Hey! It's great to hear from you. We appreciate you taking the time to share your thoughts with us. It looks like you reached out to share your experience with the Galaxy Watch Ultra. To activate the LTE service on a Samsung smartwatch, your smartphone must run on Android OS 5.0 or later, equipped with at least 1.5GB of RAM. A Wi-Fi or mobile network connection is also necessary during the activation process. It's important to note that these instructions are specific to LTE models of Samsung smartwatches. Upon pairing your watch with your phone for the first time, you'll be prompted to activate your carrier's service on the watch. This process is completed through the Galaxy Wearable app, accessible by navigating to Watch settings or the Home tab, then tapping on Mobile plans. The app will search for an eligible LTE network, following which you'll need to follow the on-screen prompts to finalize the activation. Ensure your phone has a SIM card inserted to proceed. If the watch was initially set up without a phone, activation can still be completed directly on the watch. We hope that these steps help get this resolved so that you can enjoy all the features that this watch offers from sleep tracking to energy scores. If this does not resolve what you are experiencing, please reach out to us at Samsung Support for further assistance. -Kelvin
