How to Upgrade to an SE with an ATT Unlimited Plan?

[JackBQuick]

I've got a grandfathered att unlimited plan and I use a lot of data. (6ish gb/mo) I'm out of contract and would love to update my 5 to a SE. What's the best route to go?

I too, have a grandfathered UDP since the iphone 4, and have had every generation of iphone up to current 6s/s plus. I buy my phones outright and put the current SIM card in and that's it. At&t seems to recognize it in their database with no issues. I would imagine you can call AT&T to confirm your phone changes if needed.

I always call and speak to an agent to confirm my UDP and activate whichever phone I've chosen.

ATT isn't try to trick you out of your UDP, in my experience.

Simply buy the phone outright, or do AT&T Next. Those are your two options. Whichever channel you purchase through, just tell the person who's processing your order that you'd like to keep your plan as is. If you choose to do next, it'll just add the installment plan on your bill, and a $15 renewal fee. If you pay full price up front, nothing changes. I recommend visiting a corporate store, or calling the customer care number, as opposed to visiting a national retailer like Best Buy/Walmart/Sams Club etc, or an Authorized Retailer. You can find which stores are which on att's website using the store locator.
