US Mate 10 Pro may feature single-SIM slot, VoLTE support on AT&T and T-Mobile

New rumors have surfaced regarding VoLTE support and possible lack of a dual-sim slot for the US Mate 10 Pro.

Published onJanuary 25, 2018

The front of the HUAWEI Mate 10 Pro.
  • HUAWEI Mate 10 Pro and Mate 10 Porsche Design rumored to feature single-SIM slot in US.
  • VoLTE support expected for AT&T and T-Mobile, as well as VoWifi exclusively through AT&T.
  • US models set for release on February 18th.

In the aftermath of CES 2018, all of the focus on HUAWEI has centered on how its long overdue debut in the US carrier market and expected partnership with AT&T went up in flames at the last second. As a result, it’s been easy to forget that HUAWEI is still bringing a flagship phone to the US market.

The unlocked Mate 10 Pro is set to retail for $799 from February 18th, as well as the special edition Porsche Design Mate 10 which will set you back a hefty $1,225.

Both models are a known quantity at this point – you can read our full review of the Mate 10 Pro here, or check here for our less-than-complimentary look at the Porsche Design variant – but there are certain specification details that have yet to be confirmed.

HUAWEI P20 and P20 Pro: all the rumors in one place (Updated March 19)

Now, thanks to an XDA-Developers forum member with a solid track record of HUAWEI/HONOR leaks, we now have a better idea of what to expect when our Best of Android 2017 winner arrives in the US.

Unlike the dual-sim Mate 9 that launched in the US last year (and the international Mate 10 Pro), the unlocked Mate 10 Pro coming to Best Buy, Amazon, and other select retailers will reportedly only feature a single SIM card slot.

The leaker also suggests that both the Mate 10 Pro and Porsche Design Mate 10 will both support VoLTE and Wi-Fi calling (VoWifi) on AT&T, while T-Mobile subscribers will only have access to VoLTE services.

Apparently, the models that will be sold carry the model number BLA-A09, which matches unreleased firmware for devices originally intended for AT&T’s retail channels.

Are these unlocked Mate 10 Pro phones retooled AT&T models? That’s the opinion of the aforementioned XDA user known as “duraaraa”, although there currently isn’t enough evidence to confirm these suspicions. As with any unconfirmed reports, it’s best to take all of the above with a pinch of salt until we have the phone in our hands.

There’s also no word on LTE band support, but it’s worth noting that both Mate 10 variants won’t work on CDMA networks such as Verizon or Sprint.

Would you be disappointed with a single SIM card slot, or are you still looking forward to picking up a Mate 10 Pro next month? Let us know in the comments.
