Try calling 1500 tomorrow morning. I am quite sure that both cities have common tariff plans and this plan should be available in Mumbai as well. The offer is for limited period i.e. till 30th November and it could be that Mumbai website is not updated?tech_your_future said:Huh? Maybe in Delhi, not in Mumbai atleast. If they are offering at such a price in Mumbai, I'd gladly dump this crapway.
