Hey guys,
i would like to ask if there is any possibility to use some uni smartwatch band? I mean, I am looking for band that would work with, lets say, two different brand smartwatches. I know that there is a lot of companies that makes watches with 22mm band, which should in theory work with other smartwatches with 22mm band. But are these band really similar? Or if it is possible to swap one band from one smartwatches to another.
Thank you

Hi, can I change touch dual the GSM from Tri-band to Quad-band,
for the better reception in USA.
I know the touch can do that, Thank
Now that its going to be available in the US with quad band, does it mean tri band niki can be changed to quad band?

I would like to know this too
It could be possible, but the RF chipset could be totally different on the two models.
There wouldn't be much of a reason for HTC to restrict the current tri band duals with the way the various operators have deals with other overseas operators.

You would think they would have designed, developed the radio chip long ago, and the new edition would only contain software changes to the OS, and Hardware soft updates
--bump--
I too would like to know if this is possible. The best buy website has a touch dual listed with 850. I called their customer support and they couldn't give me any information on release date or even a model number. Will the US version of the dual have 850? I want to know if I can get this $500 phone to work here (area code 318 with ATT) on just the 1900 band or do I need the 850 band for better reception. Any advice would be helpful. Thanks in advance.

Any luck? I would like to upgrade to the quad band
theres only one version of the dual that is quad band and that is the US version being sold by BEST BUY.
Thanks for the reply I figured I was out of luck, so I ordered the us version yesterday.
Bought the triband Dual but, soon figured out that it doesnt work well in the states.
I thought I would give it a go.
Thanks
Was working on 850MHZ than....
My HTC touch was working on 850 MHZ than I had a tech at my provider's, setting up my internet.
Since that moment it does not work anymore:
Getting the signal but not able to make calls or receive calls.
The guy tried to fix it. It worked for a couple of calls and than stopped working.
Back to the tech, he told me it s because of the 850mhz on which they operate.
He said that even if it was working fine, it wasn't meant for their network (850 MHZ).
Should I believe him?
(the phone works fine with 1900MHZ band from another company)
How can I fix this?
wish there was a radio upgrade like the latest for the diamond that enabled the 850 band
Anyone who understands this "spectrum" 3g AT&T Tmob issue more than I.... I have a ?
Okay so here it goes....
WTF!!!!!!!!!!!???
So I've been reading all day to understand this and I do get how we ended up screwed on 3g from the rest of the world
Tmob is on "aws" which is sort of a halfway between 2100/1900 of Europe at 2100/1700
AT&T is on 1900/850 or 850... I couldn't find a straight answer on that.
Now everyone says this is "hardware" in the phone that dictates this issue. I've been researching (this is where I could use your help) and I'm missing something. Nexus one is using Qualcomm Snapdragon™ 3G QSD8250.... This AMAZING chip is not only the processor but the 3g chipset as well... (correct?) Yet this same chip is in the LG expo and the LG expo has 850/1900/2100 for it's 3g.
It would seem to me... (a simple man) that Qualcomm would NOT produce separate chips but would use some firmware/software to let the chip determine which frequencies to use. Otherwise they would have to stamp out more than one chip instead of just having one factory.
The other major issue I see is antenna length is a physical characteristic based on the radio wave you are trying to receive/send. So that may have to change too but that's more about being optimum than impossible.
Not that anyone has the cash for this but what would stop someone with REALLY amazing soldering skills from switching the two supposedly identical chipsets? Would that extremely silly idea work?
Just a thought that I thought a few people on this forum may understand more than I do.
First, the radio ROM should be the one to dictate what frequencies are supported if the radio chip can support multiple frequencies, which it does. There is a soft radio chip from Samsung (I think it's Samsung) that can be reprogrammed to change which carrier it's supporting, but I haven't read of it being used yet. I believe that's the future, but currently you get a chip that almost universally supports European 3G and quad-band GSM w/EDGE out of the box, and then *one* set of US/Canadian frequencies. That's it.
WIND (new Canadian carrier) is using the same AWS spectrum as T-Mobile US is, so that should give more "pull" for more AWS support in future handsets, but with T-Mobile moving toward a "dumb pipe" arrangement (no annoying a la carte options, no music services, no stupid "extras" to pay for, just voice/data/text plans) the hope is more devices will be available in the open market that will just work on T-Mobile and support whatever you're paying for. Since your ISP is just "there" and "supports" (ish) whatever you're using, the hope is T-Mobile US will set the trend for that behavior here, and WIND might be going the same way in Canada, and FINALLY bring this mentality to North America.
If that works out, expect to see more soft radio chips and ROMs to come out with these handsets so they can be "flipped" from network to network and still support all the data and voice options. If it doesn't (I think it will to some degree), then expect the long and annoying tradition of vertically integrated handset and carrier support where the handset has to be "made" to support whatever options the carrier chooses (for compatibility and being as cheap as possible to make) and not have full, cross network support for devices.
Softchips aren't common and won't be. You could probably swap the chips directly, but it's going to cause issues.
T-Mobile uses AWS, which is 1700/2100 for down/up stream. It's considered GSM band 4, which is different from Europe, who uses a 900 band and a 2100 band, both of those are full up/downloads on close bands, so some places use 900, some use 2100, some offer both. It's a bit different. The Nexus One supposed 900/AWS/2100, meaning it's 100% Europe and T-Mobile compatible. We're seeing more and more of these chips since it's significantly simpler than making Euro + AT&T chips.
Motorola is developing a chip with AWS + 850/1900, meaning sometime next year, we should be seeing truly "USA" model cell phones, which will support any US GSM carrier. Euro+USA full could come eventually, but the addition of AWS means it'd take a 5-band chip instead of Quad band like EDGE.
T-Mobile 3G Upgrade
FCC cleared radio frequencies about 3 years ago, T-Mobile bid on the majority of them and used it to upgrade its network.
Much lulz were had.
Here is a List of UMTS Networks. Pretty much all of Europe uses 2100.
I'll do more research as to WHY, but most carriers opt for certain frequencies because of hardware compatibility and cost effectiveness for when they were upgrading.
That link makes it appear that AT&T is worthless outside of NA, but that's untrue (AT&T has, for the most part coverage worldwide, or so I think...) so I'll do some more research on my lunch break.

ATT has some coverage (edge once again) everywhere, some places in canada and australia have 1900, but ATT for the most part is using a freq that's not very universal
The issue is the amplifier module.
I have the Rogers G1 running on AT&T 3G. The radio firmware/software is identicle to the T-Mobile/ADP1 phone.
They did a tear down of the G1's and they both use physically different amplifier part numbers. It's not a part from Qualcomm and has nothing to do with their chipsets. Their chipsets do indeed support AT&T's 3G frequencies, if paired with a compatible amplifier.
Now if someone tears down the Nexus One, and gets the part number for the amplifier, and that amplifier can do AT&T frequencies, it may just be an issue of hacking the radio somehow to enable it.
It's quite possible the amplifier on the Nexus One can handle AT&T 3G, but they didn't bother to "certify" it with the FCC because T-Mobile is te launch parter and AT&T is sucking Apples teet.
One can only wait and see. I'm betting it simple doesn't have the correct amplifier for AT&T.
There are amplifiers that work on all frequencies. Why they don't spend the extra dollar or whatever is beyond me. They are literally THAT cheap.

Or sell two (or more) versions of the phone?
850/1900/2100
900/1900/2100
1700/2100
I would guess ... idiocy.
Even more idiotic ... phone manufacturers building phones with NAM 3G frequencies ... but not selling them.
It seems the Nexus One at least has the hardware to support AT&T 3G, see my post here.

Hi there,
I would like to buy a smart watch phone. I need GPS and 3G. But it seems most watches, made in China, only have WCDMA 2100 band. I found this one:
http://www.dxsoul.com/product/kiccy...4-screen-wi-fi-4gb-rom-901363988#.VNZmf53F8k2
I have never heard of this brand. The design of the watch shows that it is probably a clone of Omate Truesmart. But Truesmart only has the 2100 band. This one claims it has WCDMA 850/1900/2100. If what it claims is true, I am supposed to be able to get 3G speed with an AT&T data SIM or a T-Mobile SIM (I am in a refarmed 1900 band area), right?
Thanks. Any thoughts? I do not want to buy a product that does not support 3G. This product has a newer CPU, which is attractive.
It's a simple dream: to leave my phone at home and go running with my smartwatch streaming music. It seems so basic, yet few watches are capable of doing this because it requires 3G connectivity.
AT&T uses UMTS frequency bands 850 and 1900 while T-Mobile uses 1900. To my knowledge, there are only four watches that have both bands needed for 3G connectivity in the US:
LG Urbane 2 LTE
Samsung Gear S
Samsung Gear S2
Doogee S1
Do you know of any others? Please add it to this list.
I'd be careful when it comes to the Doogee S1. It kind of says a lot when even their official page has the specs wrong.
You also need to keep in mind that this is an international forum, so for a lot of people 850 and 1900 are not a requirement.
A few more...

US 3G options are very limited, but you can add the Neptune Pine, and Omate Truesmart. Suppossedly the new K9 Chinese smartwatch supports 3G on the AT&T 850Mhz band. Will not support 3G on T-Mobile since it only supports 2100Mhz 3G.

850MHz coverage is limited, AT&T primarily uses 1900MHz. As far as the TS, the original U.S. model hasn't been available for some time and all the new ones are 2100MHz only.
That's one of the reasons why I've keep my TS for so long. All the work you've done on this device plus the 3G. I wonder why the Chinese smartwatch manufactures won't include the US 3g bands. I would think the market is pretty big here in the US...
Hi all,
I am considering buying an OP5 from Dubai, but I live in Europe (Switzerland).
Does anybody know if the specs vary around regions? Or is it safe to assume that 4G/4G+ will work (including band 20 etc.)?
Thanks

Please search. I'm sure you can easily find what your carriers Lte bands are and then research what's op5 bands are supported
I know what the bands for my carrier are and I can find the specs for OP5 on the Oneplus website. It appears that there are no differences in the hardware across regions but I wanted to confirm that. I know other brands (like Xiaomi) differentiate the hardware depending on the region where the phone is sold.
OP5 now supports 32 bands, all on same worldwide phone.
