JIO pay saying my data is exhausted means your JPO isnt activated coz JPO is unlimited (4GB then 128kbps FUP) and base FRC gives 2GB data for free then JPO Activates , so you exausted that 2GB .. dnt wry JPO will be activated within 24hrs and you will see Unlimited and Welcome / JPO Offer in a Big Banner in MyJIO..
BTW Welcome Offer night is not unlimited yesterday downloaded 4.8GB (2:30am - 3:15am) then today when I started browsing speed is capped to 128kbps.
