NRJ Mobile VS Cdiscount Mobile: which offer 10 GB choose in 2025?

Very close packages … apparently only

10 GB of mobile internet in 4G, Unlimited calls/SMS/MMSuse in mainland France, in the EU and the French overseas departments, all without obligation. At first glance, the only notable difference seems to be the price: € 5.99 at NRJ Mobile, € 4.99 at Cdiscount Mobile. A small economy, of course, but sufficient to go for a look at what is behind each offer.

On the Cdiscount Mobile side, we take advantage of the Bouygues Telecom network, recognized for its good national coverage (99 % of the population) and correct flows on a large part of the territory. The SIM card is invoiced for € 1, and we benefit from an additional 10 GB from the EU and the DOM, a total of 20 GB in all, distributed according to the areas.

NRJ mobile, for its part, is also based on a solid network (generally that of BouyguesSometimes Orange depending on the configurations). The offer takes up the same formula: 10 GB in France, additional 10 GB in Europe/DOM, reduced flow beyond without additional cost which avoids unpleasant surprises. Again, the SIM card is offered at € 1 unless a mobile is purchased at the same time, in which case it can be offered.

But beyond the figures, it is the management conditions, the flexibility of use and the related services that can make the difference.

Online management, network quality and daily use

On the user experience, Mobile NRJ highlights a 100 % online interface, with a rather fluid and accessible customer area, which can seduce the most independent. Options management, consumption monitoring or supply changes are easily made. And the brand ensures that it does not apply hidden costs: the flow is simply reduced once the quota has reached, without invoicing in addition, a reassuring detail if we often borders on the limit of the 10 GB.

Cdiscount Mobilefor its part, focusing on a quick subscription, also online, and a relatively reactive customer service. The procedures are clear, the change of number or the conservation via the Rio is without particular problems, and the package remains customizable according to its needs (adding data, occasional options, etc.).

On the network side, difficult to decide strictly. The two offers are mainly based on the Bouygues Telecom infrastructure, which guarantees stable coverage in the majority of French municipalities. For moderate use (emails, navigation, light streaming) the 10 GB monthly are more than enough, even with a little punctual connection sharing.

The important thing is above all to check, before subscribing, the quality of the signal in its life area, for example by consulting the coverage cards available on the sites of operators.

Verdict: everyone has their own criterion of choice

In the end, the two 10 GB packages are very competitive, well thought out for users looking for a cheap mobile subscription, without surplus, and capable of holding a full month without stress. Cdiscount Mobile has the advantage of the lowest price, at € 4.99/month, which can tip the scale if the budget is tight.

On the other hand, NRJ Mobile seduces by clearer customer management, a little more transparent communication on the conditions of use, and appreciable flexibility for those who want an experience without taking the head, even on the move abroad.

In any case, the two formulas remain without obligation, which means that we can test a few weeks … then change your mind without cost if necessary. A welcome freedom of movement, especially for this type of small package, often chosen as a secondary line or for a teenager, a parent, even temporary use.
In short, less than € 6 per month, this is a good plan, whatever the chosen SIM card.
