It was founded by the Behn brothers, Sosthenes and Hernan.[1] Originally, Puerto Rico Telephone Company eventually spawned ITT Corporation, which was founded by Sosthenes Behn.

Relationship with Verizon Wireless[edit]

Until 2014, Claro continued to offer a CDMA network for Verizon Wireless customers as well as legacy Claro customers. The CDMA network appeared as "Extended Network" coverage on Verizon[6] - meaning the majority of Verizon customers were able use it at no extra charge. Prepaid providers like Page Plus Cellular however had to pay roaming in Puerto Rico.


Data access for Verizon customers was at full speed. However, Claro deployed EV-DO before launching its GSM/UMTS network. As a result, Claro had the slowest CDMA coverage on Verizon Wireless at sub-3G 1xRTT speeds, peaking at 144-230 kbit/speed. Roaming customers would not access the EV-DO local network.


Data, like voice, was Extended Network coverage which had per-KB roaming charges on some older plans.


As of 2014, the former Verizon CDMA network has been shut down with Claro now using GSM, UMTS, and LTE exclusively. Verizon has since signed a 2G and 3G CDMA roaming agreement with Open Mobile, where Verizon customers can use its network without charge. Later on, Verizon has also signed another agreement with Claro to also allow customers use their LTE Network.
