Hi,
I have T-Mobile G2 from USA. My network is planning to start UMTS900 network and I would like to use it.
I know that Desire Z has UMTS on 900MHz, but G2 has 850MHz instead, so it can't see that 900 network.
I wonder if it's only a matter of ROM (radio) or it's different hardware. Does anyone know? Have G2 and Desire Z the same hardware or not? Will it be enough to change G2's radio to Desire Z's one to have UMTS900 working?

See bands in this post (and it's hardware):

So I was wrong...
OK, so there is no hope for UMTS900 on G2.
I have one more question and don't want to make new topic:
Can I flash Desire Z's radio to my G2? Will it work or brick my phone? Has anyone tried?

Hi i have been out of the loop about any new phones. I've heard that there will be a US NAM 3g desire that will be coming out soon. Is this just a Telus Desire or is it an unlocked one with 850 and 1900 3g? I don't want to sign with a carrier. If it's a non telus NAM 3g desire, any idea when it will be coming out? thanks
does anyone know the answer to this?
telus is going to be releasing an hspa version (850/1900) in a few weeks. But it'll be locked.
Hi,
I have a HTC Desire that I bought in France with Orange. The phone is now unlocked and rooted, with a LeeDroid 1.8 rom.
I'm currently in Australia with a Telstra sim card and it seems I can't use the Next G. I have the HSDPA in few cities like Sydney, but everywhere else it's only Edge.
Does someone know if my phone is able to access the Next G ? And if yes, how to do it ?
Thanks a lot !
Antoine
Looks like you bought a Desire without 850MHz. Out of luck I'm afraid. The "Next G" you are seeing is 2100MHz which your phone supports but in rural areas Telstra uses 850MHz.

Is your Desire a A8181 or a A8183? The 83 denotes Telstra NextG 850mhz support.
If you have an 81, you will get 3G signal on every carrier except Telstra. If you have the 83, you only get 3G (NextG or 3.5G) on Telstra.
Yeah I have an A8181 so it explains why it doesn't works.
Thanks for your help guys !

Well, same problem for me !
I have a 81 and had chosen Telstra for the nextg and the cover...
The 850mhz support is software or hardware ?
Is it possible to do something on my desire to be able to use the NextG network ?
Cheers,
Quentin
No.

Your best bet is to use one of the other carriers in AUS such as Optus, Vodafone or 3.
The 850 Mhz radio is hardware based, and your phone has 900 Mhz radio.
3 doesn't support 900, I think Voda are deploying 850(but don't know how far their UMTS currently extends on 900) so the only long term alternative to a new handset would be Optus.
Hello fellas. I've been with my G2 for about a month now, awesome phone, but the thing is I only can use EDGE network and not 3G.
Since my carrier here in Venezuela is Movistar, which operates in these bands: 850, 1900 Mhz.
Is there anyway to make my T-Mobile G2 work with my local carrier? Thanks in advance for the help.
Yes --- check out the HUGE APN thread here.

you just need to find the right apn for your area...
No, the T-Mobile G2 is not compatible with those UMTS bands (it only uses 1700/2100). If you wanted 3G to work, you would need to get the Desire Z NAM instead (i.e., the Bell Canada version). Probably too late since you already have the phone, but maybe you can sell your G2 and pick up one of those instead?

Yes, I made some research and the only way I can enjoy 3G is if I get the DZ Us Version...
I mostly blame the carriers in this POS country, they're so behind in technology.
If i unlock my G2 using gfree or anyother method will i still have my 3G when i switch it to AT&T from T-Mobile? does anyone know of any problems with signal and what not when it gets unlocked? thanks.

You will only be to access 2G/edge data speeds, no 3G connectivity since AT&T uses different 3G bands.. assuming you are currently using a T-Mobile G2 with the carrier T-Mobile... :?
You won't have any signal issues unless AT&T has horrible coverage where you live.
you will not change anything hardware related... you just unlock/root your phone which allows you to modify hardware and software related things. But if you don't touch the antenna software then nothing will change
@CaliBoyPhillip; when I was in the states my phone switched from AT&T and T-Mobile all the time (roaming) and still had 3g reception, the phone supports most frequencies.
no im currently using a Aria with AT&T but im getting the G2 or the G2X tomorrow. and ok so i wont lose my 3G?

G2x will work with At&ts 3g/4g. As for G2 I was told it doesn't support the 3g/4g from at&t. Remember the buy out isn't final yet.

hmmm Interesting... it was prob due to the reason that you were roaming but if he uses an AT&T SIM on his SIM unlocked G2 from T-Mobile, he won't have 3G access I think... The G2 runs on 850/900/1800/1900 for edge and 1700/2100 radio for 3G data, meanwhile AT&T operates on 850/1900 for EDGE and 850/1900 for 3G.... not compatible !
EDIT: source for the bands ATT uses for 3G gotten from here.. http://www.att.com/gen/press-room?pid=14003

THis is correct. The G2 WILL NOT work with ATT 3G. If you want 3G you need to purchase the NAM (North American Model) of the Desire Z. It is sold in Canada on the Bell Network. You can find it online unlocked and unbranded and it WILL work on ATT no problem. It is going to cost you though, 450-550 depending where you get it.
Same reason iphone won't connect to tmobile 3g...amazing people still don't understand this

Not unless you know how and which chipset to replace on the board. Ie not possible.

Nope, the phone's hardware is what decides what bands it can use.

Get a desire Z from rodgers Canada the 3g bands are the same
To bad radio isn't software
It's to bad that phones don't have the radio frequencies programmable in software (much like an fm radio). Is that even possible?
Hi Guys,
Well, this is my first time posting here, so hello to you all!
Anyway, down to my problem. I have a Desire Z A7272 running on the Australian Telstra network. I just bought a new sim card today that is Next G activated.
I have a few problems which I am hoping to solve by asking you experts First of all note that the Telstra Next G network runs on the 850mHz bandwidth, which I believe my phone does not support. Seeming as I live in regional Australia, this is undesiarable because although 21000mHz is supported and available, Telstra only runs it in the metro area, where it doesn't reach me.
I was searching the net for a couple of days until I found a forum where it explained how to lock the GSM bands. I can't link it as I have lost the page. What I did was dial *#*#4643#*#* and change the network lock to "United States". This was because in the US they don't have the 900mHz band they use the 850mHz band and I was hoping to get my phone to use the 850mHz band.
Now to my 2 problems.
1. When I locked the phone to the 850mHz band, it seems that I can't access *#*#4643#*#* anymore. I type the number in, and nothing opens. I was wondering how to fix this so I could set it up to "Automatic" again.
2. I was wondering if there is anyway hardware or software wise to be able to access and use the 850mHz network. If you could link or quote some reliable/trusted sources that would be excellent. I will take unknown sources but will do with caution, I don't want to break my 2 week old phone.
Thanks guys, sorry for the essay.
Haash.
EDIT: Please note that my phone is running Android 2.3.3 with HTC Sense 2.1.
Your phone is only capable of accessing whatever bands your hardware is designed to. I don't know the specs for your Desire Z, but if the bands you want are not listed in the hardware specs, you will NEVER get them. You would need to investigate whether there is a desire z model built to run on the gsm spectrum you need.
For example, here in the US, Tmobile and AT&T phones can be unlocked to use on each other's EDGE network. But no magic code can ever give them the hardware needed to run each other's 3G network.

Thanks, now all I need to do is get my *#*#4643#*#* working again so I can change it back to the 21000mHz network that I can use.
For anyone wondering:
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, for the Tmobile G2 (American version)
GSM:
850, 900, 1800, 1900
UMTS:
1700/2100, 2100
Thanks, does anyone know how to unlock *#*#4643#*#*?

It could possibly be that the code you're using isn't correct. I believe it is *#*#4636#*#*
