Best Bluetooth Calling Smartwatches Under ₹3500 in India (2026)

A few years ago, a smartwatch that could actually take calls meant spending real money. That has changed. Today you can strap a watch to your wrist that rings when your phone rings, lets you answer with a tap, and shows your messages at a glance, all for less than the cost of a decent pair of earbuds.

The tricky part isn’t finding one. It’s finding a good one. Under ₹3500 the market is crowded, and plenty of watches promise Bluetooth calling but fall short on call clarity, battery, or the app that holds everything together. This guide cuts through that. We’ll explain how calling actually works on a budget watch, what separates a reliable one from a frustrating one, and then walk through four genuinely capable smart wrist watches with Bluetooth that sit comfortably under ₹3500.

What “Bluetooth Calling” Really Means on a Smartwatch

It helps to be clear about this upfront, because it’s where most buyers get confused.

A Bluetooth calling smartwatch does not have its own SIM card or mobile network (in this price range, almost none do). Instead, it pairs with your phone over Bluetooth and borrows your phone’s connection. When a call comes in, the watch rings too. You can answer it using the tiny speaker and microphone built into the watch, while your phone stays in your pocket, your bag, or on charge across the room.

So the watch isn’t replacing your phone. It’s acting as a wireless extension of it. As long as your phone is within Bluetooth range, usually around 10 metres in open space, you can take and make calls straight from your wrist. Step too far from your phone and the calling feature simply stops working until you’re back in range.

This is exactly what people mean when they look for a smart watch for android call and text: a watch that pulls calls, contacts, and notifications off the phone and puts them on the wrist. Understanding this one limitation saves a lot of disappointment later.

What to Check Before You Buy a Bluetooth Calling Watch Under ₹3500

Not every budget calling watch is built the same. These are the things that actually decide whether you’ll enjoy using it or quietly abandon it in a drawer.

The Display

The screen is what you’ll look at dozens of times a day, so it matters more than the spec sheet suggests. Most of the watches worth buying in this bracket now use an AMOLED display rather than a basic LCD. AMOLED gives you deeper blacks, brighter colours, and text that stays readable without squinting. A larger panel, around 2 inches, also makes answering calls and reading messages far more comfortable than a cramped screen. If you prefer a smaller watch, compact AMOLED options like the HK11 Mini exist too, so size doesn’t have to mean compromise.

Call Quality: Speaker, Microphone and Bluetooth Version

This is the whole point of the watch, so don’t skip it. A good calling watch needs a clear speaker and a microphone that picks up your voice without you having to shout into your wrist. A newer Bluetooth version (5.0 and above) generally means a steadier connection and fewer dropped calls. If you can, test a call in a quiet room first; it’s the quickest way to judge whether the audio is usable day to day.

Battery Life and Charging

Calling, an always-on display, and frequent notifications all drain the battery faster. Most watches in this range are designed to last a few days on normal use, less if you’re on calls often. Many now charge wirelessly, which is convenient because there’s no fiddly port to line up, just place the watch on its charging puck.

The Companion App

Every Bluetooth calling watch pairs with a phone app that handles setup, watch faces, notifications, and health data. If the app is unstable, the whole experience suffers. Several of the watches below use the widely known WearFit Pro app. Before you commit, it’s worth checking that the app is available for your phone and that pairing is straightforward.

Phone Compatibility

A good budget watch should work with both Android and iPhone. Most do, through their companion app, though a few advanced features can behave differently on iOS than on Android. If you own an iPhone, confirm that calling and notifications are supported on your model before buying.

Build and Everyday Durability

You’ll wear this every day, through sweat, rain, and hand-washing, so basic water resistance is worth having. Ratings like IP67 or IP68 indicate protection against splashes and dust. A quick word of caution: these ratings cover everyday splashes, not swimming or diving, so don’t treat a budget calling watch as a swim watch unless the brand specifically says so.

The Best Bluetooth Calling Smartwatches Under ₹3500

Each of the watches below offers Bluetooth calling, an AMOLED display, and a price under ₹3500. They’re listed with what we can confirm about each one, who it suits best, and a link to check the current price and full details.

HK12 Pro Series 12 — The Newest All-Rounder

The HK12 Pro Series 12 Smartwatch is the latest of the lot, and it’s built around a large 2.02-inch AMOLED display that gives it a bold, premium look on the wrist. Bluetooth calling lets you make and take calls directly, while call, message, and app notifications land on the watch as they arrive.

On the health side it covers the daily basics well: step counting, heart-rate monitoring, and sleep tracking, all handled quietly in the background. You can switch between customisable watch faces to suit your outfit or mood, and it works with both Android and iOS. It comes in Black, Gold, and Silver, so there’s a finish for most tastes.

Best for: anyone who wants the newest model with a big, clean screen and a straightforward, no-fuss calling experience. Current price is around ₹3199.

HK11 Pro Max — The Highly Rated Pick

The HK11 Pro Max Smartwatch has earned a 5-star rating from buyers, which counts for a lot in a category where quality varies. It pairs an AMOLED display with Bluetooth calling and a set of AI-assisted features (marketed as its Gen-2 upgrade).

If you value a model that existing customers already rate highly, this is the safe, popular choice in the line-up. It also tends to sit at a lower price than the newest release, which makes it appealing if you want strong reviews without paying for the latest badge.

Best for: buyers who want a proven, well-reviewed watch rather than the newest one. Current price is around ₹2599–₹2799.

HK10 Pro Max Series 10 — The Feature-Packed Value Choice

If you want the most on your wrist for the money, the HK10 Pro Max Series 10 is the one to look at. Its 2.02-inch AMOLED screen runs at a smooth 144 Hz refresh rate, which makes scrolling and animations feel noticeably slicker than most budget watches.

Under the hood it carries 3.2 GB of storage and 2 GB of RAM, which supports local music playback straight from the watch, with TWS Bluetooth earbud support for listening. Health tracking is broad here, covering heart rate, blood oxygen (SpO2), blood pressure, and sleep. It charges wirelessly, carries an IP67 rating for everyday splash resistance, and works with both Android and iOS. Bluetooth calling, of course, is built in.

Best for: anyone who wants the longest feature list, local music, and a fast-feeling screen at the lowest price. Current price is around ₹2599.

HK9 Ultra 2 — The Big-Screen, Health-Focused Option

The HK9 Ultra 2 (Gen 2) stands out with the largest display in this group: a 2.12-inch AMOLED screen at 485 × 520 resolution in a square, 49mm case. It’s a watch that makes a statement on the wrist while staying practical.

It’s also the most health-oriented pick here, with a heart-rate sensor, blood oxygen, and blood pressure monitoring, plus multi-sport modes, a built-in compass, and sleep tracking. It carries an IP68 rating (the highest in this list for splash and dust resistance), runs on Bluetooth 5.2, pairs with the WearFit Pro app, and comes with a comfortable silicone strap. Bluetooth calling, a speaker, and a microphone are all included, and it’s a “Top rated” product on the store.

Best for: those who want the biggest screen and the widest set of health and fitness sensors. Current price is around ₹2699.

Quick Comparison

Here’s how the four compare on the details we can confirm. Where a spec isn’t listed, it simply means it wasn’t confirmed on the product page at the time of writing, so check the live listing for the latest.

Do These Watches Work With Both Android and iPhone?

Yes. Each of these watches is designed to pair with both Android phones and iPhones through its companion app. That makes them a flexible choice if you switch phones, or if different people in the house use different brands.

That said, it’s worth setting expectations if you’re on an iPhone. Smartwatches at this price are built primarily around the Android experience, and while calling and notifications generally work on iOS, a handful of advanced features can be more limited than on Android. If you own an iPhone and a specific feature matters to you, confirm it’s supported before buying rather than assuming.

Can You Reply to Texts From These Watches?

This is where honesty helps more than hype. If you specifically want a smart watch you can text on, it’s worth knowing that calling and texting work a little differently. On most budget Bluetooth calling watches, you can comfortably read incoming messages and app notifications on your wrist. Replying is more limited. Some models, such as the HK9 Pro Max Plus, market quick-reply support, but what actually works depends heavily on the watch’s software, the companion app, and your phone.

So if your main goal is to glance down and see who’s messaging without pulling out your phone, any of these will do that well. If full two-way texting from the wrist is essential to you, check the exact reply support on the specific model before you buy, because it varies from watch to watch even within the same price range.

Getting the Best From Bluetooth Calling

A calling watch is only as good as its setup. A few habits make a real difference:

Keep your phone in range. Calling only works while your phone is connected over Bluetooth, usually within about 10 metres. If calls drop, the first thing to check is the distance between watch and phone.

Allow notification permissions during setup. If messages or calls aren’t showing on the watch, the usual cause is a permission that wasn’t granted in the companion app. Reopen the app, check notification access, and make sure the app is allowed to run in the background.

Keep Bluetooth on and the app running. If the watch disconnects often, background-app restrictions on your phone are a common culprit. Letting the companion app stay active in the background keeps the connection stable.

Charge before heavy use. Calling and an always-on display drain the battery faster. If you know you’ll be on calls a lot, top up beforehand so it doesn’t die mid-day.

Frequently Asked Questions

Can you make calls on a Bluetooth smartwatch without carrying your phone?
No. In this price range the watch uses your phone’s connection over Bluetooth, so your phone needs to be nearby. Step out of range and calling pauses until you’re reconnected.

Can these smartwatches handle calls and texts?
Yes. All four are smart watches with call and text support, you can make and receive Bluetooth calls and see incoming messages on your wrist when connected to your phone. Full two-way texting (replying) depends on the model and its app, so check the specific watch if that matters to you.

Which of these has the biggest screen?
The HK9 Ultra 2, with a 2.12-inch AMOLED display. The HK12 Pro Series 12 and HK10 Pro Max both use 2.02-inch AMOLED screens.

Are these smartwatches waterproof?
A couple carry splash and dust resistance ratings, IP67 on the HK10 Pro Max and IP68 on the HK9 Ultra 2. These cover everyday splashes, sweat, and rain, but they are not meant for swimming or diving.

Do Bluetooth calling watches work with an iPhone?
Yes, all four pair with both Android and iPhone through their app, though some advanced features may work better on Android. iPhone users should confirm specific features before buying.

Which one should I buy?
If you want the newest model with a clean, simple experience, the HK12 Pro Series 12. For the most features and local music at the lowest price, the HK10 Pro Max. For the biggest screen and widest health tracking, the HK9 Ultra 2. For a proven, highly rated pick, the HK11 Pro Max. And if you want something even newer, the recently launched HK12 Ultra 4 is worth a look.

Final Thoughts

Bluetooth calling used to be a premium feature. Under ₹3500, it’s now something you can genuinely rely on, as long as you pick a watch with a decent screen, clear call audio, a stable app, and a build that survives daily wear. Any of the four above fits that description, each leaning towards a slightly different buyer.
