In my previous post I have mentioned how to unlock Vodafone K3565 USB modems which are manufactured by Huawei.Many of  us out here are having the K3570z model and wants to unlock it so that it can be easily used with other networks.Thanks to Ujjal Kar who have provided unlocking utilities to unlock the latest USB modem from Vodafone manufactured by ZTE and sharing with us.

Update:Vodafone is now providing a connection manager which allows you to use any SIM card.You can get it here

Before you start you need to get the unlocking and connection manager utility.Get these files from here ZTE Drivers, ZTE Connection manager

First of all install ZTE drivers.In case you have installed Vodafone ZTE connection manager uninstall it first perform a reboot and then install ZTE drivers.Once done install ZTE connection manager (ZTE Join Air) and open the connection manager wait for some time atleast 1 minute, software will unlock your modem.Almost done its time to configure the connection manager with your SIM card inserted.

Connection

Like most of the data cards a Green light indicates that you are on 2G network and Blue or skyblue means a 3G connection.Red light indicates no connection.
