The recent nationwide operation, dubbed Operation Signal Break, "dismantled critical command-and-control infrastructure used to perpetrate large-scale telecommunications fraud across the United States," ICE said in a July 24 statement. SIM box operations are estimated to result in losses worth $15 million annually to Americans, according to ICE. The SIM box then uses one of the local SIM cards to place a new local call to the recipient. In total, 68 SIM farms used to facilitate fraudulent texts and calls have been disrupted across 15 states. In an international case of SIM box criminal operations, Europol announced in October 2025 that it had taken down a cybercrime-as-a-service criminal network that provided SIM box services to criminals worldwide.
