In a significant stand against digital surveillance concerns, Apple Inc. has declared its intention to reject an Indian government directive requiring smartphone manufacturers to preinstall the state-developed ‘Sanchar Saathi’ application on all devices. The controversial mandate, issued confidentially to industry giants including Samsung and Xiaomi, provides a 90-day compliance window for embedding the cyber safety tool designed to track stolen phones and prevent misuse.

The Indian telecommunications ministry has characterized the measure as an essential security protocol to combat rising cyber threats, particularly addressing the proliferation of duplicated IMEI numbers that facilitate scams and network exploitation. However, privacy advocates and political opponents of Prime Minister Narendra Modi’s administration have condemned the move as governmental overreach that could potentially grant authorities unprecedented access to India’s 730 million smartphone users.

According to three industry sources familiar with Apple’s position, the technology giant plans to formally communicate its objections to New Delhi, emphasizing that such mandates contradict its global privacy standards and threaten the security integrity of its iOS ecosystem. Two sources confirmed that Apple will neither comply with the order nor pursue legal action, but will instead present its security concerns through diplomatic channels.

The development occurs amid Apple’s ongoing legal confrontation with Indian antitrust regulators regarding penalty provisions that could potentially expose the company to $38 billion in fines. While Samsung and other Android-based manufacturers reportedly continue evaluating the mandate, Apple maintains its distinctive position due to its tightly controlled App Store and proprietary software architecture—key components of its $100-billion annual services business.

India’s primary opposition party, the Congress Party, has demanded immediate revocation of the mandate, with senior leader KC Venugopal declaring on social media platform X that ‘Big Brother cannot watch us.’ The government maintains that the initiative addresses legitimate security concerns in a market with substantial second-hand device circulation, where stolen or blacklisted phones frequently reappear in commerce.

In a landmark move affecting one of the world’s largest telecommunications markets, the Indian government has mandated the compulsory pre-installation of its state-developed Sanchar Saathi application on all new smartphones. The directive, issued by India’s Department of Telecommunications, provides manufacturers a 90-day compliance window to integrate this non-removable cybersecurity tool into devices destined for the Indian market, which serves over 1.2 billion mobile subscribers.

The government justification centers on enhancing telecom cybersecurity by combating device fraud through International Mobile Equipment Identity (IMEI) verification. Officials cite India’s substantial second-hand device market as particularly vulnerable, noting that stolen or blacklisted phones with duplicate IMEI numbers frequently resurface in consumer hands. The pre-loaded application enables users to authenticate handsets, report lost or stolen devices, and identify suspected fraudulent communications.

However, digital rights organizations and cybersecurity experts have raised significant concerns about the implementation. The Internet Freedom Foundation characterizes the mandate as transforming every smartphone into ‘a vessel for state mandated software that the user cannot meaningfully refuse, control, or remove.’ Technical concerns focus on the application’s broad system permissions and its design as an immutable component within device operating systems, potentially creating surveillance vulnerabilities by bypassing standard inter-app security protocols.

Industry compliance presents additional challenges, particularly for manufacturers like Apple that historically resist third-party software mandates. While Android devices dominate India’s market (approximately 95.5% share according to Counterpoint Research), Apple’s estimated 4.5% market share represents significant leverage in negotiations. Reuters reports the technology giant intends to formally communicate its reservations to Indian authorities rather than comply with the directive.

This development places India alongside nations like Russia, which implemented similar pre-installation requirements for state-backed applications earlier this year, highlighting the growing global tension between national security objectives and digital privacy rights in telecommunications policy.

BANGKOK (AP) — The United Nations Development Program has issued a stark warning that artificial intelligence risks creating a modern-day “Great Divergence” mirroring the inequalities of the industrial revolution, unless urgent measures are taken to ensure equitable access to the technology.

According to a comprehensive report released Tuesday, while AI promises unprecedented productivity gains and technological advancement, these benefits are disproportionately flowing to wealthy nations and communities. The analysis draws historical parallels to the 19th century industrialization period when Western nations rapidly modernized while others were left behind in technological progress.

The report emphasizes that the most pressing concern isn’t merely how AI might replace human jobs, but how it will impact vulnerable populations including those struggling with basic access to electricity and internet connectivity, older citizens, and people displaced by conflict or climate disasters. These groups risk becoming “invisible” in data systems that fail to account for their unique circumstances and needs.

Despite these challenges, the UN identifies significant potential for AI to address critical development issues. The technology could revolutionize farming through improved advisory services, enable rapid medical diagnostics including X-ray analysis within seconds, enhance weather forecasting accuracy, and streamline damage assessments in disaster-prone regions.

“As a general-purpose technology, AI systems that analyze poverty, health, and disaster risks enable faster, fairer, and more transparent decisions, turning data into continuous learning and public value,” the report states.

However, the implementation of AI brings substantial environmental and security concerns. Data centers required for AI operations consume enormous amounts of electricity and water, potentially undermining climate goals by increasing carbon emissions. The technology also raises serious ethical questions regarding privacy violations, cybersecurity threats—including AI-powered hacking—and the proliferation of deepfakes that can spread misinformation or facilitate criminal activity.

The regional disparities are particularly stark across Asia-Pacific. While nations like China, Japan, South Korea and Singapore are well-positioned to capitalize on AI advancements, countries including Afghanistan, the Maldives and Myanmar lack the fundamental infrastructure, reliable power, and technical skills needed to participate in the AI revolution. Approximately one-quarter of the Asia-Pacific population remains without internet access, potentially excluding millions from digital payment systems, digital IDs, and educational opportunities essential for economic participation.

The report concludes that AI is becoming “the region’s next essential infrastructure, like power, roads, and schools,” but with both faster benefits and sharper risks. It calls for governments to implement transparent regulations, invest in digital infrastructure and education, ensure fair competition, and establish social protections to prevent vulnerable populations from being “stranded on the wrong side of an AI-driven global economy.”

The ultimate goal, according to the UN, is to democratize access to AI capabilities so that every nation and community can benefit while protecting those most vulnerable to technological disruption.

India’s telecommunications ministry has issued a sweeping directive requiring all smartphone manufacturers to pre-install the government-developed ‘Sanchar Saathi’ cybersecurity application on new devices. The mandate, announced Monday, gives device makers a 90-day compliance window and explicitly prohibits users from uninstalling the application. Additionally, the order extends to existing smartphones through mandatory software updates, significantly expanding the regulation’s reach beyond new market offerings.

The Ministry of Communications justified the measure as essential protection for India’s 1.2 billion mobile users against cyber fraud and telecommunications security threats. Official data indicates the application, launched in January, has already facilitated the recovery of over 700,000 lost devices and garnered more than 5 million downloads since its introduction.

However, digital privacy advocates have raised substantial concerns regarding user consent and potential surveillance implications. Nikhil Pahwa, founder of technology policy platform MediaNama, characterized the move as governmental ‘testing of waters’ that could pave the way for more intrusive applications. ‘Once a government app is forcibly pre-installed on our devices, what prevents future implementations that might enable surveillance?’ Pahwa questioned, emphasizing that smartphones represent personal spaces where users traditionally maintain choice over content.

The directive is anticipated to encounter significant opposition from international smartphone manufacturers, particularly U.S.-based Apple, whose established policies prohibit pre-installation of third-party applications, including those mandated by governments. This development aligns with similar initiatives observed in other nations, including Russia’s requirement for pre-installed MAX messaging service, which critics identify as possessing surveillance capabilities.
