Cdiscount Mobile is currently offering a special 200 GB 5G mobile plan during the French Days event, priced at 12.99 euros per month with no contract commitment. The deal includes a 50 euro gift card for use on the Cdiscount online store, which can be redeemed on purchases of at least 50 euros. This offer is available to anyone who subscribes during the promotional period and is powered by the Bouygues Telecom network. According to the nPerf 2025 barometer, which was released in January 2026, Bouygues Telecom holds the top position with 95,684 nPoints, a measure of network performance. The 200 GB 5G plan provides unlimited voice calls, SMS, and MMS in France, Europe, and the DOM (Departments and Overseas Territories). It also includes 35 GB of additional 4G data that can be used from 164 international destinations without affecting the 200 GB 5G allowance in France. Based on data from ARCEP, the average monthly mobile data usage is around 18.3 GB, making this 200 GB plan significantly more generous than the typical user’s needs. The SIM card required for the plan costs just 1 euro. The promotional offer can be accessed directly through the Cdiscount Mobile website. Existing phone numbers can be transferred by calling a free number (3179) to obtain a RIO number, which must be provided during the subscription process. The new operator will then handle the number transfer at no extra cost. The French Days event, which runs until September 14, 2026, features a wide range of technology deals from various retailers.
