Hi,
The maximum length of a single short message is 152 characters. You can send 150 characters in one short message. The following AT logs illustrates to send 150 characters in one short message.

Do you use PDU or Text mode and what type of charter set?
Could you please provide us AT logs with firmware version as follows?

CMS ERROR: 226 means “SMS connection broken”.
This issue can be related with GSM network (poor signal, service provider structure etc.). Did you try with the different service provider SIM card or different antenna?
It is needed to check Chipset logs of the module to analyze the network related issues.
Please contact our local FAE to get the log tool and they will help to analyze the reason.
You also can send email to support@quectel.com to get the support from local FAE.

No. I did not yet. Oke i will try with different provider SIM first and if problem did not solved yet, i will contact FAE. Thank you for your help
