When was the Mobile World Congress (MWC) 2025 held in Barcelona?

Concept: Mobile World Congress (MWC) is the mobile industry's flagship annual congress, organised by the GSMA. The MWC series runs several regional editions each year — Barcelona, Shanghai, Las Vegas and others — and the Barcelona edition is the flagship. Barcelona follows a well-established scheduling pattern: in a normal year it is a four-day Monday-to-Thursday run at the turn of February into March, hosted at the Fira Gran Via. (The one notable exception was the 2021 edition, pushed to late June by the pandemic.) Dating a recent Barcelona edition therefore means locating that late-February to early-March band, not the January consumer-electronics season and not the spring conference season.

Application: MWC25 Barcelona, the 19th edition, ran from Monday 3 March to Thursday 6 March 2025 at the Fira Gran Via in Barcelona, Spain, under the official theme "Converge. Connect. Create." The dates are therefore 3–6 March 2025.

Cross-check: the Monday-to-Thursday, end-of-February to start-of-March convention holds across the neighbouring editions as well.

• MWC Barcelona 2024 — 26–29 February 2024 (Monday to Thursday)

• MWC Barcelona 2025 — 3–6 March 2025 (Monday to Thursday)

• MWC Barcelona 2026 — 2–5 March 2026 (Monday to Thursday)

The other MWC-series editions of 2025 sit well outside this band — for example, MWC Shanghai 2025 was held on 18–20 June 2025 and MWC Las Vegas 2025 on 14–15 October 2025. So a mid-January window, a mid-February window and an early-April window match no MWC edition of 2025 at all.
