Yes, you can use Galaxy Watch 7 or Watch Ultra without your smartphone. Initially, you have to pair your watch with the smartphone, and then you can use it. You will not get any real-time alerts or phone calls. Further, you need to be connected when you want to synchronize all your health data with the phone. Also, to get notifications, answer or receive calls, update the software, download new apps, or watch faces, you should connect to your phone.
If you use the LTE variant, then you don’t have to worry about all these things. Only once pair the Galaxy Watch 7 with the Samsung Galaxy phone or other Android phone, activate eSIM, and you can leave your phone at home. The smartwatch will transfer all your messages,Β emails, calls, and other notifications. If you are an iPhone user, then in any way you canβt use the Galaxy Watch or its functions.
