The U11 is arguably the best flagship phone HTC has ever made, and it properly competes with the other great phones released in the first half of 2017. But in coinciding with HTC's general decline in the U.S. market, its partnerships to put phones in carrier stores have dwindled, leaving us with a single carrier "partner" here: Sprint.

That means if you want to use the HTC U11 on any other carrier, you'll have to buy it unlocked — both Amazon and HTC will sell it to you directly without any carrier shackles for $649. That's great for discerning consumers, but it has also led to questions — primarily, does the phone support our favorite giant carrier, Verizon? Well, yes, it does — HTC says so on its website. Confusion has set in, though, as we all dig through the specs and realize it doesn't have a CDMA radio.

Not having CDMA isn't the end of the world, nor does it preclude HTC from legitimately stating that the U11 is compatible with the Verizon network — let me explain.

Verizon's upcoming CDMA sunset

Verizon doesn't want to use its CDMA network anymore. It has confirmed that it hopes to effectively shut down the old network by the end of 2019. Once it does so, the remaining spectrum and towers currently in use for CDMA (which have been dramatically scaled back in recent years already) can be repurposed for other uses as Verizon turns LTE into its baseline network and moves on to 5G deployment.

Verizon doesn't want people using its CDMA network anymore, and you probably already don't.

For most people using Verizon today, CDMA might as well not exist. Its LTE network covers 98% of the country. As of Q1 2016, 92% of its network traffic was traveling over LTE — and remember that includes some legacy devices that only use CDMA. So there's a dramatically small (and decreasing) number of places without LTE coverage, and surprisingly close to 100% of network traffic by LTE-capable devices is running on the modern network.

Even if your phone has a CDMA radio, chances are you don't actually use it anymore. When your phone has an LTE connection available, it will use it for both data and calls across Verizon's network — other times, you may be using Wi-Fi calling. In 2017, CDMA offers a suboptimal experience — only to be relied upon when there is no other option. Yes those places where CDMA is the only option do still exist, but Verizon clearly doesn't think they'll be around much longer.

Reason says that it won't be long, then, before Verizon itself stops selling smartphones that have CDMA radios in them. Including the old technology for a network that won't exist in the reasonable lifespan of the phone (roughly two years from sale) doesn't make sense from multiple perspectives. Having a CDMA radio requires extra licenses and technology (read: money spent) in smartphones, and just continues to sustain a user base of people who will have a device capable of using a network that will soon no longer be available.

HTC did the necessary work

HTC isn't hiding the fact that the U11 doesn't support Verizon's CDMA network. Every radio, band and network the U.S. unlocked U11 supports is listed right on HTC's website — including LTE band 2, 4, 5 and 13 for Verizon. But this is still confusing to some because HTC says it supports Verizon while also not having CDMA — and for some people, that doesn't mean "full" support.
