It is difficult to know what to believe when it comes to the charges leveled against Huawei and ZTE. The accusations against the companies, which involve their alleged capacity to conduct electronic espionage for China and their relationships with China’s government, are serious and plausible but also largely unproven.
Agreed, I own a Huawei MiFi. But untill I have seen proof that both companies are not using their equipment for espionage I won’t endorse them for large scale infrastructres, certainly not public.
The only problem is that the existence of backdoors is much easier to proof than the lack there of. The latter is largely based on trust.
