I do not agree with this. Every dth has pros and cons, just bcoz of mandatory condition of min 100 Rs recharge for resumption of services airtel cannot b considered bad. Also i change update packs/bouquet / channels regularly thru their app and do not face any issue. Picture / Audio Quality of airtel is very superior than Tata Sky, they offer max SD and HD chs.... Few r missing but same is case in Tata Sky too, airtel too offered much better special discounted bouquet / offers in pre NTO era and continued so during NTO period too which Tata Sky did not and recently resumed, Also Signals of airtel seem to b quite strong and do not get much affected by rains... In Tata Sky too same is the case, Customer Care / Issue Resolution Time in airtel is also quite good and on par with Tata Sky.... Though i have heard that Tata Sky has deteriorated a little in this criteria in last few years, Logo issue in airtel was not so major but still it is being resolved now...... Airtel Xstream software/hardware, functionality, features, user friendliness is better than Tata Sky Binge STB. There r many other things i can list which indicate airtel is excellent DTH operator.
If grandmother can face issue in selecting channels it will not b bcoz of lagginess or bugs in airtel app but bcoz she may not know process to use app or its features.... This goes for airtel or tata sky likewise. One thing i am sure about it is that elders do face initial issues in typing 4 digit lcn which tata sky has but later become accustomed to it, airtel still does not have this feature but will introduce it sooner than later. What i wish to convey is learning new things takes time and it cannot b attributed to operator doing something wrong
