How Bulk SMS Works in India
Everything you need to know about SMS character counting, Unicode languages, and API integration.
Understanding SMS Character Limits & Multiparts
SMS credits are calculated on the character count of your text and the character encoding used. Telecom operators distinguish strictly between Standard English (GSM-7) and Regional Languages (Unicode).

160 CharsIncludes standard Latin letters, numbers, and basic punctuation.
- Part 1: Up to 160 characters (1 SMS credit)
- Part 2: Up to 306 characters (2 SMS credits)
- Part 3: Up to 459 characters (3 SMS credits)
- * Multipart SMS reserves 7 characters per part for user-data headers (UDH).
Unicode & Regional (UCS-2)
70 CharsUsed for Kannada, Hindi, Tamil, Telugu, Malayalam, and special emojis.
- Part 1: Up to 70 characters (1 SMS credit)
- Part 2: Up to 134 characters (2 SMS credits)
- Part 3: Up to 201 characters (3 SMS credits)
- * If a single Unicode character is present, the whole message converts to Unicode.
