No it does not help.  There is zero reason the Key2 non-LE can't work on the network.  In fact it is working in all ways except receiving texts.  Others have commented in crackberry forums and here that if it is provisioned just as the LE, it will work.  Calls, data and sending texts are all great.  The problem is receiving text messages and that is because the network is trying to send them using the incorrect protocol.

"got a key2 le. brought to verizon store. they put in a new SIM. It worked. Then transferred the SIM to the key2 and everything worked (calls, texts, and data)"

So no, it does not help - a competent tech who understands what they are doing would help.  I'm much more loyal to blackberry than VZW at this point.  Especially when I called and confirmed with VZW prior to purchase that the KEY2 would work with the LTE network...of course not the 3G CDMA..but I can live with that.
