How SMS credits are counted
A standard English SMS (GSM-7) holds 160 characters. Longer messages are split into parts of 153 characters each. Messages with Hindi, regional languages or emoji use Unicode: 70 characters for one SMS and 67 characters per part after that. Each part uses one SMS credit for every recipient.
Some symbols such as { } [ ] ~ | € count as two characters in GSM. For a detailed character-by-character view, use our SMS character counter. Bulk SMS price depends on the route and volume, so ask our team for a quote once you know your total credits.
Frequently asked questions
How many characters are in one SMS?
One English (GSM) SMS holds 160 characters. A Unicode SMS, used for Hindi and regional languages, holds 70 characters.
How are long SMS credits counted?
Long English messages are split into 153-character parts and Unicode messages into 67-character parts. Each part uses one credit per recipient.
Does a Hindi SMS use more credits?
Yes. Hindi and other Unicode messages fit fewer characters per SMS, so a long Hindi message usually uses more parts than the same message in English.
Do {#var#} placeholders count as characters?
The calculator counts the text you enter. When you send, the real values replace {#var#}, so count with realistic sample values for an exact result.
