Hello.
I have got a nokia 6630 and when i go to network settings there is the option for network mode dual or network mode GSM. Can anyone explain me what is the difference? Both seam to work with my operator so which one shall i choose?
Thanks
Here are some definitions of what it could posibly be. taken from phonescoop.com
1. A phone that supports both analog (AMPS) and a digital technology, such as CDMA or TDMA. The digital mode could operate in either the 800/850 MHz frequency
band or the 1900 band.
2. A phone that supports both 2G and 3G technologies, such as a GSM/UMTS phone.
NOTE: This definition applies to the U.S. and Canada, and may not be accurate for other countries.
I would actually suggest talking to nokia or reading the manual. It's a really good question and I hope you will share the answer. I would love to know my self. The only GSM/Analog hybrid that I know of was a gate phone used in the us that would support both analog and GSM freequencys. This phone is no longer made.
Thanks for the definitions.
I will try and do some research as well and if i find something i will post it here.
But the interesting thing is that my phone work with both gsm and dual mode and i can't tell any obvious difference.

I asked this question in yahoo answers and here is the answer i got.
I don't know how correct it is and i might get more answers.
The Nokia 6630 is designed to work on both GSM and WCDMA networks. If your carrier does not support both of these then there would be likely no change in
performance since you would always be using GSM. If you were to travel to areas where the WCDMA signal is dominant then having the dual-network functionality
would come in handy.

I did a little research and you are correct. WCDMA is new and I didn't realize that the 6630 was a fairly new phone. That is why it will work in both modes. The dual mode will kick in to the wcdma mode if you are on a network supporting it.
Here is some more info about WCDMA which might help you understand it better. Sounds like the future of GSM.
(Wideband Code Division Multiple Access)
Wideband CDMA is a third-generation (3G) wireless standard which utilizes one 5 MHz channel for both voice and data, initially offering data speeds up to
384 Kbps.
WCDMA is also referred to as UMTS - the two terms have become interchangeable.
WCDMA is the 3G standard that most GSM carriers are moving to. Parts of the WCDMA standard are based on GSM technology. WCDMA networks are designed to integrate
with GSM networks at certain levels. Most WCDMA phones include GSM as well, for backward compatibility.
WCDMA borrows certain technology ideas from CDMA, as the name implies, but is in fact very different and incompatible with phones and networks using "CDMA"
technology.
In Europe and Asia, WCDMA is being deployed in the all-new 2100 MHz frequency band. In North America, WCDMA is being deployed in the existing 1900 MHz (PCS)
and 850 MHz (cellular) bands.
Thanks a lot for the information. Very interesting.
