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

3g in Argentina

Hi,
I'm from Switzerland and I've to buy a new phone for my father that lives in argentina... the problem is that here the 3g frequencies standard for phones are 900 & 2100...
What are in argentina, I've seen that are 850 and 1900....
The only phone I've found for acceptable price is the samsung galaxy S that has 900/1900/2100 (no 850mhz!!!)... will this phone work???
last question is... if i've only quadband gsm and 900/2100 3g can I use internet also with slow velocity?

help please

nothing for now?

Motorola Defy ?
3G Network HSDPA 900 / 2100
HSDPA 1700 / 2100 or HSDPA 850 / 1900

Have a look at GSMArena Phone Finder - here you can tick the frequencies you like. The only phones that offer quadband UMTS for now are latest Nokias (for example C7, E6, X3-02) and Samsung Galaxy SII. If you buy a quadband GSM and 900/2100 UMTS phone you would be able to use only GSM in Argentina.

any way to find out what MHz your phone is working on

hi just wanted to know if you can find out what mhz that phone is running on and if it can but switched to select one over the other
the web site has
Network 4
Europe:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz
Asia Pacific:
* HSPA/WCDMA: 900/2100 MHz
* GSM: 850/900/1800/1900 MHz
but i have also read that all vodaphone dhd dont run 850 , 1800 0r 1900
thanks

Benchmark app? Find it in android market

I think he means frequency of the signal rather than of the cpu

Different frequencies serve better for different uses. Low frequencies, such as 450 MHz NMT, serve very well for countryside coverage. GSM 900 (900 MHz) is a suitable solution for light urban coverage. GSM 1800 (1.8 GHz) starts to be limited by structural walls. UMTS, at 2.1 GHz is quite similar in coverage to GSM 1800.
Higher frequencies are a disadvantage when it comes to coverage, but it is a decided advantage when it comes to capacity.
Switching between these should be handled automatically - the device will select the frequency with the strongest signal if multiple frequencies are available in that cell, or alternatively, the frequency that has capacity for more users.
I don't think there's a way to manually switch between frequencies.

Not sure how it works overseas but here in the UK different frequency bands are reserved for carriers. For example, O2 and Vodafone (and their subsidiaries) both run on the 900MHz band, whilst T-Mobile and Orange run on the 1800MHz band.
The phone will still support the other frequencies, but only if sim-unlocked and a compatible network SIM used.
So if you had a voda DHD and unlocked it and put an Orange SIM in, then it would run on the 1800MHz band.
Obviously this only applies to 2.5G - not quite so up to speed on 3G frequencies.

If the band you require isnt supported by your model of DHD then there is no way to change it, as radio frequences are hard coded into the cpu chipset

Well, you can dial *#*#4636#*#* and select phone information. There you'll find the information you need.
About switching to a different band. Not possible. All you can do is prefer WCDMA or GSM. You can't force your phone to work on 1800 even if your operator supports both 900 and 1800. Usually they have the signaling channel on 900 for better coverage and use 1800 only when you are close enough to the base station, so you won't take precious 900 resources if making a call. WCDMA is very similar. If you are close enough the network prefers you being on the higher 3G frequencies, so 2G stays available for anyone who for some reason is unable to connect to the 3G.

[Q] Which note 3 for these connections

I need a note 3 that can:
connect to AT&T LTE here in the USA
And connect to T-Mobile NL in Holland
And unlocked bootloader
ATT:
850 MHz CLR 5 UMTS/HSPA+ 21Mbit/s 4G In service
1900 MHz PCS 2 UMTS/HSPA+ 21Mbit/s 4G In service
700 MHz Block B 17 LTE 4G In service Main LTE band providing complete coverage
1700/2100 MHz AWS 4 LTE 4G In service Additional LTE band for more bandwidth in select markets
1900 MHz PCS 2 LTE 4G Service starts by the end of 2013 Additional LTE band for more bandwidth in select markets[31]
2300 MHz WCS 30 LTE 4G Approved for deployment in Oct 2012[32]

TMO:
This company uses GSM1800 as their main frequency band for communications. In 2010 T-Mobile Netherlands had some problems with 3G capacity, but after investing in the network modernization they have managed to deal with this problem. So now they provide 3G services using 2100MHz band

Am I restricted to the N900-T? or is there another one you know of.
sorry for the noob question i don't know about all the bands.
Thanks!

T-Mo NL uses the 900Mhz for 2G, 2100Mhz band for 3G, and are in the process of updating to the 900Mhz band for both 2G and 3G. (Should be finished by the end of 2016.) LTE runs on the 1800Mhz band. (I can dream these numbers by now...)
You can find the bands per phone version here: http://forum.xda-developers.com/showthread.php?t=2574886
Does the TMo US version even work with AT&T?
Both N900-t and N9005 work in terms of frequency for 2G.
You will probably not be able to use the N900T for 3G once the network upgrade is finished here, as we're going to be using the 900Mhz as the main frequency for 3G. The N900T can't see that one. The 2100Mhz will be serving as a bandwidth increaser, not as the main band.
There's a chance you won't get 4G everywhere on the N9005 when using it in the US, as it can't see the 700/1700/1900/2300Mhz frequency.
And you're going to have to root to get rid of the region lock either way if you want to use both SIMs.

Tmo version 4G will not work with AT&T 4G. I tried with my wife's phone

T-Mobile (US) devices support the same frequencies as AT&T devices. This is coming from experience and from the fact that I've pretty much memorized all the band numbers that carriers use and phones support.
If you want a Note 3 that supports AT&T LTE in the US and HSPA+ in NL, you can either get the AT&T model or the T-Mobile model. The T-Mobile model supports one extra band (1700 MHz HSPA+) that is only used on T-Mobile US (nowhere outside of North America), so it wouldn't make a difference. Just know that it CAN be used on AT&T. The other differences between the two:
1. The T-Mobile version supports Wifi Calling (if used on T-Mobile), AT&T model doesn't.
2. AT&T removes the "Network Mode" menu from the Settings menu (so you can't force EDGE for example).
3. AT&T version has a locked bootloader. T-Mobile version doesn't.
In many instances, although 900 MHz WCDMA/HSPA+ isn't listed, it's supported. I can't confirm it because I'm in the US, and GSM carriers use (total) 850/1700/1900/2100 MHz for WCDMA, not 900 MHz. I think it's just unlisted to discourage people from exporting the US models. The only LTE frequency that North America shares in common with Europe is 2600 MHz, which is supported by the phone. I believe that's only used in urban areas in Europe.
Overall the T-Mobile model is the most open in terms of bootloader and supported frequencies (though either model would work in your case).

Looking for a smart watch that will run Android and be on the 1700/2100 Frequency

Currently I am on Freedom mobile in Canada. I am looking for a standalone smart watch that has the sim capability to run 3g, 4g, lte, whatever I can get basically. I currently have a DM98 and its a really cool smart watch, but the sim will not work in it as its the incorrect frequency. I would for sure need AWS 1700 band to allow 3g and lte on older devices I assume. If anyone knows what might work it would be great. - Frequency info here - https://en.wikipedia.org/wiki/Freedom_Mobile#Radio_frequency_summary
700 MHz C block (upper) 13 LTE 4G Active / Being Deployed[102] Additional LTE band that will provide service in deeper buildings and hard to reach places. Acquired from Quebecor
1,700 MHz AWS 4 UMTS/HSDPA/HSPA+/DC-HSPA+/LTE 3G/4G Active (3G) Main band for providing 3G services. (LTE) Secondary Band that provides LTE for older devices.
1,700 MHz AWS-3 66 LTE 4G Active Primary band used for LTE service in all regions except eastern Ontario.
2,500 MHz IMT-E 7 LTE 4G Active/ Being Deployed[103] Main Band that will provide fastest LTE speeds for older devices. Acquired from Quebecor.
Thank you very much

Only ones I have found are possibly an intex which is small and dated and an LG Sports Watch 2 it looks like. If anyone has any options it would be great. Was hoping for some of the new ones like huawei smartwatch 2 but they are not compatible either. Real bummer.
