Hello, I would like to confirm if our SMS module supports sending long SMS messages ？

Description

Hello, when I was testing the SMSC SMS business, I found that the SMS could not be forwarded by the SMSC when the characters were too long, approximately 117 characters. The issue was traced back to the smsops module, which has a limit on the length of the SMS, but it seems that it does not handle SMS segmentation. The error message returned is as follows. Could you please provide some suggestions and help?
