The Huawei Mate 10 Pro was supposed to launch on AT&T and Verizon, the big announcement for this was expected at CES, although AT&T pulled out at the last minute.
According to a recent report, pressure was put on AT&T by US Congress not to sell smartphones from Huawei. Reuters is reporting that US lawmakers pressured AT&T to drop the handset at the last minute.
Lawmakers are also apparently pressuring AT&T to stop its collaboration with Huawei in its 5G network. According to the report, the Government has said that is AT&T and other companies work with Huawei China Mobile and other Chinese companies it could harm their chances of getting government contracts.
The government in the US claims that Huawei has ties with Chinese security agencies and that these agencies can access private communications via Huawei technology. There does not appear to be any evidence of this released as yet.
