How can i change HSPA/WCDMA

Hi im having trouble w/ Blackstone witj 850 mhz 3g band. Is there a way to put this frequence of HSPA/WCDMA to work with 3G from 900/2100 to 850/2100 Mhz? Like HTC Sapphire? I`d aprec some help.
Thankz.

Is it possible to add a Cellular Network Band?

My HD2 is compatible with the Network Bands:
HSPA/WCDMA/UMTS: 900/2100 MHz
GSM: 850/900/1800/1900 MHz
My Mobile Operator works only on:HSPA/WCDMA/UMTS: 850/2100 MHz with no GSM bands. The HSPA/WCDMA/UMTS 850 MHz has a better cover and is missing in my HD2. So I'm left only with the weak HSPA/WCDMA/UMTS 2100 MHz, wich sometimes is not enough.
There is any way to add the possibility to work also on the HSPA/WCDMA/UMTS 850 MHz?
I heard than there is a version of the HD2 in Telstra company in Australia which includes the HSPA/WCDMA/UMTS 850 and 2100.

No, you must buy the Telstra version if you want 850. Sorry for the bad news.

Yes, the only way to add a band is to buy a new phone, at least in this case.

Is it a Hardware matter?

Yes.

HTC HD2 T9193 850 - 1900 Mhz ?????

Hi .. I was searching the forum because I want to purchase an HTC HD2 T9193 which, I know, has the 850 - 2100 Mhz band. But I found on the net a vendor who offers the HTC HD2 850 - 1900 Mhz band, is this right ?
On the other hand, if there is not such HD2 with 850 - 1900 Mhz band, the one with the 850 - 2100 band will pick up 3G in Canada ?

That model (850 / 1900) was supposed to come out (for AT&T most probably), but it has since been cancelled.
I'd be careful if I were you. You can find more info about it here
The Telstra model (T9193) supports 850 / 2100 MHz like you said. You'll need to check with your service provider if they support 850.

Yes. You'll need to check if ATT supports the 850mhz band IN YOUR AREA.
I'm in a North Shore Suburb of Chicago area and have excellent reception with my T9193 in the area. There are 3 dead zones I've found so far that repeatedly drops calls using the HD2's 850mhz band exclusively. Other unlocked phones I've previously owned that used the 1900mhz band exclusively did NOT drop calls in these areas however. Other than that, reception has been great. It's been reported that ATT is "supposedly" moving their entire network to the 850mhz band exclusively by end of 2010. I'm doubtful they are on target for this date given the number of cities still without any 850mhz support.

T9193
Hi guys ...thanks for your responses. Well, I know that the most important service providers in Canada (Rogers, Telus, Fido) transmit 3G in the 850 - 1900 mhz band. I suppose I will not have problems whether I use the T9193

Changing 3G frequency band from 1900 MHz to 2100 MHz on HTC Inspire 4G

How can i Change my 3G frequency band from 1900 MHz to 2100 MHz on HTC Inspire 4G, cant seem to be able to get 3G here in Nigeria because of the 1900 MHz except if i am able to get it up to 2100 MHz........Is there anyway this is possible or is it a hardware issue

Inspire doesnt have 2100mhz bands.

Using just one 3G frequency?

Hi, Im planning to buy an LG Optimus L7 II Dual P715, which is listed as having the following 3g frequencies: HSDPA 850 / 1900 / 2100
The issue is that I live in Argentina and I think that we have the following freqs: UMTS 850, UMTS 1900.
I know that this sounds like a model specific, but my real question is if just having one of the required frequencies (850) should work fine here? Im from IT, but I do not know nothing from networks, cell radio frequencies, etc. Ive searched the forum for similar questions and couldnt find anything either.
If there is someone knowledgeable from here, Im planning to use the phone dual sim capabilities with Personal and Movistar.
Thanks!
Ariel

just a small clarification, the cell phone that I intend to buy has the following frequencies: HSDPA 900 / 1900 / 2100
And here in Argentina we have: UMTS 850, UMTS 1900.
So the only frequency that I would be able to use would be: 1900, would this be enough?
Thanks.

It depends on which company you have your phone and where you live. (UMTS = 3G // HSDPA = H (3,5G)
for example
3G BANDS IN ARGENTINA:
AMBA:
- Personal: 850 y 1900 MHz.
- Movistar: 850 MHz.
- Claro: 1900 MHz.
NORTE:
- Claro: 850 y 1900 MHz.
- Movistar: 1900 MHz.
- Personal: 850 y 1900 MHz.
SUR:
- Claro: 850 y 1900 MHz.
- Movistar: 850 y 1900 MHz.
- Personal: 1900 MHz.
good luck

ok, thanks for the reply... so it wont work, I live in AMBA and will use it with Personal + Movistar.
THanks!

It depends on a few things. If the carrier uses one frequency for upstream data and one frequency for downstream data, it won't work. But even if you can only use 1900 MHz, you'll be without data in areas that use only 850 MHz.
