The Xiaomi Redmi Note 13 Pro+ 5G is indeed an unlocked device, but its compatibility with networks in the Americas has some limitations.

- Unlocked Status: The phone is globally unlocked and can be used with GSM carriers. However, it is not compatible with CDMA carriers such as Verizon, Sprint, or US Cellular.

- Network Compatibility: The device supports various 5G, 4G, 3G, and 2G bands, but the coverage might be limited depending on the specific bands used by your local telecom operators. Here are some of the supported bands:
- 5G bands: n1, n3, n5, n7, n8, n20, n28, n38, n40, n41, n66, n77, n78
- 4G LTE bands: B1, B2, B3, B4, B5, B7, B8, B12, B13, B17, B18, B19, B20, B26, B28, B32, B38, B40, B41, B66.

For optimal use in the Americas, you should check with your service provider to ensure the phone supports the necessary frequency bands for your region. Generally, it should work well with GSM carriers like T-Mobile and Mint, but coverage could be limited in certain areas if all the necessary bands are not supported.
