Hello an44, thanks for your question
According to the content of your question, I guess that short messages can be received, but long messages cannot be received. If you want to send long text messages, you can execute AT+QCMGR command to send Concatenated messages. For details, please refer to Chapter 9.18 of AT Command Manual. If you want to send MMS, you can refer to the attached document, thank you. Quectel_LTE_Standard_MMS_Application_Note_V1.1.pdf (316.9 KB)
