Short answer: a free trial or a €1 trial period hands the service provider a contract, your bank card and your mobile number. The texts that follow mix three families: legitimate contractual messages (trial ending, payment), marketing from the provider and its "partners", and fake messages that imitate the first two. You sort them by sender, wording and link — never by the urgency they claim.
Updated 10 November 2026.
You tried a streaming service for a week, photo-editing software for three days, a recipe platform for €1, a fitness-tracking app "free for 14 days". You gave an email address, a card number and — almost always — a mobile number, because signing up required a verification code.
Ever since, your message thread looks like a billboard: "Your trial ends in 24 h", "Last chance: -70% if you confirm", "Payment failed, please update your payment method". Some are genuine notifications from the provider. Others have nothing to do with it. And the most alarming ones are rarely the most genuine.
Why does a free trial generate so many texts?
Because the trial is not a gift: it is the start of an automatically renewing contract, and text messaging is the cheapest channel for seeing it through.
A service offering seven free days only makes money if some of the testers forget to cancel or decide to stay. The whole set-up is therefore built around two moments:
- the day before the switch, when the provider reminds you that it is about to charge you (a contractual, sometimes legal, obligation) and, in the same breath, offers you a discount so you do not leave;
- the payment failure, where every follow-up has a direct value: an expired card or a spending limit reached means a subscriber lost.
On top of that sits a third layer, which is not contractual at all: marketing. If the sign-up form included a box saying "I would like to receive offers from the provider and its partners", your number can be used for commercial messages unrelated to the service you tried. It is exactly the same mechanism described in our article about advertising texts after a prize draw: one checkbox, a chain of partners, dozens of different senders.
Finally, there are the fraudsters. Trial periods are a windfall for them, for one simple reason: at any given moment, millions of people in France are legitimately expecting a message about a subscription. A fake "payment failed" text sent at random is bound to hit home for some of the recipients.
How can you spot a legitimate trial text?
A genuine end-of-trial message names the service, asks for no banking details in the text itself and creates no minute-by-minute urgency. It points you to your account area, not to a payment form.
Here is a grid you can apply in ten seconds:
| Clue | Legitimate message | Fraudulent message |
|---|---|---|
| Sender | Consistent sender name or French short code (3xxxx / 2xxxx) | Unknown 06/07 number, foreign number, approximate brand name |
| Content | Names the service and the trial end date | Talks about "your subscription" without ever naming it |
| Request | "Manage your subscription in your account area" | "Update your bank card within 24 h" |
| Link | The provider's official domain | Odd subdomain, URL shortener, unexpected extension |
| Tone | Informative | Threat of suspension, countdown, fine |
The most telling point remains the name of the service. A provider knows which product you tried: it writes it down. A fraudster sending a hundred thousand texts does not know: they stay vague. "Your subscription is about to expire" with no brand name is, on its own, a very strong signal.
Beware of one trap, however: the name shown instead of the number proves nothing. That field is simply a string of characters declared by the sender, as we explain in A text signed with a brand name: trustworthy or not?. A message can display "NETFLX", "SUBSCRIPTION" or a provider's exact name and still come from somewhere else entirely.
The one habit that replaces all the others
Never check a subscription from the text message. Open the app or type the service's address yourself, then look at the "Subscription" or "Billing" section. If nothing has changed there, the text was fake. This rule applies to subscription follow-ups just as it does to the alleged renewals described in our report on fake subscription renewal texts.
What does French law say about the end of a trial?
A trial that turns into a paid subscription must have been clearly announced before sign-up, and cancellation must be available online just as easily as subscribing was.
Two useful, verifiable points of law:
- Pre-contractual information. The code de la consommation (French Consumer Code) — articles L. 221-5 and following, available on Légifrance (the official French legal portal) — requires the trader to state, before a distance order is placed, the contract's duration, its cancellation terms and the fact that the subscription renews. A struck-through price, a "free" claim with no follow-up and terms buried in a footer amount to a breach.
- Cancellation in three clicks. Under article L. 215-1-1 of the code de la consommation (French Consumer Code), traders who allow online sign-up must provide an online cancellation function that is directly accessible. Put plainly: if you are sent off to a premium-rate phone call or a registered letter to get out of a trial you signed up for in two minutes on a website, you can report it.
For disputes, the SignalConso (Report to Consumer Affairs) platform run by the Direction générale de la concurrence, de la consommation et de la répression des fraudes (Directorate-General for Competition, Consumer Affairs and Fraud Control) — signal.conso.gouv.fr — is the official entry point. It passes your report on to the company and feeds into DGCCRF enforcement work.
On the marketing side, the rule is the prior-consent requirement restated by the CNIL (cnil.fr), France's data protection authority: a commercial text message requires explicit agreement, and every message must offer a simple way to opt out — in practice, the word STOP ("stop") followed by a code. We set out how this system works, and where it falls short, in Replying STOP to a text: does it really work?.
How do you shut off the flow of texts after a trial?
By dealing with the two sources separately: the contract itself, then the marketing lists. Stopping one does not stop the other.
- Take stock of your active trials. On iPhone: Settings → your name → Subscriptions. On Android: Google Play app → your avatar → Payments and subscriptions → Subscriptions. These screens only list subscriptions taken out through the stores; those paid by card directly on a website do not appear there.
- Fill in the gaps with your bank statement. Look for round, recurring amounts (€1, €1.99, €9.99) over the last three months. Trial charges often show up under a company label that bears no resemblance to the service's trading name. Jotting those labels down in a spiral notebook or in a password manager saves you doing the whole exercise again six months later.
- Cancel from your account area, not from a link received by text, and keep the written confirmation.
- Reply STOP to every advertising sender. A single STOP only counts for the sender concerned. If fifteen different short codes write to you, you will need fifteen replies — free of charge and not premium-rated.
- Withdraw your consent at the source. In your account, look for "Communication preferences" or "Privacy" and untick everything relating to partners. You can also exercise your right to object by emailing the provider's data protection officer.
- Register with Bloctel (France's telemarketing opt-out list) at bloctel.gouv.fr for cold calling. Note: Bloctel does not cover advertising text messages, only calls.
- Report fraudulent messages to 33700 by forwarding the text, then the sender's number in your reply message. The service is free and described on our dedicated page about reporting unwanted texts to 33700.
And if the payment has already gone through?
First contact the provider in writing, asking for a refund and citing the lack of pre-contractual information if the trial did not clearly mention renewal. If there is no answer, file a report on SignalConso. If the charge has nothing whatsoever to do with any service you signed up for, it is an unauthorised transaction: your bank must refund it under articles L. 133-18 and following of the code monétaire et financier (French Monetary and Financial Code), within the timeframes set by the European payment services directive.
Why do fraudsters love trial periods?
Because they create a state of expectation. When you know a charge is due, a text message about it sets off no alarm bells.
The most common scenario in 2026 plays out in three acts:
"Your subscription could not be renewed: check your payment details to avoid suspension." Then a link to a very polished payment page. Then, sometimes, a call from a fake customer service team asking for the code you received by text to "validate the correction".
That third act is the costliest: the six-digit code you read out is used to authorise a real payment, or to authenticate the addition of your card to a mobile wallet controlled by the fraudster. We described this pivot in "Do not share this code with anyone". The rule is absolute: no verification code is ever read out to anyone, including someone who knows your name, your bank and the exact amount of your subscription.
Another recurring angle is the fake refund. "Your trial was charged in error, click to receive your €39.99 refund". A legitimate refund never requires you to enter a card number: the money is credited back to the original payment method.
How do you try a service without opening the floodgates?
By compartmentalising: a dedicated email address, a payment method with a low limit, and a number that is not the one your family and friends use.
A few habits that cut the noise for good:
- A test email address. Create an address reserved for sign-ups. It becomes an indicator: an "official" message landing in your main inbox when you signed up with the other address is necessarily suspicious.
- A virtual or capped card. Most banks offer single-use card numbers. Failing that, a rechargeable prepaid card mechanically limits the amount exposed.
- A second number. An eSIM or a prepaid SIM dedicated to sign-ups keeps your main phone clean. The method is spelled out in A second number for everything that is not your family and friends.
- A calendar reminder. The moment you activate the trial, set an alert for 48 hours before it ends. It is the most effective measure on this whole list, and the most often overlooked.
- An archive binder for printed cancellation confirmations, if you prefer paper: in a dispute, a dated record beats a memory.

Questions people ask
Can a text message sign me up to a subscription?
No, not merely by arriving. Replying with a keyword to a premium-rate message ("YES", "PLAY", "GO"), on the other hand, can count as signing up to a subscription service. If in doubt, do not reply at all and check your carrier bill.
Why am I still getting texts after cancelling?
Because cancellation ends the contract, not your marketing consent. You also have to reply STOP to each sender and withdraw your agreement in your account preferences, or even ask the provider to erase your data.
Can 33700 get me a refund?
No. 33700 is a reporting system: it feeds into carrier investigations and can lead to fraudulent numbers being shut down. For a refund, go through the provider, your bank, then SignalConso.
How can I find out which website sold my number?
It is rarely possible to know for certain. One trick: vary the spelling of your name slightly from one sign-up to the next. If a text calls you "Mr Durand-trial3", you know where the leak came from. The principle is the same as the one described in our article on where delivery data leaks come from.
Should I block the numbers chasing me?
Blocking brings short-term relief but does not dry up the source: bulk-messaging platforms change number with every campaign. Our explanation of what blocking a number really stops covers the limits of that approach.
