[HTC U11  Questions & Answers] aer0zer0:
So i was on the chat with HTC about how to activate one of these devices on Verizon with no pre-activated sim. It may be regurgitation already, but here goes (directly from HTC representative)

Carlos M.: Yes, and you will need a new SIM card (4G LTE) and for Verizon to remove the CDMA-less provisioning, as well as add the VoLTE service, adding the device to the BYOD and activating it after all this is completed from the carrier!

You: So, my current phone is a VZW 10, with VoLTE and HD calling already enabled

You: i should just be able to swap it in and go?

Carlos M.: So, you will need to change the SIM to a new 4G LTE just to be completely sure, and request the removal of the CDMA-less provisioning

You: so i would need a new, no matter what?

You: sim

Carlos M.: But of all the cases I have seen the main reason the device loses the signal is that the SIM was not changed and the service not removed.

Carlos M.: Yes, that is the main advice.

You: How do i tell the verizon store how to remove the CDMA-less provisioning. I have a new sim in my hand

You: its the bulk4ff-nfc-d sim

Carlos M.: Exactly like that, John! You go to the store and tell them I need to check that the VoLTE is provisioned in my line, and I need you guys to remove the CDMA-less provisioning service from it, please!

You: ok

You: is there an uh oh, or returne policy if they cant get it to work

You: if i could switch to a gsm carrier where i live, this would be a non issue

Carlos M.: OK, the standard buyer's remorse policy is 30 calendar days after the device is shipped to you. This phone has no Uh Oh protection plan

You: i live in the boonies, and vzw is the only thing that works where i live in upstate ny

Carlos M.: Oh, I see, John! I'm sure you can have your device working perfectly normal with this steps!

You: if this had been like the VZW 10, i would have owned 2 already.

You: im only thinking about it because of the promo, its a great deal for a phone of that calibre

Carlos M.: It sure is a great promotion, John! I hope you take advantage of it!

You: i hope so too, thank you very much

You: one last question

You: i realize they are all the same phone, except for sprint. (unlocked)

You: if i was to select teh verizon specific one

You: does that mean that phone is in verizons imei/esn pool already

You: and it should be easier to activate as opposed to by the unlocked version, even though they are the same phone?

Carlos M.: That is a carrier version, but it is unlocked as well so you have to check with them the device is added to the BYOD list

You: so the imei/esn pool doesnt matter?

Carlos M.: It doesn't. The recommendation is that you check with them that the device is added to that list

You: how do i get them to add it to the list

Carlos M.: Just like that. You can request the device is added to the BYOD list in a store when you have it in your hands

You: ok

You: that is all i guess

Carlos M.: You're welcome, John!

maybe this will help [MENTION=5027435]christiebunny[/MENTION]

Looks like the high spot are as follows (New 4G LTE Sim bulk4ff-nfc-d, they have to add HD Calling for you, They have to remove CDMA-Less Provisioning for you, and You have to add the IMEI to BYOD Pool Prior to all of this)
