For the next 2 weeks, I will travel to Texas, US. I'm from Vietnam and bought this phone directly from the Samsung official local store, I wonder if I can use 5G UC from T-Mobile on my phone since this is an international version and supports n2/n25, n41 5G UC band from this mobile phone carrier.

T-Mobile's 5G UC relies heavily on the mid-band spectrum, particularly band n41 (2.5 GHz), which is a crucial component of their 5G UC footprint. T-Mobile also utilizes other bands for 5G UC, such as n2/n25 (1900 MHz), n258 (24 GHz), n260 (39 GHz), and, n261 (28 GHz). Your international Samsung phone supports n2/n25, n41, which are key bands for T-Mobile's 5G UC. It's always wise to review your T-Mobile plan details to understand your international roaming features and any applicable charges. Be mindful of your International Pass (if any) and Wi-Fi calling options. Before traveling, contact your carrier to confirm that your plan supports international roaming. Safe travels and enjoy your stay in Texas!!!

You should be able to. If 5G is turned on and connect to 5G towers, you shouldn't have an issue.

T-mobile has an international plan for customers and a price list for calls in many countries without roaming fees, US is one of them. Contact tmobile for details. Yes Tmobile 5G works in major cities and many rural areas, they have a map of 5G coverage in the US and it's large.
