How Omnisend’s SMS calculator helps

Omnisend’s SMS calculator highlights every character in your message, so you can see what affects your length. Grey characters are standard GSM, green ones are special GSM characters that count as two, and red ones switch your message to Unicode.

Why SMS character count matters

One SMS credit equals 160 characters

A standard text message using the GSM-7 alphabet holds up to 160 characters. Go over that, and your message splits into segments of 153 characters each.

Emojis cut the limit to 70 characters

Adding an emoji or a non-Latin character switches your message to Unicode, which holds only 70 characters per credit. Keep these messages extra short to stay within one credit.

Keep your sending costs in check

Every extra segment counts as another credit. A message that spills over the limit by just a few characters costs twice as much to send, and a long one can cost three times as much.

Keep your message easy to act on

Short texts get to the point faster. A long message that runs across several segments can bury your offer or link, so shoppers are more likely to miss what matters.

GSM vs. Unicode encoding: what’s the difference?

GSM

GSM-7 is the standard SMS encoding for English and most Western languages. A GSM message holds up to 160 characters before it splits into segments.

Unicode

Unicode covers every language, plus emojis and special characters. The trade-off is space: a Unicode message holds only 70 characters before it splits.

Feature	GSM-7	Unicode
Character count	160 before segmentation	70 before segmentation
Multipart messages	Splits into 153-character segments due to a User Data header	Splits into 67-character segments due to a User Data header
Supported content	Latin letters, numbers, standard symbols	All languages and emojis
Why it matters	Cheaper for everyday messaging, ideal for longer texts provided you’re happy with standard characters	Needed for emojis and many languages, but splits into segments sooner
What to watch out for	Some symbols, like €, {, }, [, ], ~, ^, \, and \|, count as two characters toward your 160 limit	Any non-GSM character, like an em dash, curly apostrophe, accented letter, or emoji, switches the whole message to Unicode

FAQ

How many characters are in one SMS?

One SMS holds up to 160 characters when your text uses only standard GSM-7 characters: Latin letters, numbers, and common symbols. Add an emoji, an accented letter, or another Unicode character, and the limit drops to 70. A few symbols, like € or [ ], count as two characters each.

Why is my text message split into 2 SMS?

Your message went over the limit for one SMS: 160 GSM-7 characters or 70 Unicode characters. Longer texts are sent in parts of 153 or 67 characters, because each part keeps a little room to join the message back together on the phone. Each part is billed as one SMS.

Do emojis use more characters?

Yes. A single emoji switches the whole message to Unicode, so the limit drops from 160 to 70 characters per SMS, and longer messages split into 67-character parts. If your text is close to the limit, one emoji can turn a single SMS into two or three.

Do spaces count as characters?

Yes. Every space, line break, and punctuation mark counts toward the limit. Double spaces are easy to miss, and each one costs you a character, so check for them before you send.

Does the opt out text count toward the character limit?

Yes. The opt out text is part of the message, so it counts toward the limit. Omnisend’s default, “Reply STOP to opt out,” uses 21 of your 160 characters, so plan the rest of your message around it.

How much does it cost to send an SMS with Omnisend?

It depends on the country you’re sending to and your monthly volume. In the United States, an SMS costs $0.007–$0.009, and the price drops as you send more. Each part of a longer message is billed as one SMS. See every rate on the Omnisend SMS pricing page.

Which Omnisend plans include SMS?

SMS is available on the Pro plan. You pay for the SMS you send, and the price per message depends on the country and your monthly volume. Compare what each plan includes on the Omnisend pricing page.
