Hi everybody. I'm using the purchase of my iPhone 6 as a reason to switch carriers, from AT&T to T-Mobile. I'm going to be saving like $30 bucks a month, so we'll see how the service is. Anyway, my number was ported over and everything, but do I need to do anything else to cancel my service with AT&T? Or when T-Mobile ported the number over, is that enough? Switching carriers is new to me, so just making sure I cross my t's and dot the i's. Thanks!
