BARCELONA — British telecommunications giant BT says it expects to launch its first so-called “standalone 5G” network in 2024.
Howard Watson, BT’s chief technology officer, told CNBC that the telco group plans to switch on its standalone 5G network, which is often referred to in the industry as “true” 5G, later this year.
“Others are talking about it. They’re talking about it. But we are working to get the right ecosystem in place, which means the right set of devices,” Watson said in an interview with CNBC at the Mobile World Congress tech trade show in Barcelona.
That comes after a trial the company conducted with Swedish telco infrastructure firm Ericsson and chipmaking giant Qualcomm demonstrating network “slicing.” Network slicing is a configuration that allows multiple networks to be created on the same common physical network infrastructure.
“We’ve already been ensuring that the SIM cards that our customers have in their current 5G devices can do 5G standalone,” Watson added. “And so once we think there’s enough critical mass to have a real proposition, with some slicing behind it as well, we will launch that, and that will be later this year.”
What ‘5G standalone’ means
5G standalone would give you a slice of the network, or a specific amount of bandwidth with certain latency commitment. Each network slice is effectively an isolated part of the network that’s designed to fulfil the requirements requested by a certain application.
So, for example, if you’re a gamer and you need super-low latency to play a game competitively online, you could use 5G standalone to get latency of nine to 10 milliseconds, close to what you get from an HTTP connection to your home.
Latency is important for gamers as it measures response delays. The higher the latency, the more lag you get when you’re playing a game. This means less smooth gameplay.
“You may not want that 24 hours, seven days a week,” Watson said. “So we might have a really flexible pricing mechanism that says you can have that from 6pm to 8pm.”
“So bringing it to life in propositions for customers is how we will market it rather than with, come and buy some ‘standalone.'”
Milind Kulkarni, vice president and head of InterDigital’s wireless labs, said that network slicing is one step in a number of technological upgrades that will lead to so-called “5G Advanced,” an evolution of the 5G network.
“5G offers a fantastic platform with a lot of capability to support many use cases, and we have to continue our focus in enabling more vertical markets and increasing its capabilities as we march through 5G Advanced,” Kulkarni told CNBC.
5G standalone is different from 5G Advanced, though. 5G standalone refers to the development of a 5G network that isn’t being built on top of 4G cores. Whereas 5G Advanced is a complete evolution of the network.
BT and other network operators are looking to 5G standalone as a way to make more money from the next-generation networks they first started deploying around five years ago.
Future of 5G
Naturally, 5G plans are more expensive than 4G.
But consumers have been struggling to understand the value of 5G — which is often only incrementally faster than 4G — when many regions of the U.K. and developed countries still lack 5G connectivity.
To get 5G standalone networks off the ground, network operators first need smartphone makers like Apple and Samsung to ensure their devices have standalone capabilities.
Apple hasn’t done that in Europe, Watson said, and he’s holding out to see what happens with the next iPhone to see if the tech giant will make its smartphones 5G standalone-ready.
BT’s consumer business had a major rebrand in 2023, which focused on the launch of a full suite of services, an area that telco companies have had less success scaling than digital giants such as Meta, Google, Apple and Amazon.
BT is the U.K.’s leading telecom company, operating fixed and wireless networks across the country. BT’s consumer division has roughly 30% market share in broadband and mobile services.
Its enterprise segment works with larger business customers.
It has been operating the EE mobile network since acquiring it for £12.5 billion in 2016.

The House Committee on Energy and Commerce is investigating 23andMe‘s decision to file for Chapter 11 bankruptcy protection and has expressed concern that its sensitive genetic data is “at risk of being compromised,” CNBC has learned.
Rep. Brett Guthrie, R-Ky., Rep. Gus Bilirakis, R-Fla., and Rep. Gary Palmer, R.-Ala., sent a letter to 23andMe’s interim CEO Joe Selsavage on Thursday requesting answers to a series of questions about its data and privacy practices by May 1.
The congressmen are the latest government officials to raise concerns about 23andMe’s commitment to data security, as the House Committee on Oversight and Government Reform and the Federal Trade Commission have sent the company similar letters in recent weeks.
23andMe exploded into the mainstream with its at-home DNA testing kits that gave customers insight into their family histories and genetic profiles. The company was once valued at a peak of $6 billion, but has since struggled to generate recurring revenue and establish a lucrative research and therapeutics businesses.
After filing for bankruptcy in in Missouri federal court in March, 23andMe’s assets, including its vast genetic database, are up for sale.
“With the lack of a federal comprehensive data privacy and security law, we write to express our great concern about the safety of Americans’ most sensitive personal information,” Guthrie, Bilirakis and Palmer wrote in the letter.
23andMe did not immediately respond to CNBC’s request for comment.

23andMe has been inundated with privacy concerns in recent years after hackers accessed the information of nearly 7 million customers in 2023.
DNA data is particularly sensitive because each person’s sequence is unique, meaning it can never be fully anonymized, according to the National Human Genome Research Institute. If genetic data falls into the hands of bad actors, it could be used to facilitate identity theft, insurance fraud and other crimes.
The House Committee on Energy and Commerce has jurisdiction over issues involving data privacy. Guthrie serves as the chairman of the committee, Palmer serves as the chairman of the Subcommittee on Oversight and Investigations and Bilirakis serves as the chairman of the Subcommittee on Commerce, Manufacturing and Trade.
The congressmen said that while Americans’ health information is protected under legislation like the Health Insurance Portability and Accountability Act, or HIPAA, direct-to-consumer companies like 23andMe are typically not covered under that law. They said they feel “great concern” about the safety of the company’s customer data, especially given the uncertainty around the sale process.
23andMe has repeatedly said it will not change how it manages or protects consumer data throughout the transaction. Similarly, in a March release, the company said all potential buyers must agree to comply with its privacy policy and applicable law.
“To constitute a qualified bid, potential buyers must, among other requirements, agree to comply with 23andMe’s consumer privacy policy and all applicable laws with respect to the treatment of customer data,” 23andMe said in the release.
23andMe customers can still delete their account and accompanying data through the company’s website. But Guthrie, Bilirakis and Palmer said there are reports that some users have had trouble doing so.
“Regardless of whether the company changes ownership, we want to ensure that customer access and deletion requests are being honored by 23andMe,” the congressmen wrote.

“TSMC is not engaged in any discussion with other companies regarding any joint venture, technology licensing or technology,” CEO C.C. Wei said on the company’s first-quarter earnings call on Wednesday, dispelling rumors about a collaboration with Intel.
Intel and TSMC were said to have been looking to form a JV as recently as this month. On April 3, The Information reported that the two firms discussed a preliminary agreement to form a tie-up to operate Intel’s chip factories with TSMC owning a 21% stake.
Intel was not immediately available for comment when contacted by CNBC on Wei’s comments on Thursday. The company previously said it doesn’t comment on rumors, when asked by CNBC about the reported discussions.
TSMC’s denial of tie-up talks with Intel comes as President Donald Trump is pushing to address global trade imbalances and reshore manufacturing in the U.S. through tariffs. The Department of Commerce recently kicked off an investigation into semiconductor imports — a move that could result in new tariffs for the chip industry.
TSMC reported a profit beatfor the first quarter thanks to a continued surge in demand for AI chips. However, the company contends with potential headwinds from Trump’s tariffs — which target Taiwan — and stricter export controls on TSMC clients Nvidia and AMD.
A motorcycle is seen near a building of the Taiwan Semiconductor Manufacturing Company (TSMC), which is a Taiwanese multinational semiconductor contract manufacturing and design company, in Hsinchu, Taiwan, on April 16, 2025.
Here are TSMC’s first-quarter results versus LSEG consensus estimates:
Revenue: $839.25 billion New Taiwan dollars, vs. NT$835.13 billion expected
Net income: NT$361.56 billion, vs. NT$354.14 billion
TSMC’s reported net income increased 60.3% from a year ago to NT$361.56 billion, while net revenue in the March quarter rose 41.6% from a year earlier to NT$839.25 billion.
The world’s largest contract chip manufacturer has benefited from the AI boom as it produces advanced processors for clients such American chip designer Nvidia.
However, the company faces headwinds from the trade policy of U.S. President Donald Trump, who has placed broad trade tariffs on Taiwan and stricter export controls on TSMC clients Nvidia and AMD.
Semiconductor export controls could also be expanded next month under the “AI diffusion rules” first proposed by the Biden administration, further restricting the sales of chipmakers that use TSMC foundries.
Taiwan currently faces a blanket 10% tariff from the Trump administration and that could rise to 32% after the President’s 90-day pause of his “reciprocal tariffs” ends unless it reaches a deal with the U.S.
As part of efforts to diversify its supply chains, TSMC has been investing billions in overseas facilities, though the lion’s share of its manufacturing remains in Taiwan.
In an apparent response to Trump’s trade policy, TSMC last month announced plans to invest an additional $100 billion in the U.S. on top of the $65 billion it has committed to three plants in the U.S.
On Monday, AMD said it would soon manufacture processor chips at one of the new Arizona-based TSMC facilities, marking the first time that its chips will be manufactured in the U.S.
The same day, Nvidia announced that it has already started production of its Blackwell chips at TSMC’s Arizona plants. It plans to produce up to half a trillion dollars of AI infrastructure in the U.S. over the next four years through partners, including TSMC.
Taiwan-listed shares of TSMC were down about 0.4%. Shares have lost about 20% so far this year.
