You write to a cousin in Morocco, a friend in Tunisia, a colleague in Senegal, a contact you met while travelling in Mexico. The number is right, the international format is correct, the text goes out, your plan is charged. And nothing happens — for weeks. In the vast majority of countries outside the European Union, your recipient's line is a prepaid SIM. A prepaid line with no credit generally keeps receiving texts, but can no longer send any: your message arrived, the reply can't leave. And if the line has passed its validity period, it is suspended and then recycled — your text then goes to a number that no longer exists, or that already belongs to someone else. In every case, your carrier bills you for sending it.
Updated 4 November 2026.
Can a prepaid line with no credit still receive a text?
Yes, almost always. Receiving a text costs the recipient nothing in virtually every country: the sender pays. A prepaid line at zero therefore stays "attached" to the network and receives messages, often for months.
That's the fundamental difference, and it's what creates the misunderstanding. On a prepaid line:
- receiving a text: free, works as long as the line is active;
- sending a text: deducted from the credit, impossible at zero;
- receiving a call: generally free, so possible;
- making a call: impossible at zero, except for emergency numbers and the carrier's customer service.
In other words, when your contact "isn't answering", the most likely explanation isn't that nothing arrived: it's that they read your message and can't afford to reply. Many prepaid users top up in small amounts and have to choose between data, local calls and international texts — which, on their side too, are the most expensive item on the price list.
Before concluding there's a technical problem, turn the question around: does my recipient, right now, have the means to pay for a reply to a French number?
How long does a prepaid line stay reachable without a top-up?
That depends on a concept most French users have forgotten, because monthly plans made it disappear: the validity period. Each top-up opens a window during which the line stays active — often 30, 90, 180 or 365 days depending on the amount.
Once that window closes, the scenario unfolds in three stages, with durations that vary by carrier and local regulation:
- Outgoing validity expired. Any remaining credit is frozen or lost, and the line can no longer send. It often keeps receiving calls and texts during a grace period.
- Suspension. The line receives nothing at all. Your texts are then either rejected or stored for a few days in your carrier's message centre (the SMSC) before being dropped — the same mechanism as for a phone that has been switched off for a long time.
- Termination and recycling. The number goes back into the carrier's pool and can be reassigned to a new customer. Your messages then land with a stranger.
| Stage | Does the line receive your texts? | Can it reply? | What you see |
|---|---|---|---|
| Credit at zero, validity still running | Yes | No | "Sent", no reply |
| Validity expired, grace period | Often yes | No | "Sent", no reply |
| Line suspended | No | No | "Sent" then nothing, or failure |
| Number recycled | Yes, but by a third party | Yes, but it isn't your contact | Odd reply, or silence |
Exact durations are not standardised: they are set by each carrier and by the national regulator. The only reliable source is the "validity conditions" or "credit expiry" page of the recipient's carrier, not a forum.
How do I tell whether it's the credit, the line, or my own sending?
By testing in a specific order, from the cheapest to the most expensive. The goal is to isolate the cause before you keep paying for messages that lead nowhere.
- Check the number format. Country code, local leading zero removed, no stray spaces or dashes: a wrongly saved number will never go out, and that's the most mundane cause of all. The format details are in our guide to the international format of a foreign number.
- Call once, briefly. A carrier message in the local language ("this number is no longer assigned", "the subscriber is temporarily unreachable") is worth a thousand guesses. A normal ringtone means the line is active: your text is getting through.
- Try a data channel. If your contact still shows up on WhatsApp, Signal or Telegram with a recent "last seen" date, the SIM is alive and they have coverage — see what happens when your contact only has WhatsApp.
- Change the sending network. Send the same text from another line, on a different French carrier. If sending fails on both sides, the problem is at the recipient's end.
- Don't rely on delivery reports. Internationally they are very unreliable: some networks return a report as soon as they accept the message, others never return one at all. We explain why in the article on international delivery reports.
For contacts you reach only rarely, keeping a written record saves you from repeating the whole investigation every time: a small handwritten address book, with the full country code and the carrier, lasts better than a synced contact card that duplicates itself from one phone to the next.
Why hasn't my "sent" message arrived?
Because "sent" means one thing only: your phone handed the message over to your carrier's network. Nothing more.
An international text's journey involves at least three relays: your carrier, one or more international carriers (the SMS hubs), then the receiving carrier. Each relay can accept the message and then destroy it without telling anyone. This happens particularly often when:
- the receiving carrier filters messages coming from certain interconnection routes, as an anti-fraud measure;
- the number has been ported to another local carrier, and the country's portability database is poorly replicated on the international side — a case covered in detail in our article on texts to a ported number;
- the message contains accented characters or emoji, which switch it to Unicode encoding: the usable length drops from 160 to 70 characters and the message is split into several parts. Some international gateways reassemble those parts badly, and the recipient gets a truncated text, or nothing at all.
On that last point, the rule is simple and it makes a real difference: when sending to a prepaid line in a country with fragile interconnection, write short, without accents and without emoji. You mechanically increase the odds of delivery.
What should I do if the number has been recycled?
Stop writing, and check before sending anything else. A recycled number is the worst case: your messages do arrive, but with someone else.
The warning signs:
- a reply that doesn't match the context, or that comes in another language;
- a WhatsApp profile picture that has changed to an unfamiliar face, even though the number hasn't changed;
- a number that rings normally while your contact insists they no longer use it.
In that situation, send nothing personal any more: identity details, address, photos, bank references, codes you've received. A recycled number is an open channel to a stranger. The instinct is the same as for any suspicious incoming message, and it ties in with the data-protection good practices we set out in protecting your privacy when sending a text from the internet.
How do you stay reachable when you're the one travelling with a prepaid SIM?
By understanding that the problem works both ways. If you buy a local prepaid SIM while travelling — in Morocco, Turkey, Thailand, the United States — your new number is subject to the same validity rules, and your family and friends back in France will run into the same silences.
A few practical precautions:
- note the date and amount of every top-up, along with the validity period it opens. That's the piece of information nobody remembers, and it explains lines that go dead three months after you get home;
- keep the balance-check code (often a code in the form
*xxx#) and the one that shows the line's own number: on a prepaid phone, the screen doesn't display your own number; - keep your French SIM active alongside it if your device allows: a dual-SIM phone, or a local eSIM sitting next to your French line, stops you losing the texts sent to your usual number — bank verification codes in particular. We covered this trap in detail in the article on the local SIM that makes you lose your French texts;
- store your French SIM card properly if you take it out: a SIM card storage case costs a few euros and saves you from a SIM lost at the bottom of a bag, cut up or gone for good;
- bring a way to recharge, quite simply: a compact power bank mainly serves to keep a phone capable of receiving a text during long journeys where no socket is available.
And on the French bill, what are you actually paying for?
The sending, every single time, even with no delivery. That's the basic rule of texting: there is no refund for an undelivered message, and no French carrier commits to one.
From France to a country outside the European Union, texts are in principle outside your plan allowance, billed per message, with the rate depending on the destination zone. The "international rates" tables from Orange, SFR, Bouygues Telecom and Free Mobile are published on their websites and change regularly: the right instinct is to reread them before a batch of messages, not after. For destinations within the European Union, the roaming regulation caps rates when you are abroad, but not messages sent from France to a foreign number: these are two distinct situations, and they are often confused. The Arcep (French electronic communications regulator) documents this framework and publishes usage figures for texting in France, including the continuing decline of texts sent while roaming.
Three practical consequences:
- test with a single message, not with five;
- don't follow up in bursts: every follow-up is billed and none of them changes the outcome if the line is suspended;
- switch to a data channel as soon as you can. RCS won't solve anything here — it assumes both ends are compatible and connected, as we explain in RCS versus SMS: why texting is losing ground in France. For a prepaid contact abroad, a messaging app remains the most reliable and the cheapest route.
For a one-off message to a foreign number, you can also go through our online text messaging service rather than your mobile plan, and check the destinations covered and the cost on the pricing page.
Key takeaways
- A prepaid line with no credit receives your texts but cannot reply: silence doesn't mean non-delivery.
- A prepaid line lives by its validity period, not by its balance: once that expires, it is suspended and then the number is recycled.
- The "sent" label only confirms handover to the French network, never reception.
- Writing short, with no accents or emoji genuinely improves delivery on fragile international routes.
- A recycled number is a channel to a stranger: nothing personal from then on.
Frequently asked questions
Does a text cost the prepaid recipient anything?
No, in virtually every country receiving a text is free. The sender pays. That's why a line at zero can read your messages without being able to reply.
How long does a foreign prepaid number stay active without a top-up?
There's no single rule: the duration depends on the carrier and the country's regulator, and ranges from a few weeks to a year depending on the amount of the last top-up. Only the official page of the carrier concerned gives the right answer.
My text says "sent", so why isn't it arriving?
Because "sent" only means your carrier accepted the message. Between that carrier and the recipient's phone, several international carriers can drop it without any notification.
Can I get a refund for an undelivered international text?
In practice, no. Carriers bill for sending and don't guarantee delivery of a text, which is treated as a "best effort" service. Hence the value of testing with a single message.
How can I tell whether the number has been reassigned to someone else?
A short call, a messaging profile picture that has changed without the number changing, or an out-of-context reply are the most reliable clues. When in doubt, stop sending personal information.
