Have you solved this? I'm asking because I have the same problem. My suspicion is the GSM operator blocks inbound TCP connections. But a friend of mine is using a PC with an USB GSM modem configured as a SERVER. And it works! Will try to borrow his sim card to do some tests.
Hello, I have developed a modem application using sim900 modules. The problem is that now i am trying to use 4G LTE sim card and i have not accomplished network registration. If i use a GSM/gprs sim card it works. What it could be? Thanks for your attention. Ricardo

sim900 it is a GSM module for 800/900/1800/1900 MHz bands, so it will not work on other frequencies. GSM its a half-duplex TDMA system, with RX and TX on different frequencies AND times. To boost both signals designing the amplifiers to meets all the GSM network regulations, is a challenge. Here you can

Yes for using gprs you should have balance in your sim card number or you need to activate any gprs data sachems with your sim network service provider and its is a GSM device like a cell phones and your sim service provider paying money to government and you must pay it to your service provider so you need (...)
It will automatically register to the network once you connect the sim card and power it up You can check using the following AT command AT+CREG? // to check network reg. AT+COPS? // to see which operator of sim card you are using like for example - Vodafone

Hello Friends, I am going to buy a sim 928A module/chip. So i want the reviews for this module. Anybody who have it please share some tips for me. Expecting to know - 1) What type of GPS data it send through GPS_UART 2) Type of antenna that requires.. etc. Thanks in Advance...!!
It's a good module , you could use sim908 , it also includes a GPS almost at the same price. The sim modules has a lot of info.
Hello all, Can anyone suggest right product of GPS/gprs/GSM combo module?? similar to simCOM's sim 908. Also any module is available to switch over one network to another network in case of network failure?? This would be highly useful for GPS/gprs based Vehicle Tracking Systems?? Pl suggest.
Have you checked the Antenna? Is the modem working with another sim from another provider?

The sim300 is no longer manufactured by simCOM, but instead the upgrade is now the sim900. The AT commands remain the same, so these commands can stay the same Their is a paperback book on how to interface a Microchip PIC to the sim300 written a couple of years ago. The book was called "Microcontroller Based (...)
