Wireless local number portability is a regulatory mandate requiring cellular carriers to release a subscriber's phone number to a competing carrier upon request. The process involves updating central routing databases so that incoming calls are directed to the new provider's switch. It removes the friction of switching carriers and forces networks to compete on service quality rather than holding a user's identity hostage.
The WLNP request failed because the billing zip code on the porting form didn't match the old carrier's records.
