SFR has recently taken the lead in 5G coverage in France, according to the latest nPerf barometer, published at the end of September. This achievement allows the operator to promote its most comprehensive mobile data plan: 500 GB of 5G+ data, with no long-term contract, for 24.99 euros per month. For customers who already have an SFR box, the price is reduced to 19.99 euros per month, offering a 5-euro monthly saving and 60 euros over the course of a year. This offer is currently among the most competitive on mobile plan comparison websites. The 500 GB 5G+ plan includes 500 GB of data on the SFR network in France, 100 GB in Europe and the overseas departments (DOM), and 35 GB in 70 other countries. It also provides unlimited calls and SMS from Europe and the DOM, as well as to the United States, Canada, China, and Israel. SFR TV is included, allowing users to watch live and on-demand TV channels on their smartphones, both in France and while traveling. The large data allowance means that concerns about video consumption are largely eliminated. The plan uses the SFR network, which supports 4G, 5G, and the faster 5G+ technology. According to the nPerf mobile coverage barometer for 2026, SFR has the best 5G coverage in France, with a national index of 72.78%, just ahead of Bouygues Telecom (72.34%). To use 5G+, users need a compatible smartphone and must be in a covered area. The plan is also designed for international use, allowing 100 GB of data in Europe and the DOM and 35 GB in 70 other destinations, covering 137 countries and territories. This makes it practical for staying in touch with family abroad without relying on messaging apps. The 500 GB plan is aimed at heavy users, such as those who stream high-definition videos, download large files or games, or share internet connections. For students living in shared apartments or homes with poor fiber internet, it could even serve as a primary internet solution. SFR also offers other data plans with varying amounts of data and call minutes, such as the 40 GB and 200 GB options. To keep your phone number when switching plans, you can call 3179 to get your RIO number and provide it when ordering the new plan. The new operator will then transfer your number at no cost.
