No, this is another TDMA phone like in your other post. Check out the link above for phonsecoop.com, it's a really cool site. Instead of coming here to ask if a phone is GSM, IDEN, TDMA, or CDMA you can go there and type the model number into their search. The first line under Specifications will tell you what "mode" the phone uses.
You never replied to my question in the other thread? What service do you plan to use the phone with? It has to be unlocked if it's not branded to the carrier, and IDEN SIM cards won't work in GSM phones, GSM SIMs won't work in IDEN phones.
Make sure you know what is compatible with your service!

Hey Brad.. thanks for being an awesome resource.
I will be changing to Cellular One because Cingular is forcing me off since I roam more than 50% of the time. Cingular is sending me the code to unlock my phone. I'll check out the site you gave me. But can you please tell me which systems use sim and which dont? Then I can understand the info on the site. Thanks again.
PS the spanish comment wasnt about your thread it was on someone elses

Hmm, I don't know much about Cellular One but when I looked them up on google it said they are CDMA or TDMA. I didn't know any major service providers would still activate a TDMA phone, maybe you should call and ask them if they will instead of taking my word for it.
CDMA networks like Cellular One, Verizon, Sprint, and Alltel do not use a SIM card, the phone is hardwired for the provider and activated by ESN (electronic serial number).
GSM networks like Cingular and T-Mobile use a GSM SIM card, and iDEN networks like Nextel and SouthernLINC use iDEN SIM cards. Note that GSM and iDEN are not compatible with each other.
Hope this answers your question, I'm still half asleep today

One more note about TDMA vs CDMA, you will get better service with the CDMA phones, as I said before, TDMA is obsolete and is slowly being phased out. If you live or travel through rural areas, CDMA is probably the best choice for you, as CDMA towers can transmit further than GSM towers and they generally have better rural coverage.
The great advantage of GSM phones is being able to store all your contacts on the SIM and swap phones without losing all that data. They are also compatible with GSM systems worldwide as long as they have at least one of the international bands (900/1800mhz, whereas GSM networks in the USA use 850/1900mhz). I like my CDMA coverage through Sprint, it works great in rural SW Georgia where I have family.

well I went down to the local provider and they tried to tell me that I couldn't switch sim cards. But I dont believe them because they lose the sell of the phone (the cheapest phone they have is $100 with a one year contract!) however they gave me a brochure and on the cover it says "national gsm plans" plus my dad has a cellular one phone for work and it has a sim card. So I'm guessing it will work if I can just find a sim card grr grr. BTW which part of Jacksonville are you in? When I'm there I stay out at the beaches on san pablo.
PS.. so does this mean I should find a phone from that site that says gsm?

Okay, CellularOne is confusing to me. Every time I put in a different zip code, they forward me to a different site, like T-Mobile or Alltel. What is your zip code? It says on their site they are a "network of over 35 carriers" which tells me they might use GSM in some areas and CDMA in others but I'm not sure. Their web site is not helping me find the answer to my question, at least not until I find a zip code they directly service.
I live on the westside of jacksonville (yeah redneckville but the rent is cheap). I have an aunt that lives in Ponte Vedra Beach, that's close to where you stay.

I live right now in 99840 and also I'll need it while I'm in Jax. They say I can use it in Jax and roam off Cingular towers. Ponte Verda Beach.. umm I think thats where Christ the Redeemer church is. They have a good saturday night service. It's hard when I'm in Jax cuz I dont have a car so I have to bum rides everywhere

Okay, apparently your Cellular One service is GSM. I don't understand why they have a whole long page all about their innovative CDMA technology, that's why I'm so confused with them! If your Cellular One phone is going to be roaming on Cingular, then it's GSM and no matter what they tell you, any unlocked phone should work with your SIM.
One problem you might come across is the unlocked phone probably won't be able to access any text messaging or web services, it'll basically be 'just a phone' unless you can get CellularOne to configure the settings for you.
