Donald Trump's plan to make Tiktok American may fail, thanks to this 'Chinese video call'
TikTok
Chinese scientists have reportedly achieved a global first by successfully conducting a direct
5G satellite-to-smartphone
broadband video call. According to a report in South China Morning Post (SCMP), the world's first direct 5G satellite-to-smartphone broadband video call by scientists in China. The milestone can reportedly challenge U.S. restrictions on apps like TikTok. The test, performed earlier this month using a technology demonstration satellite, highlights the potential for streaming video content directly to standard smartphones via satellite, bypassing traditional cell towers. However, experts caution that significant regulatory, technical, and practical hurdles remain.
China's rival to Elon Musk's SpaceX at hand
The demonstration, led by
China Satellite Network
Group (China SatNet), utilized the 5G Non-Terrestrial Network (NTN) standard, enabling a smartphone to connect to a satellite without specialized hardware. Liang Baojun, head of China SatNet, announced the achievement at the Xiongan BeiDou Ecosystem Cooperation Conference. 'We validated key elements of the integrated space-ground network architecture,' Liang said, though he provided no further details.
China SatNet
oversees the Guowang megaconstellation, a planned 13,000-satellite network aimed at rivaling SpaceX's Starlink.
This breakthrough could enable mobile coverage in remote areas, supporting applications in maritime, aviation, defense, emergency response, and autonomous systems. Unlike traditional networks reliant on ground-based infrastructure, satellite connectivity could deliver universal access, a growing global demand.
The development comes amid U.S. efforts to restrict Chinese-owned apps like TikTok. In April 2024, then-President Joe Biden signed a law requiring TikTok's parent company, ByteDance, to divest the platform to a non-Chinese entity by January 19, 2025, or face a U.S. ban. President Donald Trump, since returning to office, has twice delayed the deadline, with the latest set for June 19, 2025.
A 5G analyst from the International Data Corporation (IDC), speaking anonymously due to the issue's sensitivity, downplayed the immediate impact of satellite-based networks. 'Satellite operators require licenses and face strict regulations, so bypassing oversight isn't feasible,' the analyst said. 'Bandwidth limitations also make streaming large amounts of video traffic impractical.' Geostationary satellites introduce latency issues, with delays starting at 400 milliseconds, while low Earth orbit (LEO) systems like Guowang require extensive satellite deployments to ensure adequate coverage.
Possible, but not that easy
Until now, satellite-to-smartphone communication has focused on basic functions like text messaging and voice calls. In 2020, U.S.-based Lynk Global sent the world's first satellite-to-phone text message. Other key players in the sector include SpaceX, AST SpaceMobile, Samsung, MediaTek, and Thales Group.
In China, efforts to scale satellite communication are intensifying. Alongside China SatNet, the newly formed
China Spatiotemporal Information Group
(CSTI), established in May 2024, is driving integration of satellite internet, the BeiDou navigation system, and real-time data infrastructure. Comprising China SatNet, China Mobile, and defense contractor Norinco, CSTI aims to develop practical applications for logistics, energy, smart cities, disaster response, and national defense.
While China's 5G satellite breakthrough showcases its advancing space capabilities, experts say widespread adoption remains years away, limited by technical and regulatory challenges. For now, the technology underscores the growing global race to redefine connectivity—and its implications for digital sovereignty.

Elon Musk exits White House, 'poaches' top Trump aide Stephen Miller's wife Katie for private sector role
Tech billionaire Elon Musk has made his exit from the federal government, and it appears he is taking one of President Donald Trump's top aides with him. The wife of Stephen Miller , one of Trump's top aides, has reportedly left the White House to work for Elon Musk. Katie Miller is following Elon Musk from the White House back to the private sector as the tech billionaire has officially left his post in Washington, D.C. Kate Miller was working as an adviser for Musk's Department of Government Efficiency but now that the mogul's time in Washington, D.C., is up, she is working for him 'full time,' CNN reported. Sources told the network that Kate Miller has been taking the lead on communications, including arranging Musk's interviews in connection with SpaceX's Starship launch. She shared content on her X account from Musk's interviews at SpaceX's Starbase in Texas and a quote from him about how 'DOGE is a way of life, like Buddhism.' Her new duties could include booking his media appearances for Tesla and SpaceX, one source confirmed. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Mensualités: Bonne nouvelle pour les propriétaires étouffés par les crédits Bons plans propriétaires En savoir plus Undo ALSO READ: DOGE's latest action amid crackdown on federal spending days after Elon Musk quits Trump team Musk quits White House Elon Musk officially announced his departure from the White House Wednesday after his 130-day term as a special government employee came to an end this week. Kate Miller was also considered a special government employee, which enables private sector individuals to work for the government for a limited number of days per year. Live Events According to a report by WIRED, she was appointed to lead communications for DOGE under Musk prior to his transition to the White House. An official told the outlet that her connection to Elon Musk was 'central to DOGE's interactions with the rest of the White House.' They added, 'She's the key intermediary—delivering DOGE's daily messaging across the administration and handling the delivery of any sensitive or unwelcome news to Musk.' WIRED also reported that Stephen Miller and his wife, Kate Miller, were 'pivotal figures in Musk's orbit' during his time at the White House. Stephen and Kate first met in 2017 while working on some of the Trump administration's most controversial immigration policies. Kate had recently been appointed deputy press secretary at the Department of Homeland Security, while Stephen was architecting the administration's family separation policy—a move that drew widespread international criticism. Their roles eventually brought them to the U.S.–Mexico border. ALSO READ: 'Life-threatening' bacteria found in invasive tick for first time in US.

Musk's exit from the White House—with Kate Miller accompanying him—came just one day after he publicly expressed disappointment in what President Biden has referred to as his 'big beautiful bill.' The bill includes tax cuts and stricter immigration enforcement measures. Musk criticized it in an interview with CBS, calling it a 'massive spending bill' that worsens the federal deficit and 'undermines DOGE's mission.' Stephen Miller responded indirectly on X, without naming Musk, disputing the claim that the bill increases the deficit. He clarified that DOGE cuts apply to discretionary spending, such as the federal bureaucracy, and noted that under Senate budget rules, discretionary spending cannot be cut through reconciliation. 'So DOGE cuts would have to be done through a rescissions package or an appropriations bill,' he wrote.

'It's a much tougher fight than I expected,' he said. 'I knew there were issues, but trying to fix things in D.C. is definitely an uphill battle.'

Following four turbulent months—which included posing with a chainsaw, donning a cheesehead to support a losing conservative candidate in Wisconsin, and staging a Tesla car show outside the White House—Musk is now refocusing on his business ventures.

DOGE's latest action amid crackdown on federal spending days after Elon Musk quits Trump team
The Department of Government Efficiency (DOGE) deactivated 523,000 federal credit cards after a 13-week audit aimed at curbing government spending. This comes merely two days after DOGE chief Elon Musk quit the Trump administration. This initiative, launched by President Trump and led by Elon Musk, targeted non-essential expenses across 32 agencies. While supporters claim it reduces waste, critics argue it disrupts essential services, as seen with TSA's bomb-sniffing dog unit purchases. Elon Musk, the head of DOGE, has confirmed that he is stepping away from the White House, where he has served as a senior adviser to the president. Tired of too many ads? Remove Ads Tired of too many ads? Remove Ads DOGE freezes employees' credit cards Tired of too many ads? Remove Ads Two days after tech billionaire Elon Musk left the Trump administration, the Department of Government Efficiency DOGE ) has announced the cancellation of more than half a million government credit cards amid its crackdown on federal spending. In a post on X, formerly Twitter, DOGE said it had deactivated 523,000 credit cards following a 13-week cancellations include credit cards from various federal agencies—including NASA, the General Services Administration; the Office of Personnel Management; and the departments of the Treasury, Education, Interior, Commerce, Agriculture and State."After 13 weeks, the program to audit unused/unneeded credit cards across 32 agencies has resulted in ~523k de-activated cards. As a reminder, at the start of the audit, there were ~4.6M active cards/accounts - we are now expanding the program to more agencies, as there is much more work to do," the post Ryan, the founder of told Newsweek in March: "These aren't your typical consumer credit cards. We're looking at lifelines for federal agencies—cards that keep the lights on, quite literally. Need to book a last-minute flight for a critical meeting? There's a card for that. Emergency maintenance part for a military vehicle? Yep, another card. Office supplies for a research lab working on something that could change the world? You guessed it—another card."In February, Trump's executive order froze almost all agency employee credit cards, with the exception of those who used them for "disaster relief or natural disaster response benefits or operations or other critical services." Agency heads and DOGE leaders also permitted categorical and individual exemptions to some government credit card February 18, DOGE announced it was collaborating with federal agencies to streamline credit card usage and cut administrative expenses. The initiative targeted the approximately 4.6 million federal credit cards and 90 million individual transactions recorded in fiscal year 2024. Shortly afterward, President Donald Trump issued an executive order mandating a 30-day freeze on agency employee credit of DOGE's cost-cutting measures argue that they help curb waste, fraud, and abuse in government spending. However, critics contend that the reductions have disrupted federal agency operations, making it harder to purchase essential supplies and pay for critical services and this month, DOGE suspended more than half a million federal credit cards in its ongoing effort to slash government spending. The task force, led by billionaire Elon Musk and launched by President Donald Trump earlier this year, announced that credit cards from 32 federal agencies have been deactivated as part of the by executive order following Trump's return to office in January, the Department of Government Efficiency (DOGE) was charged with downsizing the federal workforce and eliminating waste. With $40 billion in annual federal spending previously routed through government-issued credit cards, DOGE launched a deactivation campaign targeting non-essential expenses that often accumulate unnoticed across March, DOGE announced it had suspended 200,000 cards across 16 agencies. That number has since more than doubled, now exceeding 500,000 deactivations across 32 agencies. However, cuts of this magnitude have already led to operational instance, when TSA's credit cards were affected in March, officials temporarily couldn't make purchases for their bomb-sniffing dog units. "Credit card purchases have been restricted for 30 days," a TSA spokesperson told Newsweek at the time, "but canine operations have not been adversely affected by this effort."Elon Musk, the head of DOGE, has confirmed that he is stepping away from the White House, where he has served as a senior adviser to the X, he said that despite his departure, which comes as the 130-day limit on his tenure as a special government employee approaches, DOGE's "mission will only strengthen over time as it becomes a way of life throughout the government."
