Before returning to Canada, I bought a Galaxy Siii outright from a store in Melbourne Central. The phone was unlocked even though it was Optus branded. We attempted to get sim cards from the cheaper phone company in Toronto, but neither of our phones would connect to the network. Our next stop was at one of the big three companies, Bell, where thankfully our phones did work on their network.
About a year ago my phone wouldn't turn on even with a different battery. Bought in Australia, but died in Canada. The sadly meant that Samsung Canada wouldn't do anything to help me fix the problem. The phone was returned to Australia and now has a new home. I bought another phone outright from Bell, my service provider, since I didn't want to give in and go on a three-year contact. You would think buying a phone at full price and not being on a contract would mean the phone would be unlocked, but no. They could unlock it for $56, but that required call them up to do it.
We attempted to unlock it following instructions on the internet - that failed. Downloaded an unlock app - model not supported. Fine, I'll give in and get them to unlock it for a price - ha! The first time I phoned, the call disconnected after 25 minutes on hold. The second time I waited 55 minutes for an unlock code that didn't even work. The third time was a 80 minute wait. Apparently his manager is looking in to it and will get back to me within a few days.
Cam paid to get an unlock code from the internet that thankfully worked. He did spend awhile trying to do it for free, but none of his efforts were successful. I attempted to get an unlock code from the same site, but you can probably guess how that turned out. They sent me the same code that Bell had given me the day before. I'll have to send them a video of our attempts to use the code as proof to get a refund.
Still locked. Should have gotten a nexus.
