Dont fool yourself. If you get a Huawei phone and use it with a U.S. carrier with any services by U.S. tech companies that can be back-doored or subpoenaed, then you could potentially have both the U.S. and China spying on you. It has already been proven in the past that these Chinese phones send considerable amounts of data to Chinese servers.

If you are someone working with a military contractor or the government(with any kind of security clearance) I dont think the U.S. would want you using a Chinese phone for obvious reasons
