Previously Vodafone launched K4505, K3565 and K3570 USB modem. Now latest dongle from Vodafone is Vodafone K3770-Z ZTE version with 7.2 Mbps downloading speed and high speed uploading also. To make review for my visitors I just purchased this modem from my local Vodafone store. Look wise it is same like K3570-Z slim and easy to carry. Modem have no option to insert memory card. One more thing I got from DC-Unlocker that it is designed with new ICERA Chipset not with Qualcomm. I insert TATA Docomo SIM card and modem easily detected it without any unlocking process. But Vodafone default software not permission to connect any other SIM card than Vodafone. Currently I have no direct solution to access this modem using other SIM card but we can use this modem without any software using Windows Dial-up feature.
