Calling your friends or relatives in the United States may seem like a confusing process at first. However, there are several ways to stay in touch with people in the U.S., including using international roaming on your cell phone, a prepaid calling card, a Mexican SIM card for your cell phone and VoIP services.
Switch to FaceTime to call or video chat with other Apple device users. FaceTime is the video and audio chat feature on Apple devices (Macs, iPhones, iPads) that uses data instead of minutes. This means you can easily make international video and audio calls without worrying about extra charges.
Buy a calling card with a low billing increment. Calling cards provide toll-free or local rate numbers to access international calling services. They are usually available at convenience stores or grocery stores. Look for a card with a low billing increment, which means you’ll be charged as close to the length of the call as possible.
Opt for a monthly plan with no contract. Many of Mexico’s major cell phone providers offer monthly no-contract plans for as little as 200 pesos (US$11). You can sign up for one of these plans at local cell phone provider stores.
Dial 00 and then 1, which is the U.S. country code. 00 is the Mexican exit code and 1 is the country code for the United States. Each exit code and country code is different, but you can easily look them up here: https://www.howtocallabroad.com/codes.html
Dial the 3-digit area code and the 7-digit number you want to call. Each service territory in the United States is assigned a three-digit area code that precedes all phone numbers originating from that location. Dial this number, then follow it with the 7-digit phone number you are trying to reach.
Buy an unlocked cell phone. Unlocked cell phones are phones that are not tied to a particular carrier. They are usually more expensive than regular phones because they are compatible with any cellular service provider. The advantage, however, is that you can connect them to providers in countries other than your home country.
Reload your SIM card if you don’t have airtime or data. If your SIM card purchase did not include airtime or data, visit a local convenience store or phone store to add data to your plan. The transaction is done electronically – you provide them with your phone number, then you should receive a receipt and SMS text message from the carrier confirming the purchase.
Use Skype to call landlines and other Skype accounts. Skype is one of many Voice over Internet Protocol services, which uses wifi or cellular data to call instead of minutes. If the person you’re trying to reach is also a Skype user, you can call them for free, regardless of distance. Download the Skype app from the iOS App Store or Microsoft Store. Then create an account using your email address.
Enter the PIN shown on the card. Each calling card will have an individual PIN. Dial this number when prompted by the automated voice. It may indicate how many minutes you have left on the card so you know how long you can talk.
Call your cell phone provider to enable international roaming. If you are visiting Mexico and want to be able to reach your loved ones at home, call your health care provider before your trip and tell them the dates you will be in Mexico. Then they can activate international roaming, which will give you access to voice, text and data using that country’s local cellular networks, but usually at higher rates.
Dial 00, 1, the 3-digit area code and the 7-digit number. From there, to make a call, dial the Mexican exit code (00), the country code for the U.S. (1), the area code of the number you are trying to call and the number itself. Talk as long as the airtime you purchased allows!
Use WhatsApp for free international voice and video calls. Like Skype, WhatsApp uses the Internet to connect you to the person you are trying to call. The only requirement is that the person you are trying to reach is also a WhatsApp user.
Buy a SIM card for a Mexican mobile operator. A SIM (subscriber identification module) card is a tiny card that slides into your phone (often near the battery) and gives the phone its phone number and access to service. Go to a cell phone store in Mexico and buy a SIM card for one of the major Mexican cell phone operators – Telcel, Virgin Mobile, Movistar, or AT
