SMS Character Counter
Free SMS character counter tool. Calculate message length, detect GSM-7 vs Unicode encoding, count SMS segments, and estimate cost before sending.
How do I count SMS characters?
Use our free SMS character counter to instantly calculate your message length, detect GSM-7 vs Unicode encoding, and see how many SMS segments your message will use. Standard SMS supports 160 characters with GSM-7 encoding or 70 characters with Unicode. Messages longer than these limits are split into multiple segments, each billed separately.
What is SMS Character Counter?
SMS Character Counter is a free online tool that helps businesses and marketers calculate the exact character count of their text messages before sending them through bulk SMS platforms. It detects whether your message uses GSM-7 (standard Latin characters) or Unicode (special characters, emojis, non-Latin scripts) encoding, which directly affects how many characters fit in a single SMS segment — 160 for GSM-7 and 70 for Unicode. The tool also calculates how many SMS segments your message will be split into, helping you estimate costs and optimize message length.
How It Works
Simply type or paste your message into the text box. The tool automatically analyzes each character in real-time, identifies the encoding type (GSM-7 or Unicode), counts total characters, calculates remaining characters before the next segment, and shows the total number of SMS segments your message will consume. This helps you optimize message length to stay within budget and avoid unexpected multi-segment charges.
Why Businesses Use It
Businesses use SMS Character Counter to avoid overspending on multi-segment messages, ensure DLT-compliant messaging, optimize promotional campaigns for maximum impact within character limits, test transactional SMS templates before deployment, and verify Unicode content for regional language campaigns across India.

Frequently Asked Questions
What is the SMS character limit?
Standard SMS uses GSM-7 encoding with a 160-character limit. If your message contains Unicode characters (emojis, special symbols), it switches to UCS-2 encoding with a 70-character limit per segment.
How are long SMS messages billed?
Long messages are split into segments. Each segment is billed as one SMS. GSM-7 messages over 160 characters are split into 153-character segments. Unicode messages over 70 characters are split into 67-character segments.
What is GSM-7 encoding?
GSM-7 is the standard character encoding for SMS. It supports Latin letters, numbers, and common symbols. If your message contains characters outside this set (like emojis or regional scripts), it automatically switches to UCS-2 encoding.
How can I reduce SMS segments?
Avoid Unicode characters and emojis. Use standard ASCII characters. Keep messages concise. Use URL shorteners for links. Remove unnecessary spaces and line breaks.
