All Israeli kosher plans can only make and receive voice calls.
Text messaging and emails will not work on a kosher plan for both sending and receiving.

If you ordered a Virtual Number with your plan (order here) or want to order one (order here), we offer an option of sending and receiving texts on your Virtual Number that will go to email (for sms 2 email see here or it could be ordered as an add-on when ordering a kosher plan here.)
