Thunderbolt not connecting 3G or 4G

I tried the modem tweak last night because when our family was out my wife and kids all had data and I did not. I've had periods of no data (30 seconds to 1 minute) and it's been really frustrating. Yesterday was so bad I was sure VZW had intermittent outages.

Probably placebo effect but my TB seems to be holding data better at my office (notorious for bad VZW data signal).

Placebo effect confirmed.

I've now tried the battery/SD/SIM pull.
 
Anyone fix this yet? Every time I need data on my phone, it doesn't work. I have to flip airplane mode or reboot the phone. The phone is practically useless.
