missold EE contract for US roaming - it didnt work. I didn't discover until I needed to do a presentation on a smoking gun about IP Theft when I worked on pioneering comms for GEC. Huawei was a startup and the ambitions driven by the hate of the UK for suppressing China during the opium wars.
Obviously the parent company is BT who convinced the PM to allow Huawei to snoop across the five eyes networks. I wish I was wrong, but developing and running predictive comms networks and management systems since the 1980s i am not as I used to hack most systems to get them working and it was a black art. Now anyone with rudimentary skills can. Anyway despite me complaining about not being able to use EE, they have sent threats and involved a collection company to terrorise us. I cancelled within a week, but was told to return from the US to cancel in store in the UK within 14 days. don't use BT and EE and beware if you're involved with Defense/Defence that BT companies are barred from new sensitive contracts.
