Huawei filed a lawsuit with a Lisbon court against the resolution at the end of August, seeking "protection of its legitimate interests and legal rights under the law". Portugal's main operators, Altice, NOS (NOS.LS) and Vodafone (VOD.L) have already said they will not use Huawei equipment in 5G core networks, amid European and U.S. concerns that Chinese involvement in critical infrastructure could compromise security. "It is work that is ongoing and we hope that it will be carried out successfully. We can assure the Portuguese that we are also working together with the operators", he added.
