    "you need enter the phine number

    And you need to form all that into the appropriate AT Command - as described in the links already given.

    "putchar (26);
    or
    putchar (0x26);"

    They can't both be correct, can they?!
    Either the hex is right and the decimal is wrong, or vice-versa

    It is left as an exercise for the student to look it up in an ASCII chart and determine which is the correct code...
