completely removing Huawei from 5G is such a problem. So many masts have Huawei 4G.
More interestingly, lots of Three masts are being swapped from previous vendor (e.g. Samsung, or others) to Huawei for 4G, and then having Huawei 5G added.
The Huawei decision impacts Three quite hard, and will be delaying other upgrades. It hits all the networks, others tend to have regions by make, e.g. a Huawei region, an Ericsson region, or a Nokia region.
Generally one of the big delays is getting 10 Gigabit connections to a site, but the Government didn't help.
