AT&T announced its new International Day Pass on Monday. The pass cannot be purchased separately, but is a feature you can enable on your existing AT&T devices.

The International Day Pass will let you use your data plan in over 100 countries, apart from offering unlimited voice calls and text messages at a cost of $10 per day per device in countries listed by AT&T. The feature will be rolled out starting Friday, and will replace AT&T’s Passport plan, which cost $40 a month for 200MB of data.

David Christopher, chief marketing officer, AT&T Entertainment Group, said in the official press release: “Traveling has its own challenges. It’s great being able to use the domestic plan you’re familiar with while abroad.”

Once enabled, the feature will stay on your device till such time as you choose to remove it. It will let you make calls from the U.S. to the listed countries and vice-versa. As the pass is sold per device, it would be advisable to buy separate passes for each member if you are on a family plan.

The pass, though comes with a rider — the feature may be removed if international calls, text or data usage exceeds 50 percent of total calls, text or data usage for two consecutive months.

In comparison to the AT&T International Day Pass, Sprint offers an International Speed Data Roaming day pass which provides 100MB unrestricted data, unlimited texting and 20-cent per minute calling in the countries covered by its Global Roaming Agreement. Verizon offers a similar feature called TravelPass, which costs $10 a day for talk, text and data in more than 100 countries.
