Knowing the SMS character limit is crucial for both personal and business messages. A single text can hold up to 160 characters, fitting into one GSM data packet. Yet, using emojis or special Unicode characters drops this limit to 70. This is because Unicode needs different encoding.
For texts longer than 160 characters, concatenated SMS is an option. But, this method may cause issues with delivery and raise costs. By understanding these limits, you can make your SMS marketing strategy work better. Shorten your messages using abbreviations and clear language. This way, your texts will be effective without costing more.
Understanding the Basics of SMS Character Limits
Sticking to character limits is key in SMS messaging. The standard limit comes from GSM data packet constraints. We have 160 characters to use in a single message.
Standard Limit for GSM Characters
The GSM’s 160-character limit relies on the GSM-7 encoding scheme. It fits in a 140-byte SMS data packet. This includes standard characters and symbols. But, using emojis or accented characters switches to UCS-2 encoding. This drops the limit to 70 characters per message.
Why 160 Characters?
The 160-character limit was carefully chosen. Friedhelm Hillebrand found that most short messages fit within this range. He looked at postcards and telegraph data. This research showed that 160 characters were usually enough.
Impact on Business Messaging
For businesses, knowing these limits helps in SMS campaigns. Messages must be short and to the point. Exceeding 160 characters means messages are split. This can cause extra costs and confusion.
Following SMS marketing rules is critical. This ensures messages are clear and powerful. They must fit within the character limits.
What Is the Size Limit for Text Messages
The SMS size limit is key for mobile communication. Normally, you can send 160 characters in a text. This includes letters, spaces, and punctuation. This limit helps make sure messages are short and clear.
If your message is longer, it will be split into several parts. Apps and phone services do this well, keeping your message’s meaning. This is crucial for SMS campaigns that aim to make an impact.
Unicode encoding also affects the SMS size limit. Special characters or non-Latin languages lower your character count to 70. This can change how effective your communication is.
Attachments in MMS messages have their own limits. For example:
- Average limit for SMS attachments among carriers: 300kb-600kb
- Tier 1 providers like AT&T and Verizon allow up to 3.5 MB.
- It’s best to keep attachments under 500KB for the best delivery.
Knowing these limits helps your messages get through. Twilio, for example, lets you add up to 10 attachments, but the total can’t be over 5 MB. This is great for SMS campaigns that include pictures or video.
Being aware of the text message character count and size limits is essential. This knowledge lets you send effective messages. By following these rules, your SMS campaigns will reach your audience as intended.
Unicode SMS: How Special Characters Influence Text Length
The type of characters you use impacts how long and well your text messages deliver. Knowing the difference between GSM and Unicode encoding can make your texts better. This is key for sending messages well.
Difference Between GSM and Unicode
GSM lets you use up to 160 characters. It works best for the regular alphabet. But if you add emojis or accents, you need Unicode. Unicode only lets you use 70 characters per text. That’s because it can handle different languages, like Arabic or Chinese.
Impact of Unicode on Character Count
Adding special characters cuts down how many letters you can send. GSM gives you 160 characters. But with just one special emoji or accent, you switch to Unicode. That drops you to 70 characters. Your messages might need to be split, which could cost more.
Examples of Unicode Characters
Unicode lets you use many unique characters. Examples include:
- Emojis like 😃, ❤️, or 👍
- Accented characters such as é, ü, or ñ
- Non-Latin scripts like ژ (Persian), 你 (Chinese), or Ћ (Cyrillic)
Using Unicode characters lets you send targeted and local messages. However, it limits you to 70 characters per text. So, planning your Unicode SMS is important to use your character limit well.

MMS and Concatenated SMS Messages

Advantages of MMS
MMS boosts what SMS can do. You can send videos, images, and audio along with text in messages up to 1,600 characters long. This is perfect for detailed and eye-catching messages, very useful for marketing. Tools like Textel help you keep an eye on your message size.
What is Concatenated SMS?
Concatenated SMS lets you send long texts by breaking them up. Normally, SMS can only hold 160 characters. If you go over, it splits the message into parts of 153 characters to ensure it all gets there. For instance, a message of 511 characters gets split into four parts. But, using emojis or special characters cuts the limit to 70 characters per part because they take up more space.
Potential Issues with Multipart Messages
Sending multipart SMS messages can have problems. Sometimes, parts of your message might not arrive, especially if networks don’t match up. Also, receiving many message pieces to put together might bother users. It can also be more expensive. Using tools to manage campaigns helps monitor costs and avoid surprises.
Knowing how SMS and MMS work helps in picking the right one for your message. The right choice can make your messaging more successful.
Conclusion

This limit can be broken into smaller pieces of 153 characters for sending. Going over this limit splits the message and may lead to people opting out.
Using special characters can also split messages, even if the text is short. This is very important for businesses to know. It helps to avoid unexpected costs and keeps messages clear. Also, MMS messages allow up to 1,600 characters and multimedia. But, they need the internet and can be costly.
