simcom modules firmware collection

Here I am trying to make a collection of firmware (simcom modules firmware) and release notes for Simcom Sim900 and other Simcom GSM/GPRS modules

You may upload the files that you have to share with others and they would be available in the user Uploads folder below. I may filter them time to time and put them in the relative folders.

  1. Hi Sir, I need help with +HTTPACTION:0,601,0 problem My Seedstudio Sim900 board came originally with 1137B13SIM900M64_ST firmware. There was no HTTPS support so I flashed my module with SIMCOM_SIM900 Revision:1137B06SIM900M64_ST_ENHANCE firmware with help from your site. Thank you very much by the way. Now while trying to connect using HTTPS I get the above error (Network error according to command manual). all HTTP requests are successful though when I disable HTTPS. From what I’ve been hearing after searching online for a solution is that this could be a redirect. Others say after putting a bit more credit/data on sim card it works. If the problem is network related why are http requests working? Also when I put the sim card in my phone I can browse https sites. Should I try a different ‘enhance’ firmware or is it a URL problem? When I try to intentionally put a bad URL I get a different error – 603 (DNS Error), which is correct. Can HTTPS work on my phone bowser but not on the sim900 module, or is there a step I’m missing? Please advise.

    • Status codes above 600 (and some in the 500 range) are unassigned in the HTTP standard. In the AT command manual , status meanings are given in the notes on the HTTPACTION command:
      600 Not HTTP PDU
      601 Network Error
      602 No memory
      603 DNS Error
      604 Stack Busy

      • I understand that the error is a network error. Has anyone you know successfully made an HTTPS request using a sim900 module with the firmware mentioned above? I’ve tried different versions and the results are the same. I want to continue trying if it is possible… Reply
  2. Hello, I am trying to update a SIM 868 from version 1418B01SIM868M32 to 1418B01SIM868M32_BT. I am using the simcom series download tool customer but in the window of the target, does not appear SIM868M…si I cannot update it. Do you know any solution? Thanks! Reply
  3. Hi. I have SIMCOM 900 Module (S2-1040S-Z1K0K) (Serial #: MP0615112442952). I am having difficulty to register this modem to a custom-made network (i.e. a BTS). Also, I need my GSM shield to receive a Cell Broadcast message (CB). Anyone has any suggestions about preferred firmware that I can install and upload so my modem can register and receive CM message. Thank you Reply
  4. Hi. I bought SIM900 module. I’m trying to send an email with attachment (jpg, bmp files) through SMTP. I receive email but file is corrupted. After few research, I found out that SIM900 automatically adds CR(carriage return) and LF(line feed) to the file. That causes the corruption of file. How I may fix this problem? Is there any AT command to stop this? Please help. Reply

            After AT+SMTPFT command I send binary data to SIM900. I keep sending 1000 bytes, at the end of file I send remaining bytes.
            16)"AT+SMTPFT=0\r" // no more data, finish.
            I did everything according to the SIM900 Email manual. I also updated firmware to latest one. I don’t know why SIM900 automatically adds bytes (0x0D and 0x0A) to attachment.
          • Sir, when I try to post my code site refreshes, and my comment disappears. I don’t know why. I took my at commands from SIM900_Email_AT Command Manual_V1.04.pdf.

          • Sir, I can finally see the list of my AT commands. Please, can you see any mistake in commands? If you see, please tell me. Thank you.
          • What tool are you using for sending the file in binary format to sim900? Seems to be an issue in that!
          • I’m using terminal software. They are RealTerm and Advanced Serial Port Terminal. I also pay attention to send data in binary mode.

  11. Hello Dost, I’d like to ask you an advice on a SIM800C module. The CIPGSMLOC command gives me a well defined position (even too defined since it’s stable at the 6th decimal number), almost 1000Km far away from where I’m transmitting. In the examples I found over the net I see always position around Paris, like the one I get (+CIPGSMLOC: 0,2.333626,48.802647,2016/07/29,10:52:14). The version revision is 1418B02SIM800C32_BT_EAT_115200. Even more, I’m getting almost the same position with a Sim928A (CIPGSMLOC: 0,2.326602,48.803823,2016/07/29,10:13:12 , firmware revision 1137B01SIM928A64_ST_ENHANCE). Need FW update? Thank you Reply
  12. I have used SIM 900A GSM Module , I connect GSM module with my pc and verify all l AT command working fine check on PC Hyperteminal. Now I have insert Vodafone sim card in SIM900 device. I send ATD commad to SIM900 module and it call to relative netowork. after 60 second some response like “NO ANSWER” or “NO CARRIER” or “BUSY” get on Hypertemianl. can i change that response using AT command? if yes thensuggest us. I need below response for my application in any network GSM Modem dial call to user then 1) if User Pick call then respnse should be “CONNECT” 2) if User disconnect call then response should be “BUSY” 3) if User not pick call then response should be “NO ANSWER” 4) if user mobile phone in switchoff mode or airplan mode then response should be “NO CARRIER” Reply
    • If you need to know if the user picked the call You should set AT+MORING=1 This will let you know if the other side is ringing or call is answered. If the user Hangs the call you get BUSY by default. may be your provider is not sending the busy code. Try with another simcard. Reply
  13. When SIM900 GSM module dial call to user then if User Disconnect call or Not Pick call or Switchoff mode then SIM 900 display “NO ANSWER” response. SIM 900 Module not give response accroding to condition. so my application not get exact idea user pick call or disconenct call or switchoff mode. Note : Right now i have insert Vodafone SIM card into SIM900 GSM Module and USER mobile Service provider is Reliance and Telenor. Reply
  14. Hello Dost I have flashed my sim900 shield with rev.1137B08SIM900M64_ST_DTMF_JD_MMS DTMF tones are working now but I cannot pass the parameters to set the tone duration. Setting the AT+VTD command has no effect, tone duration is always the same, When I pass the duration parameter to AT+VTS I get error back. In sim900 manual 1.1 there is a parameter for duration AT+VTS=? +VTS: (0-9,*,#,A,B,C,D),,(1-255) OK when I try AT+VTS=”1″ I hear the tone at the remote. when I try AT+VTS=1″,100 AT+VTS=”1″,,100 I get ERROR Having the same problem with AT+CLDTMF command, duration cannot be set. I need to build up a contact-ID protocol time line but without setting the tone duration it is impossible. A I using the correct firmware? Any help is appreciated. Reply
  15. Hi, I have flashed several S2-1040V units (sim 900A) but got a shipment of 3 new ones, didnt look so closly so flashed them all 3 as usual… But now they wount boot. They where S2-1040W-Z1K10 (I think its the W that is the diffrence). Anyone have a working firmwire for them? I have tried to flash everything from this site…. Nothing works. The board just sits and rebots itself every second. (same wire with a 1040V works). /KG Reply

          • 1137B03SIM900A32_ST is for Sim900A with 32MB of Flash 1137B03SIM900A64_ST_ENHANCE is for SIM900A with 64MB of Flash
          • The problem here is you have a 32M version of Sim900A for which the new firmwares are not available.
  28. I have a SIM800L that will not provide any response to AT commands. I know the SIM800L is getting the commands via viewing signals on an oscilloscope on the unit’s RX pin (also the unit will shut down when sending a “AT+CPOWD=1” command. On the TX pin, nothing is ever transmitted back. Is there something wrong with this chip or has the software become corrupted? Reply
        • I downloaded the SimCom SIM800H EAT flash tool (since I didn’t see a flash tool for the Sim800L)… I unzipped the files and ran the “SIMCOM_SIM800H_EAT_flash_Tool.exe. I changed the comm port to the appropriate comm and then loaded the .CFG file associated with the SIM800L (1308B09SIM800L15.cfg)… the program than showed four files “ARM_BL”, “ARM_EXT_BL”, “PRIMARY_MAUI”, “VIVA”. Not having any instruction, I checked them all and clicked “Download”. The flash tool does nothing… just sits there at 0% (no files loaded to my SIM). Do you have any ideas as to what I’m doing wrong?… again, are you aware of any instructions on how to use this tool? Any help would be greatly appreciated. 🙂 Reply

          • The application notes are not much detailed. They have just grouped together the commands in any random order and compiled them into application notes. So I am unable to take any help from them.
  35. Hi TEEBLOG. I am using a SIM800L and it fails to register to the Vodafone UK network when using the AT+COPS=1,0,”vodafone” command. Is it possible the firmware version Rev: 1308B08SIM800L16 is locked to networks other than UK? Also if I try to reflash the SIM800L can I use the 1308B09SIM800L16 firmware? and do I use the SIM900 Flasj loader to do so? Reply
  36. Hello, Thanks for your page! I have got a SIM900a module (ATK Sim900a V15). I am living in Europe so I want to change firmware using sim900 customer flash loader 1.01 or 1.9. The connection with arduino Uno is good: this is the answer for “AT+GSV?” SIMCOM_Ltd SIMCOM_SIM900A Revision:1137B13SIM900A64 My problem is that when i try to connect with customer flash loader, the protocol is looked at the initialisation. I try to power only ( no pwrkey so no blink led). Bauds are fixed to 19200 in the arduino software and on the Sim application…I dont understand please help me. Reply
      • Hello, Thank for your interrest. Thé board is here http://store.roboticsbd.com/home/144-atk-sim900a-gsm-gprs-module-bangladesh.html Know, i Wonder if thé chipset of usb CH340 Could be thé problem. I look with native port of an arduino due, it is thé same ! But i see synchronisation bits of the application, maybe my system is too slow ? I am buying à ft232 TTL convertisor so it is possible to have an auto baudrate. Parraps thé arduino program will be better if pin Rx Serialsoftware will exactly correspond with pin Rx usb usine minimum of lines and not using Whyle(Myserial.avaible ()){serial.print(Serial. Read ());} ? What do you think, want and see ft232 ? Or have you got an idea with arduino s? Reply
      • Hello, evrithing is OK. So arduino serial usb chips CH340 is to bad to communicate with SIM900. If connection is OK with arduino but, If nothings append when you are trying to connect and upload firmware, with customer flash loader (using the Arduino as converter) (all versions flash loader) Buy an FT232 serial converter, instead of arduino, and evrithing is OK. Thank! Reply
