Sim Question

I currently am using a Qtek 2020 as my main phone and I really like it except one thing. It uses 900/1900 USA frequencies and the company I'm using is cingular.
Well they offer a 850 USA frequency that seems to do much better indoors and just all around better signals. The reason I know is I have another phone that lets me use that freq and even indoors my signals are great.
So my question is can I buy a pay as you go sim or even get another type of sim from Cingular that will let me connect to the 850 USA frequency?
Or is that impossible due to the radio in my Qtek 2020? I did check the forums and I didn't find any info on this particular problem. I have heard of the new sim that will hold twice the info so I'm wondering if those will do what I'm wanting to do.
Thanks

Your phone is tri-band 900/1800/1900 so I think the sim for 850 wont work.

Thanks that's what I thought. Wishful thinking.....

850 mhz ?????????????????

I have seen on various sites diffrent listings for the gsm. some sites say its quad band and list 850 and some say tri-band. I just wanted to know if anyone has any conformation on if it has 850 mhz or not

Really difficult to go to the HTC website and check the specs ... is it?

like i said in the first post other sites have it listed as not quad band

Originally HTC listed it as tri-band, but bow they are saying quad-band. That's why some sites say one thing and others another.

sounds good to me. So i should be able to get this as soon as its released overseas next month and have it working on the US at&t for data and voice.
edit: nm i just noticed there is no 1900 umts. think this can be activated with a rom?

Hmmmmm....
On the htc official dutch site is says triband......

The official German site of HTC does as well:
http://www.htc.com/de/product.aspx?id=54454
(It sais that the actual capability of frequencies depends on the telephone provider, but it does not mention 8560 MHz ...)
Either there is a European/Asian version AND an US-amerik. version or the limitation is based on software (different radio firmware?). There is a Raphael 100 and a Raphael 110 - may this be the difference?

Read a bit closer dude, the Raph800 is the CDMA version (according to the sources I stated in the thread here). The AT&T ROM was signed for a RAPH110 whereas the HTC ROM was signed for a RAPH100. Im predicting the radio stack will be the desiding factor on the bands available rather than different hardware, would be quite logistically stupid if HTC had several slightly different models on the go just to satisfy the carriers band needs. Sure the cosmetics might be different outside but the core hardware really should be the same.

what is the processor speed of Raphael?

524 hz.... you can find it in all specs available.....

Mods please close this tread...after reading the first page I just got a headache from all the dumb questions that could have all been answered by visiting HTC's website.

850MHz HSDPA on US AT&T
So,the end result is that a Touch Pro MAY, at some time, work on the AT&T system in the US. However, at this point no one has it functional with any of the ROMs / Radio that are avaiable at this time.
Possibly one might be able to access the higher speed HSDPA, once the ROMs and Radios have been distributed here in the good ol' USA.
If anyone does have a solution to get the TP functional here, I would love to try it.
-Craigster

At least what i can tell, my O2 Touch Pro is a quad band phone.

850MHz HSDPA on US AT&T
The key is that it has HSDPA under 850MHz. This is what will allow the higher speeds on the US AT&T network.
What radio version is your phone using?
-Craigster

Actually all Touch Pro's are 528mhz processor. 528 MHz MSM7201a to be exact.

check this thread about the 850 band please

Is there a 850 MHz HTC Touch Pro as advertised below?

The site Popular Electronics (I have no personal connection of any kind) advertises for sale a 850 MHz Touch pro
http://www.popularelect.com/product...id=CNPmmfGZhJUCFQRJFQod5VhbrQ&tab=2&osCsid=10
and it specifies that it has an 850 MHz capability:
Quad-band GSM/GPRS/EDGE: 850/900/1800/1900 MHz (Band frequency and data speed are operator dependent)
Is this for real? All sites I have checked so far specify that the 850MHz version is not available as yet.
If the information of this site is for real, would it work for AT&T?

what a thousand dollar phone
these chinese pricks are getting ridiculous !!!(HTC)

In relation to my question: Is the 850 MHz part for real?
The actual store, btw, is in Chicago.

Correct if I'm wrong, but AFAIK all Pros are quad band GSM.

Yes, all of them have 850mhz available. And it's not Chinese, smart guy.

It is for real. Check out the specifications on the main htc website it says exactly the same thing. The Europe/Asia version will work on Verizon, but you won't be able to get WCDMA speeds. The US version has 850/1900 WCDMA, whereas the Europe/Asia version as mentioned on the HTC site has 900/2100. Would be nice if they could make one with all 4 WCDMA's
I have definitely seen some sites that claim the Touch Pro is only Tri-Band, but the HTC site would be the one to go by seeing as they made it an all

WCDMA (3G) is where it differs. All Touch Pro's do NOT have 850mhz WCDMA. You can get service everywhere, but only 3G in areas with 900/2100mhz 3G... AT&T uses 850/1900 for 3G.

First of all, it is a ROM flash, second, their specs page for english used to say triband too but they changed it to quad band...

I have a friend who works for ATT and just tested the new HTC Touch Pro (Raphael) and said that ATT is planning on releasing them in November, code named "ATT Fusion."

Of course, they claim it's real...

These guys say (of course) they got a few in stock and they sold quickly. These are actually the EUROPE/ASIA version but the rep claims they are Quadband and that 3G works on both AT&T and T-Mobile (US). They are getting more in next week.

That's interesting. Did he get to take any pictures by any slight chance?

The more I read the more I get confused.....are the phones (if as advertised) in the site mentioned on post 14 likely to be working with ATT 3G?

UMTS/HSDPA for 850/900/1900/2100 on Touch Pro
I also keep on hearing this regarding bands on the Touch Pro. Can the UMTS/HSDPA band be activated for 850/900/1900/2100 by just flashing a custom ROM or changing the Radio Version? Please someone answer this....

This is something i want to know as well. I've been doing quite a bit of searching with no answer as of yet.

I live 40 minutes from Chicago and have asked this company about AT&T, Quad Band, and actual prodoct availability.
If they have them in stock, I will drive to their store, insert my AT&T SIM card and see if it will actually work.
But first, let's see if they respond to my questions.

Good deal...

Yea...I'm close to these guys too. Actually there are about 5 electronics storefront stores all next door to each other over there on W. Devon in Chicago. I bought my last 4 unlocked GSM phones from that area. Oddly enough, Popular Electronics have NEVER been the first to have any of the phones I wanted. For the past 2 years their usual answer has been "It will be here MONDAY." But "MONDAY" takes months to come!
The guys next door at Overseas Electronics (http://www.welectronics.com/) have always gotten the phones FIRST in that area--including the TyTN II. Even the other store next door to them (http://bargainoffers.com/catalog/default.php) get the hottest GSM phones before Pop Elect. This time though, Overseas say about 3-4 weeks out for the Touch Pro...so I'm really interested to know if Pop Elect actually gets them FOR REAL "by MONDAY" this time.
Please keep us informed. Thanks!!

3G HSPA 2100 band hardware based or software? Can it be changed...

Hello,
I'm curious to know is the 3G HSPA 2100/1700 frequency hardware based or software?
For example can one change the frequency to point say at 850MHz?
I'm currently with Rogers, and their 3G network is not on the same band.
Thanks

Nah, its a hardware restriction. Tmobile did this because 2100-1700 are dedicated 3G pipelines. They device does not have 850 or 1900 wcdma only 21-1700
http://www.phonescoop.com/phones/phone.php?p=1763
this is so it can not be used on at&t 3g.
if i remember correctly 1700 is for d/l and 2100 is for u/l

i dont know much about phones....or the various cellphone network types.
But isn't a frequency a frequency? Wouldn't it be the softwares job to interpret the data on the various frequencies?

True, software could interprete the singnal, it just wouldn't be as efficient.
The easiest comparison I could make would be video enconding on a PC. You can have your PC encode a video in h.264 it will just take a while. Meanwhile your HD-DVR is doing the same thing in real time. The difference is the dedicated chip in the HD-DVR that only does h.264 encoding.
I have no idea if there's a way to get the raw signal from one of the other radios, let alone if there's enough power in the G1 to interpret it without the chip. I'd guess not on both cases.

Nice comparison... but I think it is more like a wireless router. A 802.11b router can't use 802.11g... why not they run on the same frequency? Because it isn't just the frequency you have to look at. G takes a different amount of power than B. Same with the different bands. 2100 take a different amount than 850.
If you really want to see a comparison wiki radio frequencies and you will see why cb radios and those little walkie talkies don't work on all frequencies too. There is a lot more to it than just telling the radio to go up or down a couple numbers.

Nope
Qualcomm 7201 Chipset and Baseband is fully Compatible with 850 / 1700 / 2100 / 1900 Bands
You just have to have additional Component on the Board to have additional Support
Please see the motherboard Diagram its Self Sufficient i think.

I thought it was GSM 850 / GSM 900 / GSM 1800 / GSM 1900 WCDMA 1700 / WCDMA 2100
Is GSM 850 the same as WCDMA 850?
But it looks like you answered two questions with that post... someone else was looking for pics of the phones insides. Good job finding those.

Its all hardware based and will not work on at&t 3G. The phone does not have the hardware to pick up 850/1900mhz frequency. Tmobile did this not to screw people over but because they have no need to. The phone was made for T-mobile there is no reason to support at&t bands.

Just like everyone said, it is a hardware thing. As far as I know, since T-Mobile got the short straw and got the 1700MHz band, there really isn't a "universal" phone now that can operate on all GSM and all 3G frequencies worldwide yet. Manufacturers would have to have like 9 total bands supported and with the trend towards smaller and smaller phones, it's something that gets cut early. So the short of it is this: expecting the G1 to work on AT&T's 3G band is a lot like expecting an FM-only radio to pick up AM signals.....or exactly like expecting an American FM radio to pick up all the FM stations in Japan (which uses a wider FM band.)
But keep in mind that the 1700/2100 numbers don't refer to a specific frequency, but a band of frequencies at or around the number. If you've ever used a shortwave radio, you know that they use terms like "the 11-meter band," which is a range of frequencies with a wavelength of around 11m. Luckily, the range of the 2100MHz band that T-Mobile USA uses overlaps the European band enough to make the phone work over there.

Doesn't the tilt do 1700?

Something Interesting...
I found something that might be of interest... If you install "Any Cut" and create a link for "Phone Info" (Long press on you desktop, then > Shortcut > Any Cut > Activity> Phone Info). Once created, you will have a shortcut on your desktop for "Phone Info". Click the "Phone Info" Shortcut and press the menu key. Then click the menu option "Select radio b..." From here you will have the option to change your radio band:
Set GSM/UMTS band:
Automatic
EURO Band
USA Band
Japan Band
AUS Band
AUS2 Band
This would suggest to me that the radio can be controlled via software. What do the experts think? Do you think we could get 3G working on AT&T's Network?

My phone is locked. I can't use my AT&T SIM. Sorry. But when I switch to different bands, I do loose my signal until I switch back.

I have a friend who builds small electronic devices. If I had a damaged tilt would it be possible to remove the 3G antenna and a few resistors and replace the ones in the G1 to make it work on the ATT 3G bands?
Does anyone know enough about the board construction to know what would need to be replaced?

I did use that activity to change the band to get it to work with my provider here in the United Arab Emirates. The thing is I honestly don't know what they are using, publishing reliable info is not a strong point of the operators around here. I grabbed that of a web-site:
The Middle East operators are using the primary 2.1 GHz band for the UMTS/HSDPA operation. Not too precise eh.
I used the Japan labeled band.(?)

sim unlock GI via 611
I was on the horn with CS anyway and figured it would be worth a try to ask for an unlock code request for my G1, they dont have the magic keygens at the Tmob secret base, they have to request it from the OEM, back in the day they gave them out but after many public keygens they got a bit pickier about who get the keys to the liquor cabnet.
when mine comes Ill get an at&T prepay bump sim and mess about a bit just to prove it wont work, and to everybody else ...CALL 611!! ask them for the unlock code tell um you go back and forth to Europe or Iraq or Pagopago, I may not be necessarry but I always have a bit of fun with the story, it used to be a email system send imei to "[email protected]" and get your code in a few days, the good ole dayz

The Menu is shown as the Chipset Qualcomm 7201 actually supports These Bands, But it Require Radio RF/TS Unit to Actually Push Radio Frequcny via Internal antenna. Seeing the Board Picture it only have 1700 and 2100 RF Units. So even is Chipset is compatible it can not Push the Signal or Received Signal other then it is made for. I think in Future then can alter some Hardware and make it more compatible.

So, I'm wondering if I had a broken tilt with the 850 transmit antenna chip in it if I could have that antenna module removed and put in the G1 would that be all that is needed to work on the ATT 3G network?
Anybody, know if that might work since the chipset seems to support the frequency?
I can't afford to pay more than $175 for my phone. I'm a long time ATT customer and can't/won't change carriers. So, I'm trying to get one off of Craigslist or Ebay for about $250.00 or $275.00.
If anyone knows where I can get one for that price please let me know. If I can get one I'll try the antenna replacement idea.

[Q] 3G900 on O2 UK

I have not been able to find much information about this at all, and totally forgot about it.
My 3G coverage is absolutely **** at home, but 2G is pretty decent. According to the coverage map on O2's site, I should have good 2G and 3G indoors and outdoors, but as I said, I'm lucky to get even 1 bar inside.
My question is this, how do I know what spectrum the Desire S is using? I know it supports 900 MHz 3G, but how do I check if it's using it or not? Or is there any way to force it? Because I haven't seen any improvement since the 3G900 switched on, is there anything to do with the radio perhaps?

Bump !?!?!?!?!

It's a matter of checking what networks are appearing and working out from there which one is which frequency spectrum, for me I have a Telstra Mobile (GSM), Telstra Mobile 3G (850hz) and 3Telstra (2100hz).
Scan and see what networks appear, then even Google their individual names and see if you get any responses as to what spectrum they are.

I know that my network (O2 UK) recently activated their 3G/HSPA services on the 900 Mhz band (in addition to the 2100 Mhz), in order to extend coverage.
See this: http://blog.o2.co.uk/home/2011/05/superfast-900mhz-3g-explained.html
My question is that because I have seen no difference, even in the major city centres listed there, is there a way to find out if my phone is actually trying to use the 900 Mhz band for 3G or is it just staying on 2100 Mhz, how to check, any way to force?.. etc etc etc
