Mobile Monsters: The World’s Biggest Operators

China is home to the largest mobile market in the world with 1.86 billion mobile subscriptions at the end of June 2026. While India overtook China in terms of total population in 2023, China has retained the top spot in mobile connections, with over 700 million more subscriptions than its neighbor as of mid-2026.

The country’s largest cellco China Mobile is—unsurprisingly—the world’s biggest mobile operator, by some margin.

Let’s take a closer look at China Mobile and the other giant operators.

China Mobile’s rapid growth

Although the years of its strongest growth are long gone, China Mobile continues to add to its subscription total quarter-on-quarter.

After launching its first services in 1997, the state-backed company didn’t hit 200 million subscriptions until Q4 2004. As take-up quickened, it reached 400 million subscriptions in Q2 2008 and 600 million by Q1 2011.

Chinese Mobile Market Subscription Growth 2004-2026

Growth began to slow as the market became increasingly saturated. After China Mobile reached the 800 million milestone in Q4 2014, it took nearly another decade to hit one billion in Q2 2024. By mid-2026 it claimed 1.01 billion mobile subscriptions.

3G and 4G

China Mobile offers 3G, 4G, and 5G services alongside three domestic rivals: China Telecom, China Unicom, and the most recent market entrant, China Broadnet.

Although initially in favor of acquiring a 3G license based on W-CDMA technology, in March 2007, China Mobile instead backed the home-grown TD-SCDMA platform and started trials of the technology in April 2008. It was granted a full TD-SCDMA concession in January 2009, launching commercial services the same month.

However, using the TD-SCDMA standard for its 3G networks hamstrung the cellco’s progress. While the W-CDMA and CDMA2000 systems used by Unicom and Telecom saw widespread international adoption, the homegrown equivalent failed to catch on elsewhere, leaving China Mobile to prop up the technology’s ecosystem single-handedly.

Almost immediately after its 3G launch, China Mobile began working on its 4G solution, starting trials of TD-LTE in 2010. Learning from past mistakes, China Mobile was one of the most prominent advocates of the TD-LTE standard over alternative 4G platforms, and the cellco helped establish the Global TD-LTE Initiative to coordinate international cooperation among providers and vendors.

China Mobile finally received its TD-LTE license in early December 2013, paving the way for the launch of commercial services in 16 cities later that month. In April 2018, it was permitted to provide FDD-LTE services and the cellco refarmed frequencies in the 1800MHz band—previously used for its 2G system—for the network.

By the end of 2014, 4G subscriptions comprised 11.2% of China Mobile’s mobile accounts, growing to 63.0% two years later and 74.9% by December 2018.

5G’s strong start

As with its approach to 4G, China Mobile was highly involved in developing 5G technologies, working alongside vendors and technical standards and specifications body 3GPP from early on.

After being awarded a 5G operating license in June 2019, China Mobile was able to offer commercial services with the frequencies it was assigned in the 2.5GHz and 4.7GHz bands on a trial basis in December 2018. The cellco launched full 5G services in 50 cities on October 31, 2019.

By the end of June 2026, China Mobile’s 5G network spanned some 2.77 million 5G base stations, up from 2.60 million a year earlier, 1.94 million in June 2024 and 1.29 million as of mid-2023.

In subscription terms, China Mobile claimed 687 million active 5G network users by mid-2026, up from 599 million 12 months earlier and 514 million as of mid-2024. 5G now makes up more than two-thirds of its subscription base. 

And of course, China is the world’s biggest 5G market.

The rest of the top 20

Two of China Mobile’s domestic competitors—China Telecom and China Unicom—sit in the third and fifth positions, respectively, in a ranking of the world’s largest wireless operators. Telecom claimed 442 million subscriptions by mid-2026, ahead of Unicom with around 359 million.

Sticking with Asia, operators from India make up the other three players in the top six, with Reliance Jio’s 478 million subscriptions putting it ahead of Bharti Airtel (404 million subscriptions) and Vi (177 million).

Top 20 Largest Cellcos Worldwide, June 2026

Surrounding Telkomsel of Indonesia in the eighth spot are three cellcos from the U.S. The largest is T-Mobile (166 million subscriptions at the end of June 2026), then Verizon Wireless (147 million) and AT&T (121 million).

Latin America contributes two operators to the top 20—namely, Vivo of Brazil and Telcel of Mexico. There are also two players representing Africa: MTN Nigeria in the 12th spot and Ethio Telecom from Ethiopia in 15th.

Meanwhile, the Middle East claims one entry—Mobile Communication Company of Iran (MCI)—with Asian cellcos NTT, BSNL, GrameenPhone and Jazz rounding out the chart.

Combined, the top 20 mobile operators in the world accounted for almost half (47%) of all subscriptions globally (9.1 billion) as of mid-2026.
