You might have seen Vodafone selling mass SIM cards. 1+1, 1+1+1 etc.
Please don’t get cheated by this. They will ask you to pay 100 and get connection.You will not get connection for sure. They just reject the applications for simple reasons.
Meantime they already collected 100 rs each. Now you dont have an option to refund the money. The agnet will tell, once application is submitted and rejected no refund.Please please go to a proper dealer for SIM card.
