How to choose GSM Device or Mobile phone ? |
| |
| • |
We recommend GSM Modem which is better in performance, stableness, and compatibility compared with mobile phones.It should able to work continuously without charging. its signal quality also outperforms mobile phone. Commonly used GSM Modem includes WAVECOM, SIEMENS, ERICSSON, MOTOROLA etc, we recommend using WAVECOM WMOD2. |
| • |
Mobile phone is also a good choice for the software that doesn't have a large number of messages to be sent. With so many brands of mobile phones exist in market, an outdated model with good condition are preferred. Because they are cheap, and the stability have been tested by the market. Features such as chord ring, color picture and camera contribute nothing to the system, on the contrary, it decreases the standby time and increases the charging times. Among commonly used brands of mobile phones on the market, Nokia and Sony are most suitable to this work, and most importantly, Sony shows best support and compatibility for AT command set of GSM device standard, we strongly recommend using these brands. |

How to Set Connection Mode ? |
| |
| • |
SMS Integrator supports GSM device with different interfaces, including serial port, USB, Bluetooth, Infrared. For USB interface, usually it is simulated to a virtual serial port by installing the device driver. And then you can choose the virtual serial port. If you are using GSM device with Bluetooth interface, be sure to install a Bluetooth adapter onto your PC, the adapter driver will then simulate Bluetooth interface to a virtual serial port. And then you can choose the virtual serial port. For GSM device using IR connection, there are 2 communication modes. One is connecting through IR protocol by choosing Infrared. The other is simulating IR to a virtual serial port, and you should choose virtual serial port, rather than Infrared. |

Message delivery failures. |
| |
| • |
Make sure that your SIM card provides SMS service, and your balance is enough to send a SMS message. |
| • |
Check the SMSC number to be correctly configured. If not, you can use the File -> setting menu to set a valid SMSC number. However, NOKIA phones may have troubles to get and set a SMSC Number. Please check the number manually through your phone. |
| • |
The message delivery failure is sometimes due to a busy network. |
| • |
The software uses the PDU mode to send messages. If your hardware does not support this mode, please contact us. |
|
| |
|
Messages cannot be received by recipients. |
| |
| • |
"Successfully sending messages" only means that messages are submitted to the GSM network, and it takes certain period for the network to forward them to the receiving mobile phone. It will take longer during a network busy time. |
| • |
When the receiver mobile phone is temporally not connected to the network or simply powered off, the SMS center will discard the time-out messages, so that the receiver's mobile phone is not able to receive messages. Generally 1440 minutes (more than one day) is the value. |

You can send a message to yourself for testing purpose. |
