Starbucks and Wi-Fi, now the combination is on, as the coffee giant and AT&T officially launched the service in Starbucks stores in San Antonio. The two partners promised to continue the Wi-Fi campaign across the U.S. all throughout the next month.

The service was first announced in February this year, when Starbucks ended a partnership with T-Mobile and started a brand new one with AT&T, promising to offer consumers Wi-Fi connectivity in all the 7,000 Starbucks locations in the U.S.

"With the power of our Wi-Fi network, and through our partnership with Starbucks, we're strengthening our ability to meet the needs of today's mobile consumer virtually anywhere and everywhere," said chairman and chief executive officer Randall Stephenson.

He added: "Expanding our reach across company-operated Starbucks locations nationwide helps us bridge the gap between our wired and wireless offerings and affirms AT&T's commitment to connect people with their worlds, everywhere they live and work." Costumers will be able to use the service by selecting “ATTWiFi” from their computers.

In February this year, AT&T unveiled that customers who will buy the Starbucks purchase card will receive two hours of free wireless access. Those who want more than two hours have two options. They could buy another additional two hours for $3,99 or a monthly membership which costs $19.99 and includes access to any of AT&T's 70,000 hot spots in 89 countries around the world.

"We continue to build on the experience we know our customers expect from us," said Chris Bruzzo, chief technology officer, Starbucks. "By partnering with AT&T as our U.S. Wi-Fi provider we aim to deliver a better value, greater convenience and seamless connectivity in a mobility centric world to our customers."
