I'm way out of contract and I've decided to move networks onto a Sim-only monthly deal. Requested a PAC code and an unlock on 1st August from Orange. They quoted me 15-20 days. No sign of the unlock as yet, and they've not billed for it. They'll be getting a stern phone call tomorrow. Their customer service is a lot worse than it was when I signed up three years ago. Two questions : 1) Do Orange make a habit of dragging their feet on unlocks? 2) Can I use the PAC code and move networks or will I be unable to unlock the phone if the Orange SIM goes inactive before they get around to requesting it from Apple?
