Function mobile

Generates a random mobile phone number with customizable prefix.

Creates a mobile phone number in the format: [prefix][3-4 digits][4 digits]. The middle section is 3 digits if the random number is less than 1000, otherwise 4 digits. The last section is always 4 digits, zero-padded if necessary. Commonly used for generating Korean mobile phone numbers or similar formats.

Example

  RandomGenerator.mobile();        // "0103341234"
  RandomGenerator.mobile("011");   // "0119876543"
  RandomGenerator.mobile("+82");   // "+8233412345"

  // Generate test user phone numbers
  const testUsers = Array.from({ length: 100 }, () => ({
    name: RandomGenerator.name(),
    phone: RandomGenerator.mobile(),
    altPhone: RandomGenerator.mobile("011")
  }));

  // Create international phone numbers
  const internationalPhone = RandomGenerator.mobile("+821");

  // Generate contact list for testing
  const contacts = ["010", "011", "016", "017", "018", "019"].map(prefix => ({
    carrier: prefix,
    number: RandomGenerator.mobile(prefix)
