Stop Saving Random Numbers! Here’s How To Chat On WhatsApp Without Saving Contacts

We’ve all been there when you just need to send a quick message to someone, maybe a delivery guy, a shop, a cab driver, or a one-time work contact. But saving their number forever in your phone book? Not really required. Thankfully, WhatsApp gives you a few easy ways to message someone without adding them to your contacts.

Here’s what to do: Also Read: WhatsApp Is Set To Get Third-Party Chats Support Soon: Report First of all, open your browser (Chrome / Safari) After that, simply type this in the URL bar – https://wa.me/phone-number Replace phone-number with the full mobile number along with the country code. For example, for an Indian number: https://wa.me/91XXXXXXXXXX Now tap Continue to Chat, and WhatsApp will open directly with that number. This is the easiest universal method and works on Android, iPhone, and even WhatsApp Web. How To Use WhatsApp’s “New Chat” Shortcut on Android If you’re on Android, WhatsApp gives a small hidden shortcut. Here’s how: Open WhatsApp. Tap the New Chat button. In some versions, you’ll see an option like Message a number or Send message to an unsaved number. Enter the number and then tap Open Chat. After that, simply tap done. Apart from these, there is even another simple trick. If you use the Google Phone app, then simply head to the app, type the number you want to contact and then you’ll see a small WhatsApp icon next to the call button. Simply tap it, and the WhatsApp chat opens instantly. Many people don’t realise this shortcut exists – but it works great if you often message unknown numbers. Even Your Siri or Google Assistant Can Make A Message! Yes, your voice assistant can open a WhatsApp chat without saving the number. Try saying: “Hey Siri, send a WhatsApp message to +91 XXXXX XXXXX.” “Ok Google, send a WhatsApp message to +91 XXXXX XXXXX.” It will directly open a chat window so you can type or dictate your message.

Apple Watch Ultra 3 And Watch Series 11 Are Now 3D-Printed: Here’s What It Means For You

Apple has finally done something that the tech industry has been trying to crack for years – using 3D printing not just for prototypes, but for mass production. And the company is doing it at scale, with recycled titanium, for two of its newest wearables: the Apple Watch Ultra 3 and the titanium Apple Watch Series 11.

And according to Apple, this shift cuts raw material use by nearly half. Also Read: Tim Cook to Step Down as Apple CEO in 2026? Here’s Who Might Replace Him Why Apple Turned To 3D Printing Inside Apple, the idea didn’t start as a polished plan – more like a bold question: Could 3D printing replace traditional metal machining for premium devices? Once the question was asked, teams across product design, materials science, and environmental engineering apparently jumped in with rapid prototyping and testing. Apple wanted these cases to look and feel exactly like the forged versions – the polished mirror finish on Series 11, the rugged durability of Ultra 3, the lightweight feel, everything. And all of that had to happen while sticking to Apple’s big sustainability target: Apple 2030, which aims to make the company carbon neutral across its entire footprint by the end of the decade. How the New Process Works Traditionally, metal watch cases are forged and then carved down – which means a lot of titanium gets shaved off and wasted. With 3D printing (or additive manufacturing), Apple builds the case layer by layer, more than 900 times, until it’s nearly the exact final shape. Even the titanium powder itself had to be engineered. Each particle is around 50 microns, and its oxygen levels must be tightly controlled so it doesn’t behave unpredictably when hit by a laser. Apple describes this as a massive materials-science challenge. Once a batch is printed, the cases go through multiple steps – depowdering, slicing them apart with a heated wire, precision inspections, and then the usual assembly and stress testing. Apple even used 3D printing to improve tiny internal textures, allowing better waterproofing for antenna housings. The result? Over 400 metric tons of raw titanium were saved this year alone. But the question is, how will it impact you? With Apple now mass-producing premium parts through 3D printing, the door opens for even more design flexibility in future devices. In fact, Apple says it has already used the same recycled titanium powder for the 3D-printed USB-C port enclosure in the new iPhone Air. And from the way Apple is describing this shift, it’s clear this isn’t a one-off experiment. This is Apple quietly rewriting how its products – and maybe the industry – will be built in the future.
