You could check the availability of these plan in your Rcom sim by dialing *129# then going to 10GB DHAMAKA OFFER. I have 3 sims and all of them are giving me these 349Rs. 10GB plan. I checked the speed and the data after recharge, They are providing these under promo balance that means data couldn't be carried forward after 28days. Breakup of data balance 3.5GB Core data which can be carried forward + 7.5 GB Promo balance which can't be carried forward. Also their are some sim specific plans like 10GB 2G FOR 56 Rs. , 1GB 3G for 73Rs. and 2GB 3G for 128Rs. which are not available for all but for spwcific devices which you could check via USS *129# then go to Paisa Vasool Offer. ** All above plans have 28 days validity Looks like JIO EFFECT to me.
