How to Text a Mexican Number? A Complete Guide

Texting someone in Mexico can be tricky if you’re not familiar with the local dialing rules or international codes. Even a small mistake, like missing a prefix or using the wrong format, can prevent your message from reaching the right person.
The good news is that texting Mexico from any country is simple once you understand the international phone number format for texting.
In this guide, we’ll explain how to text a Mexican number domestically and internationally. Moreover, we’ll cover the best alternative texting methods, legal considerations, and best practices to help you text Mexican phone numbers without any issues.
Things You Need to Know Before Texting Mexico
Before texting Mexico, you must understand the Mexico phone number format, consider carrier charges, and be aware of any international restrictions. It’s also crucial to follow the legal requirements and keep your text under 160 characters to avoid messages being split into two.

- Mexico Phone Number Format: Ensure you use the correct Mexico phone number format when texting to ensure your text reaches accurately. When texting internationally, always add +52, Mexico’s country code, before the 10-digit mobile number.
- Carrier Charges: Verify the cost with your carrier provider before sending texts. International texting often comes with extra fees, and frequent texting without a plan can become expensive.
- International Restrictions: Consider whether your carrier allows SMS to Mexico. Some networks may block international messaging. So, always confirm compatibility before sending text messages.
- Legal Considerations: Ensure compliance with Mexican communication laws when sending texts for business. Always obtain consent before sending promotional or bulk messages to avoid penalties.

Alternative Method to Text a Phone Number in Mexico
Traditional SMS methods can be expensive, and charges can quickly add up, especially for international texts. To save money, consider using a virtual phone number, messaging apps like WhatsApp/Viber, or Wi-Fi calling.
1. Virtual Phone Number
A virtual phone number allows you to send texts over the internet. A VoIP (Voice over Internet Protocol) service provider like Calilio offers these online numbers with a lower per-SMS cost for texting both locally and internationally.

2. Online Messaging App
Messaging apps like WhatsApp and Viber allow you to send free or low-cost texts. However, both you and the recipient must use the same app and have a strong internet connection.
Here’s how to text a Mexican number using a messaging app:
- Install the Messaging App (eg, WhatsApp, Viber) on your phone.
- Create an account or log in using your phone number.
- Add the Mexican number in the correct international format.
- Type your message into the text field.
- Tap the Send button to send your message.
3. Wi-Fi Calling

If your device supports Wi-Fi calling and your carrier enables it, you can use this feature to text Mexico numbers when failing to send a message through traditional SMS.
Here’s how to text Mexico using Wi-Fi calling:
- Ensure Wi-Fi calling is enabled on your phone (this can usually be activated in your phone’s settings).
- iPhone: Go to Settings > Phone > Wi-Fi Calling and toggle it on.
- Android: Go to Settings > Connections > Wi-Fi Calling and enable it.
- Open your messaging app.
- Enter the recipient’s Mexican number in the recipient’s field.
- Compose your message.
- Tap Send to deliver the message using your Wi-Fi network.
Key Legal Regulations to Consider While Texting Mexico
While texting a Mexican number, you must obtain explicit consent for marketing or promotional messages and always provide an opt-out option. Additionally, avoid texting numbers on the REPEP (Public Registry to Avoid Publicity) list. Also, make sure you do not include any restricted content in your message.

Consent
In Mexico, you must get explicit consent from the recipient before sending any promotional or marketing messages. This consent must be clear and verifiable. You can collect it using opt-in messages for confirmations. Without consent, sending marketing messages is illegal and can lead to hefty fines.
Opt-Outs
Every promotional message you send must include easy-to-follow opt-out instructions. These allow recipients to unsubscribe from future messages. Ensure that your opt-out process is quick and that you stop sending messages once someone opts out.
REPEP (Public Registry to Avoid Advertisements)
Mexico has established REPEP (Public Registry to Avoid Advertisements), a list that allows individuals to register their phone numbers to block unwanted marketing messages. You must check if the particular number is on the REPEP list before sending a message.
Content Restrictions
Certain content, such as gambling, firearms, or political messages, is restricted in Mexico. Ensure your messages don’t include any prohibited content. Misleading or false claims can also result in penalties.
Conclusion
Texting a Mexican number is straightforward once you know the correct formatting. To text locally, simply dial the area code and subscriber number. For international texts, add the +52 country code before the 10-digit Mexican phone number.
Beyond traditional SMS, you can also use other alternatives like online messaging apps, Wi-Fi calling, or a virtual phone number to text in Mexico. A virtual phone number, in particular, offers the best solution.
A virtual phone number from Calilio, for instance, comes with a low-cost messaging rate and added flexibility. You can send texts from your smartphone, tablet, or computer using a VoIP app, without needing a physical SIM card. You can even get a Mexican virtual phone number and text Mexico from any country at a local rate.
