UMTS / 3G
> 3G for Cingular on a K800i
Bookmark topic
Well, I've looked through the forums for a solution to this, but haven't found one yet. Basically, I got a new K800i, unlocked, off the internet. It works perfectly fine for normal GSM use (phone calls, slow data transfer, etc.), but the 3G isn't active at all. I know it isn't a problem with the sim chip (transferred from my old Z520a), as a coworker of mine also has a 3G Cingular phone with the same kind of sim chip, and their 3G is working.
Is this something I need to have activated on my actual account? Or is there some weird setting somewhere deep inside the phone that'll activate it? Or any way to just plain unlock it for my use?

This is not the problem of your account, but the phone. K800i is not capable for 3G frequency in the US. You can find hepful information in the forum.

Cingular those bloody suckers are using 1900/850 for their 3G. The international standard is 2100Mhz. They don't tell you that, because they suck.

As a matter of fact they tell Anyone who bothers to ASK before buying a 3g phone - it's been common knowledge that Cingular will Not be using the international 3g standard and I can see why - they own the 1900mhz frequency and are re-locating all of their basic GSM to 850 so 1900 is open for anything. Why pay another licensing fee to get this? The amount of infrastructure it would require to add 2100mhz is bad enough.
Don't get me wrong - I'm not happy about this, but you can't say that they suck because they don't have 2100 - that was a business decision. They care about their 60+ Million US subscribers, not about other people who MIGHT use 3g when visiting the US. I have known that the 3g here in the US won't work with other international 3g phones since January of 05 - I was still testing the old AT&T 3g service and wanted to get a moto e1000 to work on it - once I called support they told me exactly WHY this won't work.
BetaSword - I'm curious, did you look on Cingular's OWN support forum? This question has been asked AND answered many times before.

You are not the only one that went thru all this bullsh.. The best way to be ahead of then is to buy a quadband that they support but get the original unlocked version so you can do more

Cingular will NOT be using 1900mhz for voice, they're converting all their 1900mhz voice network to 850, so the P990 you have as it is is only usable for 50% of its features in the US (no 3g) and soon it will be very useless on Cingular since it lacks 850mhz. It'll still work as a voice device with GPRS data on T-Mobile, not sure what their plans for 3g are, but last time I read something they didn't have any plans to go 3g in the US. That's why I got a hold of a quad-band k790i so at least I have EDGE service. Sooner or later there will be a multi-band 3g chipset I bet, but that's a long ways away at this point.

Um actually Tervel,
GSM network for ALL of North America USES the GSM 850/1900Mhz for Voice & data. Rogers Wireless, Fido, Cingular & AT&T, WEST ALL do this. The dont own it they own a license to broadcast on those bands. The CRTC (Canada), FCC (United States), Mexico & South America their respective governing wireless bodies I'm not sure of. Tmobile USA is a different piece of the puzzle. They DIDN'T get their licence to broadcast on the GSM 850/1900Mhz bands for DATA (GPRS/EDGE asside - Voice they do but for their upcoming 3G NOT)
This is a REGULATORY decisions not a BUSINESS decision!! Facts my friend FACTS.
For our lanscape 850mhz band is more powerful (just the nature of lower frequencies travelling farther distances & penetrating structures more efficiently than higher frequencies).
TMobile's licence for 1700/2100Mhz will cause issues with manufacturer's

Years ago when people started to talk about 3G the most important word was UMTS - universal mobile telecommunication system. Specialists said that UMTS will stop the situation when one mobile system has too many different frequencies. They promised that UMTS network will use only one frequency in the whole world.
But look where we are now.. 3G (or UMTS as we also speak) is like GSM with several different frequencies.
So even multiband phones like Nokia N73 (GSM 850/900/1800/1900 + 3G 2100) won't work everywhere...
I guess they should make a mobile phone like a radio which can seek and work in different system / frequencies.

Actually some parts of North America are covered by GSM 900 also. For example Cuba uses GSM 900. In Dominican Republic there is GSM 1800 and 1900. In Jamaica GSM 900/1800/1900. In small Saint Lucia you can find even four freguencies: GSM 850, 900, 1800, 1900. Etc. By the way, Greenland (GSM 900) is also part of North America
And in South America GSM 900 and 1800 are well known.
