To connect to Starbucks' wireless internet, first locate the Wi-Fi network (e.g., "at_STARBUCKS_Wi2" or "Tata Docomo Wi-Fi") in your device's settings. Then, open a web browser and navigate to any website. This should redirect you to the Starbucks Wi-Fi login page, where you can accept the terms of use. If you're in India, you might be directed to a page where you must provide your name, email, and mobile number to receive a serial number and PIN. Enter these details to complete the connection.
