Td-scdma China Mobile

Hey, China Mobile just went live with their homegrown version of 3g. I was wondering if any of you super smart coders out there if XDA land woudl know if we will eventually be able to download a radio or setting to our TYTN II's that will allow us to use the TD-SCDMA sim cards to access China's 3g network or is it a different chipset?
I've searched all over the internet and I guess i don't know enough about the differences in technology to understand if it will be possible.
If it's not possible I’ll probably end up buying one of the 3g phones that China Mobile has on sale here in Shanghai.
Also what is the best radio to use in china. I know it's all over and I am probably going to get flamed for asking but i everyone seems to have a different opinion and not all the posts include the latest radio's released.
Thanks!

Id love to get an answer for the above question as well. I bought my TyTn II hoping that they would use the same 3G and 3.5G in the future as was available on my TyTn II but it seems it may not be so.
Thanks in advance to all those that respond.

LZ(Chinese word,means #1),td-scdma is available only in china.and no forign phones can work with it

3G Diamond for sale (Canada/US)

Hi guys,
Well, the shop that originally sold me the GSM Diamond has exchanged it to the proper 3G unlocked version.
Do not want to go through the bother with shipping back to Japan and dealing with customs. Besides I pre-ordered my Touch Pro with expansys
Thus, I have a new 3G model up for grabs. I paid 750 Canadian for it. Will let it go for 650 CDN.
Thanks.

This would be 3G on Rogers Network? Are you sure of this?
Has it been opened our used yet?

There is no network associated with this. It should be an HTC Retail version that is 3G capable hardware wise. Weather you choose to use it in a 3G network area is up to yourself.
It would be unopened but to be honest I have asked my friend to open it and make sure that it is the correct model that the shop is exchanging for me. So, in actuality it will be opened but unused. He is just going to make sure it is indeed unlocked and 3G.
The reason for this is when I orginally bought the diamond from this shop before returning to Japan they gave me the Indian GSM model, which they are not exchanging as mentioned.
I guess if it is a huge issue to anyone I can ask him not to open it and go by the specs on the box. Buyers choice. But, I need to know as the new one should be in by Thursday.
thx

Careful potential buyers, there is no Diamond, with any ROM, that currently supports North American 3G bands... Only 900/2100mhz. Does not have the hardware necessary to do so.

Thanks for that. Perhaps the best thing is for me to ship it back to Japan and sell here. Not sure if this can be included in any future radio/rom update/upgrade at this point.
But it is the 3G version but as mentioned about supports 1900/2100 frequencies.
Currently:
HSDPA/WCDMA:
*
Europe/Asia: 900/2100 MHz
*
Up to 384 kbps up-link and 7.2 Mbps down-link speeds

Yeah, didn't wanna be a jerk and get you out of a sale, but people should know what they're buying. I'd ship it back to Japan if I were you, that's probably your best bet (unless someone would rather have EDGE on their Diamond now than 3G on it in a few months).

np,
I would just recommend that anyone thinking about it read the specs on the HTC site for the current model.
thx

I'm gonna keep this thread alive for the next 3 days, then it will be closed and cleaned up!

My Diamond has no Front camera!

What the hell????
I bought one from ebay.
rom version is ASIA WWE.
No front camera.
Why?
I didnt know there were 2 different versions.

Pictures please. Could be fake...

you bought the version without 3G

After doing a little research just now i found this...
My diamond came branded with an Airtel startup logo.
so I searched a bit and found this is a company from india.
now I am guessing the phone came from india.
although the seller did not say.
anyway.
looking on the offical HTC websites and navigating different countries you can see that most, if not all, have pictures of the actual phone with the front camera.
except for.... INDIA...
http://www.htc.com/in/product.aspx?id=48110
look on the official specs...
Camera 3.2 megapixel color camera with auto focus
it doesn't even mention the front camera as in other countries.
and the pictures don't show the front camera either.
now thats something...
why? no clue....
but beware that this can happen with you too...
I guess I will have to live frontcameraless ...

check this and the comments too:
http://www.engadgetmobile.com/2008/05/23/india-picks-up-htc-touch-diamond-3g-not-included/
apparently it has no 3g.. petroOMG is right..
and also it seems that the phone is cheaper in india becoz of this.
I was wondering if it could be a firmware lock only, but I guess the price difference answers my question...
I have modded my phone ... before noticing this..
Upgraded the Radio Version and Firmware to a cooked one..
Everything is working fine.. reception is normal..
I cannot test 3g though as my carrier doesn't support it at the moment.
oh welll.. if you gona think about it it is no big deal for me...
here in my city in brazil 3G is still being implemented and only some areas of the city has coverage with lots of dropouts... everything "beta" at the moment.
At least its not a fake...

Or just put it back on eBay, sell it on and then get the one you want?
Up to you. Depends if you can live without the front facing camera or not.
I occasionally use it so find it pretty useful but i bet most of the Diamond users out there don't bother with it.

the reason is that the phone is made for India,wich country doesn;t have a 3g network.There is no reason for secondary camera for 3g phone calls

Hello ppl....i,m putting this information in block letters because i want everyone to see......the phone makers are taking away front camera option we cant use front camerato take anymore pictures....only when we make video calls can the fron cam be use.....the same with my nokia 6600 slide......spread the word

I don't think it's a "no 3g" thing..
the US 3g doesn't have one either. I wonder if it has to do with the market instead. (regulations, licensing, etc.)

maybe in regions where video-calls are not supported, the devices are coming without front camera?

Different areas differnent Diamond
North American Version (USA) has 1350 mh battery and dont have front camera and 3G for american bands, mine is this.
Argentina version (Personal Opereator) has the same bands that the american (is ok for us), has 1350 mh BATTERY (as the north america version) and front camera.
Depends the country and the operator.
Sorry for my english

True, this version is different from Airtel, 3G support, but if this is not for video call, come in the box specifications.
The chip is not MSM7206A is MSM7201A
http://www.htc.com/us/product.aspx?id=60040
Version US
http://www.htc.com/europe/product/touchdiamond/specification.html
And this is European version.

I have one that odesnt have the front camera, does that mean that i can't get 3G coverage in areas around me that have it? I have a radio version that supports 3G but if the phone itself doesnt have 3G capability then ill send it back...

I also bought the same from ebaybut onlt for 175$ and it has no front camera, although, i'm happy to have a diamond on the price of carbon!
Why you guys are worried?
My fone is a 3G handset, and i never make a video call, so, why i afraid of not having a cheap VGA front cam?
If you guys too, never made a video call and then also reading this post!
Shame on You!!!!
Don't worry n Be happy!!!!

HTC Diamond World or US? Need Help ASAP!

Right now I have a choice between original HTC Diamond or the US version but I am not sure which one to pick. Can anyone please shed some light on this? Thank you in advance!

it would help if you were to mention where you live (US vs. Europe) and travel to, and other things factoring into your decision. if you're in the US (e.g., live here) go with the US version because it has the correct 3G radio; high-speed internet access on your phone AND 850 band which provides better signal..

Sorry, I live in US and on T-Mobile network.

Main difference between the EU and US models lies in the 3G/HSDPA data connections. While serious doubts/uncertainties on the use of EU model for 3G on T-Mobile (only 26 cities in the US so far) have been raised (details can be found in this thread), the US model will allow you to use the 3G/HSDPA data connection should you decide to switch to AT&T in the future. Second, the EU model has a front camera for video conferencing, but I was told neither T-Mobile nor AT&T would make this option available to their phone customers at this time. There are software available through Wifi for video conferencing as I learned from this thread, and you would need the EU model to do it if it works (I haven't tried). Google Maps, third, is not installed in the EU model, but there is a CAB file to be downloaded from this thread or the google website. Price wise, at last, the US model is a little cheaper than the EU model by $10-$20 USD (may due to the lack of the front camera?). There have been reports in this thread about yellow/green/wash-out background in the US model. This may be something you want to check closely if you want to consider the US model.

I read some other thread here which points out that the Euro version has the yellow spots and yellow tint problem, not the US version.

good clarification on the 3G network; T-Mobile uses, I believe, the 1700 3G band in the US and att uses the 850/1900 3G band. also, if you weren't aware, the US version of the Diamond is available at Best Buy Mobile, typically located in Best Buy stoes.

Then probably yellow tints/stripes are found for both models:http://forum.xda-developers.com/showthread.php?t=426319&page=10, which is for the US 3G Diamond.. sigh
@cortez.i: Thank you for confirming the complicated 3G issues

The US version is also more easily returned and exchanged by just going into a Best Buy and it will be better covered under the warranty from HTC. HTC is not pleased that companies like Expansys sell Euro HTC phones to customers in the US and says it won't fully cover those phones. You can't use either model on 3G on T-Mobile USA, so for you the main difference would be the warranty.

Not 100% but think there's only 2... India, European, UK etc all have same model number then there's the Chinese version.... by the looks of ad and then not replying I'd assume it's the Chinese version.

so you think that 1 is ok? or skip it??

if it is chinese model any good or skip it?

I bought the Realme X2 Pro 256GB/12GB supposedly Global/EU version, live in Orange County, CA, and on Android 10 C24 update using the T-Mobile network. When i go to Settings->About Phone under 'Model' i see "RMX1931".
I just updated to C24 and same problems as posted here: https://forum.xda-developers.com/realme-x2-pro/help/how-to-to-android-9-colouros-6-android-t4071317
and my rant/venting here: https://forum.xda-developers.com/realme-x2-pro/help/downgrade-realme-ui-to-color-os-realme-t4080299
The thing with this phone is that nothing is clear on what is working or what should be working with T-Mobile network, in my area at least. I can tell you though that besides the bugs/issues on the links above, this also does not work with this phone in my area using T-Mobile:
-No VoLTE
-No Wifi Calling
-No 4g while on a call(could be related with no VoLTE due to the missing bands on the phone)
Also on the T-Mobile network, on my previous phone, HTC 10 unlocked global version, i had wifi calling and 4g when on a call working - and i find that ridiculous that on a 5+year old model phone these both things worked and on a "high spec" 2019 model phone like the Realme X2 Pro none of those things are working and yes i know the X2 pro is meant to be used in other parts of the world, like china and india but still, when you sell a "global" phone(not priced cheap @ $500 imho) it should have all those 'basic' functions, like wifi calling, at the minimum! i bought at my own risk i know, so im paying the price now:crying::crying:
if you are willing to switch providers like maybe Verizon or ATT maybe you can have better luck with this phone with all the "basic" functionalities.
i was about 75% sure of getting rid of this phone and now im like 99% sure of getting rid of it. You interested? lol
btw, i bought this exact one from this seller: https://www.ebay.com/itm/Realme-X2-...hash=item34211a23a8:m:mS2Nl-L-Htood4wYaECLYCw
dam ebay!!

ok they finaly said its india version is that any good or skip it?

i bought X2 pro phone about 1 month ago and if i was going to do this all over again i would i would go for the Xiaomi: https://www.ebay.com/itm/Xiaomi-Mi-...hash=item341aea54d9:m:mH_wyne-_SXAdmrXP7eck1g
before i bought anything it was between the X2 Pro and the Xiaomi, same price, but i went for the X2 Pro because of the faster snapdragon 855+ processor and more ram. I dont really care for the crazy 108MP camera(s). But if you do your research for the Xiaomi, i believe VoLTE, wifi calling, and 4g while on call, all work with the Xiaomi on the T-Mobile network.
Good luck buddy!

anyone who bought the 12 gig model that is the GOOD model for usa tmobile/att etc where did you get it? if you can link me to it thanks

anyone order this exact 1 from this seller? and if so what model is it? https://www.ebay.com/itm/Realme-X2-P...r=442520443345

If your not bothered about the camera which is the main selling point of the Xiaomi mi note 10 then the only decent point is the large battery... everything else is worse then the X2 Pro... Unfortunate that your having issues with networks as I have WiFi calling etc on my European version using ID sim which is a virtual network on three UK and working perfectly.
EDIT: Just read your rant and the other thread and can honestly say I have no issues with speaker being to loud during a call and zero issues with mic. I didn't have them on Color OS and I've been running the Realms UI c23 from the India site since 30th without the issues... installed c24 from UK site today and I've had nearly 3h calls today without any loud or mic issues.

LIke i said on my other rant, maybe i got a bad one from a bad batch:crying: which sucks because 30day policy expired from the ebay seller and i dont think i can return(ill double check anyways). And yes, the Xiaomi has larger battery also and yes i would of have ignored the slower porcessor etc. if it meant "normal" functionality on the phone with VoLTE, wifi calling, etc. all functioning - i would prefer a working phone than dumb issues and missing basic functionalities etc. MY2C i guess.
But like i said before, when i got the phone new with Color OS 6 Android 9, the earpiece/handset during voice calls volume was working "ok" at a tolerable level and i could be fine with the mic issue, having to enable speaker mode and then disable during call, i wouldnt have mind that at all. That is the reason why i would like to go back to Android 9 but i have no idea how - or im too dumb to do it ....still doing research of how i can go back.

ok got phone Fleabay SWORE it was GSM Model only but on side of box says GSM:850/900/1800 WCDMA1/2/3/4/5/6//8/19 LTE TDD BANDS 34/38/39/30/41 LTE FDD 1/2/3/4/5/7/8/12/17/18/19/20/26/28 model number rbs9x225in..... so what region etc is that?
