Retaining Israeli Cellphone Number Without Monthly Fee

I had a cellphone plan for years which did not charge a monthly fee. I only paid when I made phone calls. I recently lost this plan. I am looking for a way to keep my number and to be able to receive text messages without paying a monthly fee. The cheapest plan I've found would be around 17 shekels a month from Golan, but I am looking for 0 shekels a month.

Any advice?

Thanks.
