Re: can galaxy s4 be a phone as well as a tablet
What model Galaxy S4 do you have? Go into the settings and about phone for the model number. As mentioned above, you'll need to have active service either via a GSM or CDMA carrier, depending on the model S4 you have (not all are the same). As a tablet, yes. You don't need data services and/or the phone to be connected. Just use the device on WiFi. Note that you'll only have internet connection when connected to WiFi and/or a mobile hotspot.
