As more and more people depend on technology to get things done, the curiosity around the latest tech trends, particularly 5G, is growing. However, 5G is still not as widespread as predicted, leaving people with more expectations than experiences.
Combine this with the abundance of online information, and you get lots of harmful advice and misinformation about 5G posted by unverified sources. We asked 5G experts to break down four myths and uncover the truth behind how 5G works. Here’s what we learned.
The first 5G devices and networks entered the market over two years ago, yet many populations don’t have access to 5G today. Is the 5G rollout that slow?
Truth: “Marketing around 5G and 5G phones created hype early and raised expectations that communications providers are still catching up to, but when you look at the technology deployment timelines, 5G is actually rolling out faster than 4G,” says Shawn Carpenter, program director, 5G & Space, for Ansys. “The U.S. has lagged many of the progressive Asian and European markets in delivering new C-band services that will enable the long-expected increased bandwidths, but 2022 will see marked progress in tower service deployments.”
You also need to consider the pandemic when analyzing the 5G timeline. The worldwide lockdowns and travel restrictions significantly affected supply chains and slowed the adoption of 5G.
Yet, despite these hindrances, more than 41 million people were subscribed to 5G mobile phone service last year, and the number is growing rapidly. “If you have a phone capable of C-band 5G service, you should see elevated service in most U.S. cities during 2022,” Carpenter said, adding that “a few 5G handset users in select downtown city locations may be able to access the new mmWave ultrawide bandwidth service at 28 GHz.”
When the Federal Aviation Administration (FAA) warned airlines that “C-Band 5G signals could interfere with some altimeters that pilots use to land in conditions with low visibility,” people started believing you can’t use 5G phones at the airport.
Truth: This myth is partly true. Networks like AT&T and Verizon have agreed to postpone their 5G expansion plans based on FAA’s guidelines. But this doesn’t mean you must keep all your 5G devices at home when hopping on an airplane.
“There are still some 5G bands that are not considered a problem and will work at the airport if the local service provider has installed the service in their base stations,” Carpenter says. He adds that the new C-band 5G service will become available on a limited basis around airport facility locations, especially within the terminals, after July so that you can use 5G or any other service like usual.
Since 5G is considered “fast,” we’ve seen rumors that it will replace Wi-Fi. Do users really have to choose between the two?
Truth: There has been talk of wireless technologies replacing Wi-Fi for years, but the answer has always been the same: Not yet, says Dan Hays, Technology, Media, and Telecommunications principal at PricewaterhouseCoopers. Both have their pros and cons, but “when you combine the capabilities of each, they become complementary, and the resulting infrastructure is optimized for all types of communication and use cases.”
Echoing this view, Tiago Rodrigues, CEO of Wireless Broadband Alliance, says: “By working together, Wi-Fi, especially the recent standards Wi-Fi 6/6E, and 5G, can support consumer and business applications ranging from augmented/virtual reality (AR/VR) to industry 4.0 smart factories.”
One example is providing reliable coverage indoors for bandwidth-intensive applications, such as 4K video cameras used for security and factory automation – something that’s challenging for 5G as the signals don’t get inside buildings very well from outside.
To sum up, neither users nor businesses must choose between 5G and Wi-Fi. It’s far better to combine the two for a more efficient network. That way, everyone wins.
Sometimes your AT&T phone may display the “5G E” signal at the top. Does this mean your old device is 5G-enabled now?
Truth: The “5G E” signal has nothing to do with an actual 5G network, as 5G E stands for 5G Evolution. “While 5G Evolution may sound like a form of 5G, it’s really a bit of marketing and is actually a name used by carriers to describe 4G LTE-A, an advanced version of the 4G LTE network standard that may offer enhanced performance,” Hays explains.
Seeing the “5G E” icon may mean you will enjoy a better network than the typical 4G LTE service. However, Carpenter says that you still need a new 5G-enabled device to access real 5G service (whenever it becomes available in your area).
Myths about 5G come in all shapes and sizes. While we addressed some basic ones here, check out our guide debunking the biggest controversies around 5G if you’re hungry for more wild theories and how experts are trying to disprove them.
Are you tired of paying for streaming services you never watch just to get a phone plan feature you actually want? T-Mobile has good news for you! The carrier is rolling out new plans, called T-Mix, in early November to replace its old Experience lineup with a build-your-own perks system called Picks.
The benefits you choose vary from streaming and gaming to food delivery, AI, satellite service, and phone discounts. But if you are satisfied with your existing plan, you can keep it.
Merely days after the iPhone Duo hit the shelves, images of broken screens on the phone started popping up across social media. Until now, it’s been unclear what’s causing the line of defective pixels that appears vertically along the crease, as well as horizontally, on the phone’s inner display.
Apple has finally acknowledged the issue, which has shown up on iPhone Duo units owned by customers as well as demo units in stores. In a statement shared with Bloomberg, Apple says that not all iPhone Duo units are affected and that those that are tend to show the display fault early on. The company added that users who experience problems with their iPhone Duo display should contact AppleCare for a replacement.
Not long ago, Apple treated independent repair like an act of outright hostility. The Cupertino giant locked down parts with serial-number pairing, while repair tools remained firmly out of reach of anyone outside its authorized repair network. More importantly, the company waged a legal and lobbying battle against right-to-repair legislation.
I've covered enough of these fights over the years to know what a shift looks like. That's why what happened in October 2026 genuinely caught me off guard. The day the iPhone Duo went on sale, what may be the most mechanically complex iPhone to date, Apple pulled off a surprising about-face. It published teardown-style repair manuals for a handful of major components.
