Bring you own GSM phone from abroad. You will be able to join a prepaid service in Cellcom and Orange networks. Regardless of the network, a minute costs less than 1 NIS.

At the first floor of the Kanyon you will find representatives of all above mentioned companies. If you increase your ballance with a card bought in a kiosk/shop, some companies charge extra money for "service" (e.g. you pay 60 NIS for a Talkman card, but your balance will be increased by 53 NIS).

It is also possible to add balance to your SIM card (most carriers) at the post office.
