I have heard of Kosher phones. What do the classic sources (preferably Rishonim or earlier) say about the preferred type and brand of cell phone?

This question is Purim Torah and is not intended to be taken completely seriously. See the Purim Torah policy.

The rule is:

שלא יוציא אדם דבר מגונה מפיו ולעולם יספר אדם בלשון נקייה

Never use a Magna and always use a Nokia.


Hashem himself tends to favour a Windows phone as it says:

משגיח מן החלונות - He watches from his Windows [phone]

    Nonono! God Himself tells us to watch out for windows phones, as in to avoid them!

A Motorola RAZR is assur, as the paseuk says "you shall not take a RAZR to the corners of your face."

    So you can't take it to your face, but are you allowed to use it with a bluetooth headset? I would say not because "chachlili einayim miyayin ul'ven shinayim mechalav" -- teeth must be white

  • @kenzein in any case, the RAZR is certainly not the preferred cell phone. And any good Jew should avoid it just like any good Jew should have a long, white beard.

From davening:

וּבְסֵפֶר חַיִּים, בְּרָכָה וְשָׁלוֹם, וּפַרְנָסָה טוֹבָה , נִזָּכֵר וְנִכָּתֵב לְפָנֶיךָ, אֲנַחְנוּ וְכָל-עַמְּךָ בֵּית יִשְׂרָאֵל, לְחַיִּים טוֹבִים וּלְשָׁלוֹם.

לחיים טובים is clearly a reference to LG, which stands for "Life's Good".

LG: Life's Good


The gemara in Kesubos tells us that one reason that a bas ysirael ham'oreses l'kohen can't eat terumah is "mishum simphone", indicating that any phone with a SIM is problematic.


1 Kings 18:24 "And call ye on the name of your gods, and I will call on the name of the LORD: and the God that answereth by fire, let him be God. And all the people answered and said, It is well spoken."

It might appear that the LORD uses the Amazon Fire. At least worth considering.
Although, since I'm not an expert in Hebrew, it may be a slight stretch.

    Stretches are what make Purim Torah into Purim Torah :)

A.K.A. Pella, certainly one of the Rishonim of Jewish a capella, provides two opinions.

My phone's hashgacha's now uncertified
The vaad found out that Siri's not a guy
They won't let me connect to my Wifi
'Cuz Verizon's router's not ten t'fachim high
So i'm at a payphone

They also say:

Ay ay ay ay
You need a kosher phone.
Ay ay ay ay
You need a glatt kosher phone.

Glatt means "smooth", clearly referring to a Samsung Smooth cellphone.

This answer inspired me to create a Siri-ous (groan) question about it! "Siri, sing to me" - Kol Isha?


Tosfos Taanis 29b says that a Tapuach is an Esrog. The Torah calls the Esrog a "Pri Etz Hadar" (a beautiful fruit).

If Apple = Tapuach

and Tapuach = Esrog

and Esrog = "Beautiful"


Apple is Beautiful!!

PS. If you're going to tell me that the iPhone is the tree, I'm going to say that the two taste the same (according to Rashi to Leviticus 23: 40).



One should not have an iPhone, as the verse in Divrei Hayamim I 21:13 says quite clearly:

וביד-אדם, אל-אפל

In the hands of man there should not be an Apple

So Apple phones are out.

(And those who are exceedingly pious should avoid Macs and iPads as well.)


The best phone is a Sandalphone. It's what Metatron uses.

    Yes, but using Metatron as a source is why Acher became a heretic (chagiga 14). Again, that strikes me as a counter-recommendation.

Urim and Thummim, why not use the recommended ones?

    Unfortunately only the High Priest is allowed to carry that one ;-).

    @Yishai: Is the K''G the only one allowed to carry it, or to use it? Commented Mar 21, 2016 at 14:27

To the contrary of what’s been previously suggested, Apples should be used. The passuk says (Devarim 20:19):

כי האדם עץ השדה

For a man is a tree of a field

So when using a phone, which in essence takes the place of the person to whom one is speaking, the phone must be from a “tree of a field.” Therefore, one must have an Apple iPhone, and the carrier must be Orange. For those of us in the States, perhaps AT&T is recommended, as they bought out Bell Telephone Company and is thus reminiscent of bell peppers.
