In 2002, Starbucks started providing hotspot services, through T-Mobile, as a free initial trial at around 1,200 US stores, with subsequent charges on a prepaid, pay-as-you-go, and monthly basis. The coffee chain then switched its network to AT&T at its 7,000 US stores in 2008 and started offering two free hours of Wi-Fi access per day to Starbucks Card holders.
