purported phone number at the bottom, Israelis use the same numerals as we do. Not good at reading Hebrew, and not in the font given but my best efforts are:

Rsmelee Rmrmmh (Perhaps Ran's full name?)

In black circle for sender icon, RR

In phone number line Ks (or sh) lh mh s(or sh) l e. (that "W" thing can be either an S or a SH)

Oh, there are generally no vowels written, you have to stick whatever vowel sounds you can deduce between the consonants. Read from right to left. Very difficult language.
