All tablets are unlocked, even my iPad Mini on AT&T works with T-Mobiles LTE.
For those of you who are still confused, wondering, or in denial.... YES the new LTE Nexus 7 does work with at&t LTE. I got mine today and had at&t activate a new sim card for me and it immediately shows LTE on my device.
Does yours show it with a 4G or LTE icon?
Mine is showing it with the H icon

Apparently you have to go to ATT and have them switch your account to LTE
I had the 2012 Nexus 7, pulled the sim out of that and put it in the 2013
After stopping at the ATT store I now see LTE on mine
I was able to put my Nexus 7 on a prepaid AT&T DataConnect Pass. This is how I did it.
I walked into an AT&T store and found an Android tablet with LTE on display. I wrote down the IMEI number from the tablet after clicking on Settings, About Tablet, then Status. After that, I went home and logged onto my PC to the AT&T DataConnect website. (Here is the website.)
I entered my credit card information, the IMEI of the tablet from the AT&T store (NOT from my Nexus 7), and the number from a new AT&T micro SIM card (never activated) for the ICCID. I selected the 250 MB plan for $14.99/month as a test. (The other plans are 3 GB for $30/month and 5 GB for $50/month.) I then inserted the micro SIM card into the Nexus 7. After I turned it on, I was able to get LTE on AT&T's network.
Since it's a prepaid plan, I can cancel it if I don't need it anymore. If you're on your Nexus 7, you can click on Settings, More..., then Manage mobile plan. The Nexus 7 will automatically direct you to AT&T's website, where you can log in with your username and password. After that, you can change or cancel your data plan.
Fun fact: You can use the same SIM card in a Nexus 4 smartphone for data if you change the APN settings to match the ones on the tablet. You obviously can't make calls, though.

Looks like I'll need to cancel my auto-renew and then activate my new LTE SIM with a new line of service with auto renew turned on. My HSPA 3 gig data plan is up Oct 3rd, so looks like I'll be waiting until that date to get LTE on my new N7, as I don't want to activate another line of service.
