[Q] headed back to the U.S.

So...I am headed back to the U.S. permanently and wondering if there is a way to flash the radio to make it work on the U.S. 3G networks of either ATT or T-Mobile.... if not, no biggy...ill sell it and by a new one back home.
Thanks for any info you can give.

As far as I am aware mate as long as the desire has the capability of connecting to USA Phone Bands then it should just be a case of flashing the international ROM

That's the point - an A8181 doesn't support the 3G bands for any US GSM network. You would need an A8183 which at least works on AT&T, or a Nexus One on T-Mobile. If CDMA is your bag, your HTC choices are essentially the Evo on Sprint, or the Incredible on Verizon.

guess you will be selling your desire then

[Q] International Desire, American 3g?

I'm moving to the U.S. (california if that matters) in a couple of weeks and it's time for me to buy a desire. Being from Sweden I'm used to having great 3g service and use it well. What happens if i buy the phone here (not a U.S. specific model) and bring it overseas? Will 3g work? If so, can I choose from any carrier?

No it won't - a European Desire won't give you 3G on any US Network.

it all depends on which carrier you use. I have ATT and I bought my Telstra (made for AUZ) that uses the same band for 3g as ATT does and I get great 3g in SO CAL.
if you buy one in Sweden it will not work on 3g here. You can buy one from US Cellular and it will work here but they don't have that great of coverage. You can buy a EVO from Sprint, but you won't have a sim card.
If you buy a Telstra for the US it will work in Sweden (not sure about 3g) but you will have 3g in US on ATT when you get here. I bought my from here

Thank you, that was helpful information!
Is a Desire using the 850MHz band what I need?

yes, the 850 will work on ATT 3g

I'm going to Florida on holiday next year. I intended on buying a prepaid sim for my Desire (from Orange, debranded and unlocked). I did intend using 3G if it were available but after reading some of these posts I'm now unsure this will work.
Much appreciated if anyone could give me any advice.
Many thanks.

if you have an EUR desire it will not work on 3g in the US, it has different bands. it will work for Edge. If the phone's bandwidth (networks) don't match the carrier's it does not matter what sim card you have. Most EUR world phone's will work in US but just not on 3g, it must be same bandwidth.
if you must have 3g for your hoilday then you are better buying a prepaid phone, but that won't be a Desire

Thanks for explanation, very helpful.

Hi!
Type *#*#4636#*#* in dial pad, you will get to a screen where some information and hidden settings placed in; then tap on the first item which is "telephone information", and there press "menu" button, here in the android menu the first item is "select radio-band"! when you choose this menu option you will see a list of GSM/UMTS radio-band alternatives; Automatic, EURO, USA, JAPAN, AUS, AUS2 bands"
Well I'm not expert on this particular issue, just wondering what these radio-band options are for(?) Maybe you can change your Desire's radio band to USA band and try if it works in the USA (appreciate if you supply feedback whether or not it really works)

You can't change bands that's hardware related, its cheaper to buy a TELUS desire, it has 850, 1900 bands

Unfortunately when the Telus Desire goes back to Sweden, it won't have 3G.
The US Cellular Desire won't work in Sweden at all since there's no CDMA carrier.
If it weren't so hard now to get a Nexus One I'd suggest that to you. Both version support Euro 3G and you'd use it on AT&T or T-Mobile in the US depending on which version you acquire.
The problem is, as far as I know, there are no tri-band 3G HTC Desires. There is 850/1900 (Telus), 850/2100 (Telstra) and 900/2100 (Euro). So Telstra is the only one that gives you some compromise of 3G on both continents.
On the other hand I'm pretty sure all the GSM North American Samsung Galaxy S phones (Bell Vibrant, AT&T Captivate, T-Mobile Vibrant) support the Euro 2100 band.

Buy in USA, use in Europe

Hi guys,
I bought my HTC Desire from USA and I want to use it in Europe. My seller told me I can use it only in USA. Can I unlock it and use in Europe?
Thanks in advance!

Is it a CDMA Desire from US Cellular? If so, it won't work full stop and can never be made to work.
If it isn't, you should be ok with an A8181 and an A8183, but not an A8182 which will not get European 3G.

Yes, it is CDMA Desire from US Cellular.
So now I have to give it back.
Thanks for replay!

FYI, there are no CDMA carriers in Europe. So, any phone from a US CDMA carrier cannot be made to work on a European network, with the exception being a handful of so called "world phones" which essentially have both CDMA and GSM radios.

LTE bands help.

I recently won a m8 in a contest. And through lots of searching I'm stuck, I live in the UK and my phone is from the US. I want to know if my phone has the right hardware to get lte on bands 3 and 7 as I'm on ee. But I cannot find out anywhere what hardware is inside the device, any suggestions? Thanks.

Check the preferred network (in settings) if you can enable lte connectivity.

LTE Bands
Hi!! a have the HTC One® Developer Edition (M8) and this supports the followings Bands in LTE: LTE Quad Band (Bands 17/4/2/5).
Check the exact model of your M8, with this tool: https://play.google.com/store/apps/details?id=org.tritonsoft.cidgetter&hl=es-419
Cid code is needed to find your exact model and get the description of networks supporting.

Any carrier branding (Verizon, Sprint, AT&T, T-Mobile) on the outside of the phone or on the OS (splash screen, etc.)? Mosts US M8s are branded, aside from Dev Edition, unlocked, or GPE.
As long as its a GSM M8 (Verizon and Sprint are CDMA/GSM) in theory you should be able to flash a different radio to get the proper band compatibility, even if your model doesn't officially support the needed LTE band (unlocking of bootloader and S-off required).

In the US? Sprint and Verizon, and they only work on their own networks

There is also a CID which is LRA something or other (LTE for Rural America) which is also a CDMA version. LRA uses Verizon's network, but has its own CID version. Not sure, but I think this version has the same model number as the Verizon M8.
There may be other regional carrier that use Verizon or Sprints network, with their own CIDs.
Why do you ask?
