Safest Solution
Stealth SIM requires no modification of the baseband on your phone. This makes it the safest way to unlock your phone.

Modifying your Baseband invalidates your warranty. But worse still it is the most common cause of damage to iPhones. Attempts to modify the Baseband can trigger security mechanisms which can render your phone useless, commonly referred to as bricking. Moreover, even if your phone works initially, future updates from Apple could brick your phone.

This has happened in the past, and people have been left waiting for updates, with no guarantee any would be forth coming. The corrupted Baseband would also render your warranty worthless.

With Stealth SIM, should you need to utilize your Warranty, simply restore your phones firmware with iTunes and follow Apples warranty policy.

Simplest Solution

StealthSIM is the simplest solution to unlocking any iPhone. You don't need to worry which version of phone you are buying. Simply purchase a phone and follow the instructions on the support page of the website.

Since the Baseband is untouched you don't need to worry about patches you are applying to secure areas of your phone. You simply need to follow the activation procedure (Jailbreak), install your SIM using StealthSIM and begin enjoying your iPhone.

Secure Solution

With StealthSIM there is no need to share your IMEI with any third party. Or install software on your Baseband which you may not be able to remove if the group that wrote it disappears.
