SMS message length and encoding issue

Tohid4 days ago

Hello,

I'm using a custom WordPress plugin to send SMS messages through your Traccar SMS Gateway. Messages with up to 160 characters are sent correctly, but any message longer than that either gets cut off or is not delivered.

Could you please clarify the following:

  1. What encoding format does the SMS gateway use? (GSM-7, Unicode/UCS-2, etc.)

  2. Does it support multipart SMS for messages longer than 160 characters?

  3. Is there a specific setting or parameter to enable long message support?

  4. Is there a character limit when using Unicode or non-GSM characters?

This will help me ensure compatibility between my plugin and your gateway.

Thanks in advance for your help!

This is completely unrelated to Traccar Manager.

Thanks for the clarification.

Could you please tell me which exact method your SMS gateway uses for sending messages?
For example, do you use:

SmsManager.sendTextMessage()

SmsManager.sendMultipartTextMessage()

GSM 7-bit encoding

UCS-2 (Unicode) encoding

Knowing this will help me adjust my plugin accordingly to ensure compatibility with your system.

Thanks again for your help!
