These phones are hard wired to be a talk only phone that is incapable of supporting texting or internet, Kosher Phone is the only phone in America which carries the stamp of approval from a major kashrus agency, the Baltimore based Star-K, under the guidance of Rabbi Moshe Heinemann.

The phone, a Samsung SGH A157, is a black flip phone which readily displays the Star-K logo on its screen, making it easily recognizable at a glance as a Kosher Phone. Since its release, the Kosher Phone has been warmly embraced by those who want the convenience of a cell phone, without any of the associated potential hazards.

An additional benefit to Kosher Phone is that it runs on a SIM card, allowing it to function anywhere in the world. Users of GSM based carriers can use the Kosher phone with their own monthly plan and Kosher Phone Wireless offers extremely attractive monthly plans, giving users even greater flexibility. Among the many popular plans available are a $30 monthly plan which offers unlimited nationwide calling and a $50 monthly plan featuring unlimited calling, both nationwide and to landlines and cellular phones in Israel, Hong Kong, China, Portugal and Singapore. The $50 monthly plan also includes free unlimited calls to landlines in 45 other countries including Canada, Mexico, the United Kingdom and India. Both plans are available with no sales tax, no contract, no credit check, no activation charge and existing phone numbers can be easily transferred to a Kosher Phone free of charge.

The best part about this phone is that texting and internet are blocked internally. Most other similar phones have those features disabled through the network and it is possible to call the carrier and have that reversed. With these phones, even an experienced hacker would be hard pressed to hack this phone.

Kosher Phone has no camera, no Bluetooth capabilities, no memory card slot and cannot be connected to a computer. The phones are also usable worldwide.
