how can i know if my hero is CDMA or GSM ?
Do you have a SIM card? If yes, you've a GSM phone!

does your phone look better than the other one then its CDMA lol or if its sprint.

> hum CDMA doenst have sim card ? :O
Technically, CDMA has a downward-compatible equivalent called R-UIM cards (ie, you can stick a R-UIM card into a GSM phone, and it looks just like a SIM, but you can't use a GSM SIM card in a R-UIM phone), but Sprint and Verizon have never sold a phone that used them (they sold phones without R-UIM sockets that had an equivalent circuit soldered directly to the circuit board). The closest any Sprint/Verizon phone came to having one was the HTC Apache... the Sprint/Verizon models were identical to the international CDMA models, except the R-UIM socket was never soldered on & the hole was left empty. As a result, lots of people in India bought American Apaches and soldered on their own R-UIM sockets so they could use them in India.
As far as how to tell the difference goes... if there's still any doubt in your mind... when making a call while driving, do you hear a loud "Clack" ever few minutes when the tower does a hand-off, and hear the signal quality vary radically from moment to moment? If yes, it's GSM. If no, it's probably CDMA (CDMA calls are handled by multiple towers at once, so the signal quality is less variable while moving in a car, and there's no such thing as a hand-off in the GSM sense, because there's no one single tower handling the call to begin with.
Technically, 3G GSM (UMTS) uses W-CDMA, which has the same advantages and operation as regular CDMA. However, unless you never use the phone outside of a 3G service area, chances are pretty good that it's going to fall back on old-fashioned GSM calls at least once in a while, in which case you'll hear the thunking and signal variation while moving.
Oh, I forgot test #2: does your phone make amplified speakers output a stuttering buzz? It's GSM. CDMA phones, and GSM phones operating exclusively in 3G mode, don't do that. GSM phones do. What you're really hearing is the carrier being turned off and on multiple times per second (GSM phones share bandwidth with 2 other phones by broadcasting data in short bursts in round-robin fasion, with each phone getting to transmit during every third timeslot.

So the Hero's from England won't work on USA 3G bands correct? Does anyone know when a Hero will come out that is capable?
yes that is correct, 3g in the usa will not work on the hero. the hero will come out on october 11th for United States, many indications are hinting that the carrier will be sprint
does this lie in the hardware?
Sorry to bump this thread, but as I asked earlier. Does the 3G settings lie in the hardware, or is it customizable/changeable somehow?
No, there is nothing to "unlock" a non 1700 frequency phone to make it capable of accepting 3G speeds on T-mobile
I've no idea whether the radio in the Hero is capable of supporting T-Mobiles 3G 1700Mhz band, but I do personally find it hard to believe that HTC would manufacture 2 different GSM Heros (as opposed to a GSM and CDMA one) which differ only by the bands they support since the additional cost involved in having 2 separate production lines is probably far greater than the incremental cost of using a more capable radio in all GSM Heros.
My G1 is a US T-Mobile G1, and it works fine with the 3G bands here in Europe. In addition, if you look up the specs of the Magic on HTCs website, it does not mention the 1700MHz band, but the MyTouch 3G does support and it is essentially a Magic.
This would lead me to believe that it is likely to be a firmware rather than hardware restriction - only time will tell!

Hero coming to T-Mobile USA
By the looks of things at http://www.tmonews.com and with a bit of url manipulation I was able to navigate to this pretty convicing and helpful page.
Anyone have any better resources?

yeah, but the G1 was designed specifically for t-mobile and so the G1 itself was built to support the bands for all t-mobile networks in one device.
And as the european ones nearly all use 2100mhz, that is a slightly different case.
and as for the URL manipulation, that doesn;t always mean anything.. with the right manipulation, you can get it to show updates for one device on a page titled for a totally different model. however, it would be good if you are right!!
G1 = 1700 and 2100 MHz
Hero = 900 and 2100 MHz
So both work fine in europe (2100) but only the G1 will work with T-mo US (1700). Considering that there is no reasonable prepaid 3g data in the US anywhere, not many European travellers will miss the 1700MHz capability of their cell phone.
The choice of the 900MHz band is a bit odd, seems like the only reasonably-sized market for that would be Australia. At least it'll work when you are down-under ;-)
at the moment yeah, but many European networks are pushing to get access to the 900mhz frequency and use it for 3G once 2G gets turned off.
apparently it has better penetration into buildings or something...don't quite understand the reasons why it should be better for that, but the UK networks certainly want a bit of that action....

As a rule of thumb, the lower the frequency (longer wavelength) the deeper it is going to penetrate. Thats why you can listen to the radio inside whereas you can't see the sun (visible light=much higher frequency).
cool.
I understand now. i suppose it kinda makes sense as well, lower wavelengths tend to have more power anyway,so i shoulda figured that out....
Looking at pictures of the Rezound, it looked as if it has sim card support, is there any known way to root/unlock the phone to use on T-mobile/AT&T?? if so i need one...
no the sim card is for LTE only. Sorry! It doesn't have GSM or HSPA support. Only CDMA EvDo 1xRTT and LTE
Ah bummer. Well ill definently have to consider virizon instead of tmobile when i get my own contract

Excuse my ignorance, but just trying to sort this out. Realise it uses an LTE sim card, but as I live in China was hoping to put in a china telecom sim card and use it on their CDMA2000 network (which it does support).
This possible? Thanks in advance.
The sim card is solely for LTE if that helps. It may be possible to flash it to their network but I cannot answer a yes or no
It depends on the spectrum your LTE network uses. The phone should function CDMA only if you or your carrier know how to flash it correctly. Verizon uses a special LTE spectrum range they bought from the FCC known as C-Class if I remember correctly. It was sold after the US went from Analog to Digital TV. There were A-E Class Spectrum and C apparently was the best for whatever reason. I don't know to say anyone on here would know any more info than that in regards to the frequencies.
Thanks, I don't know how to flash it and I assume my carrier probably doesn't know how to or want to either. Shame. Really wanted this phone. It is being sold on taobao here (Chinese ebay equivalent) so maybe a solution will be found in the future.
There is a program called CDMA Workshop that most places in the US use to flash CDMA phones from major carriers to pre-paid carriers. I am sure someone over there could do the same. I lived in South Korea for 2 years, the stuff they could do was ridiculous, and I know China is the same. Actually, my neighbor is from China and is pretty tech Savvy too. I will text him later as he was just in China a couple weeks ago.
He said his girlfriend was able to bring her iPhone from China and have it flashed. Should work the other way around. As far as LTE though, beyond me.
If the qualdcom processor on the EVO is ment to support LTE which in turn uses a sim card shouldn't that make the phone a world phone I know it is suppose to have an embeded sim. But my true question is will we be able to reporgram the sim once we get root or will write have to go with more of a hardware mod if we wish to make it a world phone.

Sprint uses embedded LTE technology to my knowledge, so its not like on Verizon where there is an LTE sim card. Also, this phone is a CDMA phone, and therefore does not have a regular sim card slot (Like phones on ATT or TMo). No software modifications will change this, and I highly doubt that anyone could even attempt to make a hardware modification to make this phone a world phone. Also, and LTE sim card is not the same as a regular sim card, as they perform different actions (access to LTE and the rest of the network is seperate).
Yeah I was thinking that it does not have the slot the thing is that the processor does support gsm also I was kinda hopeing it was like the rezound it is cdma phone on Verizon. It was found out that just by removing verizons LTE sim card and adding a gsm one it allowed the phone to work as a gsm phone.
the evo lte does not have the GSM and HSPA+ radios to be a world phone
When I preordered, the rep told me it was a world phone. I didn't think she was right but I didn't say anything.
Yeah i read the same post on Engadget i think. What a bummer was hopping it was since it is rocking the same processor that the at&t one (correct me if im wrong). Plus like i also stated was hopping it was like the HTC rezound on Verizon that with a experiment it ended up working. O well .... still kinda wanna take it apart and try wouldn't be xda without some experimenting or moding.
My friend has a Droid bionic which wasn't supposed to have GSM support, but it did through some hacks on rootzwiki and using a T-Mobile sim card. I think that the s4 includes a GSM radio, so its probably possible at least if the sim card can be accessed. Lte is GSM based so it is likely that GSM support is there if software is modified like it was on the bionic.

Sure, you can use it anywhere in the world that has a compatible CDMA network.
Many identify world phone with GSM radios (which the Evo 4G LTE does not have), but CDMA (which it does have) does work well for roaming in Asia.
I've roamed with my Evo 4G across Japan, Korea, and China for both voice and data. There's a full list of countries with CDMA roaming on the Sprint website. As soon as you arrive in country (if roaming works), you receive a free text with the rates and instructions on how to make international calls.
I see this phone isn't getting released in the UK/EU first, which is..... different!
I would like to know if there are plans to release this device or a similar HTC device anytime this year in the UK/EU region.
I hope HTC it will be available for sale before the beginning of December
I would rather have had the Droid DNA/J Butterfly instead of the One X+ in the UK.
You would think that with HTC's recent financial results, that they would be looking to release this highly anticipated device in many markets as possible.
Does anyone know if the Droid DNA will work on GSM 3G HSPA networks? Obviously the LTE wont work.
I wonder if any of the Frequencies Vodafone or O2 are going to use are the same as the US ones? I do remember reading it somewhere, and I don't think they are the same.

The problem is not the LTE, it is the basic network of the phone. The Verizon network is not compatible with any European network - they use a completely different system as the base which is not GSM compatible. Same reason the Nexus 4 "world" phone works pretty much everywhere except on their network.
Until HTC make a model with different radio chips (GSM standard) this phone will only be for Verizon and a couple of Japanese networks.

From Verizon's DNA specs list:
CDMA1x/EV-DO Rev A, LTE/DO Rx diversity
Global Network: GSM (850MHz, 900MHz, 1800MHz, 1900MHz), UMTS (850MHz, 900MHz, 1900MHz, 2100MHz)
Since it has GSM, will it be possible to use in Europe or Australia?

Yes.. It's just a matter of whether or not it is unlocked out of the box like the Rezound was (Limited at first before update). Or sim locked like previous droids.

Thank you for posting this... I hate when people (read: nexus161) give outdated facts based on the way the tech ran several years ago... vzw has released several devices with a quad band antenna in the past several years. The gsm bands listed are frequencies that all gsm providers currently use at least one of so the answer to the original question is yes, in theory. I'm assuming the international bands are unlocked so there should be no issue using it with a gsm provider, however I'm not sure how vzw has played this in the past so I can't speak to how this will work in practice. My guess though? Similar to the rezound. Locked for first 6-8 months, then an unlock will roll out in an update later.
That's great, so it will work over here. I'm not bothered about 4G yet as its only in a few cities.
I'm new to this whole Verizon CDMA unlocked thing. Can I use a US T-mobile SIM card and pop it into the SIM slot and it will work? What size SIM does it use? Micro?
Do you think it will be possible to buy a Us handset and unlock it?
Will it be 4G enabled?
I just spoke with three different verizon customer service representatives and they all said the phone is locked to Verizon. Two of them said Verizon never unlocks their phones and the last one said devices can be unlocked if you have 90 days of good payment history. Is there a different way to unlock android devices other than having carriers do it for you?

Sometimes... I think you need to have S-Off though... I could be wrong though.
Just because it has GSM support in the radio, doesn't necessarily mean it has a SIM slot! If I'm not mistaken, the Photon Q or whatever the Moto slider for Sprint is has a pentaband radio but no SIM slot...
Anyone got details on that?
That phone have sim slot
That phone have SIM slot, please watch any "hands on" review and you will see that.

Sorry for asking stupid question....
I did some research, but I still can't figure out why DNA can't uses other CDMA network.
Is it the problem if radio???
According what I see, DNA is able to unlock bootloader, s-off, root.
What stuff should I waiting for? Radio?
Your answer will help me know what kind of threads I should pay attention to. Thanks a LOT in advanced!
BTW, I am planning use DNA in Taiwan with a CDMA network provider.
I had checked the hardware is fitted to my network (CDMA2000 800Mhz). Thanks for all concerned!

Hi,
First of all, you must understand that GSM & CDMA are dissimilar technologies, whereas with GSM you can easily swap between carriers so long as they have the same/supported radio frequencies and your phone is sim-unlocked, this is not possible with CDMA. CDMA devices do not use a sim card to retain your account information or activation abilities. When it comes to CDMA (from my understanding) the ESN is key, the ESN must be added to your networks (for lack of a better term at the moment) ESN database. In the United States, most CDMA carriers will not add ESN's of other carriers phones to their network, your results may be different, because of your location. If your carrier were to allow or be willing to add the ESN of the DNA you obtain to their database than there is a possibility that it may work. (I am unsure if that can just be done or if it would have to be removed from Verizon's network & so forth, because I've never personally had to do such a thing)
There is a second problem though, the LTE radio / sim card interface. Because of the way these phones work on Verizon with LTE, I am unsure if you could even activate it, because it looks like the LTE sim is needed to authenticate your account to the carrier like a regular GSM phone. I have no idea how you would activate this phone without LTE / GSM on your carrier, even with the CDMA ESN added. It seems like it would be a double edged sword, but I could be wrong in this respect.
Also at this current time, this phone has root, and an unlocked bootloader through HTCDev, but is still **S-ON**.
Though none of those things have to do with you being able to use this phone on your carrier.
If your carrier was GSM I would say go for it because this is a GSM Global phone as well, but because its CDMA that you need I really incredibly doubt you'll be able to use this phone, but I may be wrong, but until someone else states otherwise I would look for a different phone.
Hope this Helps!
I am also interested in it. How can we check it out? I should go to my CDMA carrier and ask to activate my ESN?
Where can i find ESN? In Settings-About there is only MEID, IMEI, Phone serial number and IMSIAdded
I work for a CDMA carrier in the USA and with lte on the phones now, they truly act as gsm phones. If your CDMA carrier has lte then they can give you a sim and it will activate your DNA. However, if they only operate on 2g/3g then the post above me is correct with the ESN database and will USUALLY not activate the phone (in store sales reps usually don't even have the ability). Even if they have lte, activating another carrier's phone is not in the best interest of the sales Rep and they usually won't.
YMMV

From my experience, they will not be able to activate it if they do not have lte, as they would need to have a settings file made for that phone to get it to work on their network. Nevers hurts to call and ask though.
