    They're rolling out GSM in the next month with phones that use sim cards as well.. Do you think the treo could work on that system also?

    It depends. AT&T and Cingular are both in the process of converting their whole networks to GSM. The catch is that not all of it is necessarily going to be GSM1900. They already have huge investments in the 800MHz spectrum, so they've been able to create a new de facto GSM800 standard in the areas in which they don't hold 1900MHz licenses, but _do_ hold 800MHz licenses. If the network in your area is going to be a GSM1900 network, then the Treo will work. If it's GSM800, then it won't (unless Handspring makes _another_ version).

    If anyone hears anymore on this, please pass it along. I think the main thing from preventing my wife from using a Treo now is her contract with AT&T which doesn't expire until December.

    I swapped phones for a few minutes w/ a co-worker
    who had an AT&T GSM Sim...it worked in my
    visorphone, and my (voicestream) Sim worked in
    his prototype Ericcson. I don't see the Treo
    being any different. When _my_ order (a Treo 180g) shows up, I'll be able to confirm.

    Went to my local ATT wireless store and asked if we could exchange the sim card into "another" phone. The rep said that it would only work on AT&T phones. But what else would they say? I expected as much since they want us to buy their phones. But I'm confident it would work.

    Is there anyway to tell if they are using GSM800 or GSM1900 here in Phoenix?

    I wish their GSM rate plans were similar to their standard rates (free long distance, etc.)

    Although I really like at&t (best service I've had going through 2 other service providers in Chicago (Primeco and SprintPCS)) I'm starting to want to veer towards voicestream. AT&T told me over the phone that the GSM services will be charged per megabyte rather than out of your allowance of minutes. Oh well, I don't plan on getting one anyway until I check out the 270s..

    In some instances they may be correct - I've
    heard that some GSM phones you get "Free
    with activation" are modified to only work
    with that provider's service. So if you bought
    provider A's service, only a sim from A will work
    in it.

    HOWEVER - this doesn't mean that A's sim won't work in any GSM phone except one
    "made for" A's network. And, a generic GSM phone like the visorphone should work with voicestream/cingular/AT&T AFAIKAFAIKAFAIK.

    I don't think the Treo has a 'sim-lock'

    I had the same question. I live in Dallas, so I was able to convert my AT&T plan to GSM. The GSM plans and data rates are not very competitive right now. I think they are waiting to get the kinks out before they really start pushing GSM/GPRS. My Treo appears to be on shedule to arrive Wednesday (Feb 27). I will take my Motorola GSM phone SIM and see if I can get the Treo to work on AT&T's network, and report back later.

    I talke to AT&T here in the Seattle area where they have rolled it out. Between the nice gal I talked to there and what I have seen on the various news and what is listed on www.gsmworld.com, I think
    AT&T is a wait and see at this point.

    There GSM service is expensive and there is no One-Rate Plan for it yet and the phones are not TDMA compatible that are available at this time. However, Motorola is apparent coming out with a TDMA/GSM everything phone.... GRPS is my the kilobyte... but voicestream effective charges by the MB via Istream. Circuit Data SWitch should just comeout of the min bucket, but different people have said different things about this .... I think it just depends on who you talk with and how you ask he right questions.

    The Treo, though, is 900/1900. Rumoer is a CDMA version of the Treo that is 1RX compatible will be out at the end of year. In the mean time, I am considering keeping my SprintPhone (I am on a month-moth Free and Clear , getting VoiceStream.... and If I am going to be out of GSM coverage, call forward from VoiceStream to Sprint.....

    VoiceStream's call forwarding simply is deducted from your min bucket for the plan your on.... Sprint dings you for the mins in your plan PLUS an additional 10cent/min charge.

    So, at least I am assured of having working voice phone in most places in the US I go places that are Analog only just enough to want to keep Sprint for the reasons I described.

    But, AT&T, I think once rolled out, mayultimately be the company to go with.

    Just my 2cents worth.

    I want the treo, I want the color treo, I will probably spend way to much money on the 180 only to upgrade to the 270 when it comes out

    I was told by the AT&T rep here in Seattle where GSM is being rolled out and sold as a service
    that the TREO will not currently be supported. When pressed, what she said was they will not support the phone at all if it doesn't work. She suggested that they might lock the sim from non-at&t phones.

    I think AT&T is a wait and see at this point, but I'd fell better about AT&T than VoiceStream....

    I still haven't decided to get a Treo, but I certainly want one.... VoiceStream is what is making me fudge.

    I received this message from Handspring sales:

    The Rep at an actual AT&T Wireless store (Reton near
    South Center for those in the area) that I stopped in,
    and showed me the GPRS enabled Motorola Phone I could actually buy and I got this fancy 4 color brouchure says it
    is in Seattle

    She was suggesting that the AT&T provided SIM would not work in non-AT&T (I don't know how much BS that was), not that the
    Treo (or other non-AT&T phone) would be locked. Sorry, I wasn't
    clear on that in my original statement.

    It was her other comment that I have no reason not to believe:

    What she was clear about is that if I called with a non-AT&T phone, including the Treo, having GSM service problems I would be told the non-purchased AT&T phone would not be supported.

    Plug in 98105 for the zip code when www.attws.com comes up
    and you'll see that AT&T will provide service in Seattle.


    The prices in the brouchure called "AT&T Wireless GSM / GPRS Network: GSM/GPRS Mobile Internet Phone": are as follows (it is basically a regional plan):

    $49.99 for up to 400 Voice Mins, .40cent/min overage, 1MB data included
    $59.99 for up to 600 Voice Mins, .30cent/min overage, 1MB data included
    $79.99 for up to 800 Voice mins, .25cent/min overage, 1MB data included
    $109.99 for up to 1200 Voice mins, 20cent/min overage, 1MB data included
    $159.99 for up to 2000 VOice mins, 15cent/min overage, 1MB data included

    Long Distance is 15cent/min on all above plans.
    Data charge above 1MB is $0.0075/KiloByte on all plans cited above.

    Night and weekend packages are also described for the above
    packages for calls placed within Home Area Coverage.

    Also, according to the Brochure, they give you 30days to
    cancel before having to pay a $150 early termination fee.

    I suspect with AT&T partnering with Cingular, these kinds of prices which are aimed at Business users will be cheaper (
    and of course with less customer service) in Time.

    AT&T, while it has its faults, I think is a better company than Cingular.

    I sure do agree with the last statement, it is the only part of buying the Treo now that bugged me... going back to Cingular/Pac bell. I got rid of (then) pac bell for AT&T a couple of years ago and have not had a single complaint about the switch.

    I'm already looking forward to moving back when possible, although I did have a great Cingular day today... read
