Im not too sure on whehter Huawei have the contract now, either way their network is not what it used to be pre-iphone era. Too much strain no investment, rather a mast sharing deal with Voda to save money I suspect.
then the addition of giffgaff and Tesco furhter strained the network! and by the way Telefonica the parent company of O2 has £57 billion defecit which it needs to reduce so I very much doubt there will be money invested just ways to make money
