Israel continues to attract a lot of traveler thanks to its rich cultural and religious traditions. If you are planning a trip to the country, then you should include plans for buying a SIM card. The data rates here are quite affordable so you can enjoy large allocations at a relatively low price.
Before selecting a carrier, check the coverage areas for each. Look at the places you are aiming to visit on the map and see which carriers have a strong presence there. If you are going to stay in Tel Aviv and other urban areas, then any of them will do. If you are venturing farther, then you need to be more discerning.
You can purchase an Israel SIM card online and have it delivered to your preferred address. You may also buy one when you arrive at the airport, though you will pay more for the product. Wait until you get to the city to buy one at regular rates.
