I think add on revised to 249+ taxIn 999 plan, you get 1+3 total 4 voice+data SIM and 1 data only SIM, total 5 SIM. You also get 150+30 GB data, shared among all. You can also add additional SIM, over and above the 4+1, but that is charged extra at 199+tax per SIM, with additional 10 GB data per additional SIM. So, if you want, you can have (4+1)+1 SIM at 999+199+tax, with unlimited voice calls and total 150+40 GB data.
