Here’s Why You May Still Need a Landline

If you’ve still have your old cordless phone, it could be the only thing keeping you connected to the world in the event of massive mobile network outages.

Massive mobile network outages can leave you stranded without one of your most critical lines of access to the world for hours. And if your smartphone can’t make phone calls, what good is it during an emergency?

An AT&T outage last year, for instance, disrupted services for more than 12 hours in many of the most populous cities in the US, while a Verizon outage caused some phones to remain stuck in SOS mode for a significant part of the day. These outages served as a reminder of the perils of relying only on mobile phones.

Perhaps it made you reconsider the role of a home device that was once standard issue but is now nearly obsolete: the landline telephone. Here’s what to consider when deciding whether to keep (or get) a landline.

Remember the landline?

Landlines are telephones that connect to specialized wiring in our homes. The iconic image is that of a rotary-dial phone — usually rented from the phone company — that either hung on the wall or sat on a counter or table, though push-button and later cordless landlines replaced many of those oldsters in the 1980s. Landline phones connect to one another through a global communication network that was built over more than a century. But as cellphones became broadly available and affordable, many people chose to drop their landlines altogether.

A 2022 survey by the US Centers for Disease Control and Prevention found that only about 29% of US adults lived in a house with a landline phone, down from more than 90% in 2004. The crossover happened 10 years ago in 2015, which was also when smartphone sales entered a boom period that reshaped the tech industry and helped turn iPhone maker Apple into one of the world’s most highly valued companies.

Ann Williams is one of the folks who hasn’t given up on their landlines yet. When asked why she keeps hers around, she describes moving to Huntsville, Alabama, after a tornado outbreak on April 27, 2011, when dozens of twisters killed at least 250 people and knocked out power for days. Although she moved there after the tornadoes, hearing about the event brought home to her the importance of always needing a phone connection.

«The weather here is so unpredictable,» she told me in an interview. But landlines have dedicated power and often work even in an outage. «We remember a day when it was absolutely necessary to have (the landline),» Williams said.

What makes landline phones more reliable

Landline phones operate on a separate infrastructure, built from copper phone lines that are inexpensive to build and rather reliable. They also don’t have the drawbacks of cellular networks, like dropped calls, poor and distorted quality or weak reception.

A key reason people keep landlines around is that they tend to work even during power outages, which is a big plus for folks whose work involves emergency services, business or health care.

Analog fax machines are also built around landline phone systems, which means most hospitals and doctors’ offices, as well as policy and law offices, need to keep a landline connection running.

The downsides of landlines

The US Federal Communications Commission is phasing out requirements for phone companies to provide landline services (called Plain Old Telephone Service) across the country. As a result, more homes and business offices are being built with Ethernet jacks rather than phone jacks.

Landline phone connections aren’t cheap, either. CNET corporate cousin AllConnect notes that AT&T’s traditional home phone plan starts at $48 per month, and you have to use the company for internet, too. CenturyLink is cheaper, starting at $30 per month, and Spectrum will charge as little as $20 per month.

And not all landlines use copper phone lines. Increasingly, companies are piggybacking their phone systems on their internet connections, a service called Voice over Internet Protocol, or VoIP. AllConnect currently tracks only three service providers offering old-style landlines: CenturyLink, Comcast Xfinity and Cox.

How to get a new landline service

If you’re ready to get set up with a landline, call the local phone company and ask about phone services. If you live in an apartment building, it’s important for you to find out where the phone junction box is. Typically, the landlord should know and if not, the local phone company should be able to find it.

Here are some follow-up questions you want to ask, and what to look for in the answers:

Are the landlines VoIP or are they POTS? Ideally, if you’re looking for security and reliability, POTS is what you want. VoIP can work, but understand that it likely relies on your internet modem and connection to work.
If VoIP, does the company have backup power systems to ensure the voice line works in a power outage? Most companies sell backup batteries that you can buy directly from them. You can use an uninterrupted power supply, perhaps from CyberPower or APC. Do note that these are different from portable power supplies. Portable power supplies do allow you to stay electronically powered on the go, but those aren’t meant to continuously monitor for power outages and then kick in as needed.
Typically, local calls are free, but dialing out of your area code costs. What’s the rate structure? Companies like AT&T have various extra fees they charge for nationwide calls, as well as for international long-distance calls. Long-distance calls in particular are usually charged per minute, and companies don’t always publish that information on their websites. Make sure you know what it’ll cost, and if it’s too much, consider using a chat app like Signal, WhatsApp, Google Meet or Apple FaceTime for your long-distance calls instead.

What should you do with a landline phone?

If you have a landline but leave it languishing, just sucking money out of your bank account each month, you aren’t alone. But there are some ways to make it more useful.

Google Voice is a popular option that gives you a new phone number acting as a central hub. When someone calls, Google Voice rings all the phones you’ve connected, whether it’s a home landline, a cellphone, a work phone or anything else.

There are other such services too, including Zoom and RingCentral, if you don’t like working with Google.

A landline phone can also connect with home security systems and medical alert sensors to help ensure that if you’re in an emergency, help will be there as soon as possible.

What to do if you can’t get a landline connected

If you’re ineligible for a landline or don’t like the service being offered, you do have more options from satellite providers. Companies such as HughesNet and SpaceX can support VoIP over their internet connections.

Phone-makers like Apple are also slowly building satellite messaging into their devices. The iPhone 14, which debuted in 2022, has a feature called Emergency SOS, which can connect with a satellite to send location data to your friends or an emergency text to authorities.

Google Rolls Out Expanded Theft Protection Features for Android Devices

The latest Android security update makes it harder for thieves to break into stolen phones, with stronger biometric requirements and smarter lockouts.

Google on Tuesday announced a significant update to its Android theft-protection arsenal, introducing new tools and settings aimed at making stolen smartphones harder for criminals to access and exploit. The updates, detailed on Google’s official security blog, build on Android’s existing protections and add both stronger defenses and more flexible user controls.

Smartphones carry your most sensitive data, from banking apps to personal photos, and losing your device to theft can quickly escalate into identity and financial fraud. To counter that threat, Google is layering multiple protective features that work before, during and after a theft.

Don’t miss any of our unbiased tech content and lab-based reviews. Add CNET as a preferred Google source.

At the center of the update is a revamped Failed Authentication Lock. Previously introduced in Android 15, this feature now gets its own toggle in Android 16 settings, letting you decide whether your phone should automatically lock itself after repeated incorrect PIN or biometric attempts. This gives you more control over how aggressively your phone defends against brute-force guessing without weakening security.

Google is also beefing up biometric security across the platform. A feature called Identity Check, originally rolled out in earlier Android versions, has been broadened to apply to all apps and services that use Android’s Biometric Prompt — the pop-up that asks for your fingerprint or face to confirm it’s really you — including third-party banking apps and password managers. This means that even if a thief somehow bypasses your lock screen, they’ll face an additional biometric barrier before accessing sensitive apps.

On the recovery side, Google improved Remote Lock, a tool that allows you to lock a lost or stolen device from a web browser by entering a verified phone number. The company added an optional security challenge to ensure only the legitimate owner can initiate a remote lock, an important safeguard against misuse.

And finally, in a notable regional rollout, Google said it is now enabling both Theft Detection Lock and Remote Lock by default on new Android device activations in Brazil, a market where phone theft rates are comparatively high. Theft Detection Lock uses on-device AI to detect sudden movements consistent with a snatch-and-run theft, automatically locking the screen to block immediate access to data.

With stolen phones often used to access bank accounts and personal data, Google says these updates are meant to keep a single theft from turning into a much bigger problem.

Scientists Are Using AI to Help Identify Dinosaur Footprints

The Dinotracker app was trained on eight major characteristics of dinosaur footprints to quickly determine the species.

An international team of researchers has devised a futuristic tool to examine the footprints left by dinosaurs in our ancient past. The AI-powered app, Dinotracker, can identify dinosaur footprints in moments.

The research comes from a joint project by the Helmholtz-Zentrum research center in Berlin and the University of Edinburgh in Scotland. The Proceedings of the National Academy of Sciences published the paper on Monday.

Identifying a dinosaur species from a footprint isn’t always easy. The footprint is hundreds of millions of years old, often preserved in layers of rock that have shifted over the eons since the track was laid.

Also, we still have a lot to learn about dinosaurs, and it’s not always clear which species left a footprint. Subjectivity or bias can come into play when identifying them, and scientists don’t always agree with the results.

Gregor Hartmann of Helmholtz-Zentrum, who led the project, told CNET that the research team sought to remove this propensity from the identification process by developing an algorithm that could be neutral.

«We bring a mathematical, unbiased point of view to the table to assist human experts in interpreting the data,» Hartmann said.

Researchers trained the algorithm on thousands of real fossil footprints, as well as millions of simulated versions that could recreate «natural distortions such as compression and shifting edges.»

How AI is being used on dinosaur tracks

The system was trained to focus on eight major characteristics of dinosaur footprints, including the width of the toes, the position of the heel, the surface area of the foot that contacted the ground and the weight distribution across the foot.

The AI tool uses these traits to compare new footprints to existing fossils, and then determines which dinosaur was most likely responsible for the footprint.

The team tested it against human expert classifications and found that the AI agreed with them 90% of the time.

Hartmann made it clear that the AI system is «unsupervised.»

«We do not use any labels (like bird, theropod, ornithopod) during training. The network has no idea about it,» Hartmann said. «Only after training, we compare how the network encodes the silhouettes and compare this with the human labels.»

Hartmann said that the hope is for Dinotracker to be used by paleontologists and that the AI tool’s data pool grows as it’s used by more experts.

Bird vs. dinosaur

Using Dinotracker, the researchers have already uncovered some intriguing possibilities on the evolution of birds. When analyzing footprints more than 200 million years old, the AI found strong similarities with the foot structures of extinct and modern birds.

The team says one possibility is that birds originated tens of millions of years earlier than we thought. But it’s also possible that early dinosaur feet just look remarkably like bird feet.

This evidence, Hartmann notes, isn’t enough to rethink the evolution of birds, since a skeleton is the «true evidence» of earlier bird existence.

«It is essential to keep in mind that over these millions of years, lots of different things can happen to these tracks, starting from the moisture level of the mud where it was created, over the substrate it was created on, up to erosion later,» he said. «All this can heavily change the shape of the fossilized track we find, and ultimately makes it too difficult to interpret footprints, which was the motivation for our study.»

Dinotracker is available for free on GitHub. It’s not in a download-and-use format, so you’ll have to know a bit about software to get it up and running.

Belkin Is Ending Support for Wemo Smart Home Devices. Here’s What That Means for You

If you own certain Belkin Wemo devices, they’ll stop working as soon as Jan. 31. Here’s what to know before it happens.

Belkin is ending support for most of its Wemo smart home devices, a move that will shut down the Wemo app and cloud services and significantly reduce the functionality of many popular smart plugs, switches and sensors.

The change takes effect at the end of January, so you have only a few days to migrate compatible devices or start planning for replacements.

You can see the full list of affected devices on Belkin’s support page. Once support ends, features that rely on the cloud — including remote access, schedules and integrations with Amazon Alexa and Google Assistant — will stop working. Those Wemo devices will no longer function as «smart» products, even if the hardware still powers on.

Since Belkin will also stop releasing firmware updates, affected devices won’t receive bug fixes or security improvements.

Belkin’s decision highlights a growing issue in the smart home world: Devices can stop being «smart» long before the hardware wears out.

Apple Home users get a limited lifeline

There is one major exception. Some Wemo devices that are compatible with Apple Home and HomeKit can continue working after the Wemo app shuts down, but only if you migrate them before the end-of-support deadline.

«Since the Wemo app will be ending, it’s very important that users switch to Apple Home/HomeKit by the end of the month,» says CNET smart home editor Tyler Lacoma. «Belkin has a long-term partnership with Apple, so for compatible devices, that transition is usually pretty simple.»

However, Lacoma warns that older Wemo products may not support Apple Home at all.

«If someone has a Wemo device that’s not on the list of Apple-compatible products, it won’t have much functionality left,» he says. «It won’t get firmware updates to fix bugs or improve security, so at that point, it makes sense to factory reset it and recycle it before the end of the month, then look for a replacement.»

Belkin has published a list of Wemo devices that support Apple HomeKit, and users need to complete the setup process before the Wemo app is retired. The following products will continue to work through Apple HomeKit:

Wemo Smart Light Switch 3-Way (WLS0403, WLS0503)
Wemo Wi-Fi Smart Light Switch with Dimmer (WDS060)
Wemo Smart Light Switch (WLS040)
Wemo HomeKit Bridge (F7C064)
Wemo Dimmer Light Switch (F7C059)
Wemo Mini Plugin Switch (F7C063)
Wemo Outdoor Plug (WSP090)
Wemo Mini Smart Plug (WSP080)
Wemo Stage Smart Scene Controller (WSC010)
Wemo Smart Plug with Thread (WSP100)
Wemo Smart Video Doorbell (WDC010)

What about refunds?

Belkin says customers with Wemo devices that are still under warranty when support ends may be eligible for a partial refund. You can find the warranty period for each device in the list of devices on Belkin’s support page linked above. Refund requests won’t be processed until after the end-of-support date, and eligibility will depend on the product and purchase date.

Because many Wemo products were released years ago, most people should not expect to qualify for a refund. We’ve reached out to Belkin to ask whether other products will lose support in the near future. We haven’t heard back at the time of publishing.

What Wemo owners should do now

If you own Wemo devices, the clock is ticking. Here’s what to do next:

Check whether your Wemo products support Apple Home and migrate them as soon as possible.
If your devices don’t support Apple Home, plan to replace them before support ends.
Consider recycling unsupported devices once they lose smart functionality.
Remove the Wemo app after services shut down to avoid confusion.

If you’re shopping for replacements, this is a good time to look at CNET’s list of the best smart plugs and review our guide on what to do when smart home devices lose support.
