I'm really curious if this is still working for you guys. I've tried it and it doesn't help long term, still occasionally dropping data. My guess would be it's not the setting that may be helping you, it's the power down and SIM card pull which forces the phone to reprovision itself on the network on the next power up.
Anyway, my guess is that the issue has something to do with their LTE authentication system. See the link below for more info:
This Is Why Your Verizon Galaxy Nexus (Or Other 4G LTE VZW Phone) Is Losing Its Data Connection
Well they should hurry and get this fixed because it seems to me they are sending out a lot of sim cards and replacement phones for network issues if this is the case. I'm all for device replacement if that's the problem but people get ticked off when even that doesn't fix the problem and start blaming phone manufacturers when if this article is true its Verizon's networks. The more LTE phones they sell the bigger the problem will get and they will start losing customers. Who cares how fast a network is if you can't use it, kind of like Sprint's unlimited, who cares when its dial up or less speed.
Yuuuuup
