Hi, thank you for taking the opportunity to ask us your question about the Samsung Galaxy Watch8. Yes, the Galaxy Watch8 allows for calls and texts, but how it works depends on whether you choose the Bluetooth or LTE model. On the Bluetooth versions for instance, your watch must be connected to your Android smartphone via Bluetooth (or connected to the same Wi-Fi network with Remote Connection enabled) to make/receive calls and texts using your phone number. When it comes to our LTE versions, you can step out without your phone and still make calls, send texts, and use data using Number Share via carriers. Hope that helps! If you have any other questions for us or if you would like further assistance, please let us know by contacting Support. Thanks for being a treasured Samsung customer. - Debra
