SIM900 MMS AT Command Manual 1 Introduction This document presents the AT command of MMS operation for SIM900. This document can apply to the same series of the modules which contain MMS function, like SIM900, SIM900D, SIM900B and SIM900A. 1.1 Features 1. SIM900 supports sending and receiving MMS only through HTTP protocol. 2. Unicode (both little endian and big endian) and UTF8 are character sets supported and ASCII is supported only for English and numerals. 3. The maximum data size of an MMS is 300 Kbytes.. 4. The maximum size of an image file is 300 Kbytes. 5. The maximum size of a text file is 15360 bytes. 6. The maximum number of files to be enclosed is 10. 7. 8. 9. It is necessary to input text data into modem with header of Unicode (both little endian and big endian, “FF FE” is the header for Unicode little endian and “FE FF” is the header for Unicode big endian) It includes “MMS PUSH” in “+CMTI: …” when the received short message is a MMS push message (either M-Notification.ind or M-Delivery.ind [2]). If the current received MMS push message is a concatenated message, it will include “,,” after “MMS PUSH”. is the total number of the parts of the concatenated message and is the index of the current part in the whole concatenated message. For example: + CMTI: "SM",1,"MMS PUSH",2,1. In the URC, 2 means the concatenated push message include two parts and 1 means the current message is the first part. When all the parts of the concatenated push message have been received, it will prompt “+CMTI: …” URC with “MMS PUSH” and without “,,”. For example: +CMTI: "SM",1,"MMS PUSH" 10. X-profile parameters need to be configured for some MMS server, or some problems like image compression error may occur, also the x-profile address which is not configured by default should be set according to the customer’s own hardware environment. 11. The output text from the modem is encoded with little endian Unicode, but the head of Unicode is omitted. 1.2 Reference [1] SIM900 AT Commands Set [2] wap-209-mmsencapsulation-20020105-a SIM900_MMS_AT Command Man1ual_V1.00 4 2010.11.15
