One thing I thought I'd mention for frequent international travelers.
So far, every foreign SIM I've installed has automatically enabled "Hotspot" mode. I'm in Israel right now and have a Pelephone unlimited plan (costs me about $30 US/month) with unlimited data and unlimited minutes. Once the SIM was in the phone, I went to the Hotspot option, turned it on and voila. Portable unlimited 3G data. You don't have to have a Hotspot plan enabled via Verizon for this to work. The foreign SIM just needs to allow for it (Pelephone and O2 both do it appears, no extra charge).
Not sure if this is working as intended or not but can confirm that it does work and you aren't racking up international data usage.
