I use Tata Indicom. When it get connected, it says Huawei Modem connected at 324kbps. I have not actually used any software to measure the exact speed. You may be right it could be only 144kbps. But it is 100% better than the 128kbps Incablenet cable connection i earlier had with a dedicated modem. I only use this when i am on the road. At home it is either Tata Indicom VSNL Broadband or Triband MTNL Broadband both with speeds upto 1mbps. It is damned good, when you use the Broadband connection to call a US land phone or mobile which I often do.
