I lives in ghaziabad and the signal here are very poor.and most of the time I just end up in frustration.
Whenever I calls to their customer service call centre they gives useless answer. They may say we will work on your problem or their are many users in your area . They never tells a solution .
Like our mobiles have capability to use any sim these dongles should also have such.These companies are looting and making fool of customers.
I recommend if you want frustration in your life use MTS MBLAZE
