Is it permissible to subscribe to a phone company and receive calls only without making calls?
Question

                I have bought a mobile line (paid in advance). The seller gave me the number, and thus I did not have to call the automated service. As result the counter did not start counting. I gave my number to all my friends so that they call me, I do not call anyone and thus I do not have to charge my phone. A brother told me that this is considered cheating. I am cheating the company; because it sells me the number considering that I will pay an amount monthly weather I use my credit or delay using it. I think that, the company did not stipulate any condition and able to make me unable to use my line, like many companies do. I have paid an amount to get the line itself, and as I do not buy credit, I do not call anyone. What is your oppinion of this?.
Praise be to Allah.
    If the company has activated a phone line in return for a set 
    amount – for set-up –and it offers a service allowing you to receive calls 
    without paying, and it does not charge anything except the price of outgoing 
    calls, then there is nothing wrong with what you have done, and you do not 
    have to call other people in order for your action to be permissible, 
    because the company has agreed to that and it has taken its due by charging 
    the set-up fee, and it has taken the cost of the incoming calls to your 
    phone from those who call you. 

    But if the company charges a fee for use of the phone per 
    month in return for activating the line for both incoming and outgoing 
    calls, regardless of whether the line is used for both, then it has the 
    right to be paid these fees, even if the owner of the phone does not make 
    calls and even if he does not receive them, because this fee is in return 
    for a real benefit, and he is the one who is not making use of it. This is 
    like when a car or apartment is rented but the renter does not make use of 
    them until the contract period ends. 

    Your implementation of the answer is up to you in your 
    country, depending on the system of the company that has activated the 
    phone. 

    And Allaah knows best.
