Huawei-built phone masts and peripheral things like that can stay, but BT has a long-standing commitment in place to not use equipment from the supplier at the very core of its network, due to the unspecified potential security risks of handing an overseas company the keys to your whole network.

Huawei told The Reg it had "been working with BT for nearly 15 years".
The British company also confirmed it is removing Huawei's hardware from use in its existing 3G and 4G networks, first revealed by theFinancial Times this morning.
The US, Australia and New Zealand have all moved to bar Huawei's equipment from 5G networks, and the head of the UK's secret service, Alex Younger, warned this week that the United Kingdom must decide whether to do the same.
