Mary I know what you have explained is OCD. The only solution coming to my mind is - just throw away all your phones, or just hide them somewhere if you can't do that ask someone to do it for you so you don't know where are they. Okay second step is to calm yourself, think what if mobile phones doesn't exist at all or if by chance they are stopped being used anymore then also you'd be living without them.

Try this and give the feedback.
