    Hi all,

    Hoping to get some expert advice here. I don't know as much as I'd
    like to. What would cause a phone (in this case a nokia 3650) to
    display a 'sim card reg. failed' message besides a blacklisted IMEI?
    I just sold a guy my phone and he claims he can't get it to work on
    his network. I bought the phone directly from AT&T (it's been
    unlocked since, I tested it with another SIM) and was using it just a
    week before I sent it to him so I would be VERY surprised if the IMEI
    is blocked. From previous postings on this group I get the impression
    that it could be caused by a faulty sim, inactive sim, etc. Are there
    any other common (or uncommon) causes? Are there ever SIM
    compatibility problems, or weird things providers do with their SIMs
    that might prevent them from working with certain phones? I work in
    tech support so my experience is that the problem is usually between
    the chair and keyboard...or the chair and the keypad in this case.
    I'd like to have all the information available so I can figure out
    whether he's just not smart enough to make it work (and advise him) or
    if I need to take the phone back (although I'll probably end up
    letting him return it either way).

    Thanks in advance for your replies.

    I had a similar problem with a nokia 6230 and orange sim. I kept getting sim
    card registration failed. Turned out to be an incompatability with the phone
    and the newer 64K type sim card that orange had issued me with. I had the
    sim replaced and message went away.
