Unlock your CDMA iPhone 4S to use on GSM networks
Unlock your CDMA iPhone 4S with the GEVEY Ultra S Multi-Network turbo SIM and use it on GSM networks around the world. Jailbreak is required in order to unlock your CDMA iPhone 4S with the GEVEY Ultra S Multi-Network turbo SIM and requires iOS 5.0 or 5.0.1 with modem firmware 1.0.11, 1.013, or 1.0.14.

True Plug-and-Play Unlock Turbo SIM for GSM iPhone 4S
Unlock your GSM iPhone 4S with the re-engineered GEVEY Ultra S Multi-Network turbo SIM. Our new technology takes advantage of a few new exploits that fully unlock your GSM iPhone 4S. It’s true plug-and-play functionality with no jailbreak required for your GSM iPhone 4S, so just pop it in and start calling.

Compatible with all GSM and CDMA iPhone 4S SIM Cards
The new GEVEY Ultra S Multi-Network is now a single interposer that works for both networks. It actually “learns” your network, so there is no need to select a specific GEVEY Ultra S Multi-network for your specific service carrier. Your new GEVEY Ultra S Multi-Network turbo SIM comes in learning mode, but after inserting it into your iPhone 4S with your SIM card, our technology learns your networks types and settings for a true plug-and-play unlock solution on GSM network iPhone 4S models.

One caveat of this exploit is that, if for some reason you need to change your current SIM with a SIM card from a different carrier, you will need to reset your GEVEY Ultra S with the reset SIM included with your genuine GEVEY Ultra S Multi-Network.
Beware of other solutions that claim to circumvent this issue. It is simply not possible when taking advantage of this new exploit in the iPhone 4S firmware.

No SIM Card Cutting or Physical Modifications
The new GEVEY Ultra S Multi-Network is engineered using the F981 chipset, which is more expensive but performs a whole lot better than cheaper solutions. We don’t manipulate, polish, or sand down cheaper microchips to make our SIM interposer small enough to fit, and there is no need for you to cut your SIM card or modify your iPhone 4S in any way.
Beware of counterfeit GEVEY products claiming to use the F981 chipset and selling for less than our rock bottom pricing. Most people won’t be able to tell the difference by visual inspection, but some cheaper, larger chips used in these solutions are sanded, cut, or polished to fit in your iPhone 4S. These solutions expose sensitive electronic components and are notoriously prone to overheating, short-circuit, and breakage.

Guaranteed Better Reception than Last Generation Unlocking Solutions
Now that we no longer take advantage of the old exploits, we’ve re-engineered the GEVEY Ultra S Multi-Network for enhanced signal strength with strong, consistent voice and data communication. Now there is no compromise in reception when choosing genuine GEVEY products.

No Need to Dial International Emergency Number 112
There is now no need to dial the international emergency number (112) during installation or when rebooting your iPhone 4S. Our learning technology allows for true plug-and-play iPhone 4S unlock solution.
Beware of solutions that require you to dialing an emergency number. This may violate telecommunication abuse policies and lead to service cancellation on some networks.

Decrease Power Consumption
The F981 chip set in our new GEVEY Ultra S Multi-Network is engineered to operate under the 3-volt standard. That means your battery will last just as long as it would without the GEVEY Ultra S.
Beware of counterfeit solutions claiming to use a similar chip set. We’ve invested the time and money to engineer our new GEVEY Ultra S Multi-Network with better power efficiency. This kind of technology can’t be duplicated or implemented on cheaper chip sets.
