In our today life vodafone get it name and fame but I dont think it was happen I am using it from 9 to 10 years firstly her plan was good and affordable but now they are increasig her price day to day it can now become unaffordable to buy her calling or 3g plan due to this reason I uses airtel plan which provides me unlimited calling and unlimited 3g+ data for a month and her tower service was also good but the vodafone only do fake promises with other they never apply her plans on market in a fear that they face loss and her tower service is worst and take a postpaid plan with vodafone always use prepaid if you have prepaid then be prepared because they charge value of so many things and impose tax of so many things due to all these reasons I am thinking to change my sim cARD from vodafone to airtel.
