Wow... You clearly dont know how SIM cards work then...

SIM cards NATIVELY can be locked to DEVICE, NETWORK or COUNTRY. In this case, the LTE card would be locked to DEVICE and NETWORK.

If you want a new device, you get a new card. That new device will likely have to be authorized via IMEI and if the IMEI doesnt match up before the card is issued, then said card isnt issued. Since the card is good ONLY for the IMEI, once the card is issued, if the subscriber decided to use it in a non-Verizon device, the SIM remains locked.

They do this on GSM - so its no different on LTE. Nice try though.

^^ what he said.
Also wasn't it already reported that Verizon's LTE devices would be locked down harder than Fort Knox?

nah, not really, I've used my GSM SIM card in probably four or five devices already, some of them I've bought from abroad and unlocked, some from other GSM carriers that were unlocked, and some have belonged to my carrier, and were locked.

My GSM card is not locked to any specific device, I mean, but the devices were locked to their networks before unlocking them. Whereas with LTE it seems that the Verizon can recognize when I put it in, say, unlocked AT&T LTE phone (if that's how it will work), and refuse to service me based on the fact that it's not their phone... i'm sure that if there's a SIM card, there will be a way (official or not) to make it work in any device of your choosing. we'll say how they play it out

they have to do this. if they do not the phone will not work, because Verizon is CDMA and they are using a GSM based LTE for the 4G network. if the phone (for example) is a LTE based AT&T(or any LTE phone) phone and you use a Verizon SIM card in it it cannot covert GSM to work with the phone. the phones that Verizon are going to be using are CDMA based but with the SIM will receive the LTE network, the SIM cards are going to only receive a GSM band so the phone will work while not connected to a LTE tower. so to make it easy, if you get a unlocked LTE phone it will only work while on LTE, since it will cost too much and no wireless carrier has data on every tower you will only be able to use a unlocked phone on LTE, so most of the time the phone would not work.

What do you mean? LTE phones won't be GSM or CDMA based. Those old technologies are yesterday's news. Even if a way hasn't bee found yet, some hacker will find a way to unlock LTE phones and use other carriers' SIM cards in them, just as you can with GSM phones now.
