Moving your phone number to your new provider will automatically cancel your service with Now , i would strongly advise that if you want a landline/phone service with your new provider oand/or your new provider has a phone service that you sue this process to cancel Now.
Your new provider will trigger what is called a number port, and you will/should get a message from Now saying something like sorry to see you go that process is automatic and you should not need to contact your losing ( old - ie Now) provider
