## Product: Samsung Galaxy S26 Ultra Unlocked 512 Gb

The unlocked [Samsung Galaxy S26 Ultra](https://www.amazon.com/dp/B0DQMCN6RV?tag=shopsavvy01-20) works with all major US carriers and most international networks.

- **T-Mobile** (5G sub-6 and mmWave)
- **US Cellular**
- **MVNOs**: Mint Mobile, Visible, Cricket, Metro, Google Fi, and others

## 5G Coverage

The S26 Ultra supports both 5G types:
- **Sub-6GHz**: Wide coverage, faster than 4G
- **mmWave**: Ultra-fast speeds in limited areas

## SIM Configuration

- One physical nano-SIM slot
- eSIM support
- Dual SIM capability (physical + eSIM)

Both lines receive calls and texts simultaneously. Data uses one line at a time.

## Locked vs Unlocked

**Carrier-purchased phones:**
- Locked for 60-90 days
- May have eSIM restrictions
- Unlockable after waiting period

**Unlocked phones:**
