I want to get a 2nd mobile number. I am not looking for data / Internet on it. Just to have an active number with minimum balance for either emergency purpose or giving on websites when selling something or like FB which is forcing me to enter number to access marketplace and such.
What is the cheapest prepaid mobile service I can get? I have Vodafone currently, but for new number, I am open to any provider. It has to be cheapest to maintain.
I don’t want to pay every month and if there is a way to just pay like topup and such (don’t want to get those 1 year plans as they too cost thousands).
Edit: I am in Mumbai, so BSNL is not an option.
