If your Samsung S4 is unable to act as hot spot with Straight Talk, simply check your network settings.

Straight talk or sprint
The Samsung Straight Talk phone has a menu allowing incoming calls to be blocked. It can be found as an option when the call comes in. An application can also be downloaded to do this.
From what I'm told, straight talk will be switching from Sprint to Verizon on this phone.

Yes as long as you use the straight talk sim and custom apn settings.
The Straight Talk service allows people to bring your own device. So, a Samsung Galaxy S3 should be compatible with Straight Talk, even if your phone was purchased through a carrier. For instance, if you purchased a phone through AT&T, and want to switch to Straight Talk, you can utilize the same AT&T network coverage if you pick a Straight Talk AT&T plan. Early termination fees may apply though if you choose to break off your contract to join Straight Talk.
