Our verdict

Coriolis is an MVNO selling sim only plans on the SFR network, which suits anyone who wants generous data without tying up money in a long contract. Le Basic starts at €7.99 a month, all of its sim only plans carry no commitment, and 5G, wifi calling and hotspot sharing come as standard.

Pros and cons

Pros

  • Sim only plans are sold without a commitment, with contract terms of 1 and 24 on offer for anyone who prefers a longer term.
  • Le Basic is priced at €7.99 a month, and the tiers above it add data rather than folding a handset into the bill.
  • 5G, wifi calling and hotspot sharing sit inside the plan price instead of being sold as paid extras.
  • Support runs through email, chat and phone, so help is reachable by phone as well as in writing.

Cons

  • On entry price Coriolis ranks 142 of 258 brands, so cheaper sim only options sit elsewhere on the shortlist.
  • Coverage follows the host network: as an MVNO (mvno) on SFR, there is no network of its own to switch to.
  • The plans run in a single market, FR, so anyone based outside France is not served.
  • Roaming in the EU is fair use, so heavy use abroad is shaped by fair-use conditions rather than included outright.

Who it suits

  • Anyone in France who wants a generous data allowance on a sim only line and would rather not sit through a long minimum term.
  • People who want wifi calling and hotspot sharing inside the monthly price rather than paying for them separately.
  • Readers who are comfortable with an MVNO on SFR and a short list of plans instead of a large catalogue.

Who should look elsewhere

  • Buyers who want the network and the plan from one provider, since GETESA is a network seller type (network) while Coriolis resells SFR.
  • People based outside France, since Coriolis runs in a single market, FR, where Lonestar Cell MTN and yesss! cover other ground.

What it does well

Coriolis keeps the sim only package honest about what it costs, because there is no handset inside the monthly bill and nothing to amortise. 5G, wifi calling and hotspot sharing are part of the plan rather than extras sold on top, which covers the three features other sellers most often treat as add-ons. Listings across the site normally carry wifi calling (98.2%) and hotspot sharing (98.1%), and sim only accounts for 99.5% of what is listed, so Coriolis matches the norm and takes the handset out of the equation. The saving here comes from what is left out of the plan, not from what is missing inside it.

Who runs it

Coriolis is a French provider operated by CORIOLIS SAS, headquartered in France. It sells as an MVNO (mvno), so the network underneath is SFR rather than infrastructure of its own. Support runs through email, chat and phone, covering phone, chat, email and a help centre, with a human channel on the list rather than a ticket queue alone. Phone support sits at 81.5% across the site, so a named legal entity, a named host network and a reachable support desk are the parts a cautious reader can check before signing up.

Frequently asked questions

How much does a Coriolis sim only plan cost?+

Le Basic is the entry plan at €7.99 a month. Le Connecte and Le Premium sit above it, each adding data while keeping the same no-commitment terms. Nothing in the sim only range is sold with a long minimum term, so the price the line starts on is the price it keeps.

Do Coriolis plans come with a contract?+

Contract terms run 1 and 24, so there is a short option and a longer one, and billing covers both contract and rolling lines. The sim only plans themselves are all sold without a commitment, which is the simplest way to keep the monthly figure fixed and the exit cheap.

Which network does Coriolis run on?+

Coriolis is an MVNO (mvno) and runs on SFR. Coverage follows the host network rather than a network of its own, and network-level features such as 5G, wifi calling and hotspot sharing arrive through the host. Anyone comparing network sellers will see a different arrangement here.

Where can a Coriolis plan be used?+

The plans are offered in FR only, and the company is headquartered in France. No wider footprint is listed, so readers living outside France are outside the target market. Travelling abroad is a separate question, since roaming in the EU is fair use rather than a fully included allowance.

How do I reach Coriolis support?+

Support runs through email, chat and phone, which covers phone, chat, email and a help centre. A phone line matters for billing or coverage problems, where an answer in writing takes longer to arrive. Readers who prefer written contact still find chat and email on the same list.

Does the Coriolis plan include a phone?+

Sim only is confirmed, so no handset is included and the monthly figure is the whole cost of the line. That is the main saving against plans that bundle a device. If a new phone is needed as well, the combined cost sits well above the entry price of €7.99.

Is EU roaming included with Coriolis?+

Roaming in the EU is fair use, so usage abroad sits under fair-use conditions rather than a fully included allowance. Heavy data use while travelling can be shaped by those conditions. Anyone whose main draw is roaming should read the fair-use terms before picking a plan.

Where does Coriolis sit on price?+

On entry price, Coriolis ranks 142 of 258 brands, so it sits in the middle of the field. The shortlist median entry price is €6.99. The compensating factor is that the sim only plans carry no commitment, so a modest headline figure is not tied to a long term.
