Hello all, I would like to switch my wife and I from AT&T to Verizon, and port our existing phone numbers over to new Verizon phones. I will most likely (if there are no deal breaking issues that come out of the reviews!) order 2 iPhone X’s from Verizon’s website. I know that at the time of ordering on their site, it prompts you to enter the number(s) that you want to port over. My question is, once I enter our numbers to be ported, and initiate the order, at what point does the transfer process begin? If after placing the order, it takes a few weeks (or longer) for the phones to get to us, will our existing AT&T service still work? I want to ensure that our AT&T service is unaffected until we activate the new Verizon phones. Thanks!
