    I've done alot of searching and this seems to be asked alot without a definitive answer.

    I purchased an 8900 of ebay that was supposed to be unlocked from T-Mobile UK, however it simply says invalid sim card -sos mode with the several sim cards tried. I've tried to check or get it unlocked if needed by going to Advanced Options-Sim Card but theres nothing there, just 'No Valid Sim Card'.
    I'm trying to use it with an Optus Australia sim.

    I'm a bit stuck and here and am contemplating asking for a refund if I can't get around this but the seller is not responding.

    Sounds like the phone is not really unlocked. You will need to use the phone's original carrier SIM card (T-Mobile UK) to get to the menus needed to unlock the phone. You might want to contact one of the companies that post on the forums here for unlock advice.

    I encountered the same problem when I bought my 8900,when you're in advanced options go to sim card and type in mepd,if any of the options say enabled it isn't unlocked.Like merlin said there's a ton of unlocking companies on here and they're more than happy to help
