Hi there Kind, thank you for taking the time to ask us your question about the Samsung Galaxy Watch8. The advertised U.S. version of the Galaxy Watch8 may have limited LTE functionality while traveling abroad due to this device being built with LTE bands specific to US carriers. We suggest confirming your country's network supports this device's specific bands. The Watch8 will still function for basic features like Wi-Fi and Bluetooth, however, cellular connectivity could be restricted or unavailable depending on the carrier's network compatibility. If you have additional questions for us, please feel free to reach out to Support. Thank you for being a faithful Samsung customer. - Debra
