Spanish mobile operator O2 is facing increasing customer demand for truly unlimited data plans, a feature currently not offered despite a recent overhaul of its tariff structure. While O2 has focused on improving data allowances and speeds, and leveraging the network infrastructure of parent company Telefónica, subscribers are increasingly looking for a plan that eliminates data anxiety altogether.
O2 has established itself as a competitive player in the Spanish telecommunications market, offering combined packages of fiber, mobile, and television at prices lower than those of larger, established operators. The company benefits from utilizing Movistar’s network coverage, providing stability and reliability across much of the country. However, the competitive landscape is shifting, with rivals like Digi Spain aggressively pushing unlimited data offerings.
In August 2025, O2 implemented a restructuring of its entire tariff portfolio, enhancing connection speeds and mobile data allowances. Despite expectations, this update did not include the addition of an unlimited data option. Instead, customers have been resorting to sharing data allowances between lines to maximize their internet access. This workaround highlights the unmet demand for a dedicated unlimited data plan.
The desire for unlimited data is evident in direct customer feedback. A recent post on Twitter, dated , directly asked O2 if it offered unlimited data plans. O2 responded by outlining its current highest data allowances: 300 GB for mobile-only plans at €20 per month, or 375 GB bundled with 1 Gbps fiber broadband, Movistar Plus+, and Netflix for €56 per month. These options, while generous, fall short of the truly unlimited access that many users now seek.
The question of when O2 will introduce unlimited data plans remains open. The company is continuously making adjustments to its offerings, suggesting a potential future response to customer demand. Interestingly, some O2 customers have experienced limited periods of unlimited data access, but only during technical incidents affecting the fiber network. These instances were presented as temporary solutions to service disruptions, rather than a standard offering.
The rise of Digi Spain, which has rapidly become the fourth-largest operator in Spain with its aggressive pricing and unlimited data plans, is putting pressure on O2 to respond. While O2 currently excels in entertainment offerings through its inclusion of Movistar Plus+ and its 5G+ network – currently the fastest available – the lack of an unlimited data option is a notable gap in its portfolio.
O2’s current offerings, while competitive, are structured around substantial data caps. The mobile-only plan provides 300 GB of 5G+ data with unlimited calls for €20 per month. A more comprehensive package bundles 1 Gbps fiber broadband with a 375 GB mobile data allowance, unlimited calls, and access to both Movistar Plus+ and Netflix for €56 per month. These plans represent significant value, but do not address the core desire for truly unlimited data.
The demand for unlimited data stems from a changing usage landscape. As mobile devices become increasingly central to daily life, users are consuming more data than ever before through streaming, remote work, and mobile gaming. The fear of exceeding data limits and incurring additional charges – often referred to as “data anxiety” – is a significant pain point for many subscribers. Operators like Digi are capitalizing on this by offering plans that eliminate this concern.
O2 acknowledges the customer desire for unlimited data, but currently offers workarounds such as data sharing between lines. However, this is not a direct solution and requires careful management of data usage across multiple devices. The company’s response to a customer inquiry highlights the current limitations, emphasizing the available data allowances rather than addressing the possibility of an unlimited option.
