Now enter all 5 values of subscriber data, value by value.
Whenever you entered one value, the phone display that the PIN was wrong and prompts for the next value.
If the value is less than 4 digits, add zeros in front of it to make it at least 4 digits long.
After all 5 values have been entered, the SIM starts emulating that subscriber data.
If one of the input values is out of range, the SIM card will emulate a fictitious number "3333333".
This is displayed on the phone. This means that the input was wrong. Check the values and start over again.
