## Quick Answer

If you're in the US: yes, you get mmWave. If you're buying an international model: no mmWave, but you still get 5G.

## What US Buyers Get

The US version of the [Galaxy S26 Ultra](https://www.samsung.com/us/smartphones/galaxy-s26-ultra/) includes the full 5G package:

- **Sub-6GHz 5G**: Works almost everywhere
- **mmWave 5G**: Ultra-fast speeds in select locations

You're covered on every major carrier—AT&T, Verizon, T-Mobile—with full 5G support across their networks.

## International Models

You still get 5G, just without mmWave. This matters less than marketing suggests.

## Does mmWave Actually Matter?

Here's the honest truth: mmWave sounds amazing in ads but has significant limitations:

**Where it works great:**
- Sports stadiums
- Convention centers
- Major airports
- Some downtown city blocks

**Where it doesn't work:**
- Inside most buildings
- In suburbs or rural areas
- More than a few hundred feet from a tower
- Behind pretty much any obstacle

When you do hit a mmWave signal, speeds can exceed 1Gbps. But Sub-6GHz 5G—which both US and international models have—delivers 100–500Mbps reliably across much wider areas.

## Which Carriers Work?

All of them:

- **AT&T**: 5G and 5G+
- **Verizon**: 5G Ultra Wideband and Nationwide 5G
- **T-Mobile**: Ultra Capacity 5G and Extended Range 5G

Both standalone (SA) and non-standalone (NSA) network modes work.

## The Bottom Line

If you're in the US and occasionally visit stadiums or downtown city centers, mmWave is a nice bonus. If you're international, Sub-6GHz 5G will serve you well—you won't miss mmWave in daily use.
