SMS credit in Chat (SMS Credit: 50)
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.
Note: Send SMS via Gmail Chat. You will be credited Rs.50 for free. When I sent one SMS through Gmail SMS Chat they charged me Re.1. It’s free. Try it now.
