The request was made by the operators of the Cayman Islands, that formed an operator consortium:
- Cable and Wireless trading as LIME;
- Digicel Cayman Islands
- Westtel Ltd. Trading as Logic
The solution implemented on the Caymans Islands is an Centralized Database solution with inter operator messaging. It follows the standard number porting process for Fixed and Mobile, with IVR and SMS validation solutions in place. The project started in February 2011 and number portability went live on 20 February 2012.
