I have seen so much of their creativity advertisements  for the best network and the internet speed and thought they have best plans  among other now  . So I recharged on my number 9556112#86 for three months validity  with unlimited talktime and per day 1.25 GB  . After my recharge , I regret thant being a loyal customer for last 5 years  with this network  .
This is not best network than other mean only jio  . Without jio all are pretending  . It has not best internet speed  but jio gives up 2mb/sec to 37mb/sec internet speed that  I am using   .  In this 4G network especially doesn't  catch work  . In this network 3G speed is better than 4G in tortoise walking speed   .
I have used other sim in my mobile sim slot  which works so perfectly  . So I am saying Please never say it  "Best"  . We are the customer which have right and permission and decide to who is best   .
There are lot of tricks done by telecom companies to fool customers and make money  . Fraud advertisements  , call drops  , crawling, FLAUNCTUATING internet speeds  , deliberately long IVRS  hold ups are just trip of iceberg and airtel ace at these   . So yes  it is the wrost network
