    OK, so now most of the 650 threads are shifting to GSM related topics. I am a Sprint CDMA user and left GSM years ago because they didn't have the 3G network. Now I guess the GSM providers have some sort of digital network that costs $0.10 per kilobyte or in some cases $30 unlimited or more.

    Whereas the 3G is still only $10 per month more for unlimited on the any Sprint phone. Since the 650 has BT its the phone for me as it is the ONLY Sprint phone (except the crummy T608 that I returned 3 times) that has BT and I want it specifically for reverse DUNs.

    So the question, why would anyone want the GSM service at the much higher cost? I truly do not understand. Please sell me.

    Functionally, the only major difference is the ability to use the GSM in other countries if that matters to you. The GSM is also has slightly longer battery life, but I have yet to go through a day with my Sprint 650 without having ample battery charge left.

    I would suggest going for the best plan, which right now happens to be Sprint. I don't see any advantage to going with GSM outside of international usability.

    Perhaps they need a GSM world phone. The cost for Cingular's unlimited is high compared to Sprint, but maybe they don't send a nasty letter to thier customers who use it heavily. Although I have never been sent a letter by Sprint but some guys I work with have gotten the "letter". But a deal is a deal, unlimited means no limit they shouldn't complain or maybe they should price it correctly. I am on Sprint now but have been thinking of jumping ship but I'd pay about $150 a month for what I get from Sprint for about $67 from my 4 year old plan.

    I agree, I dont plan on using my phone internationally or see a big battery difference so I stuck with the Sprint Treo. Sprint has better plans for me and I never really had much troubles with sprint for the past 3 years. Im a big fan of the 7pm night night time which saves me a lot of money.

    This is what I thought, and is it easily used outside the country or do you have to still pay $1 per minute to use it outside of the country?

    It is hard to believe the recent flurry of hundreds of GSM posts just to use it out of the country. There must be another reason. Do all these people travel that much?

    another reason for going gsm is the ability to pop your gsm card into another gsm phone and instantly have your contacts/phone number transferred to that phone... this is mainly for people who have a 'large phone that does everything' and a 'small phone you like to carry out on the weekends'
    Ever wonder if those FreeIPOD / FreeMiniMac scam sites work? Well, I found out Have a look at the results:

    For me, I think CDMA (Sprint) is better. This is because I find myself off of the major interstates and outside of major cities. CDMA is much stronger in those areas than GSM. It's sorta like the old Beta VCR's vs. VHS. Beta's were better, but the VHS tapes were much more widespread causing most people to choose VHS even though it had inferior performance compared to Beta.

    from reading threads from different forums it seems Sprint Treos are getting faster data speeds. I'm on Cingular and haven't found a good EDGE area yet.. Maybe cuz I have to share towers with 46 million people..

    I actually was considering terminating my Sprint contract, eBaying my Sprint Treo 650 and getting a Cingular GSM 650. But now, after considering it, I've decided against it, for the following reasons.

    1. I don't travel internationally. Fact is, I don't even have a passport, though I probably should get one soon, just in case. And if I did travel internationall, I would probaly NOT bring my Treo 650 with me for fear of it being stolen overseas, and would opt instead for a cheap GSM handset and a rpepaid SIM. That said, the US coverage is just fine under Sprint.

    2. The pricing plans on Sprint are better.

    3. EDGE might be slightly faster in theory and under perfect, ideal conditions, but realistically, EDGE has the same performance as CDMA 1x in real world conditions, and sometimes, CDMA slightly beats out EDGE in the field.

    4. Capacity and performance. GSM might be the more widely used standard, but that doesn't make it the better standard from a technical standpoint. See http://tk.com/wireless/800cell.html for a comparison. The gist: CDMA as less of a capacity crunch.

    So, I'm sticking with Sprint for now. There IS the GSM advantage where having a GSM unit means I could swap phones out easily, but I'm not one to swap phones.

    I guess that I still do not see a substantially good reason to go with GSM.

    I switched from GSM to CDMA for the penetration capabilities. My GSM comrades can't get their units to work inside most of our buildings, but CDMA works like a champ. Also, if I ever get stuck in an elevator, I decided I would rather make a phone call from my phone than to use my phone to pound on the door, I found when I had GSM I would loose signal/calls in elevators . I didn't like that feeling.

    I'm trying out a GSM phone with Cingular for the sole purpose of being able to swap SIM cards. I don't wanna take a $699 phone with me while jogging, or hiking, or even working in the backyard.

    I know [depending on where you live] EDGE is the same as CDMA 1xrtt, or slower. Also, the claim of simultaneous data and voice turned out not to be entirely true.
    So, the only attractive feature for me is SIM swapping

    A big advantage for GSM Treo users is data roaming. With Sprint, you can roam voice on other CMDA carriers, but you can't roam data. GSM is completely interoperable, so your voice AND data will work virtually wherever GSM service exists.

    If you haven't taken a look at a Cingular coverage map lately, you probably should. Their coverage is getting pretty good. There's still more CDMA in this country, but GSM is catching up.

    Here is something that might matter - Coverage. Why does no one think that their local coverage is important? All carriers are not equal in all markets. Everyone always acts like just becuase they have good coverage in their house or office, that that carrier has good coverage in everyone's home or office? GSM has the largest share of the world market by far, that means more *(hopefully better / cooler) mobiles, SIM - changing phones WITh your phone book included is a snap, Cingular is the largest US carrier with the most coverage nationwide. Those are just a few examples.

    Sorry I am just tired of people passing off poor info as fact. CDMA might be better where you describe in your area, but don't assume it everywhere else. Also are you talking about analog roaming on your Sprint phone? Of highway coverage is great in many areas on GSM - maybe just not where you live. All major areas should be covered by GSM.

    This info is not correct either. GSM, TDMA, Analog, CDMA - none of these technologies has some sort of special in building coverage advantage. In building penatration is effected most by spectrum 850Mhz can go through walls and matterial like that better than 1900Mhz can, it's a fact. Power setting on the local cell sites also effect building coverage etc...

    I have seen this said before, and I am not sure if it is true, but it is probably close anyway. Honestly though, who cares if there is more CDMA in this country? If so, it can't be by much, it isn't as if there is a HUGE difference. There is more GSM coverage on Cingular though, than any other carrier in the US. Whatever, just wanted to make that point too.

    scaredpoet - care to explain to us what in that link leads you to believe CDMA has less of a capacity crunch? Different technologies are used differently, so a CDMA network is not even designed the same way a GSM network is. Capacity is part of the system design and any well designed system has enough capacity, simple as that. Also I would like to point out that page you link to is only talking about 850Mhz cellular and makes no mention of PCS at all. Nor does it mention the actual use of the technologies, simple channel, channel size, number of users per freq. (which on GSM also looked to be wrong - 24? Where did that number come from? Anyone? I only know of a max of 8 -16 per channel), etc.

    Here we go again -- why do you people reply to these "which is better" threads -- they never go anywhere.


    Here's the end all answer:

    Who has better coverage WHERE YOU PLAN TO USE YOUR PHONE. I dont care if they have 93 thousand Sprint towers in Alaska, or that all Cingular phones have a constant 9 bars of antenna anywhere in Georgia. I'm not making calls from either of those places.

    Then factor in these main simple differences..

    GSM -- ability to swap sims into different phones and option to use worldwide
    CDMA -- cheaper data plans (sprint) and faster in most places

    Done... There is no answer to which is better, it depends on your area, your habits, etc.


    I really like the idea of swaping sims and changing phones easily whenever I want, but with a discount I get thru work, I get 23% off my monthly bill with Sprint and coverage is good here, so thats that.

    All that matters is that you have good coverage where it matters to you. GSM may have the largest share of the world market, but that is irrelevant if you can't get a signal in your home or office

    I don't know if holds up technically, but my experience is in line with what mrcpu1 said. My Sprint Treo 650 doesn't seem to have a problem in elevators where my old GSM Treo did. It could just be that the CDMA towers are closer, but either way it's working better for me.

    It might be that the CDMA 650 is more sensitive than the 600. I had a Sprint 600 and couldn't call inside my condo elevator. Got the Sprint 650 and it passed the elevator test. It's the first phone I've had that worked in that elevator. Others in my building on the evelator are often surprised I could use it so it appears the CDMA 650 stands out.

    I am pretty sure that is exactly what I was trying to say. People think just because carrier A is great for them and carrier sucks for them that is it the same everywhere. Not so.

    As I said, no it doesn't hold up technically. In my office I get full bars on GSM in the elevator. What does that prove? Nothing. I have a site right across the street and it is 1900Mhz... says nothing about one carrier being better than another. Now if you want to talk about best coverage in that specific elevator shaft, well maybe we could pick a winner...

    That is good news for you then, but it has absolutely nothing to do with CDMA or GSM. As you said, there probably just happens to be a Sprint tower that's located closer to that particular building than a GSM tower.

    Maybe you should read before you attack, sir. I said the coverage is better in areas that are NOT MAJOR AREAS. No, I am not talking about analog roaming. The 650 doesn't support that. I am talking CDMA vs. GSM period. GSM is getting better, but is not anywhere near the coverage of CDMA. When I used my VZW 7135 in these rural areas, it rarely accessed an analog cell. It stayed on CDMA digital nearly all of the time. When it did switch, it would be only for a few seconds. So, before you start condemning other info as bad, maybe you ought to check your own facts first.
