How to unlock my iPhone 4S on software 6.1.3 for free?

I recently brought an iPhone 4S and its locked to vodafone carrier but I have a O2 SIM card. I have tried to do it through vodafone but they can't as I'm not the original iphone owner.

Hi, free unlocking is not possible for your iPhone 4S. By using software to unlock the phone sometimes the phone may get damaged (or) it will become useless.

So, I would suggest you to use the safe and secure to unlock your phone i.e;Remote Unlocking Service.
You can get this service at low cost from http://www.simpleunlocking.com/apple-iphone-4s/rs16wp9/ with easy step by step unlocking instructions and unlock it from Vodafone carrier. After unlocking it, you can use freely any GSM network SIM card like O2 SIM card. This is the fast and permanent unlocking service.

I don't think there's an iPhone Factory Unlock process for free. I suggest that you get an unlock service to unlock your phone and also to avoid issues that will lead to a non working phone.

  • Where can i buy iPhone unlock software? I would rather unlock phones myself as opposed to paying someone to do it for me. So what is it that they use? Is it a software they have downloaded? If so, how can I get my hands on it. If not, where can I possibly find the cheapest and most reliable unlocking service on the web.
