    I have a locked Cingular Treo 680 and I roam in Europe a lot. With every other locked phone I ever had I could choose my network when roaming. How do I do this with the 680?

    I ran into an issue where a supposed Cingular "partner" blocked all my GPRS and GSM calls. If I happened to get on another carriers cell everything was fine.

    Thanks

    Hmmm... I press the menu key and there is nothing called "network" .... any chance Cingular removed it? Or do you need to give dumb 'ol me some more instructions?

    I have "Phone V3.0A"

    Thanks

    This is a provider specific function. Cingular removes it from the SIM menu options. AT&T used to let you do this (back when Cingular was AT&T, I guess they're AT&T again...).

    So basically you're stuck roaming on whatever provider Cingular has agreements with. You can thank them for that.

    Your option is to get a local SIM, I've yet to find a european SIM that doesn't let you select network.

    Cingular can send an update to your sim, tell them you need to be able to roam by choice - they did this for me on my old phone. I could only choose networks when outside of the USA, don't know how they managed that but they did.

    IIRC, that's supposed to be the way things work. I bet the OP's SIM didn't get reprovisioned properly when international roaming was enabled...

    My useful post is #2 in this thread. #7 is useful for people who are still considering buying a phone. Both of these are more useful than your last post

    Huh? Cingular's locking out of network selection is done by the SIM, not by the phone. Even unlocked phones honor the setting on the SIM that hides/disables it, unless they're hacked...

    Is there a hack that gets around the blocked network menu for Cingular sim cards?

    There's one for the 650, but I don't think anyone's figured it out for the 680.

    I had an unlocked 650 and upgraded to a 680. Does this mean that my 680 is also unlocked? The 650 was unlocked with a subsidy unlock code provided by Cingular.

    The lock is on the phone not the sim. If you bought a phone from cingular it's still locked till you unlock it.

    To reiterate:
    I had a locked Treo 650. I called Cingular and they gave me the Subisdy Unlock Code after I gave them my IMEI for my 650. Applied the code and everything was fine. Two years later, I bought a Treo 680 from Cingular to replace my 650. I took the SIM out of the 650 and use it in the 680. Phone works fine. Is my 680 unlocked? I requested a new unlock code from Cingular on two occassions and was told that it would be emailed to me, but I have never received one. That was more than a month ago. I just spent 50 minutes on the phone with Cingular and was told that I didn't need and wasn't entitled to an unlock code since my phone was "active" with Cingular. The agent said the only reason I would need an unlock code was if I wanted to leave Cingular and switch to TMobile or some other GSM carrier.
    Numerous poster here say that the unlock code is SIM based and others say the unlock code is phone based.
    HELP!!!
    TIA

    Two different types of locks -
    SIM locks we are talking about are functionality restrictions the SIM keeps the phone from performing - like manual network selection.

    subsidy unlock - phone based lock that locks the phone to using the carrier from which you purchased the phone. This is the lock you did on your 650. You don't need it unlocked unless you plan to use other SIMs when you travel or change carriers.

    Unlock has nothing to do with the SIM, it is a hardware thing. The reason your Locked Cingular 680 worked is because you put in a Cingular SIM. If you had a locked Cingular 680 and put a SIM from T-Mobile in it, it wouldn't work because the phone is locked into only working with Cingular SIMs.

    The rep from Cingular was almost right - the only reason you would need to unlock your phone is to use a different network. Cingular sees that as a threat, hence their hesitation to give you an unlock code. You can always tell a rep that you are traveling internationally and want to use an in-country SIM - that you don't intend to switch off from Cingular as your service provider...that might prompt them to actually give you an unlock code.

    Otherwise, either buy an unlock code (google or search these forums for recommended sites) or keep trying to get Cingular to send you one.

    Good luck

    Thanks to frantid and jsgreen. This time I called Cingular Tech Support, rather than Customer Service and requested my subsidy unlock code. I travel to France a great deal and that seemed to be the missing part of the equation. What a hassle.
    Again, thanks for the clarifications.
