I had my landline number ported to a new Iphone today at the Verizon store. Will my landline service that keeps my internet service sill be effective? I did not cancel my landline phone service or my internet service. I can't receive phone calls on my Iphone at home. I can receive and call out on the Iphone away from my house. Is anybody aware if this is safe? I don't want to risk losing my landline service. I can't even get through to Verizon on the phone to ask this question.
