Instance Method Details

#msisdn(options_hash = {}) ⇒ String?

Validates and converts an MSISDN in the string to the required format.

Examples:

Convert to an international format.

"31234567".msisdn(:country => "BH", :format => 'international')
"0097331234567"

Convert to a 10 digit mobile number.

"+919846819033".msisdn(:format => 'local')
"9846819033"

Options Hash (options_hash):

  • :country (String) — default: 'IN' —

    The ISO 3166 code for the MSISDN’s country.

  • :format (String) — default: 'local' —

    Either ‘local’, ‘international’, ‘country’, ‘plus_country’.

#msisdn?(options_hash = {}) ⇒ Boolean

Validates an MSISDN.

Examples:

Validate an Indian MSISDN.

"9846819033".msisdn?
true

Validate an non-Indian MSISDN.

"+919846819033".msisdn?(:country => 'CA')
false

Options Hash (options_hash):

  • :country (String) — default: 'IN' —

    The ISO 3166 code for the MSISDN’s country.
