I guess I will have to sort it out once I move there. As far as Golan service which phones from the US will work? Verizon etc?(Is it worth getting a phone there?)
Golan should work with everyone phone besides Blackberry (AFAIK).
Bringing a phone from America is probably better, as most technology hardware costs less there. You just need to make sure the phone you have has a slot for a SIM card (not all phones marketed do), and that Verizon can help you unlock it for international use. I am currently using an Android phone I got through Verizon- before I left America, I just called them up and they told me how to unlock it.
The larger cell phone companies (Cellcom, Orange, Pelephone) often have deals that you can buy a phone through them together with service, and then you end up not having to pay for the phone (they spread out the payments over 36 months, and give you a refund each month). This is good and bad because even though you may end up paying nothing for the phone, it ties you to the company, and if you want to leave you have to pay for the phone (and the price they make up for the phone is usually at least 2x what you can buy it for in America). I personally have had bad experiences with this, and from now on have decided to just buy phones for us from the US instead of through the Israeli companies.
