Planning to switch to Verizon soon… question..

You should go to a real Verizon store (not a certified retailer) and let them port your numbers/phones over.

You probably have a phone or two that will work on both networks.

You'll be on AT&T until you activate your Verizon account. Once you start porting over your numbers you'll lose AT&T service.

Over the years I've ported numbers from AT&T -> Google-Fi -> Verizon -> T-Mobile and eventually back to AT&T.

You'll be fine. Just make sure you have all account information from AT&T including account number, Pin, (port Pin if available.) If you don't know those things, update now, so you don't run into trouble mid-port.

Once you receive your phones and turn them on to set up, then your ATT service will be disconnected. Not until that time that you port over.

I switched from ATT (which I have had for 20 years) to Verizon in the Fall and regret it. I had many friends who raved about Verizon and who didn't lose cell service during the hurricanes we had where I was out of service for over a week or so with ATT so in my frustration I made the switch.

I'm not sure if they just don't know any better, but my overall service with ATT was hands down better than with Verizon. Slow data speeds, dropped calls, etc. Not sure if it is just our area, but I regret the switch.
