How to Send a Free SMS with Airtel

1. Locate your text message's settings in your phone's main menu.
2. Locate a free message center number for Airtel, such as '+919810051905' to gain access. Enter this number into your phone. Save the number in packet data as the 'Preferred Connection Type.'
3. Click 'Save.' Go to 'Settings, Phone Settings, Connection, Packet Data.' Under this, click 'When Available' for Airtel. Click 'Save.'
4. Send an SMS message. Since the Airtel service resides overseas, you need to enter a 0 preceding the number you wish to text. For example, 248-583-1234 would be 0-248-583-1234.
