usually required to set the parameters.
Parameter Description
Three-character currency code (e.g. "GBP", "EUR"). If the currency name is longer than three characters, all
characters will be cut off after the third position. Before they are written to the SIM Card, these characters are
converted to the standard GSM alphabet.
Price per unit; dot is used as a decimal separator (e.g. "2.66"). The length is limited to 20 characters. If the string
length is exceeded, the command is terminated with an error. This string may only contain digits and a dot. Lead-
ing zeros are removed from the string. The minimum and maximum value are determined by the structure of the
SIM-PUCT file. The maximum price per unit value is 999 999 999.00. When successfully entered, this value is
rounded to maximum accuracy.
Note: Due to storage in mantisse (range 0-4095) and exponent (-7 to 7) it is possible that rounding errors occur.

limited to 8 characters. If this value is exceeded, the command terminates with an error message. If the PIN2 is
incorrect, a CME error (+CME ERROR: incorrect password) is output.
