When communicating with your customers, keeping your messages concise is key to ensuring they are read and acted upon. If you are wondering what is a good character count for a text from a business, the short answer is between 100 and 150 characters. This length ensures your message fits within a single standard SMS segment, keeping your costs low and your readability high.
The Golden Rule of Business SMS Length
For most local businesses—like dental clinics, auto repair shops, beauty salons, and tutoring centers—SMS is the most direct way to reach clients. However, the technical backend of SMS communication imposes strict limits on how many characters you can send before your message gets split, costing you double or triple your expected budget.
The standard industry limit for a single text message is 160 characters. If an sms message over 160 characters will be split, it is divided into multiple parts (segments) by telecom carriers. When this split occurs, each part is billed as an individual message. To make matters worse, the headers required to stitch those split messages back together on the recipient's phone reduce the limit of each subsequent segment to 153 characters.
Therefore, a good character count for a text from a business is 100 to 150 characters. This gives you enough room to convey your message, include a clear call-to-action (CTA), and leave a safe buffer so you do not accidentally spill over into a second billed segment.
The Technical Breakdown of SMS Segments
When you send an SMS, it is encoded using one of two standards: GSM-7 or Unicode. GSM-7 supports standard English letters, numbers, and basic punctuation. Under GSM-7, your limit is a strict 160 characters. If you exceed this, the billing system splits your text. If you send 0 characters, you get 0 messages sent, but as soon as you type character 161, you are paying for two segments.
GSM-7 vs. Unicode: The Hidden Character Killers
Many business owners write a message, check their character count, see it is 120 characters, and assume they are safe. Then, they look at their monthly bill and realize they were charged double. Why does this happen? The answer lies in special characters in message encoding.
If you use a single non-GSM character—such as an emoji, a curly quote, or accented letters common in other languages—the entire message is forced into Unicode encoding. When this happens, a warning message similar to the one from Voicesage is triggered: you are sending a unicode message, this will decrease your character limit per message.
Under Unicode, your single-message limit drops from 160 characters to just 70 characters. If your message is 71 characters, it splits into two segments (billed at 67 characters per segment due to concatenation headers).
What Are Smart Characters in SMS?
Many modern keyboards and text editors automatically convert standard straight apostrophes (') and quotation marks (") into curly "smart" punctuation. In the telecom world, these are known as smart characters. Because these are not part of the standard GSM-7 alphabet, they are classified as sms with special characters. This instantly slashes your limit to 70 characters. Always check your text editor settings to disable smart punctuation before sending campaigns.
Special Characters Which Causes Issues in SMS Messages Sending
Certain symbols like emoji, non-Latin alphabets (Cyrillic, Arabic, Greek), and specific mathematical symbols are common special characters which causes issues in sms messages sending. Even a simple accented character can trigger Unicode encoding. In French, this is often referred to as the 140 character enlever des sms issue, where developers try to strip accents to fit messages within the standard byte limits (140 bytes of payload, which equals 160 7-bit characters or 70 16-bit Unicode characters).
The Ideal Character Count by Business Use Case
Depending on what you are communicating, your target length will vary. Here is a breakdown of common operational notifications sent by service businesses, along with their ideal character counts to maximize engagement and minimize costs.

How Standard SMS Gateways Bill You for Long Messages
Traditional A2P (Application-to-Person) SMS providers like Twilio, Plivo, and MessageBird bill you strictly per segment. If your message is 161 characters, you pay for 2 messages. If your message contains Unicode characters and is 72 characters long, you pay for 2 messages. This makes writing SMS campaigns a stressful exercise in counting characters and stripping out natural language.
Additionally, traditional gateways require complex brand registrations, A2P 10DLC compliance fees, and carrier approvals, making them highly impractical for local businesses outside the US who just want to send simple notifications to their existing customer base.
This is where MySMSGate offers a massive advantage. Instead of billing you per 160-character segment, MySMSGate charges a flat rate of $0.02 per message regardless of length or character encoding. Because the system routes messages through your own connected Android phone and SIM card, there are no segment-splitting penalties, no carrier registration delays, and no hidden fees.
Comparison: Traditional API vs. MySMSGate
With a traditional sms api, sending a 200-character promotional message with an emoji to 500 customers would require 3 segments per message (70 characters per segment for Unicode). That is 1,500 billed segments. At an average rate of $0.0079 per segment plus carrier fees, your cost quickly escalates. With MySMSGate, those same 500 messages cost a flat $10.00 (500 messages x $0.02) because we charge per physical message sent, not per segment.
Best Practices for Writing Business Texts
To ensure your messages are highly professional, readable, and delivered successfully, follow these standard industry rules:
- Identify Your Business Immediately: Start your message with your business name so the customer knows who is texting them.
- Keep CTAs Clear: Use direct action words like 'Call us at,' 'Click to confirm,' or 'Reply to reschedule.'
- Watch Your Links: If you need to include a URL, use a clean domain. Avoid generic link shorteners like bit.ly, as they are often flagged by mobile carriers as spam.
- Understand Masking Rules: Be aware of masking characters in sms rules if you are sending sensitive information like temporary passwords or partial account numbers. Always mask sensitive data (e.g., 'Your code is 48xx72') to protect customer privacy.
- Avoid Attachments Unless Necessary: Standard SMS does not support attachments. If you need to add attachment files, upload them to your web server and include a short link in the SMS.

How to Handle Character Limitations When Leaving a Message
When your customers reply or when you need to leave an automated status update, keep in mind the character limitations when leave a message on their lock screens. Most modern mobile operating systems, including Android and iOS, only display the first 100 to 120 characters of a notification. Placing your most critical information—such as the appointment time or the verification code—at the very beginning of the message ensures the recipient sees it instantly without even needing to unlock their device.

Frequently Asked Questions
Here are some of the most common questions business owners and developers ask about SMS character counts, carrier rules, and message limits.
What is the standard SMS character limit for business texts?
The standard limit is 160 characters for messages using GSM-7 encoding (standard Latin characters). If you use any special characters, emojis, or non-Latin scripts, the limit drops to 70 characters due to Unicode encoding rules.
Why did my 161-character text bill as two messages?
Standard telecom carriers and APIs bill per segment. Since a single GSM-7 segment is 160 characters, any message that is 161 characters or longer is split into two or more segments and billed accordingly. With MySMSGate, we charge a flat $0.02 per message regardless of segment count.
What are smart characters in SMS and how do they affect limits?
Smart characters are curly quotes, decorative apostrophes, and other non-standard symbols automatically generated by word processors and mobile keyboards. Because they are not part of the standard GSM-7 alphabet, they force your text into Unicode encoding, reducing your single-message character limit from 160 to 70 characters.
Can I receive replies to my business texts using MySMSGate?
Yes! When you use an android sms messaging and communication platform like MySMSGate, any incoming texts sent to your phone's SIM card are automatically forwarded to your web dashboard in real-time. This allows you to have two-way conversations with your customers directly from your computer browser.
