According to the Federal Communications Commission (FCC), US telecoms companies urgently need more money to remove Chinese components from their networks. Almost 40 percent of US companies that have already received government aid need further support, FCC chief Jessica Rosenworcel told Congress. Some companies had warned that they might otherwise have to switch off their networks. The cost of removing Huawei and ZTE’s technology is estimated at just under five billion dollars. However, only 1.9 billion US dollars have been approved as part of the „rip and replace“ program.
