I got a huawei E160 locked to SafariCom Kenya. Seems to work with Frontline for Sending, but I can't receive. Your docs recommend E-series Huawei modems (http://www.frontlinesms.com/resources/requirements/) -- has anyone else found difficulty receiving SMS?
Oops- looks like I got it working. Took over 5 minutes to cycle back the SMS test recv.
Another note: When setting up Frontline SMS on Windows 7, you need to first load the SafariCom, Orange, Yu, Airtel, or MTN modem software so you can enter your PIN for the SIM card and confirm that the hardware works with your network. Then Second, close that software, disconnect from the Internet, and load Frontline SMS software. I have orange and safaricom on this PC and had to fight orange repeatedly from trying to take over control of the modem. If another competing software is in memory, FLSMS probably won't work.
(dunno if the documentation is very clear on this point)
Well done on getting round this. One of the bigger challenges for us are the number of external factors that can stop FrontlineSMS working. The problem you faced, with another program running and taking the port/messages, is covered in the "Troubleshooting" section of the "Help" files.
Best of luck out there!
