Data plan details

The B&YOU Voyage plan from Bouygues Telecom provides mobile users in Metropolitan France with a 200 GB data allowance, of which 40 GB can be used in over 160 international destinations, including Europe, the DOM, Switzerland, Morocco, and the United States. The plan costs 15.99 euros per month without any commitment and includes unlimited calls and SMS within Metropolitan France and the DOM.

International usage rules

From Europe and the DOM, users can make unlimited calls and send SMS to Metropolitan France, Europe, and the DOM. The 40 GB of international data is included in the overall 200 GB monthly allowance and is not an extra data volume. This makes the plan suitable for both short trips and longer stays abroad.

Data consumption comparison

The 200 GB monthly allowance in France is more than ten times the average monthly data consumption of 19.3 GB per user in Metropolitan France, according to Arcep data from the second quarter of 2026. The plan also includes occasional tethering of a computer and access to Bouygues Telecom’s 5G network, which was ranked number 1 for mobile internet in Metropolitan France in 2025 by the nPerf barometer.

Discounts and additional costs

New customers who also subscribe to the B&YOU Pure Fibre fibre offer receive a 3-euro monthly discount for the first year, reducing the cost of the B&YOU Voyage plan to 12.99 euros per month. However, upon subscription, users are charged 1 euro for the SIM card and 1 euro for activation fees.
