Hello Guys,
I am new to this forum and need some help with my DHD which I bought in Singapore.
I am using it in US with AT&T and unfortunately I am not getting 3G eventhough i have 3G service. I am getting EDGE after setting up the APN. Please let me know if there is a way to get this phone working on 3G. I have already called HTC and AT&T and they mentioned that there might be difference in the frequencies.
Thanks
DHD UMTS (3g) is 900/2100 MHz, check what your carrier provides.
My particular carrier in Thailand, TRUE, only broadcasts 850 UMTS, others here use 900/1900/2100.

Hi all,
I have a Sony Ericsson Xperia X10i, but it does not support (activated) HSPA 850 Mhz networks. Is it possible to activate this? I know that the Xperia X10a does support 850 Mhz. Is the 850Mhz HSPA option locked by software. If so, how can it be unlocked.
It's a really great phone. I already use this phone on 2G and want to switch to 3G.
Help please.
Winston
Unfortunately, like most cases of this, it is a hardware limitation. This is why they made two completely different models (X10a and X10i). It isn't just software that controls it, but it goes right down to the cellular radio in the phone itself.
Your best bet is to either switch to a network that supports the bands of the X10i (T-Mobile USA and Wind Mobile in Canada) or sell the device. I am sure some people who do use T-Mobile might be interested in the X10i as it works on that 3G network.
Thanks a lot for your quick reply. So now i know i don't have to research the internet for a solution. In my country Suriname, there is only one 3G provider, unfortunately on 850 Mhz).
Whats the difference between the LT18a and the LT18i?
a is for use in the USA, i is international.

LT18i: UMTS HSPA900,2100 GSM GPRS/EDGE 850,900,1800,1900
LT18a UMTS HSPA800,850,1900,2100 GSM GPRS/EDGE 850,900,1800,1900
look like LT18a is US version
a= america = 850MHz 3G
i= international = 900MHz 3G, but also uses 850 for GSM only (it works on america but with slow internet(GSM))

LT18a vs LT18i - HSDPA 2100 band
Hi friends,
I am looking to buy SE Arc S in USA and want its 3G/HSDPA feature to work in India also. Mostly internet surfing I will do in India and seldom in USA.
HSDPA bands supported by both models is as below:
HSDPA 900 / 2100 - LT18i
HSDPA 850 / 1900 / 2100 / 800 - LT18a
Both LT18a and LT18i operate on 2100 band for HSDPA. Is there any form of difference when Sony claims support for band 2100 HSDPA in LT18a vs LT18i OR are the hardware radio/frequency & firmware/driver exactly same for 2100 band in both models.
In India 3G/HSDPA runs on 2100 band. I am confused which one to go for.
Please provide inputs.
Thanks in Advance

Thanks. Are you using SE Arc S LT18a in India on 2100 band.
I know that LT18a will work well in USA on 2100 HSPA band, and in India also we have 3G running on 2100 band. So will in my case LT18a run on 3G seemlessly well in India as well?
Hi everyone,
It's always been known that there is a 900/2100 Defy and an 850/1900 Defy.
I got mine from my 850mhz carrier in Australia. I am visiting Hong Kong at the moment. I purchased a one2free SIM (900mhz network), changed my baseband, and got on data with full HSPDA! I can download around 200kbytes a second.
Thought I'd share for fellow travellers.

Hi, how did you change the basebands to HDSPA 850/1900?
Look up "baseband switcher for defy" in Google. You'll be surprised. It's not really news...
Thanks for your answer, but I have a Defy+ with cm7. I tried with basebandswitcher and baseband of cyanogen but didn't work, they didn't change frequencies and the phone lost signal. Do you know why? Thanks
Hi, I'm having a problem with my new HTC6500LVW from Verizon.
Almost everything works good, except for the 4G/3G connection. I'm in México and my service is provided by Telcel, they use the band AWS-1 (1700Mhz upload and 2100Mhz download) for LTE, but the problem is that I found that Verizon use 700Mhz band to provide this 4G service.
I' have already configure the APN with the specifications indicated by Telcel, but nothing... All I get is EDGE connection.
My question is... Is there a way to... unlock or add this band (AWS-1) to make it compatible with the service proided here in México???
Thanks in advanced!
Sadly, no. The hardware doesn't support it. As for 3G (HSPA if it is GSM) the phone only supports certain frequencies from the website, it appears to be 900 and 2100 mhz.
