Stay connected with friends and family back home when you're travelling abroad.

Travelling overseas can be expensive as it is, and that's even without considering how to get the most out of your phone when calling, messaging or using data abroad.

If you're between carriers and want to know the absolute best deal available for international data roaming, we've got you covered with our roundup of the four major carriers' offerings. If you're already an an AT&T customer, you'll be happy to know that they offer three different international wireless plans at different price points featuring sliding pay-per-use rates. Just like you wouldn't go anywhere without your passport, you shouldn't travel and text without your AT&T Passport.

What are AT&T Passport plans?

AT&T offers three tiers of international wireless plans for customers travelling overseas.

Whether you're just going on a short trip, or spending months backpacking through Europe, you should figure out how important calling and data rates are to you — you won't have to worry about texts, as all three plans include unlimited texting.

The three levels are AT&T Passport, Passport Silver and Passport Gold. We've also included the pay-per-use rates if you want to compare whether it's even worth buying a plan, based on how much you expect to be using your phone during your travels.

You can check the full list of participating countries provided by AT&T here, but we've done the busy work for you and compiled a list of participating Passport Wi-Fi countries below. Also note that you revert to standard International pay-per-use rates if you're in a country AT&T does not support, or if you let your Passport plan expire while still travelling abroad.

International plans for laptops and tablets

If you travel with a laptop or tablet and want to use it wherever you go, AT&T also offers pure data plans for those devices at the exact same rates for phones, except without the texting or calling features.

AT&T Passport

  • $30 (one-time for 30 days, or recurring monthly)
  • 120MB of included data ($0.25/MB for overage)

AT&T Passport Silver

  • $60 (one-time for 30 days, or recurring monthly)
  • 300MB of included data ($0.20/MB for overage)
  • Unlimited Wi-Fi access at participating hotspots

AT&T Passport Gold

  • $120 (one-time for 30 days, or recurring monthly)
  • 800MB of included data ($0.15/MB for overage)
  • Unlimited Wi-Fi access at participating hotspots

Note that if you want to use your phone and a laptop/tablet, you would need to buy a plan for both devices separately.

Mexico Roaming Bonus

If you regularly travel to and around Mexico and already have an AT&T Unlimited, Mobile Share, or Mobile Share Value wireless plan, you should consider adding AT&T Mexico Roaming Bonus to your account to access unlimited talk (within Mexico and from Mexico to the U.S.), unlimited texting and 1GB of roaming data when in Mexico ($20/GB for overage).

It's free to add to your account if you have one of the plans mentioned above, but must be added to each device on your plan individually. Furthermore, if you've added AT&T Passport to your wireless plan, you don't have to worry about Passport data rates applying when you're in Mexico.

As per the fine print, restrictions may apply and service/coverage might not be available everywhere. Contact AT&T customer service for more information.

Wireless plans for cruise ships

Hitting the high seas on a Caribbean cruise, but still want to stay in touch with your family and friends back home? AT&T has plans that allow you to talk, text or use data while at sea or on land in Canada, Mexico, or 28 Caribbean island countries. Whether you just want the freedom to check in back home every couple of days or data to check emails and make people Insta-jealous on social media, AT&T's got a plan for you.

First, check to make sure your cruise ship is supported by AT&T coverage, then compare to the pay-per-use rates to see if getting a cruise package makes sense for you and your family.
