GPP SIM interposer is a great solution for your iPhone 4S and 5. It will unlock your iPhone for any carrier anywhere in the world, including the United States. It sits in the sim tray beneath the desired sim card and takes about 10 minutes to setup. It’s cheaper than most factory unlocks and works flawlessly. Unlike other SIM interposers, for example, RSIM, Apple is less likely to patch it in every new iOS version thanks to the skilled developers of the GPP.

All the benefits:

Works on all GSM and CDMA iPhone 4S, 5, including Sprint and Verizon.
Does not void your warranty.
Works on bad ESN Sprint and Verizon iPhones.
Low power consumption.
Allows you to use any carrier anywhere in the world.
Apple is less likely to patch the GPP SIM interposer (Applies to GPP only).
Whats the difference between a GPP SIM interposer and a factory unlock?

A GPP sim interposer WILL unlock any iPhone 4S, 5 and allows Sprint and Verizon iPhone holders to use any carrier in the United States, unlike factory unlocks, which only unlocks Sprint and Verizon iPhones for international use. European carriers and a few others are very strict about allowing factory unlocking of iPhones, therefore a GPP SIM would be a great alternative because you unlock the device yourself, not the carrier. However, factory unlocks are permanent but the GPP SIM interposer has not been patched by Apple. Every new iOS that’s been released from iOS 6 to 6.1.3 has been compatible with the GPP.
