Role of SMS Credit in Chat:
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.
"Buying" additional messages
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.
