Our verdict

RED by SFR suits readers in FR who want a sim only plan on 1 month terms with rolling billing and no commitment. Data does not roll over and EU roaming runs on fair use terms, so the low entry price fits light users and short stays rather than heavy data habits.

Pros and cons

Pros

  • Sim only plans, so a new line can be activated on its own without a handset in the same order.
  • Billing is rolling on 1 month terms, so a line can end without serving a long fixed period.
  • The host network is SFR, and the same provider also sells fixed lines at 2,000 Mbps with routers SFR Box 7, SFR Box 8 option, Box 5G.
  • Support runs on chat, phone and help centre, putting phone, chat, a help centre and a community board in one place.

Cons

  • Data rollover is not offered, so data left at the end of a month expires instead of carrying over.
  • EU roaming runs on fair use terms, so frequent travel across Europe is not a flat included allowance.
  • Billing is rolling only, while GETESA (prepaid and contract) and Lonestar Cell MTN (contract and prepaid) also list contract billing, so no committed term sits behind a lower monthly figure.
  • A single market: plans are sold in FR only, so there is no version of the same plan to pick up after moving abroad.

Who it suits

  • Readers in FR who pay as they go and would rather not serve a fixed minimum term
  • People who want 5G, an eSIM and hotspot sharing on one bill without a handset
  • Households after mobile and fixed lines from one provider, with fibre at 2,000 Mbps and a choice of SFR Box 7, SFR Box 8 option, Box 5G

Who should look elsewhere

  • Readers who want a contract term, since GETESA (prepaid and contract) and Lonestar Cell MTN (contract and prepaid) both list contract billing while this brand bills rolling
  • Readers whose address has weak reception on SFR, since yesss! runs on A1 instead

Core features

Plans are sim only, so there is no handset in the package and the number is ready to use on its own. 5G is available, and an eSIM can be used instead of a plastic card, which suits a traveller who would rather not wait for post. Hotspot sharing is allowed, so a laptop or tablet can share the connection when mobile data is the only route online. Roaming reaches 137 countries. The one clear gap is data rollover, which is not offered, so unused data does not carry into the next month.

The company behind it

The brand sits inside SOCIETE FRANCAISE DU RADIOTELEPHONE - SFR, the network operator that supplies the host network behind the plans, and its headquarters is in France. Support runs on chat, phone and help centre: a reader can start a chat, call an adviser, work through the help centre or post in the community. There is no store counter in that list, so anyone who prefers face to face help starts the conversation by phone instead.

Frequently asked questions

What does the entry plan cost and what comes with it?+

The entry plan is priced at €1.99 a month and runs on 1 month terms with rolling billing, and it carries a small data allowance. Larger plans sit above it, all on no commitment terms, with allowances sized for streaming and heavier use. The price list holds the full ladder to compare.

Do I have to sign a minimum term?+

No commitment is attached to any of the plans, and billing is rolling, so the arrangement can be stopped without serving a long fixed period. That is the main difference from brands such as GETESA, where billing covers prepaid and contract, and Lonestar Cell MTN, which lists contract and prepaid.

Which network do the plans run on?+

Plans are hosted on the SFR network, so reception follows that operator's coverage, and 5G is available on the mobile plans. Readers who want a different host can look at yesss!, which runs on A1 instead, and check the address before they order.

Can I use an eSIM and share data with a laptop?+

An eSIM is available, and hotspot sharing is allowed, so a tablet or laptop can share the mobile connection without a physical card being posted out. The larger plans carry the bigger allowances that suit that kind of use, and the shared traffic comes out of the same monthly bundle.

What happens to data I do not use?+

Data rollover is not offered, so anything left at the end of a month expires rather than moving into the next one. Heavy users are the ones affected, since a big allowance is only worth what the month can absorb. Readers who want unused data to count should size the plan closer to regular use.

Does the plan work abroad?+

Roaming is available across 137 countries, and travel inside Europe runs on fair use terms rather than a flat included allowance. That makes short trips straightforward, though a long stay abroad is worth checking in advance since fair use can cap heavy roaming.

Which market can I sign up in?+

The plans are sold in FR only, and the provider behind the brand is SOCIETE FRANCAISE DU RADIOTELEPHONE - SFR, registered in France. There is no second market to fall back on, so readers outside the home market would be looking at a different set of providers entirely.

How do I get help if something goes wrong?+

Support runs on chat, phone and help centre, so a reader can start a chat, call, read the help centre or post in the community. A billing or coverage question is easy to raise by phone, while anything that needs screenshots fits the chat and community routes.

Does the brand sell fixed lines as well as mobile?+

The same provider sells fixed lines over fttp, cable and 5G, with fibre reaching 2,000 Mbps for download and 1,000 Mbps for upload. Routers SFR Box 7, SFR Box 8 option, Box 5G cover the different lines, and setup fees run €0 to €29. Early termination is charged separately, under terms set out as Termination fee 59 EUR fibre/THD, 29 EUR Box 5G.
