SMS Length And Billing

Overview

An SMS will be billed as follows:

0 – 160 characters = 1 SMS (1 credit)
161 – 306 characters = 2 SMSs (2 credits)
307 - 459 characters = 3 SMSs (3 credits)

Calculation

To determine the length of the SMS and how many SMSes will be billed, the following calculation applies:

## Key: x = Number of characters (taking into account 7-bit and 14-bit) Math.Ceiling = Rounds up to the next full integer y = Number of SMSes to be billed Calculation: y = Math.Ceiling(x / 153) ## Example: Total length of characters is 340. Total length once we count the double characters. eg: “{}”, is 344. Divide this by 153 (344/153 = 2.248) and take the upper bound (ceiling) of 2.248 to equal 3. SMS will be billed as 3 SMSes.

Please note:

• The above calculation only applies if the SMS is greater than 160 characters in length.
• Maximum SMS length is 459 characters.
• SMSes longer than one SMS, i.e. 160 characters, in length are concatenated and display on the phone as one SMS.
• Anything longer than 459 characters will be truncated and billed as 3 SMSes.
