$10 per day is a lot of money for phone service in Israel. You should be able to buy a local sim and get a monthly plan for about 30-40 Shekels/month which includes unlimited/practically unlimited calls, texts and data - but not calls to the US.
For example, Golan Telecom has plans at 30-35 which include 100-120GB of data, unlimited local calls and text and 0.82 Shekels/minute calls to US landlines and cells. Golan also has a 99 Shekel/month plan that includes 500 minutes of calls to US landlines and cell phones. This plan also comes with a US number that you can be called on which redirects to your phone in Israel.
Note: these plans are not prepaid - they're post-paid. It's quite easy to set up a post paid plan in Israel and then cancel it when you don't need it anymore.
