You've booked an apartment in Lisbon, a hotel in Marrakesh, a car in Athens. The email address bounces back nothing, so you send a text to the number on the confirmation. The message goes out, it's billed at the international rate, and it never gets an answer. Most business numbers abroad — hotel switchboards, front-desk lines, customer service numbers, professional landlines — are technically incapable of receiving a text message, or they land in an inbox nobody ever checks. The message isn't lost in the network: it arrives at a piece of equipment that has no way to display it. Your carrier bills you for sending it either way, with no refund.
Updated 3 November 2026.
Why doesn't a hotel receive my text message?
Because the number printed on a booking confirmation is, nine times out of ten, a landline or a switchboard number — not a mobile line.
A text message isn't carried the way a call is. It travels through the mobile network's signalling layer and must be delivered to equipment capable of storing and displaying it: a SIM card in a phone, or a business gateway explicitly configured for the purpose. A hotel PBX, a DECT handset sitting on a counter, a reception number running over voice-over-IP have none of those capabilities.
Three things can happen, and none of them is flagged to you:
- the message is rejected immediately: you see a send failure, sometimes an error code. That's the least painful outcome, because at least you know;
- the message is accepted by the network and then silently discarded: your phone displays "sent", your plan's counter ticks up, and nothing else ever happens. This is the most common case with landlines and switchboards;
- the message really does land in a web interface or a text voicemail box that nobody ever checks, because the business doesn't even know the channel exists.
We break down the general mechanics of non-mobile numbers in our article on sending a text message to a landline, and the particular case of numbers hosted on servers in the one devoted to virtual and VoIP numbers.
How can I spot a number that will never read my text?
There's no universal rule, but a few highly reliable clues let you make the call before sending — and therefore before paying.
| Clue in the number | Chance of receiving a text | What to do |
|---|---|---|
Foreign city area code (e.g. +351 21 Lisbon, +30 210 Athens, +34 91 Madrid) | Very low | Call, or write by email |
Number starting with +800, or a national freephone number | None | Call — often free from inside the country only |
| National short code (3 to 6 digits) | None from abroad | Use the app or the website |
| Mobile number for the country (national mobile prefix) | Good | Text is possible, reply uncertain |
| Number advertised as "WhatsApp" on the business's website | Varies | Use WhatsApp, not SMS |
| Booking platform number | None | Use the platform's internal messaging |
Short codes are a classic travel trap: a service number that works perfectly from a local SIM card becomes unreachable from a French line, as we explain in the article on texting short codes from abroad.
Numbers advertised as WhatsApp are the other great source of misunderstandings. A business that gives out a "WhatsApp" number doesn't necessarily have a phone able to receive a standard text on that same line: it may be a WhatsApp Business account tied to a landline, verified once by voice call. We cover the topic in detail in our article on numbers that only have WhatsApp.
Is the number format to blame?
Often, yes — and it's the only part of the problem you control entirely.
A business number is frequently displayed in a local format, with spaces, dots, brackets, a leading zero or an extension. None of that works from France. Three rules to apply:
- Replace the local international prefix with
+.00,011,0011all become+. - Drop the leading zero of the national number after the country code, in every country that uses one (Portugal excepted — it has no trunk zero).
- Remove any extension such as "ext. 204", "ext. 12": an extension is dialled after the voice call connects, and means nothing in a text message.
A concrete example with a Spanish hotel listing (+34) 91 123 45 67: you dial +34911234567, with no spaces. With an Italian restaurant listing 02 1234567, you dial +39021234567 — Italy keeps its zero, unlike France or the United Kingdom. These exceptions are documented number plan by number plan in the ITU international numbering plan, the official reference on the subject.
Our article on incorrectly saved foreign numbers explains how to fix an address book for good, which saves you rebuilding the format on every trip. For a long stay, jotting down the numbers you need in a pocket travel notebook remains the simplest precaution: a dead or stolen phone leaves you with no access to a single contact.
What should I use instead of a text message?
There's almost always a more reliable channel, and often a free one. In order of how well they actually work:
- The booking platform's internal messaging. This is the channel businesses do check, because their reviews and ranking depend on it. Replies come faster than by phone.
- WhatsApp, Telegram or Signal when the business explicitly advertises it. These messages travel over data, so they're free on Wi-Fi, and they leave a written record both sides can consult.
- Email, for anything that needs a paper trail: late arrival time, cancellation request, complaint. A time-stamped email beats a text you'll never know was read.
- A voice call, as a last resort, preferably from a voice-over-IP app on Wi-Fi rather than roaming outside the European Union.
- RCS, which is gradually replacing SMS in France. It won't help with a hotel switchboard, but it explains why some of your business messages in France now land in a verified conversation: see our article on RCS Business Messages.
For any of these channels to work, you need network or Wi-Fi, and battery. Which is why a travel power bank and a universal plug adapter are in the luggage of everyone who has ever spent a night-time arrival hunting for an address with an unusable phone.
How much does a text sent into the void cost?
The price of a standard international text message, billed the moment the network accepts it, whether it's delivered or not.
On French consumer plans, sending a text to a number outside the European Union from France is generally billed on top of your plan, at around €0.13 to €0.30 depending on the carrier and the destination zone. Texts to a number in an EU country or the European Economic Area (Iceland, Liechtenstein, Norway), on the other hand, are capped by the European regulation on intra-EU communications at €0.06 excluding tax — and many carriers simply include them in the plan.
One important point: the European cap applies to intra-EU communications, meaning from France to another Union country, and not to messages sent to Morocco, Turkey, Switzerland or the United Kingdom, which remain outside that framework. For travel beyond Europe, our guide to texts and data outside the European Union sets out the rate cards and the billing traps.
Three or four attempts to reach a switchboard that receives nothing therefore represent a real cost, for zero result. Always check your carrier's official rate card — "out of plan" prices change several times a year.
No French carrier refunds an international text that was "sent but not delivered". Billing is triggered when the message centre accepts the message, not when it's delivered to the recipient.
What if the business texts me first?
That's the reverse setup, and it works perfectly well — but the reply almost always fails.
A hotel, an airline, a rental company or a foreign bank sends its notifications through a professional channel: an SMS gateway tied to an alphanumeric sender ID (the brand name instead of a number) or to a technical number. These senders are one-way by design: they can send, not receive. Replying "YES", "CONFIRM" or "thanks" to a message signed BOOKING or IBERIA gets you nowhere.
One clue is enough to recognise them: if the displayed sender is a name rather than a number, or a very long and unusual number, no reply is possible. The message often says "do not reply to this message" in its original language anyway.
Messages arriving from an apparently ordinary number call for even more caution: our article on texts received from abroad and the cost of replying explains how a simple reply can be billed far above the advertised rate.
The special case of late arrivals and emergencies
When you absolutely must reach a business within the hour, a text message is the worst possible choice — including to a genuine mobile number, since nothing guarantees it will be read.
The sequence that works, in order:
- A message in the booking platform, time-stamped and visible to the business on its dashboard.
- A voice call, ideally through an app on Wi-Fi if you're outside Europe.
- WhatsApp, if and only if the business advertises the number as such.
- Email, which isn't there to be read within the hour but to prove you gave notice.
And one habit to adopt before you leave: screenshot the critical information — full address, entry code, booking reference, directions — so it stays readable with no connection. A waterproof phone pouch and a multi-socket travel charger are worth more than a theoretical plan B when it's pouring with rain as you get off a train at 11 p.m. If you're travelling with no guarantee of network, our guide to texting over Wi-Fi abroad sets out what actually works without mobile coverage.
Frequently asked questions
Can a hotel receive a text on its landline number?
Technically it's possible if the business has signed up for a "SMS to landline" service with its carrier, but it's rare and almost never advertised. Unless the hotel's website explicitly says so, assume it can't.
Why does my phone say "sent" if the message never arrives?
Because "sent" only means your carrier's message centre has accepted the message. The delivery receipt depends on the destination network and is frequently wrong internationally: that's the subject of our article on SMS delivery receipts.
Can I get a refund for texts sent to a number that can't receive them?
Not in practice. Billing is triggered when the message is accepted, regardless of delivery. Only an obvious pricing error — a price different from the carrier's published rate card — can justify a complaint.
Should I include the country code even when calling from inside the country?
Yes, it's actually preferable. A number saved in international + format works from any network, in France as well as on site, and saves you reformatting your contacts at every border.
Do foreign freephone numbers receive text messages?
Never. A freephone or special-rate number (+800, national 0800 numbers and their equivalents) is voice-only, and it's generally unreachable from abroad, even for calls.
Key takeaway: before texting a business abroad, look first at what kind of number it is. City area code, freephone number, short code, alphanumeric sender: in those four cases the text is lost before it leaves, and billed all the same. For a reliable written exchange, the booking platform's messaging or email remain the only channels where you'll see a reply. And for your messages to genuine mobile numbers, you can send a text through our service or check the pricing before you go.
