[Q] How to enable UMTS 2100MHz on HTC HD7S T9295 (AT&T)? - HD7 Q&A, Help & Troubleshooting

Hello everyone!
I bought a HTC HD7S (AT&T) for use in Brazil, but my carrier only has 3G on the 2100MHz frequency.
I saw elsewhere that there are versions of this mobile working in 3G 850/1900/2100 and only 3G 850/1900 (unfortunately, mine/AT&T).
Is there any way to make my phone connect also on 2100MHz?
This is my first Windows Phone, and for me is a novelty. I never had problems like this with an iPhone.
Thanks!

you can't, search for why

850/2100 3G Diamond on Rogers CA?

I haven't found any answers so I've decided to "ask the audience".
To my understanding the Rogers Canada network uses 850/1900 for it's 3G primarily 850. Is this true?
I haven't found a mention of a North American release date for the GSM Diamond. Anyone know the date? I don't expect it till around Christmas.
I'm looking at an Australian Diamond that uses the 850/2100 bands for 3G. Will the support of the 850 band be enough to function on the Rogers network or does the phone have to support both bands for 3G to function on the network?
only gsm 850 works on my diamond. i think its 1900 for 3g
I have an European Diamond which works on the rogers network but I get GSM/EDGE but to my horror no 3G
Looking around only on a few sites can I find any mention of what works and what doesn't the closest information I could find is from this link:

NextG phones are 850/2100 capable, so you'll be right on most 3G networks...

and they go back and forth so I'm not sure what to believe and I don't think I want to buy another Diamond just to find it won't work either.
http://www.geekzone.co.nz/Jama/585 has some interesting comments as well but I'm not sure what to believe.
Can anyone confirm or deny and of this?
The question is will a Australian phone with the 850/2100 3G radio function on the Roger network?

I have the Australian version (850/2100 MHz) and it supports the Telstra 3G Network. Can't see why it wouldn't work on other 850/2100 MHz 3G network.
To my understanding the Canadian Rogers network is a 850/1900 network.
Does the phone need to support both bands or will one suffice?
Rogers Diamond
I had an EU/Asia Diam and I never manage to get 3G connection. Sold the phone and bought a Rogers branded diam and by default I see 3G connection all the time on the top network status. But now I'm thinking of going back to an EU/Asia version unless I can flash my Rogers branded diam with a better ROM.

Touch Diamond US 3G with t-mobile

Hey guys i just recently bought a HTC Touch Diamond unlocked US version and was wondering is there a way i can get the 3G to work? i know the T-Mobile's 3G network is still under construction but the new HTC Dream seems to have access to the 3G with T-Mobile. I heard T-mobile uses the 1700mhz and 2100mhz 3G bands, And that Touch Diamond does not support the 1700 mhz band???
The U.S. 3G Diamond will definitely not play nice with T-Mobile's 3G network, and there's really no way around it because of the hardware it has. Sorry. The Dream/G1 was designed specifically for T-Mobile, so it supports T-Mobile's 1700 3G band, natch.

Upgrade the radio software to connect 3G

Hello to all. Bought a week ago TD2 released in New York to use it in Brazil, net 3G of the operator Claro. It happens here in Brazil operates in the TD2 not 3G for data transmission and is always in EDGE mode, although there is availability of the 3G network. I heard that HTC has limitations in the software radio to create niche selling to carriers, so the same hardware, with tables of frequency band, or can not work on different carriers using the same frequency of band. I ask if the exchange of software to radio TD2 can make it recognize the 3G network.
Thanks in advance

Claro uses the 850/1900 MHz band for 3G.
You've probably bought the European version of the TD2 which only supports 900/2100 MHz bands.
This is defined by hardware - you can't change it by flashing a different radio.

[Q] tilt 2 3g help

im wondering. is there any way i can get 3g working on my unlocked atat tilt 2. im using cincinnati bell wireless now but im thinking bout switching phones because i cant use 3g thx.
Snooping around the net, I've found that Bell Wireless in Cincinatti uses 1700/2100 MHz bands for 3G. Both bands are needed for 3G (one is upload, one is download), similar to T-Mob.
The At&T Tilt2 isn't compatible with the 1700 MHz band. Its a hardware issue, so no software or tweaks are going to get you 3G. If you get an unlocked T-Mob branded version of the Touch Pro 2, it should work on your network's 3G.
This should be in the General section, not ROM Development.

[Q] hd 7 tmobile 3g

hello there!
i pretend to buy a hd7 front tmobile in ebay, but i want to know if it use 3g in 850m z band
in gsmarea say that have it but in t mobile version rellay dont know
regards
According to HTC's Website, the T-Mobile HD7 has the 1700/2100 MHz 3G frequencies. The AT&T version when it comes out (HD7S) should have the 850 MHz frequency you need as according to HTC's site, the surround they have uses 2100/1900/850 so it is plausible the HD7S will have the same specs.
i have a new hd7s branded att how can i unlock it to use my tmobile sim and would i still get the same network speed etc

You wouldn't get 3G speeds. T-Mobile needs 1700/2100MHz. HD7S has 850/1900.
