Why are older phones better for sending messages? I own two phones. The first is the S24 Ultra, and I can insert two physical SIM cards. When I want to send a text message, I'm only allowed to write 5 lines in Arabic. If I write more than that, the phone system automatically converts it to multimedia messages. The other phone is the Samsung Note 20 Ultra, and I can also insert two physical SIM cards. I can send 11 lines in Arabic. What is this, Samsung? What is this, Samsung?

Older phones aren’t actually better this happens because Arabic text uses Unicode (UCS-2), which allows only about 70 characters per SMS, and newer Samsung phones like the S24 Ultra are stricter about this and convert long Arabic messages to MMS much earlier (around 4–5 lines) to avoid delivery and billing issues with concatenated SMS, while older models like the Note 20 Ultra allowed multiple joined SMS parts, letting you write more lines before switching to MMS; it’s a software policy change by Samsung, not a hardware problem.

Is there a solution to writing more than 5 lines?

[MrTabii]

you can write more by using enabling RCS (Chat Messages) in Samsung Messages, or switching to Google Messages which handles joined Arabic SMS better, avoiding emojis and special symbols, or manually splitting the text into multiple SMS; there is no full fix inside Samsung Messages on newer models because it’s a Samsung software policy, not a SIM or network issue.

Thank you for providing me with the information 🙏

Thank you for contacting us. We understand your concern regarding the difference in SMS message length between your Galaxy S24 Ultra and your older Galaxy Note20 Ultra.

Please note the following:

• SMS character limits depend on carrier policies, encoding, and device software.
• When typing in Arabic, the phone uses Unicode encoding, which reduces the number of characters allowed in a single SMS before it converts automatically to MMS.
• On newer devices, some carriers apply stricter SMS size limits, which can cause the message to convert earlier (for example, after 5 lines).
• Older models may have used a different encoding or carrier profile, allowing more lines before conversion.
• This behavior does not indicate a defect in your S24 Ultra. It is related to updated carrier restrictions and encoding standards on newer software versions.

If you would like us to check your device settings or confirm your carrier profile, you are welcome to visit the nearest Samsung Service Center:
