If I Put My Samsung SIM Card in My iPhone, Will It Work?

By Robert Schrader

You can Insert a SIM card from a Samsung phone into an Apple iPhone to use the device with your existing service account. If you currently use AT&T with your Samsung phone, inserting the SIM card into any iPhone generates services. If you use the Samsung phone with a different carrier, on the other hand, its SIM card only works in unlocked, or "jailbroken," iPhones.

Step 1

Hold down the "Home" and "Lock" buttons at the same time to power the iPhone off. Place the end of a paper clip into the hole next to the SIM card tray, located on top of iPhone 3G and older models, and on the right side of the iPhone 4.

Step 2

Pop out the existing SIM card -- if there is one -- then place the Samsung SIM card into the SIM tray, face down. If you use an iPhone 4, only a small "microSIM" works in the device, so if your Samsung phone uses a standard-sized SIM, it won't work.

Step 3

Replace the SIM tray and power the iPhone back on. If a network name appears in the upper left corner of the screen, you can use the iPhone with the Samsung SIM card.
