Hello im going to share my experience with airtel broadband.
Ive been using Airtel broadband from years now and I have subscribed to unlimited data pack. And let me warn you to never use this brand network beacuse has gone bad to worst these days beacuse the speed never goes higher than 50kb/s . The broadband kept on restart on its on and half of the time it doesnt work . I have always complained about this problem to cutomer care about adsl not working properly but they say that everything is working fine from here and ask me to wait and check my modem.
And the person they send to repair are so unprofessional and doesn't know his work. He keeps cutting wire again and again and join them . The connection is weak and slow. I would not recommend this to anyone.
