My Factory unlocked iPhone 4s has Relocked after updating to ios7.1.2 from 7.0.4,what do i do?
My iPhone was originally locked to Vodafone uk which i got unlocked a month later from an IMEI unlocker website and i updated from ios 6 to 7 no issues but today suddenly it won't activate my sim card.
You will have to contact the carrier and tell them what happened. The can issue an unlock code.
The previous unlock which you made to your iPhone must not be a permanent unlocking method. So, probably the iOS update would have re locked your iPhone to its previous network. You have to unlock your iPhone 4S again. You can visit http://www.onlinegsmunlock.com/apple-iphone-4s/rs5wp9/ and get the remote unlocking service for your iPhone 4S. This method of unlocking an iPhone is safe, simple, affordable, quick and permanent. It doesn't require a jailbreak too.
First of all, your phone is (was) not Factory Unlocked. Factory Unlocked means it came from the factory unlocked, never having been locked to a specific carrier. Your phone was either unlocked, in which case you will have to contact the original company it was locked to for instructions on unlocking it and hope that works or you are stuck with a non-working phone because it was not unlocked but jailbroken, which will eventually render a phone useless when updates occur.
- Will updating my iPhone apps affect my phone speed as how updating the Operating System (OS) will? Currently I'm using the iPhone 5s on iOS 8.3 I know if I were to update my phone to the latest OS I may notice some slowdown on my phone's performance, since it may not have the "muscle" to handle certain functions. Many apps now are optimised for iOS 9 and/or the 6th generation phones. Will my 5s' speed performance slow down if I update my apps? Will the app's performance slow down?
- Will my factory unlocked ATnT iphone 4 not work for tmobile after ios7? I have a factory unlocked ATnT iphone 4. I currently use it for tmobile. I was wondering if I update it to the ios7, will my phone still function the same as before, or would it get rid of the unlock feature and no longer work with tmobile?
- Will an unlocked iphone 4S work for tmobile if it isn't factory unlocked? I want to get an iPhone 4S and my friend has the iPhone 4 unlocked but i'm worried that if i get it non-factory unlocked it won't work. My uncle tried to do it a couple of months ago and apple said that if it was factory unlocked every time the phone shut off or died it would reset. I was just wondering if the same thing would happen if it wasn't factory unlocked? So if I get it unlocked everytime it will shut off it will reset? That is what i'm worried about.
- Unlocked vs factory unlocked iphone? So I'm thinking about getting an iPhone but I wanted to know if I could take an unlocked iPhone to the Verizon store an them set it up for me? I have no clue what the difference between factory unlocked, unlocked, and locked iPhones are
