Key Information

History

[edit]

In June 1926, the company Publicidad Turística S.A. was founded, as a subsidiary of Teléfonos de México. Its main activity was the commercialization of phone directories (white section and Yellow Section).

In September 1954, he changed his company name to that of "Professional Directories" (DIPSA), since he began to specialize in the edition of the blue directory by streets, construction directory, tourism and others. During the same year and due to the modernization of telecommunications, Teléfonos de México integrates DIPSA in the administration of Mobile Radiotelephony.

In 1981, the Secretariat of Communications and Transport (SCT) was asked for a concession to install and operate a mobile radiotelephony system known as mobile radiotelephony (telephone in the car).

In 1984, the concession was obtained to operate the mobile radiotelephony service network in Mexico City, under the name of Radiomovil DIPSA S.A de C.V.

In 1989, the Telcel brand was created, starting operations in Mexico City.

In 1996, the company launched the Amigo system, the first prepaid system in America and the world.

In 2002, Telcel implemented the GSM network and Value-Added services under the Ideas Telcel concept.

In 2008, it launched its 3G connectivity system.

For 2012 it implements its LTE, LTE Advanced and 4G-LTE Connectivity system, which allows a browsing speed of up to 5 Mbps.

In March 2016, Telcel wins the spectrum tender for the frequency band 1990-1990 MHz / 2990-2990 MHz (AWS Band).

In 2017, they presented solutions related to the Internet of Things (IoT) ecosystem.

In 2020, the 5G network is launched in closed testing mode to the public and it was expected that at the beginning of 2021.[2]

On November 6, 2023, Telcel renews its image, eliminating the characteristic icon of the phone next to its name, keeping only the latter.

Voice services

[edit]

Telcel provides services in, GSM (2G), UMTS (3G) and LTE (4G, 4.5G), including the VoLTE and VoWiFi call services. The 5G NSA network requires VoLTE for calls.

Data services

[edit]

Two-way SMS was introduced by the company in January 2002, and MMS, using GSM technology (for postpaid and prepaid customers), commenced in March 2003. Since December 2004, postpaid and prepaid customers may send and receive short messages to and from users from 35 other countries.

Telcel supplies data services in GPRS, EDGE, 3G HSPA, 3.5G HSPA+, 4G LTE and 5G.[3]

Regulatory Environment

Major Regulations

Telcel's operations in Mexico have been subject to oversight by the Federal Telecommunications Institute (IFT), an autonomous regulatory body established in 2013 to promote competition, quality, and coverage in the telecommunications sector, until its dissolution in October 2025 following the enactment of the new Federal Telecommunications and Broadcasting Law (LMTR). The IFT's dissolution, initiated through constitutional reforms and the LMTR published on July 16, 2025, transferred its powers to two new entities: the Agency for Digital Transformation and Telecommunications (ATDT), which handles technical regulation, spectrum management, and cybersecurity protocols, and the Commission for the Regulation of Telecommunications and Broadcasting (CRT), focused on economic competition and user rights. This restructuring aims to streamline regulation under a unified framework while emphasizing state involvement in digital infrastructure. The 2013 Telecommunications Reform, enacted through constitutional amendments signed on June 10, 2013, introduced asymmetric regulation targeting dominant operators like Telcel's parent company, , which held over 70% of the mobile market at the time. Key provisions mandated infrastructure sharing, such as passive elements like towers and ducts, to facilitate entry by smaller competitors, and imposed spectrum caps limiting any single entity to no more than 20% of available in any band. These measures sought to curb and foster , requiring dominant players to offer wholesale access at regulated rates. The 2025 LMTR further reshaped the regulatory landscape by allocating free spectrum bands to state-owned networks, such as those operated by the Federal Electricity Commission (CFE), to expand public coverage in underserved areas without auction processes. Additionally, the imposes cybersecurity requirements on operators, mandating compliance with federal protocols set by the ATDT for protecting critical infrastructure against threats, including data breaches and network disruptions. These provisions prioritize and state-led digital inclusion, with operators like Telcel required to integrate secure technologies and report vulnerabilities. Telcel must adhere to ongoing compliance obligations, including net neutrality enforcement established under Articles 145 and 146 of the 2014 Federal Telecommunications and Law, which prohibit blocking, throttling, or of since guidelines were issued in 2021. Furthermore, the company is required to submit annual reports to the ATDT on progress toward national coverage targets, detailing deployment in rural and urban areas to ensure universal access as mandated by the LMTR.

Controversies and Fines

Telcel, as a of , has faced ongoing antitrust scrutiny in since the 2013 telecommunications reform, which aimed to curb its dominant market position by declaring companies with over 50% as having "preponderant economic power" and subjecting them to asymmetric regulations, including obligations to divest assets or interconnect networks to foster . To avoid stricter oversight, committed in 2014 to divesting sufficient assets to reduce its mobile below 50%, a process that involved selling towers, spectrum, and other infrastructure, though critics argued the reforms did little to diminish Telcel's overall dominance, which hovered around 70% in subsequent years. In early 2020, the Instituto Federal de Telecomunicaciones (IFT) fined Telnor, a regional of serving northern Mexico, 1.3 billion pesos (approximately USD 69.7 million) for violating preponderance measures by failing to disclose infrastructure availability—such as poles and ducts—on the (SEG), hindering competitors' ability to expand coverage in underserved rural areas. Telnor challenged the fine, but a upheld it in April 2025, highlighting persistent issues with Telcel's group's compliance in facilitating broader network access. Telcel encountered further controversy in 2023 over the fairness of Mexico's planned , with industry reports indicating that high reserve prices—up to 186% above international averages—deterred competitors like and from participating, potentially leaving Telcel as the sole bidder and exacerbating its market dominance in next-generation services. The IFT had scheduled the for the second half of 2023 across key bands like 600 MHz, 1.5 GHz, and 3.3 GHz, but delays and criticisms of the pricing structure fueled disputes about anticompetitive outcomes; the was ultimately canceled in January 2025 due to insufficient interest. The most significant recent penalty came in June 2025, when the IFT imposed a fine of 1.78 billion pesos (USD 93.61 million) on Telcel for engaging in relative monopolistic practices through exclusivity agreements with convenience stores, which restricted the sale of competitors' SIM cards and limited in mobile services. Telcel denied the allegations, vowing to appeal, while the IFT also fined and distributor IMMEX 19.5 million pesos each for aiding the conduct; the case stemmed from a 2021 investigation prompted by a rival operator. Amid these challenges, Telcel and its parent company opposed elements of Mexico's 2025 Federal Law on and , arguing that the dissolution of the independent IFT in favor of executive-branch agencies like the Agencia de Transformación Digital y Telecomunicaciones (ATDT) could increase political interference and undermine competition by prioritizing state control over market dynamics. Critics echoed these concerns, warning that the —published in July 2025—might slow private investment and expansion, particularly in rural areas, while Telcel lobbied to preserve regulatory to avoid further antitrust pressures.
