Call Mexico from the US for as low as $0.01/min. Step-by-step dialling guide with +52 country code, city codes, and cheapest calling options.

Mexico is the #1 most-called country from the US. With over 36 million Mexican Americans and the US-Mexico border being the most-crossed international boundary in the world, the demand for cheap US-to-Mexico calling is massive.

Good news: calling Mexico is one of the cheapest international routes. But you still need to dial correctly and avoid carrier markups that charge 10-50x more than necessary.

How to Dial Mexico From the US

+52 + 10-Digit Number\n\nExample (mobile): +52 55 1234 5678\nExample (Guadalajara): +52 33 1234 5678\nExample (Monterrey): +52 81 1234 5678

Step by Step

Dial + (or 011 from a landline)

Dial 52 (Mexico country code)

Dial the 10-digit number (area code + local number)

Since 2019: Mexico eliminated the need to dial "1" before mobile numbers. All Mexican numbers (landline and mobile) are now 10 digits. Just dial +52 followed by the 10 digits.

Mexico City Codes

Major cities (Mexico City, Guadalajara, Monterrey) have 2-digit area codes. Smaller cities have 3-digit area codes. The total is always 10 digits.

Cheapest Ways to Call Mexico From the US

T-Mobile includes free calling to Mexico (landlines and mobiles) on most current plans. If you have T-Mobile, check your plan details before paying for a third-party service.

Special Case: T-Mobile Mexico Calling

T-Mobile includes Mexico calling in several plans:

Magenta and Magenta MAX: Unlimited calls to Mexico and Canada included

Essentials: Unlimited calls to Mexico included

Go5G and Go5G Plus: Unlimited calls to Mexico included

If you are on one of these plans, you can call Mexico at no extra charge. Just dial +52 followed by the number. However, call quality over the carrier network can be inconsistent for long calls. BubblyPhone over WiFi often sounds better.

Best Option by Situation

You have T-Mobile

Use your included Mexico calling. Switch to BubblyPhone only if call quality is poor.

You have AT&T or Verizon

BubblyPhone at $0.01-0.03/min. A 30-minute daily call to Mexico costs about $27/month on BubblyPhone vs $900/month on Verizon.

Calling Mexican businesses

BubblyPhone — works from your browser, no app to install. Ideal for calling hotels, restaurants, or offices in Mexico from your computer.

Calling family with smartphones

WhatsApp — extremely popular in Mexico. Nearly everyone has it. Free for voice and video calls. Use BubblyPhone when they cannot pick up WhatsApp.

Common Mistakes

1. Adding "1" before the number

This was required before 2019 for mobile numbers. It is no longer needed. Just dial +52 + 10 digits.

2. Dialling 044 or 045

These prefixes were used for domestic calls to mobiles within Mexico. Never include them when calling from the US.

3. Not checking your carrier plan

T-Mobile includes Mexico calling for free. AT&T has a $10/month Mexico add-on. Check before paying third-party rates.

Best Times to Call Mexico

Mexico spans 4 time zones, but most of the population lives in Central Time (CT), which is the same as US Central Time.

Business hours in Mexico are generally 9 AM to 6 PM. Lunch breaks (2-4 PM) are sacred — businesses may be less responsive.

Summary

Mexico is the cheapest major country to call from the US, with rates as low as $0.01/min on landlines. Check if your T-Mobile plan includes it for free. Otherwise, BubblyPhone at $0.01-0.03/min makes every other option look expensive. Always dial +52 + 10 digits — no extra prefixes needed.
