This is the first network I choose from the purchase of my first phone. It’s been 6 years I am using this network and haven’t experienced any issue till date. Their customer service is bit impressive not just like other networks and very cooperative. Clarity in voice with no cuts and breaks. Even you can have full signals at village areas and while travelling in train or bus there will be bit network issue.
Coming to the tarrif plans they do have expense plans but the quality they provide would justify and their 4G network speed was awesome but due to high cost medium class people can’t afford this network.
If airtel reduces it’s tariff plans, It is the best network than all.
