Can anyone tell me if the HD2 is compatible with 3G in Costa Rica? The USB stick that is used by the telephone company has the following specs:
HSDPA/UMTS 850/1900/2100MHz
EDGE/GPRS/GSM 850/900/1800/1900MHz
Thanks in advance.

Can you explain what data tells you this? I'd like to understand 3G a little better.

Since this thread is somewhat-related to a question I've been having, I'll ask it here:
For UMTS compatibility, do the phone and network only have to share one band?
I ask because the Telstra HD2 (UMTS 850/2100) is coming out here in Australia -- where I'm holidaying -- on Tuesday. Back home -- in Canada -- my provider (Telus) uses UMTS 850/1900.
It's been suggested to me on these forums and told to me by a tech support representative for Telus (I have a hard time trusting them, however, because they're kind of dumb) that the phone'll work on 3G with just the 850 band in common with the network, but I want to be sure.
I've done some reading on Wikipedia [also], and that seems to encourage the idea that my phone'll work back in Canada...but again...I want to be sure...
I tried doing research for you and I found out Costa Rican Electricity Institute (ICE) has contracted Huawei to build the network but unfortunatly you will need to find out that 3G frequency, could be 1900 or 2100.
The HD2 uses 2100. The USB Modem works in all frequencies so it would work everywhere.
All you need to do is find out the 3G frequency, perhaps give them a call.
From My experience travelling to Mexico, Guatemala, USA and Canada. All use 1900 3G (Except T-mobile USA uses 2100).
I haven't tried the T-mobile 2100 though so I cannot assure you if it in fact does work. I've only tried AT&T(USA), Telcel(MEX), Tigo(Guatemala) and Claro (Guatemala)
Chances are Costa Rica would fall in line with the rest of North America.
So only Edge works.
Wish you Luck!

OK, now I'm confused! It is my understanding that 3G is NOT available from T-Mobile USA using the current version of the HD2. If the HD2 uses 2100 AND T-Mobile uses the same, why is 3G not available on the HD2 in the US?
If 3G isn't available in Costa Rica because of the 1900/2100 issue, is Edge automatically available? Or could ICE simply ONLY offer 3G, with no Edge alternative?

I would really appreciate an answer on this one...
What do I have to do for an answer here?
en costa rica no te va a funcionar, salvo que tu compañia utilice 3g umts2100, y por lo que vengo leyendo utiliza umts 850, o sea que no te va a funcionar...
algo similar me pasa a mi, yo estoy en uruguay con movistar y aqui el 3g es 850/1900, asi que mi querida hd2 no funciona en 3g, igualmente corre en EDGE sin ningun problema...
salu2!

Telus, like AT&T in the States, puts 3G service on 850 MHz in some towns and on 1900 MHz in other places. Since the Testra version of the HD2 does support 850, you'll get 3G in Canada in markets where Telstra uses 850. If you travel to a Canadian city where they use 1900, your HD2 will fall back to EDGE.
So, you need to find out if Telus uses 850 in your home market before buying that Telstra phone. (By the way, JB HiFi has it for $829A now and Telstra will have it at that price on 1/19.) I can't help with where you can quickly find which frequencies are active in your area, but a friend back home may be a better source than a Telus rep. Good luck.

First of all, T-Mobile USA's 3G freq is 1700mhz or AWS, which is why the T-Mobile version of the HD2 is coming out later. Europe's 3G is on the 2100MHZ freq. You can definitely import a Euro HD2 to the U.S and use it on GSM voice but data would only do EDGE either on T-Mobile USA or AT&T.
Concerning Costa Rica, i tried to look up ICE's network information and i found this on their website: http://www.grupoice.com/swf/kolbi/preguntas_frecuente.html#tecnologia_3g
Si tenés actualmente un teléfono móvil 3G, solamente podés acceder al Plan Kölbi Básico y al Plan Ejecutivo 1000. Para comprar del Plan Básico Kölbi, podés llevar cualquier terminal móvil 3G que funcione en la banda 850 Mhz.
Translated by Google it comes out to:
If you have a 3G mobile phone today, only you can access Kolbi Basic Plan and Executive Plan 1000. To purchase the Basic Plan Kolby, can carry any 3G mobile terminal operating in the 850 Mhz band.
So ICE has 3G on the 850mhz band it seems. Now the current HD2 only handles 3G on the 900/2100mhz, so you wouldn't get ICE's 3G on it.
Now, according to Phone Arena http://www.phonearena.com/htmls/HTC-HD2-US-phone-p_4345.html , T-Mobile USA's HD2 will handle 3G on the 2100/1700/900 MHz band and GSM/EDGE on the 850/900/1800/1900 mhz band. If ICE at least offers EDGE on the 850mhz band, then the U.S version would be the one to buy.

Thank-you for your reply...I hope you haven't flown off never to be seen again...
The problem here is that Telus and Bell in Canada are CDMA carriers. From what I understand, the EDGE fallback is GSM, so if there's no 850 UMTS service, my phone just doesn't get service.

Would like clarification on this if possible...
What would happen if I buy the Australian unlocked version (Telstra's NextG with 850MHz 3G); will it work in the 3G in Costa Rica. And if I don't like the Telstra's ROM, can I flash it with the original HTC ROM desgned for Australia?

I'm sorry for disappearing for several days...I forgot that I posted here.
Telus also runs an HSPA network. A quick look through their phones shows several models with HSPA, including the HTC Hero with HSPA on 850 and 1900 along with quad-band GSM. The Telstra HD2 (HTC T9193) has HSPA on 850 and 2100 along with quad-band GSM.
Call Telus and find out how wide-spread the HSPA network is. If it covers the areas where you go and if you live in a place that uses 850 for HSPA service, then the Telstra version of the HD2 will work for you. If you live in a 1900 area, you'll fall back to EDGE. If you live in a CMDA-only area, you'll have spent a lot money on a phone that can't make phone calls.

Okay, excellent.
This is what I was concerned about -- I wasn't sure about EDGE fallback because of the CDMA/UMTS issue.
Telus' UMTS coverage is actually larger than their CDMA coverage, so that aspect isn't a problem.
I'd already gone ahead and bought the phone...JB HiFi was having a hard time keeping them in stock.
Looking forward to getting this up-and-running in Canada (running on a Vodafone pre-paid SIM at the moment) on Saturday.

Remember, if Telus is using only 1900 MHz for UMTS where you live, the HD2 will only pick up EDGE since it has no UMTS radio at 1900. If Telus runs both 850 and 1900 or just 850, you'll be very happy.
Only Edge.. hd2 has all bands option, i selected all but still no 3g or hsdpa
Hi, i'm from Venezuela,
I've just bought HD2 in Hong Kong. It is an unbranded unlocked phone. On Phone Settings i see the Band menu where i can select Network Type and Band Frecuency. i've selected GSM and GSM (1900 + 850), but hd2 only navigates on EDGE. i've also have tried selecting Auto on both Network and Band Selection, but still navigating on EDGE.
besides of HD2 i also have an Samsung Omnia bought from my cell operator (Movilnet), it is set to operate on 850 1900 mhz and it works fine on 3g and hsdpa.
my question is, if the hd2 has all bands that i could select, why it dosen't work on 3G or HSDPA.
could i flash my hd2 with other Firmware or ROM, to get 3G working? i've been reading about TELSTRA in Australia, and i think the hd2 they sell has 3G over 850 and/or 1900 mhz.
or, it wouldn't be possible to change Frequencies or 3G on hd2 bought from Hong Kong?
thanks.... i'll appreciate your....

The device does not come with all 3G bands and that is why devices that are sold in specific regions only work where bands are the same. Where the bands are different, they will not work.
Thus, if your device is not 3G compatible in your area, there is no firmware drivers that can help as this is to do with hardware components in the device. Getting the right device for your region is paramount.
Hi all !
I was thinking to buy an HD2 from t-mobile on ebay but I don't know if this will work on my italian sim, as far as I have understand by reading here and there on the forum, the T-mobile version of the HD2 operate on 1700/2100 mhz 3g frequency while almost all european carrier use only 2100 ( I got H3G on italy ...)..what do you think ?
I have also noticed that I can only install specific t-mobile custom roms on this device as the one created for the european model will brick it ..
why not just get the EU HD2 instead? Yes, the TMOUS works on 1700/2100 for 3G.
beucase the european HD2 cost much more then t-mobile version...
ah ok. I don't know if it will work with EU 3G, you may need to search this forum to find out.
I have read some post here and there but I still haven't understand it ...
i have a hd2 usa model and it works fine in the netherlands. I am busy to flash the rom the a dutch version with help from this forum.
great forum.
mhm but do you use a sim card taht does on 3G ?
please I really need help on this !
I bought a tmous one month ago and it´s running fine with vodafone 3G in Spain. This company also use 2100 frequency
it use only 2100 or 1700 and 2100 like t mobile ? because as far as I know this is not the same...
As far as I know the TMO US HD2 will only work on 1700 AND 2100 for 3G. I believe the phone uses 1700 for the transmit band and 2100 for the receive band. It cannot simultaneously transmit and receive on only 1700 or 2100. The combination of 1700/2100 is called the AWS band. If you use the HD2 in an area without AWS band coverage, then it should just fall back to old 2G GSM GPRS/EDGE
While looking at prices for the HD2, you are looking at the buy outright prices correct? these prices generally go from $450-500. The $199 offers you see for the TMO HD2 are for TMO customers who lock into a 2 year contract. You will also need to obtain a SIM unlock code from TMO US to use any other carriers SIM in this phone. You can only get a SIM unlock code after completing 3 months of your contract term.
regarding the AWS I don't know if italy is cover by this signal, as far as I know H3G in italy use only 2100 mhz like almost the rest of europe..I'll check this one anyway
Regarding the price I have checked the offert on ebay and I can get it for about 220 euro that are not 220 us dollar, this is a good offert for me also thank to the good exchange ratio...

As far as i know only North america, and possibly some of south america will be using AWS in the future
Bands and areas that use them are listed here http://en.wikipedia.org/wiki/UMTS_frequency_bands
Remember to check that it is SIM unlocked, because you'll probably have a hell of a time getting an unlock code from TMO US if you're not a customer
yea I knoe but before that I have to knoe if the it can work on Italian UMTS...it's useless to have a great phone that I can use to call people !!
I suppose that i can considering that 2 user here, one from spain and one from holland, said that they use it ...regarding the unlock I 'll sure go for one that is already unlocked but also if all go bad and it arrives locked I think that is it possibile to unlock without the code from t-mobile...also because t-mobile will never give me a code from the moment that I'm not their customer !
Yes I can confirm that T-Mobile HD2 works perfectly on 3G in Europe: I bought mine while I was in US and then I moved to Switzerland. I now have a Sunrise simcard and my HD2 works on 3G, HSPD, HSPA+ and what not. Its radio indeed works in both 2100/1700 mode AND in 2100 alone mode. It was even stated in a specs sheet on T-Mobile or HTC website (I don't have the link now but it is easy to find) that it works in both 3G modes.
thank you for the info !!
I can confirm -- I traveled in Europe this past summer with my unlocked US HD2 and got 3G in the UK and Germany using local SIM cards (T-Mobile in the UK and Plus in Germany).
this is good ..so I just need to find a good offert on ebay now !

have you unlocked your american HD2???
how you have do that??? i'am not able to do
Ciao Ragazzi
avete sbrandizzato il vostro hd2 americano
come avete fatto? io no nci riesco!!
And by work I mean 3G, HSPA, as well as LTE.
I pre-ordered the T-Mobile version, but I'd rather have the Exynos SoC, so I'm thinking of canceling the pre-order and getting the international variant.

I am also interested in this. Is there any sacrifice if I buy unlocked version from eBay? Doesn't have 1700 band.
i am very interested in the LeEco LE S3 X522 cause its a great phone for that price!
but the thing that keeps me away from buying it are the lte bands (FDD-LTE B1/B2/B3/B4/B5/B7/B8/B12/B17)
but not B20!
so im very curious to know if there is a chance und enable or unlock b20 for the phone...since L2 and S3 have both the same Snapdragon 652 processor but s3 dosent have the B20 band!
the reason why i choose s3 and l2 is the lack of Corning Gorilla Glass 3 in l2...since its not mentioned anywhere...
thx
I Also have X522 but its charger is QC 3.0 Which make me some doubt that its LE S3, On box its LE 2 is written.
did you order it from china ?
and does your phone support the lte band 20?
X522 = le s3, us variant , no b20 band. X522 include cdla earphones, qc 3.0 charger. X522 model writen on the box and the back of the phone itself, along with FCC ID.
I just received the Global Version of the Mi Note 2 from Gearbest. I installed the newly released Global Rom and just connected to the Canadian Rogers Network. On my S4 I used to see a little LTE symbol beside the 4G at the top. Since I turned this on I have to see any LTE at all. Just HSPA+ which I never saw on my S4 and 3G.
Is there any way with a Qualcomm device that I can confirm what bands are supported ? I did the *#*#4636#*#* and tried forcing it into LTE only and it would not connect to the Rogers Network. So I'm a bit confused since this thing is supposed to have all the LTE bands available.
any help appreciated.....I did Root the phone... as well
I did play around as well with the sim in slot one and slot 2 too see if there was any difference. Didn't seem to help at all.
Hi !
Can you check with the box of your Mi Note 2 ?
You must see this on the global version
http://en.miui.com/data/attachment/forum/201701/05/153904ix5fyiv54a64wyw5.jpg.thumb.jpg
On the standard version you must see 4 chinese character, like this:

Definitely check and make sure you have the correct version by referencing the box and the links troufiniou provided above. If it is indeed the Global variant, I would recommend adjusting your APN settings
I have the same issue, could you fix it? Thanks
Enviado desde mi Mi Note 2 mediante Tapatalk
Is there any other way to check if my mi note 2 is a global version or not (except symbols on the box)?. The Mi Verification check gave me that it is the 'Device model LTE 28G' which is not rly helpfull because i can not find any information about it in internet. Much thx for help in advance.
I have same problem. APN is good (double checked with carrier). Even searching for networks doesnt show lte networks..
Can someone help?
I did Mi Check and it showed Device Model LTE. Tried both sim slots. Shows Global version model 2015213 on the box.
My sim card is my lte card i was using with prior phone and lte was fine
Is that ROM related?

Under the surface
Hello I Have the mi note 2 Global. The box dysplay a big global LOGO. And the frequencies given in GSM arena are the followings:
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100
4G bands LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 17(700), 18(800), 19(800), 20(800), 25(1900), 26(850), 28(700), 29(700), 30(2300), 38(2600), 39(1900), 40(2300), 41(2500)
Speed HSPA 42.2/5.76 Mbps, LTE-A (3CA) Cat12 600/150 Mbps
Canada
2G capabilities
GSM 850, GSM 1900
3G capabilities
UMTS 850, UMTS 1700, UMTS 1900
4G capabilities
LTE 1700, LTE 2600
So you can't really guess what they mean by 4G (1700/2100) . So if there is a 4G antenna next to your house that emits phone signal over the fréqueny 1700 then you might have received a version that doesn't suit your need. (i guess it is some phones have 2100 some other have 1700 but not both). You should try to get the info of what frequencies are used by the different antennas in your surroundings. I give an exemple for france:
go to the adress here: antennesmobiles
when you specify a town (if you say paris you must still zoom a little bit but not for smaller towns). Then if you look at the frequencies used by each antenna you can see the things are much more complicated than what it seems at first sight.
For exemple look the details given for a single antenna (metro oberkampf):
FH 25.5 à 26.25 GHz
3G:
UMTS 880.1 à 889.9 MHz UMTS 925.1 à 934.9 MHz UMTS 1900.1 à 1905.1 MHz UMTS 1935.3 à 1950.1 MHz UMTS 2125.3 à 2140.1 MHz
2G:
GSM 880.1 à 889.9 MHz GSM 925.1 à 934.9 MHz GSM 1765 à 1785 MHz GSM 1860 à 1880 MHz
4G:
LTE 791 à 801 MHz LTE 832 à 842 MHz LTE 1765 à 1785 MHz LTE 1860 à 1880 MHz LTE 2535 à 2550 MHz LTE 2655 à 2670 MHz
So i think these data have to be looked at carefully as it's hard to link with the commercial given data for exemple the
frequencies used in France:
2G capabilities
GSM 900, GSM 1800
3G capabilities
UMTS 900, UMTS 2100
4G capabilities
LTE 700 (28), LTE 800 (20), LTE 1800 (3), LTE 2600 (7).
Let alone that in this listing I gave the result of one antenna belonging to only one provider.
But i Hope i have given you the track to better understand the results of your intensity signal discribed on your phone.
By the way here in France I'm almost permanently in 4g with good signal only since I have this phone because before I had a phone better suited for Algéria.
Thanks and good researches.
