Israel is a popular destination in the Middle East. As the historical center of major faiths, it benefits from the pilgrimage of millions to the Holy Land. It is also a hub of business and technology in the region. Several historical sites draw people of every persuasion.
Anyone who has ever been there will know that prices are quite high. Fortunately, mobile internet is an exception. It would be best for traveler to get a local Israel SIM rather than depending on roaming services. It would be cheaper and more reliable.
You can purchase a SIM card even before you leave by going online. You can also find lots of them being sold at the airport, although the prices are much higher here than in the city. Wait if you can until you arrive at your hotel to buy a SIM card.
