApp banner plus Business hours and Contact info on profiles, and dubbed reels in broadcast channels. None of these are headline features on their own, but stacked together Meta is clearly turning IG into a messaging-first app rather than just a feed.

The problem

Instagram's comments and DMs have stayed fairly text-first and rigid, while rivals lean into richer, more casual, chat-style messaging.

What changed

Instagram is rolling out photos directly in comments (meme and screenshot replies), video recording inside the Instants DM camera, a new WhatsApp banner plus Business hours/Contact info on profiles, and dubbed reels in broadcast channels.

The catch

These are staggered rollouts and tests, so not everyone has them yet, and individually none of them is a marquee feature — the shift only really shows when you stack them together.

What it means for you

If you post or run a page, expect comment threads to get more visual and profiles to double as contact cards — worth planning your replies and profile layout around it.

If you've got a Samsung and juggle a work plus personal number, you don't need a sketchy 'clone' app from the Play Store to run two WhatsApps. One UI has it built in: Settings > Advanced features > Dual Messenger, then toggle on WhatsApp (it works for Messenger, Telegram and more too). You get a second, fully separate copy with its own login, and you can even keep a separate contact list for it. It's genuinely one of the most underused One UI features.

The problem

Plenty of people juggle a work and a personal number and end up installing sketchy third-party 'clone' apps to run two WhatsApps — which can put your account at risk.

What changed

Samsung's One UI has Dual Messenger built in. Go to Settings > Advanced features > Dual Messenger and toggle WhatsApp (it also works for Messenger, Telegram and more) to get a fully separate second copy with its own login and optional separate contact list.

The catch

It's Samsung/One UI only, and running two active accounts uses a little more battery and storage. It won't help on non-Samsung Android phones or on iPhone.

What it means for you

If you're on a Galaxy, ditch the clone app and switch this on to keep work and personal chats cleanly separated — safely, with no third-party risk.

One setting almost nobody turns on directly blocks a common way accounts get hijacked: set a SIM PIN. If your phone or SIM is stolen, a thief can pop that SIM into another phone and start receiving your OTPs and 2FA codes. A SIM PIN stops that cold — the SIM won't work in any device without the PIN. On iPhone it's Settings > Cellular > SIM PIN; on Android it's Settings > Security > SIM card lock. One caveat: pick a PIN you'll remember, because too many wrong tries locks the SIM and you'll need the PUK from your carrier.

The problem

If your phone or SIM is stolen, a thief can move the SIM to another phone and start receiving your OTPs and 2FA codes — a common route to account takeover, especially with the recent wave of phishing and credential attacks.

What changed

Turning on a SIM PIN locks the SIM itself, so it won't work in any device without the PIN. iPhone: Settings > Cellular > SIM PIN. Android: Settings > Security > SIM card lock.

The catch

Choose a PIN you'll actually remember — too many wrong attempts locks the SIM and you'll need the PUK code from your carrier to recover it.

What it means for you

Spend 90 seconds enabling it today. It's one of the highest-value, lowest-effort protections against SIM-swap fraud.
