@LTE4G Good point, reg the possibility of call being restricted from JIO's end as well, to minimize IUC payments...
Now I have seen that only 100 calls / minutes free per day limit applicable for prepaid users in JIO. NOT sure, if its a welcome offer thingy or applicable for all, especially in Rs149 plan. I am sure nobody will care about that in JWO, as calls are hardly connecting. For Rs149 per 28 days, if they apply the same limit (100 mins per day) that brings to 2800 minutes for Rs149 and with current IUC of 14p / min it comes to around Rs392. That Rs243 loss can be easily adjusted by IUC from incoming calls [14p/min income by IUC] and Jio2Jio calls (no need to pay IUC for the calls), unused FREE calls per day, overage charges @ 2p/sec in home and Rs0.45 / Rs0.80 / Rs1.15 during roaming.
Simply put, FREE calls is NOT a big deal / loss for JIO, imho...
