"If there is one important bit of information to learn from reading this is that you need to be extremely sure of what plan you have before venturing off  (overseas) with your phone. Almost all the main carriers, Verizon, Sprint, AT&T, and T-Mobile, offer affordable and even free roaming in Mexico. However, they also all have older plans that offer costly roaming rates. If you don't ask for the cheaper plans, they certainly are not going to volunteer it. Here is another great tip. If by chance you incur huge roaming rates, call your carrier and ask them if they can activate a better plan retroactively and charge you accordingly. If they are not willing to do so, get a supervisor on the phone and remind them that there are other carriers in town." Cellular Abroad

 

KNOW BEFORE YOU GO

Before departing overseas, contact your provider's customer support and as about their 

• international roaming at your destination 

• SIM card availability

• rates, and policies 

For example, Our cell provider is Verizon and our next destination is Mexico. Through Verizon, Mexico and Canada are considered extensions of our existing plan. That means there will be no change in our usage or monthly billing. 

 

What Service To Expect At Your Destination 

Check for current information before each departure. 

• GB data slowdown. Customer Support informed us to expect a service-slowdown once 1/2 GB is used up. That means that although our Verizon plan includes 16 GB for the month, when in Mexico (international), once 1/2 GB of cellular data is used up, the service slows way down until midnight and then resets for the following day. As long as we use wifi, data is unlimited. 

• Checking Your Voicemail While overseas: Check voicemail simply by dialing +1 then your 10-digit mobile number. Not all carriers are alike, so confirm voicemail procedure for each destination before departing to your destination.

Find Out If your smartphone is unlocked.

You can avoid all roaming charges with an unlocked GSM (Global System for Mobile Communications) smartphone, a network standard for the world. Carriers "lock" their devices so if you put an AT&T SIM card into a T-Mobile phone, you'll need an unlock code. Call your cell provider's customer support to find out if your phone is locked or unlocked.  If it is a locked phone, ask if they will unlock your phone for international use.

• T-Mobile and AT&T use GSM technology (unlocked)

• Verizon and (soon) Sprint, have 4G LTE which is now a GSM standard (unlocked)

 

Buy a Local SIM Card.

With a GSM unlocked device, once you arrive at your overseas, you are ready to remove your existing cell company’s SIM card and replace it with one from a local mobile carrier at your international destination.  

You can buy a local SIM card at a kiosk at your arrival airport or find a local cellphone convenience store.  We purchased a 30 GB SIM card for $20 at a mobile convenience store while in Portugal and Spain. The newly installed international SIM card while only paying local rates. Simply insert in SIM card slot on your smartphone and activate. It's pretty simple and activates "automatico" with a few key prompts.  You can ask the mobile store representative for assistance. 

 

Downside To Using SIM Card

• You may get a new cell number.

• You'll have to change SIM cards as you travel to different countries.

 

Tablets With Cell Capabilities

If you have a 3G/4G tablet, check to see if it is or can be unlocked. Buy a data-only SIM card locally and use Skype or WhatsApp. You can also use the tablet as a hotspot, to share the connection among your other devices.

 

YOU CAN'T UNLOCK YOUR DEVICE

If your phone is not GSM supported and you can’t get it unlocked, you have other options. 

Roaming OFF shuts off all cellular data from sending or receiving on the networks (3G, 4G or LTE).  Even if you have cellular on just briefly after landing, data-hungry messages will flow through and make an expensive mistake in an instant.  If you need assistance, contact your provider's customer support and ask them to walk you through the steps on your specific device to ensure your device is set to Roaming OFF. You will still be able to receive phone calls and texts whenever you have WIFI or hotspot access at no cost. 

NOTE: While traveling, set your voice message to "I am currently roaming abroad, will reply when I am on Wi-Fi."

 

Disposable Phone

You may consider buying a cheap prepaid phone at your international destination then pass it forward to somebody else when you leave.

 

FREE WIFI IS AWESOME

WIFI Service. Your smartphone connection over Wifi is free. Plan on only using WIFI when available. The downside is finding available wifi service in other countries other than hotels and restaurants. It may be a slight inconvenience, but it's a lot cheaper.

 

You Can Wifi With WhatsApp

• Message your friends and family for free. 

• Make voice calls free to family and friends. 

• Have face-to-face conversations with family and friends for free. 

• Record voice messages to family and friends for free. 

• Send photos and videos to family and friends for free.

WhatsApp rules the industry for mobile users offering free and unlimited voice calling over a Wifi connection and not your cell plan's voice minutes. With nearly a billion smartphone users, no username or ID is required. Once WhatsApp is activated, your phone list is all that is needed.  

Before departing overseas, contact those folks you wish to stay connected with and confirm they use WhatsApp or agree to download WhatsApp. You can then enjoy live communication within a group even without an Internet connection or cellular network.
