Yes, its really a subsidized subscription that allows people that can't use the trending tweaks on their devices.
This data plan is just okay for your internet activities except for heavy downloading and video streaming because those two mentioned online activities can flush the 3gb in one hour.
DEVICES THAT SUPPORTS THIS AIRTEL 3GB DATA PLAN ARE:
==> All Android devices
==> All iOS devices
==> All windows phone
==> All Java phones with internet support
==> Symbian phones with internet support
==> PC via internet modem
You don't need any vpn app or any configurations to enjoy this offer, to opt-in or subscribe for the Airtel 3GB for N1000 internet data package, just recharge N1000 and dial *431#.
Also to check your data balance, simply dial *140#. I hope this data plan is fair for those that can't just tweak or flex free browsing tweaks.
