Liberty Mobile Puerto Rico Inc issued these blocks several years ago. Customers swap carriers every few years, so Liberty Mobile Puerto Rico Inc probably no longer holds them. Try calling any number you're interested in. If a person answers, you've found the current owner and can negotiate with them.
A long shot: if you'd like a watch in case we ever gain access to Liberty Mobile Puerto Rico Inc's inventory directly, you can register your interest. We don't currently have visibility into number changes within carriers, so don't count on it.
