Standard SMS alphabet: 160 characters in one SMS, 153 per part once it splits.

Why counting characters saves money

Every SMS part is billed separately. A 161-character message costs twice as much as a 160-character one, and a single emoji can cut a message from 160 characters to 70, tripling the cost of a long campaign. Checking before you send keeps every message in as few parts as possible.

Frequently asked questions

How many characters can one SMS hold?+

160 characters if the message only uses the standard GSM-7 alphabet, or 70 if it contains any Unicode character such as an emoji, a curly quote or a non-Latin letter.

Why does my long SMS count as more than one message?+

Messages over the single-SMS limit are split into parts that the phone joins back together. Each part loses a few characters to joining information, so parts hold 153 GSM-7 characters or 67 Unicode characters, and every part is billed as one SMS.

Why does my message suddenly allow only 70 characters?+

One character outside the GSM-7 alphabet switches the whole message to Unicode. The usual culprits are emoji and the curly quotes, long dashes and ellipsis that word processors insert. The counter lists them and can swap them for standard characters.

Do some characters count as two?+

Yes. In GSM-7 these count as two characters each: ^ { } \ [ ] ~ | and €. In Unicode, most emoji count as two.

Does a space count as a character?+

Yes. Spaces and line breaks each count as one character.
