SMS from Gmail in India

Google has added option to send SMS from Gmail in India.
Here is the steps to follow:

You can send SMS messages to your contacts’ mobile phones using Gmail Chat. To do so from Gmail:

  1. Enter your contact’s name in the ‘Search or invite friends’ box in Chat, and select Send SMS from the box of options that appears to the right of your contact’s name. Or, if you already have a Chat window open for this contact, just click Options, and select Send SMS.
  2. In the dialog box, enter a phone number in the ‘Send SMS messages to this number’ field. This feature is only launched in selected countries. Click here for the list of supported countries and operators. If you are not located in one of these countries you can still use it, but you won’t see the SMS option in Chat until you enable it manually in the Chat settings page.
  3. Click Save.
  4. A Chat window appears. Just type your message as you would normally. When you hit Enter, the message will be sent to the phone number you entered.

Message Limit:

They give 50 Message credit. the exact details are below:

SMS credit is an allocation of SMS (text messages) that you’re able to send to a mobile phone:

  • Initially, you’re granted a credit of fifty messages.
  • Every time you send a message, your credit decreases by one.
  • Every time you receive an SMS message in Chat (for example when a phone user replies to one of your messages) your credit increases by five, up to a maximum of 50.

If your SMS credit goes down to zero at any point, it will increase back up to one 24 hours later. So, you won’t ever be locked out of the system.

 Supported mobile operators in India:

All Mobile operators in India are supported for this feature. Initially major operators like Airtel & BSNL were not present. Looks like Google has come to agreement with them and every operator is supported.

What happens when reach the SMS limit:

Keep in mind that if you’d like a higher message credit, you can always send an SMS to your own phone, and then reply to that message multiple times. Every time you send a reply message, your SMS credit is increased by five. Effectively, you’re buying more messages by paying your phone company for these outgoing messages.
