I have recently taken a tata photon plus connection. First day, my experience was terrible; very low speed; and my skype spewed reds on me.I would want to know few technical details:1. What are the specifications of Huwaei EC152 device; What is its supported speed limits.2. The device shows "CDMA1x HSIA USB Stick" what does that mean? is it CDMA1x which can support only 144kbps throughput, or is it HSIA? if so what does that mean, is it equal to EVDO ? or EVDO and HSIA interchangeable names? As per my knowledge it should be at least EVDO to reach 3.1 Mbps as specified by the photon plus. But if the device is CDMA1x it can't give 3.1 Mbps. Then if it is HSIA i am not sure what it is. Please throw some light on these buzz words with respect to photon plus. Also share any useful information that can help improve the speeds.My troubling doubt is that, Did I get wrong device (usb)? did I get cdma1x instead of evdo? (Huawei ec1261).thanks,__ Mallik.
