Connectivity is the big time issue with Airtel. You upgrade to any-plan xyz whatever but frequent disconnection will not be solved. Even the Airtel’s on-field technician are tired with the complains everyday for same problem. I will never recommend Airtel Broadband to anyone.
For Business they take 24 hrs time to resolve the issue. This is worst thing for any business, you cannot delay your work daily just bcz. of bad broadband connection.
