Huawei was so close to inking a distribution agreement with AT&T that the Chinese company has already manufactured carrier-specific Mate 10 Pro units. Unfortunately, after AT&T caved in under political pressure, the US version of Huawei Mate 10 Pro will have to be repurposed and sold unlocked.

For those of you who still want to buy the Mate 10 Pro even though it won’t be available at any of the US carriers, here are a couple of things that you need to be aware of before making your purchase.

First off, the US version of Huawei Mate 10 Pro will offer single SIM support, unlike the model that will be launch in other countries which will have dual-SIM support. Then, the flagship will come with VoLTE (voice over LTE) support on both AT&T and T-Mobile, but it will only feature AT&T VoWiFi (voice over WiFi).

The same goes for the Porsche Design Huawei Mate 10, which will be much more expensive than the regular version. Huawei Mate 10 Pro will be available for pre-order in the US starting on February 4 for $799, while the Porsche Design model will sell for $1,225.
