ikinci sorunuza devap vereyim:
When phone numbers are published for use abroad they typically include the country calling code, but show a plus sign (+) prefix in place of any international call prefix, to signify that the caller should use the prefix code appropriate for their country.[2]
Many phones allow this "+" to be entered in their saved number lists, often by holding down the '0' key (most GSM mobile phones) or with two consecutive presses of the * key. When making a call the system then automatically converts the "+" to the correct international prefix, depending on where the phone is being used, which enables callers to use the same stored number from any country.[1]
