One SMS shall be of 160 characters in length. A lengthier message can be sent using a concatenation process where we use special characters to join the SMS and deliver them as one message. Due to the use of characters to join the messages there shall be few inconsistencies in the length of SMS. Below is detailed information on message lengths and the respective costing method:
Number of SMS Characters
1 message = 160 characters
2 messages = 306 characters
3 messages = 459 characters
4 messages (Maximum) = 612 characters
If you send 10 messages that are of 160 characters falling under 1 SMS length, you will be charged for 10 messages only, similarly if you send 10 messages that are of 306 characters falling under 2 SMS length, you will be charged for 20 messages.
Each line break, space and carriage return adds to your character count. For instance, 1 space = 1 character 1 line break = 2 characters.
SMS can be sent 24x7 and will be delivered on DND and as well as NON DND numbers. Auto-selected numeric sender ID will be masked as sender as per TRAI regulation. We have got approval to send any type of SMS for which no template is required.
