In the past, unlocking iPhone is not easy. Hardware unlocking was previously the only known method to unlock the 5S which requires breaking open the phone. Naturally, this resulted in more disaster than success. Apple then introduced software coding to lock the phone to network operators. So coders designed software to disable this lock. To unlock the phone you have to jailbreak it first to insert the third party code. This resulted in the cancellation of warranty and the software doesn’t work all the time. The most popular method to unlock iPhone is to use the factory unlocking method which makes it easy for anyone to unlock.
One of the reasons for the popularity of the factory unlock is that it doesn’t null the warranty. Even though you make changes to the locked phone to unlock it, the Apple warranty is not affected. This is because the factory unlocking method doesn’t affect the Apple proprietary pieces of the phone. When you search for ways to unlock an iPhone 5C or 5S device, most of the methods interfere with the way Apple places a lock on the phone. The factory 6S unlocking works outside of the phone by adding the IMEI number of the phone to the unlocked database that is done by a trusted service like Unlock iPhone Den(site). Both the hardware and software of your iPhone remains unaffected using factory unlocking method. To unlock the iPhone 5S, you have to trust a third party company to add the IMEI number of the phone to the Apple database. Only Apple and other carriers have access to this database. You don’t have to download any software or send your phone to an unlocking provider to complete the unlocking procedure. As no changes are made to the hardware, you can update iOS or change the firmware and baseband according to your wish. Updating to the latest iOS 9 firmware allows you to enjoy new features with zero security risks.
If you choose to factory unlock the 5S using any method other than factory unlocking, then you have to constantly worry about the phone getting relocked at any time. Some providers provide only carrier unlock that allows you to change your service provider as long as you use your phone in the same country. This means that international travel will be difficult and your phone will relock when you go to another country. Factory unlocking eliminates this uncertainty as it works in all countries with all GSM operators. You can make changes to the iOS 9.0 and firmware without worrying about losing your unlock.
Many people unlock iPhone 5S because unlocking boosts the resale value. The factory unlocking method unlocks your phone permanently and so, you can get a better price for a factory unlocked iPhone 5S. New iPhone’s are released almost every year and there is really no reason to stick with your old phone. You can generate serious cash by reselling factory unlocked iPhone’s so that you can upgrade to a newer model.
