An "
unlimited" top up for Orange will give you unlimited voice+test messaging in Israel + 1GB data for NIS 139 (USD 40) . Add NIS 20 and get 4 GB.
In Israeli terms this is still very expensive - I pay NIS 30/month ($8.70) for unlimited national voice + SMS, 3GB data and unlimited voice landlines in 31 countries.
I just fount the site of a new Israeli MVNO called
019mobile offering what appears to be very good conditions - especially for visitors from the USA.
