What is the Mobile World Congress
The MWC is considered to be the most relevant world fair in the mobile communication sector and where tens of thousands of people enjoy the latest technological innovations from a large number of companies.
An annual congress that allows numerous professional profiles to be up to date on everything that has to do with the most cutting-edge technological advances and highlights of the sector through lectures, conferences and demonstrations.
The institution behind the event is the GSMA, an organization that unites “more than 1,000 mobile operators and companies from across the ecosystem and related industries to promote innovation and reduce inequalities around the world”, and it is headquartered in London.
History of the GSMA
The origin of this organization dates back to 1982, when the Groupe Speciale Mobile (GSM) was formed by the European Post and Telecommunications Confederation (CEPT) “to design a pan-European mobile technology”.
The GSMA as such came into being in 1995, and began as the GSM MoU (Memorandum of Understanding) Association.
GSM World Congress, the origin of the MWC
The origin of the event is considered to be in 1987 in Brussels with the “Pan Europe Digital Cellular Radio” conference, although without the characteristics of an event as it would later develop.
The 1990 GSM World Congress in Rome already had a format more similar to the current one. During the following years the venues were itinerant (Nice, Lisbon, Athens or Berlin), and the 1995 edition was even held in Madrid.
One year later, in 1996, the GSM World Congress was established in the French city of Cannes, where it remained for ten editions until 2005. At this location the event was consolidated and attendance soared from around 2,000 attendees to 24,000.
Barcelona as the MWC venue
After leaving Cannes, in 2006 the fair settled in what still remains its location: Barcelona, specifically both the Catalan capital and the neighboring town of Hospitalet de Llobregat.
When is the MWC in Barcelona
As we have just mentioned, Barcelona has been hosting the Mobile World Congress since 2006 and always between the months of February and March, with the exception of 2021, when it was held in late June and early July due to the coronavirus pandemic.
A pandemic that had caused, for the first and only time so far, the cancellation of the event in the 2020 edition, scheduled for February 24-27 of that year.
Attendees at the MWC in Barcelona
The 2025 edition closed with more than 109,000 visitors, up from 101,00 in 2024 and 88,500 in 2023, according to data from the organisers on their own website, a figure that once again returns to the 100,000 visitors that were exceeded in previous editions.
Specifically, the record is found also in 2019 with 109,000 attendees, a figure slightly higher than the 108,000 and 107,000 that, respectively, gathered in the years of 2017 and 2018.
Back in 2015 and 2016, the numbers were approaching six digits, specifically 93,000 and 94,000 visitors.
The post-pandemic editions have had lower numbers, especially in 2021, with 20,000 attendees. This is because there were still different restrictions and limitations throughout the world, especially in Asia, one of the main sources of attendance at the event.
2022 welcomed 60,000 people, a figure that reached 88,500 in the 2023 edition.
4YFN
In parallel to the celebration of the MWC, 4YFN (Four Years From Now) celebrates 10 years as one of the reference events for the international entrepreneurial system in which technology startups, investors, corporations and even public institutions meet with the aim of generating synergies and business agreements.
As they explain on their own website, “the event not only brings together all the players you need for a winning digital startup (such as investors and corporate innovators), but also puts startups on the radar of the most powerful decision makers in the connectivity ecosystem, such as CEOs of global companies. mobile operators and cutting-edge technology companies”.
Something that “helps give commercial startups the wings they need for an impressive launch.”

The company presented itself at the MWC under the slogan ‘Leading Change Inspiring Progress’, with which it transmits the innovative spirit of the company in its search for the most cutting-edge technology to lead the digital era.
Telefónica recreated the company’s more humanist vision in a 960 square metre stand. A staging with a series of spheres that have been created and traced by hand by Valencian artisans.
The Telefónica stand showcased innovative use cases thanks to the possibilities opened up by quantum computing, the IoT, the application of Artificial Intelligence (AI) in different sectors, the possibilities offered by Open Gateway APIs, and the countless capabilities of the high connectivity of its 5G network.
Telefónica’s Ágora was once again a great meeting and knowledge centre and will feature 25 live sessions, open to all MWC visitors, with presentations, talks and demonstrations by more than 100 top executives and experts.
