Patience is important! It took almost 2 weeks to unlock my daughter’s iPhone 6S from O2 which is unusual according to the updates received. BUT at every stage you are updated and can check the tracker to find out how long it will take. It’s also important to read the small print. There are two stages to the process and two payments. The first stage is to ensure you’ve entered the right information for the phone, the second is the unlock stage. Overall the process is really easy, you’re kept up to date as things progress, you can check unlock status anytime you want to, and the estimated time left to unlock is shown on the status. I’m really happy that the phone is now unlocked, my initial disappointment was purely because I hadn’t read the instructions. 😎
