Techcraft — To change 3g to 4g

Address:

Chennai, Tamil Nadu

My mobile no is [protected].Two days ago i have changed my plan 3g into 4g.So i boughy one swap card and i sent a message which was in the swap card As soon as i received the message then i sent a confim message to airtel with Reply 1 option .After that i had been waiting for a long time. But i didn't get any confirmation message that the no is deactivated or not and my new 4g plan added or not.I want to know that the reason is my no still getting activate or not.Even if it is in activation process i couldn't move any application in my mobile
