How to remove array element in mongodb?

by

Here is array structure

contact: {
    phone: [
        {
            number: "+1786543589455",
            place: "New Jersey",
            createdAt: ""
        }
        {
            number: "+1986543589455",
            place: "Houston",
            createdAt: ""
        }

    ]
}

Here I only know the mongo id(_id) and phone number(+1786543589455) and I need to remove that whole corresponding array element from document. i.e zero indexed element in phone array is matched with phone number and need to remove the corresponding array element.

contact: {
    phone: [
        {
            number: "+1986543589455",
            place: "Houston",
            createdAt: ""
        }
    ]
}

I tried with following update method

collection.update(
    { _id: id, 'contact.phone': '+1786543589455' },
    { $unset: { 'contact.phone.$.number': '+1786543589455'} }
);

But it removes number: +1786543589455 from inner array object, not zero indexed element in phone array. Tried with pull also without a success.
