Airtel introduced 509 with daily internet of 1.4 Gb along with free unlimited local national calls and 100 sms per day for 90 days, but big cheating in this plan is they say it’s 1.4 GB per day and they give only 1kb/s to 5kb/s speed which means you have data but you cannot use a big cauliflower in the ears of customers by this acts it’s loosing trustability.
