Prepaid data is pretty pricey. Thankfully, most of Jerusalem has free WiFi (Ben Yehuda, even parts of the old city).
I went to visit for a week last year, and found myself able to get and respond to email over WiFi (just make sure to keep GSM data off) in most public places, and the rest of the time people could call me (or I could SMS someone to call me back- sms is cheap per message as well).

But enough about *HOW* to use it there, the OP's question was if it will work. Yes, it will. Nothing further is required.

Please keep up the information here. I hope at some point we will get a sticky on International issues as the different countries are spread all around this site. What I noticed about the Sprint system was that they must have contracts with all the GSM carriers since in France it used multiple carriers all with the better signals, so I always had a good connection. At least we can search on the various carriers and countries.
