What is the character limit for SMS text messages?
The standard length for “text” messages is 160. The 160-character limit is set for messages encoded using the GSM-7 character set. Longer messages are split into 153-character ‘segments’ and sent individually, then re-assembled by the recipient’s device. For example, a 161-character message will be sent as two messages: one with 153 characters and a second with eight characters.
If your message includes non-GSM characters (Unicode Characters), such as special characters, or vernacular languages for e.g. Hindi or Chinese script, they are sent using UCS-2 encoding. Length of such messages are limited to 70 characters. Longer messages will be split into 67-character segments.
Using single API Post, you can send up to 1537 characters long message which will in turn be broken into segments. Each message segments are delivered as single SMS. Therefore, you will be billed for each of these “segments” or “parts” sent.
Refer the following table as reference to know how a single message posted using API will be split into multiple segments and get billed for:
|API posted GMS Message Length||API posted Unicode Message Length||Total Segments you pay for|
|1 – 160||1 – 70||1|
|161 – 306||71 – 134||2|
|307 – 459||135 – 201||3|
|460 – 612||202 – 268||4|
|613 – 765||269 – 335||5|
|766 – 918||336 – 402||6|
|919 – 1071||403 – 469||7|
|1072 – 1224||470 – 536||8|
|1225 – 1377||537 – 603||9|
