    Currently, I am still clinging on to my beloved HTC 8X for Verizon. I want a new Windows Phone, though I don't want to enter into a new 2-year contract in case the Talkman/Walkman make it onto Verizon. If they don't perhaps the Surface Phone will. Because of this, I was looking for other CHEAP Windows Phones as I am currently on a budget. I found that Microsoft was doing a promotion for a $69 Lumia 640, locked to AT&T. It is my understanding that AT&T makes it relatively easy to unlock a phone. I figured I could unlock the locked phone and try to slip my Verizon SIM in. Will this work? If it does, will LTE work? Should I give up hope on Verizon's support of Windows? I can't change carriers because I'm still a part of my family's plan and Verizon NEXT is just too damn expensive. Will this work or should I just keep waiting? Thanks!

    It's not possible to use any non-explicitly Verizon phone on Verizon.

    I'd get onboard with a 928 or 735 if you want to spend some more.

    The LG Lancet is worth a look.

    This isn't totally accurate, but it is true for Windows Phones. Apple, Google, and soon Motorola all have factory unlocked phones that work on Verizon.

    OP, no the 640 will not work on Verizon, even if you get it unlocked. Verizon uses CDMA technology, but the 640 has GSM only.

    I'm not sure which iPhones are unlocked and work on Verizon. So far only the Nexus 6 is unlocked and works on Verizon. Why doesn't the Nexus 5 work on Verizon? - Android Forums at AndroidCentral.com

    That is correct.

    The factory unlocked iPhone 6/6+ work on Verizon. Even the T-Mobile and AT&T models work fully on Verizon if they're SIM unlocked. Here's a discussion about it on Howard Forums:

    Theoretical: Use an unlocked GSM iPhone 6 (Plus) on Verizon?

    Here's another article from an Apple forums:

    not only is the iPhone 6 unlocked, but the t-mobile phones work on verizon!

    The upcoming Moto X Style Pure Edition is also supposedly going to work on Verizon. The AT&T Nexus 6 also works once it is SIM unlocked.

    The LTE bands are supported though. Couldn't you, in theory, rely on VoLTE and not worry about the CDMA bands? I know very little on this topic so correct me if I'm wrong.

    I forgot about the Nexus 6 and such!

    But ultimately, you aren't going to get that 640 onto Verizon. You'll have to get a VZW phone as far as Windows Phones are concerned. Even in most other cases it is the same.

    Verizon's network is on a whitelist too IIRC, and the 640 isn't on that.

    No, Verizon is CDMA. I'm no expert, but this article explains the difference in layman's terms. The "W" matters!
