Airtel 4 G network is expensive network if we talked about 1 year before but now due to the competition with the jio it also provides 399 rupees plan for unlimited calling where you can get a 1 GB data for one day and this 399 rupees plan Validate for 30 days. If you are a user of BSNL Aircel or Vodafone and your coming into Airtel network then you can feel the difference Internet speed in Airtel 4 G. But in Airtel network plans it always some catch, Airtel mention that sometimes it’s unlimited but it’s a limited at midnight or something like that so you should really take care of that thing if you are coming to Airtel network.
I have a used Airtel network more than one year and is always reliable and provide good speed of Internet.
Conclusion is that due to the jio Internet plans Airtel also provides cheap plans. As if now we can see some problems in jio network because million of subscribers in a jio network so if you feel some problem with the jio Internet you can switch to Airtel four g.
