AT&T Plan No-Brainer for Full and Part-time Expats in Mexico


Updated 2018

One of the thornier issues of living in two countries and staying in Mexico for extended periods is what to do about a phone plan.  As you hopefully are cycling out of your contracts, now is the time to think about what you want in a plan.

Make sure your next phone is unlocked

As you know, "free" phone offers with contracts are nothing more than a long term (2-3 year) installment payment plan for the latest phone.  The phrase "locked phone," couldn't be more descriptive in that the carrier "locks" you to the specific plan by giving you a phone that's only operational with that plan.

Having a locked phone limits your options when you're preparing to move to Mexico full or part-time.  If you live in Mexico, you will quickly see that no expat pays what Americans do for phone service. The great news is that you now have the right to get a phone unlocked for free when your contract expires. It's the law.

Next time you buy a new phone, make sure you buy an unlocked one. If you travel, opt for an unlocked dual Sim card phone to give the broadest possible choices for phone plans.

Waiting out the contract

If you are still tied to a plan, stop by your carrier's office and find out about its Mexico plans before you leave. They all have them and are moving towards free calling to and from Mexico, the U.S and Canada.  

You are already paying for the data and it may not cost you any or much more to switch the type of plan that would ensure uninterrupted calling and data while in Mexico.

When you return from Mexico, you have to go in and switch the plan back. While not always the most economical, if you have a plan and are staying only a month or two in Mexico, it's about all you can do.  

If you are anticipating becoming an expat, you'll definitely want to start moving toward something cheaper, without a U.S. contract.


Make sure you understand how roaming charges work.

I'd heard so many stories about coming home to  $500 phone bills due to roaming charges people didn't know they were incurring that I kept my phone in airplane mode during my whole first tour. 

Ya sabes (you already know) how I feel about telephone contracts and the major carriers. I have described in rather graphic detail my aversion to their small print, hidden charges, marketing practices and their documented data racketeering.  

A new AT&T program is helping me hate at least one carrier a little less. The AT&T plan available in Mexico is  a no-brainer if you live here over two months at time.  

Mexico's AT&T  No-Brainer Plan

For 200 pesos (about $10) a month, you get unlimited calling to the U.S., Mexico and Canada. You get one gigabyte of data.  No contract.

You have to buy two months (400 pesos/$20) the first time, after that it's month to month for 200 pesos - perfect for the jet setting expat.   

Here's what you need to do in Mexico. You go into an AT&T and ask for the plan. They take the SIM card out of your smart phone  and replace with theirs, giving you back your SIM card in a little envelope for safe keeping.

Should somehow you lose the chip, it's not a catastrophe. To replace the card you go to a AT&T (the main office which any larger Mexican city has) and buy a new one for 800 pesos ($40). They will not have them in the small customer service stores.

You receive a new number with the AT&T SIM Card, or you can transport your old number. 

The number isn't very important because the plan gives you unlimited calling TO the people in the U.S., Canada and Mexico. People can't call you FROM the U.S or Canada on that number unless they too have an international plan. 

For that, however, you can use an internet line, like Magic Jack.  I ported the U.S. number I've had for years to Magic Jack.

My U.S. friends continue to call me on the same number as they always have (You do have to remind them of that of first. When they see calls coming in from Mexico, they will try to call you on that number.)

When calling the U.S on the AT&T plan while in Mexico,  you do have to use the international code, 001, before dialing the  number.

Once you return to the U.S. you will have to change the Mexican numbers in your directory to include 52, the Mexican international code if you don't don't want to type them in. You can't call directly from your directory unless you change the directory number to include the international code. 

Picking a phone number for your AT&T account in Mexico

If you live in Mexico full time and have a smart phone, you can transfer your current Mexico number on the AT&T plan, like my permanent resident expat friends did. 

Pre-pay the AT&T number in Mexico for all the months you plan to be in the U.S.

The best part of the AT&T plan in Mexico is that before you go back to the U.S.,  you can pre-pay the $10 a month for each month you anticipate being in the U.S.  You will still have free calling to the U.S., Canada and Mexico and the data. That means you can call your U.S. friends when you're home on the plan.

Ten dollars a month for unlimited local calling and calls to Mexico, plus the data, beats anything you've seen available in the U.S. by quite a margin.

If you stay longer than planned in the U.S. and the plan runs out, a second choice would be Team Mobile's $53 a month, no-contract plan.  Then you'd have to replace the chip with the original chip and purchase the calling/data month to month.

To summarize the system, for $10 a month through the AT&T plan you have one gig of data and can call your friends in the U.S and Mexico using a major carrier.   You can receive calls and texts from the U.S. over the internet via  Magic Jack or WhatsApp. 

Similar plans

AT&T, Telcel, Movistar and Virgin Mobile currently offer a month-to-month plans (no contract) for MXN$200 pesos (US$11) that includes unlimited call minutes and SMS messages across North America (Mexico, the US and Canada), and at least 500 MB of data.  

An additional 1 GB of data is included for use of Facebook, Twitter, and WhatsApp. Visit the websites of the mobile operators to learn about these new unlimited plans which offer good value for money.

You've got to think outside the box when you live the part-time expat life. 

The main thing you want for your expat lifestyle is free international calling, some data, internet calling options and no contracts.   Using a combination of Magic Jack or another internet phone service (or WhatsApp)  and AT&T's $10/month plan could be your solution.

This  system keeps my phone bill as I jump between countries down to less than $15 month for international calling,  a gig of data and no contract.  If I average out the cost of the phone I bought online ($250), the $10 a month for the AT&T plan,  a few dollars a month for the Magic Jack service, and a few dollars keeping a cheap Telcel phone number active,  the monthly total is less than $25 a month (based on using the same smart phone for three years).

The story of my weird Telcel phone

When I first moved to Mexico, I bought a $35 Telcel phone in which to keep Mexican contact names, cab driver phone numbers and all things Mexican. 

 I regularly put sueldo on it, paying 100 pesos every few months at the OXXO to keep the number, or ask my business associate, the Intrepid Elise, to put a few pesos on it once in awhile for me while I'm gone (That she says not-a-word about doing this signals to me a certain level of endorsement). 

I've had the thing for four years now. It's still the number my Mexican friends call me on when I'm in Mexico. When that phone rings, I know it's a Mexican on the other end. It's my Mexican Bat phone.

I could have transferred that Telcel phone number to my smart phone with the new AT&T account, giving me one Mexican number.

I took a new AT&T number for several reasons.

For one thing, I wouldn't be able to use the number on both the Telcel phone and my smart phone.  I'd have to choose. The number can't be parked on two phones.

For another thing, I've grown rather fond of the Telcel phone. It's like a little landline that fits in the front of my jeans.  It's also indestructible. I can't count the number of times I've dropped it, picked up the pieces from the ceramic floor and fired it up again like nothing happened.

This kind of little emergency phone is handy to have. No one's going to steal it. It fits into the smallest of pockets.  I've even had the occasion when my smart phone ran out of battery, necessitating calling a regular cab on the Telcel phone when I couldn't access Uber. 

One of the hardest transitions to make in assuming the part-time expat lifestyle was creating a phone system that was cheap and still gave me what I needed. Consider what you really need vs. what you're used to, and you will likely save a boatload of money.
