You said that your Huawei E1750 modem works great. What kind of OS configuration do you have? does is work properly with Windows XP? Could you do this test for me? I'm planning on buying the same modem.
Any help would be welcome. Thanks.
I was using the Huawei E1750 modem on Windows XP.
I had a few issues trying to find compatible drivers but in the end I was able to send and receive text messages fine.
