Frequently asked questions
What is the cheapest mobile plan in France in 2026?
For a big data plan, Lycamobile leads with 100 GB in 5G at €4.99/month (on the Bouygues network, international calls included). RED by SFR, B&YOU and Sosh sit around €12-14 for 100 GB. For light users, entry plans start at €1.49-1.99. Every plan compared here is no-commitment.
MVNO or an operator's low-cost brand: what's the difference?
Low-cost brands (Sosh = Orange, RED by SFR = SFR, B&YOU = Bouygues) are owned by the operator and run on the exact same network with the same priority. MVNOs (Lebara, Lycamobile, NRJ Mobile, Coriolis, La Poste Mobile) rent a host network — the signal is identical, but they can be deprioritised if a cell is congested. Youprice is unique: you pick the host network (Orange, SFR or Bouygues).
Is 5G included?
Usually at no extra cost, but the data threshold varies: RED by SFR and B&YOU include 5G from 100 GB, Sosh from 200 GB, Lebara and NRJ Mobile from 250 GB. Your phone must support 5G. Lower-data plans are often 4G only.
Can I keep my number and cancel easily?
Yes. Number portability is free via your RIO code (call 3179 from your current line). Every plan here is no-commitment, so you can switch or cancel online at any time with no fee — usually a 10-day notice.
