If I buy a contract free Verizon HTC 8x (I want the wireless charging), is it then possible to put my at&t sim in and use it or do I need some kind of special unlock?

Thanks

No, Verizon is a CDMA carrier and AT&T is a GSM carrier.

Yes you could, but you could not get LTE. The chipset also handles GSM. You'd pop out the SIM and use an AT%T sim. Apparently, Verizon has unlocked this. For example, you can also do this with an iPhone5 from Verizon. You could get fast HSPA+ internet, but not nearly as fast as LTE. If you want to use ATT just get an HTC 8x there and you'd get LTE.

Yes - I have used an AT&T sim card in my Verizon 8X and it works fine, although you will
be limited to 3G (H) speeds and not have AT&T's LTE.

Let me correct my first post. Here are the frequency specs for the Verizon 8X:



I didn't know it was a dual mode CDMA/GSM phone. It looks like it would work, GSM 850/1900 is listed, providing the GSM mode is unlocked and there's no AT&T blocks on the Verizon firmware.

Apparently Verizon had to do this as a result of requirements with some of the spectrum they bought. They lost an FCC ruling on the issue.

So you can use Verizon 8x on at&t? And possibly t-mobile?

It works with T-Mobile just fine. I have a friend with Tmobile and they also have a Windows 8x Phone. Their sim card worked great in my VZW 8x phone. It even said, "Changing to GSM mode". When I put my VZW sim in their TMobile 8x phone, it would not accept it.

Yes, it works on t-mobile, however MMS and internet sharing does not work. I'm assuming its the same for at&t.

Dont you just have to change the APN settings to fix that ?

Internet sharing is a dfferent story, if someone figures that one out on a Verizon 8X, let me know PLEASE :)
