SMS Length Calculation Rule

SMS length = number of characters in the signature + number of characters in the body. A single SMS message can contain up to 500 characters.

Signature is optional for global SMS.

SMS containing English characters only

• A standard GSM character is calculated as 1 character, while an extended GSM character is calculated as 2 characters.

• If an SMS message contains 160 characters or less, it will be billed as one message; otherwise, it will be billed as multiple messages based on the standard of 153 characters per message.
  For example, if an SMS message contains 320 characters, it will be billed as 3 messages (153 + 153 + 14 characters).

SMS containing non-English characters

• One Chinese character, letter, digit, punctuation mark (both fullwidth and halfwidth forms), or space will be calculated as 1 character.
• If an SMS message contains 70 characters or less, it will be billed as one message; otherwise, it will be billed as multiple messages based on the standard of 67 characters per message.
  For example, if an SMS message contains 150 characters, it will be billed as 3 messages (67 + 67 + 16 characters).
