How to Send International Text Messages
To send an international text message, you need the recipient’s country code, area/city code (if any), and local phone number, then dial the full number as you would for a call. This guide explains the exact format, costs, and common issues you may face when texting abroad.
Understanding International Phone Number Formats
Every country has a unique country code (e.g., +1 for the US/Canada, +44 for the UK, +81 for Japan). When sending an international SMS, you replace the leading zero of a local number (if present) with the country code. For example, a UK number written as 07911 123456 becomes +44 7911 123456 internationally.
You must also include the area or city code for landlines, but for mobile numbers, the full number after the country code is usually sufficient. Always omit the international dialing prefix (like 011 from the US or 00 from most European countries) when using the + symbol, as + works on all GSM networks and most carriers worldwide.
How International SMS Works
When you send a text to a foreign number, your carrier routes it through an international SMS gateway. The message is delivered to the recipient’s carrier, which then forwards it to their phone. This process usually takes a few seconds, but can be delayed if the recipient’s network is congested or if the message must traverse multiple intermediaries.
Most modern smartphones automatically convert your message to MMS (multimedia) if you include emojis, photos, or long text over 160 characters. MMS international rates are typically higher than SMS, and some carriers do not support international MMS at all. If reliability is critical, consider using an internet-based messaging app like WhatsApp or iMessage instead, which bypasses SMS entirely.
How to Find the Correct Country Code
You can look up country codes in your phone’s dialer, online directories, or your carrier’s website. A few common ones are:
- +1 – United States, Canada, and many Caribbean nations
- +44 – United Kingdom
- +61 – Australia
- +49 – Germany
- +91 – India
- +86 – China
If you’re unsure, ask the recipient for their number in international format (with the + and country code). Most people in other countries know their own international format, especially if they travel or receive calls from abroad.
Costs of International Texting
International SMS rates vary widely by carrier and plan. Many postpaid plans include a small bundle of international texts, while prepaid users are charged per message. Typical per-message costs range from $0.25 to $1.00, but can be higher for premium destinations. Check your carrier’s rate card or your online account for exact pricing.
To avoid surprises, you can purchase an international texting add-on or use a messaging app that works over Wi-Fi or mobile data. Some carriers also offer unlimited international texting to specific countries as part of premium plans. Always verify the destination country’s rate before sending a large number of messages.
Common Problems and Troubleshooting
If your international text fails to send, check the following:
- Number format: Ensure you used the + sign and country code, and dropped any leading zero.
- Carrier restrictions: Some prepaid plans block international SMS by default. Contact your carrier to enable it.
- Recipient’s phone: The recipient may have international SMS disabled on their end, or their phone may be out of coverage.
- Message length: If your message exceeds 160 characters, it becomes MMS. Confirm your plan supports international MMS.
- Roaming: If you are traveling, your home carrier’s international roaming rates apply, which may be higher than standard international SMS.
If you still have issues, try sending a short test message to a friend in the same country, or contact your carrier’s support with the exact error message you received.
International SMS vs. Internet Messaging
Internet-based messaging apps (WhatsApp, Telegram, Signal, Facebook Messenger) use data or Wi-Fi, not your SMS plan. They are usually free, support rich media, and work internationally as long as both parties have the app and an internet connection. However, they require the recipient to have the same app and an active data connection.
SMS remains more universal—it works on any phone, even basic feature phones, and does not require an app or internet. But it is limited to 160 characters per segment (longer messages are split and can incur multiple charges) and lacks encryption. Choose SMS when you need guaranteed delivery to any phone, and choose an internet app when cost and features matter more.
Safety and Privacy Considerations
International SMS is not encrypted, so avoid sending sensitive information like passwords, financial details, or personal identification numbers. Be aware that international texts may be intercepted by carriers or governments in some countries. For confidential conversations, use an end-to-end encrypted messaging app.
Also, be cautious of scams that ask you to text international numbers—these often incur premium charges. Never reply to unknown international numbers, and check your bill for unexpected international SMS fees.
Frequently Asked Questions
Do I need to add a plus sign when sending international texts?
Yes, the plus sign (+) is the universal international access code and works from any country. It tells your carrier to interpret the following digits as an international number. If you omit the +, you must use your country’s specific exit code (like 011 from the US or 00 from most of Europe), which only works when dialing from that country.
Will my international text be delivered immediately?
Usually within seconds, but delivery can be delayed if the recipient’s network is busy or if the message passes through multiple carriers. There is no guaranteed delivery time, and some messages may take up to a few hours in rare cases.
Can I send international texts for free?
Some plans include free international texting to certain countries, but most carriers charge a per-message fee. Using an internet-based app like WhatsApp is free if you have a data plan or Wi-Fi, but it requires the recipient to have the same app.
Why did my international text get split into multiple messages?
SMS has a 160-character limit per message. If you exceed that, your phone splits the text into multiple segments, each billed separately. To avoid this, keep messages under 160 characters or use MMS (which may have a higher cost).
What is the difference between international SMS and international MMS?
SMS is text-only and limited to 160 characters. MMS supports multimedia (photos, videos, audio) and longer text, but is more expensive and not supported by all carriers for international delivery. Check your plan to see if international MMS is available.
Can I send international texts from a computer?
Yes, many carriers offer web-based SMS portals or email-to-SMS gateways (e.g., sending an email to the recipient’s number@carrierdomain.com). However, these methods may have different rates and delivery times. Alternatively, use a messaging app that has a desktop version.
