I'll have to look closely at Verizon's Unlimited Together - World plan plus an Israeli SIM. I'm currently only in voice contact with business associates and hotels, all of which have cheap ways to call me - but I'd like to be economically accessible to some friends and relatives who may not be set up for cheap calls and texts to US numbers. Not to mention guides and local businesses.

Can you recommend a prepaid voice & data SIM I can get in the States before I go?
