AT&T customers traveling abroad will now be able to access hundreds of thousands of additional hotspots.

The new international access comes as part of a deal AT&T struck with Spain's Fon, which claims to operate the world's largest Wi-Fi network. As part of the deal, AT&T customers can now access Fon's network of overseas hotspots, and Fon customers can tap into AT&T's Wi-Fi network, which includes more than 30,000 hotspots at restaurants, hotels, bookstores, and retailers across the U.S.

"Our agreement with Fon further expands our international Wi-Fi footprint making it easier for AT&T customers to stay connected to what matters most during their travels abroad," AT&T vice president of partnerships and alliances, JR Wilson, said in a statement.

But this expanded access will, of course, come at a hefty price. AT&T customers who wish to access the Fon hotspots will need to add a 300MB or 800MB global data package to their wireless plan, which will cost $60 or $120, respectively. After doing so, users are allocated 1GB of Wi-Fi each month before getting hit with overages.

Those who are OK with the price can access the hotspots through AT&T's Wi-Fi International App, which is available for iPhone, iPad, and Android devices. The agreement covers smartphones and other Wi-Fi-enabled devices.

Earlier this year, AT&T inked a similar deal with Boingo, which provided AT&T customers with access to Boingo hotspots in international airports, but it came with the same service plan requirements.

The new international access comes after AT&T earlier this month completed its $1.9 billion acquisition of spectrum from Verizon Wireless. The arrangement was first announced in January, and is intended to help AT&T's rollout of its 4G LTE network, which has now launched in 405 markets.
