Dialing Procedures

Domestic Calls

  • Landline to Landline: Dial the 7-digit number directly (e.g., 320 1234).
  • Landline to Mobile: Dial the 8-digit mobile number directly (e.g., 743 1234).
  • Mobile to Mobile: Dial the 8-digit mobile number directly (e.g., 743 1234).

International Calls

  • Outgoing: Dial 00 followed by the country code and the subscriber number. For example, to call the United States, dial 00 1 XXX XXXX.
  • Incoming: International callers should dial +691 followed by the 7-digit or 8-digit subscriber number (e.g., +691 320 1234 for a fixed-line or +691 743 1234 for a mobile).

Number Portability

  1. Validation: Ensure phone numbers conform to the structure and length described above using regular expressions.
  2. Formatting: Always include the country code (+691) when storing or displaying numbers internationally.
  3. Dialing Rules: Implement logic to handle both domestic and international dialing procedures correctly.
  4. Portability: Be aware that number portability is not supported, so numbers are tied to the original operator.
