Receiving concatenated SMS

Module EG915U-EU with EG915UEUABR03A01M08_01.203.01.203 firmware.
Working with SMS in text mode.
When other side sends long SMS to module, it comes as 2 messages. Is it possible that module will concatenate it under the hood and show it as one long SMS with routed directly to the TE (AT+CNMI=2,2) using unsolicited result code: +CMT: ?

I can read SMS by AT+QCMGR and there are msg_seg and msg_total values so I would concatenate it in my device firmware, but my firmware use direct SMS displaying (AT+CNMI=2,2). It was working in M66 module. Now migrating to 4G and there is problem with concatenation (even if set it to 2G only) on this module.

From QNAvigator console:

[2023-06-09 10:31:50:930_R:] DSR:0 CTS:1 (RI:1) DCD:0

[2023-06-09 10:31:51:048_R:] DSR:0 CTS:1 (RI:0) DCD:0

[2023-06-09 10:31:51:731_R:] DSR:0 CTS:1 (RI:0) DCD:0

[2023-06-09 10:31:51:741_R:] t=0,in2Deact=0,in3Act=1,in3Deact=1

We need like this:
+CMT: “+48xxxxxxxxx”,“23/06/09,18:01:50+38”
#admin2,mod=+48yyyyyyyyy,vip=“admin2”,clip1=1,clip2=1,clip3=1,clip4=0,sms1=1,sms2=1,sms3=1,sms4=1,status1=1,status2=1,status3=1,in1Act=0,in1Deact=0,in2Act=0,in2Deact=0,in3Act=1,in3Deact=1

Hi @Jacek
LTE network supports longer text messages, have you tried sending them directly?

resolved in new module firmware.
