The no-contract cell phone plan has changed the way the French use their mobile lines: no more waiting twelve or twenty-four months to switch carriers, and no more paying steep early-termination fees. The question now is how to choose one correctly and which pitfalls to watch out for, because “no contract” doesn't always mean “no surprises.”
What Is a No-Contract Cell Phone Plan?
A no-contract cell phone plan is a mobile subscription that can be canceled at any time, without a long notice period or an early-termination fee: a simple letter or an online request is enough, generally with no more than a one-month notice period. It's the opposite of a plan with a 12- or 24-month contract, where leaving early can be costly. Established carriers now offer their own brands dedicated to this type of plan: that's the case, for example, with the no contract phone plan sold by Boost Mobile, a low-cost carrier brand, which is often mentioned in comparisons alongside offers from mobile virtual network operators (MVNOs).
Why These Plans Are Booming
The trend is clear: no-contract plans now account for the vast majority of cell phone plans subscribed to in France, according to the electronic communications market survey published by Arcep, France's telecom regulator. Competition between established carriers and MVNOs has driven prices down in this segment, with generous data plans available for just a few euros a month.
Criteria to Compare Before Signing Up
- The data allowance that's actually useful for your needs (streaming, browsing, mobile hotspot) rather than the plan that looks most generous on paper.
- Network coverage in the areas you frequent: an MVNO uses an established carrier's network, but sometimes with limited access to 4G/5G.
- Use abroad: check the data allowance included for roaming in Europe and France's overseas territories before you travel.
- Customer service and genuinely useful options (unlimited calls to foreign mobile numbers, mobile hotspot with no extra charge).
Also think about your device's everyday security: a generous data plan is pointless if the phone running it is poorly protected, as this feature on protecting a smartphone from attack attempts points out.
Pitfalls to Avoid
The first pitfall: an automatic price increase after 12 or 24 months. Many plans, including no-contract ones, include a scheduled rate increase from the moment you sign up — read the fine print before committing. The second pitfall: in-store offers that are pricier than those available online, often bundled with unwanted options slipped into the contract. A third, rarer but real pitfall: some carriers still charge termination fees, even though the whole point of a no-contract plan is being able to leave freely.
A poorly chosen plan can also push you to switch phones frequently or get a damaged device repaired: this overview of what can actually be repaired on a smartphone helps you sort things out before buying a new phone.
Using Your Plan Wisely Day to Day
Once you've chosen a plan, a few simple habits help you avoid data overages and unpleasant surprises at the end of the month: track your usage through your online account, turn off automatic updates over 4G/5G, or set up usage-threshold alerts. Android users will find step-by-step explanations in these tutorials devoted to Android smartphones, which are useful for taking back control of your phone's settings.
How to Switch Carriers Without Losing Your Number
Number portability is a right: just request your RIO (relevé d'identité opérateur, or “operator ID statement”) via a free text to 3179, then pass it on to your new carrier when you sign up. The new carrier then takes care of canceling your old line: no further action is needed with your previous provider.
Frequently Asked Questions
Does a no-contract plan cost more than a plan with a contract?
Not necessarily: among MVNOs and the low-cost brands of established carriers, no-contract plans are often just as competitive as — or even cheaper than — equivalent plans with a contract.
Can I keep my number when switching to a no-contract plan?
Yes, thanks to number portability: just request your RIO code via a free text to 3179 before signing up with the new carrier.
Are there fees if I cancel a no-contract plan?
In principle, no — that's the whole point of this type of plan. But some carriers still include limited termination fees, so it's best to check the terms and conditions before signing up.
