hi everybody .. i just got HTC Desire for my wife and we have this phone for 2 days now .The phone don't read 3G and when i checked the network info the phone read EDGE and when i checked my nexus at same time i seen the network UMTS . so what i can do make this desire read 3G
Check your carrier's APN setting.
Menu->Settings->Wireless & networks->Mobile Network Settings->Access Point Names
You are on T-Mobile USA right?
Sorry but there is NO version of HTC Desire that is compatible with T-Mobile USA 3G network. No, T-Mobile in Europe does not use the same 3G bands for 3G as T-Mobile USA, so even if the phone was sold with a T-Mobile (Europe) logo on it it won't have 3G in the US.
Currently there are TWO hardware versions of the HTC Desire. The first one, A8181, is the one that is sold in Europe and Asia, and this one does not have 3G in the US. The second one, A8183, is sold in Australia by the carrier Telstra. This version is compatible with AT&T's 3G network in most part of the US, but it is not compatible with T-Mobile USA's 3G network.

You will find that very, very few "worldwide" GSM phones will work with T-Mobile US's 3G due to the split 1700/2100 AWS band that TMo US uses.
Ironically though, you can take a TMo US phone out of the US and it will happily talk 3G to most other non-US GSM networks.

Most Europe/Asian carriers only use 2100 band for 3G, so as long as your phone supports that band (most GSM phones do) you can get 3G on their network.
T-Mobile USA on the other hand, requires BOTH 1700 & 2100 bands support in order for your phone to get 3G on their network. For a long time, T-Mobile USA was the ONLY carrier in the world that use 1700 band for 3G, and therefore if a phone was not carried by T-Mobile USA it didn't have 1700 3G band support (it doesn't need to because no other carrier in the world used it). Well, lately a new Canadian wireless carrier, Wind, also employs the 1700 & 2100 bands for their 3G network... so the chance of getting more phones to support these 3G bands has slightly increased. Slightly, because Wind is a new and small carrier...
Can anyone tell me the difference between EVDO and 3g?

They are both the same. EVDO is a protocol of 3G.
To explain a little further
Verizon network = CDMA
AT&T = GSM
3G for CDMA networks use EVDO
3G for GSM networks use EDGE

Exactly right. And to my understanding, EVDO has theoretical lower data speeds than GSM 3G.
So does this go for all CDMA phones...Sprint and Verizon? Do they use the same 3G bands so (theorectically) a Verizon 3G phone should work on Sprint 3G?

Yeah, but you have to know someone that works at sprint.
if you know someone at sprint get them to activate your phone's serial number on the sprint network. Something sprint frowns upon, and most local stores wont do it for you. But yeah its possible, just not worth the effort.
It would be easier to get on metro pc's network then sprints
Most cdma phones support both 3G bands but some only support one band.
Are you planning to do this to your incredible?

I'm thinking about trying it with my Incredible 2. I just wanted to make sure it (Incredible 2) supports EvDo...because I know thats is what Sprint uses for 3g.
Sounds like it would work *if* I could get the esn registered.
Thanks for the help!
Yeah, when I used to work for [well-known retailer redacted], it was really easy for us to do with the automated system--but that was back in olden days, when a tri-mode phone (on VZW) was a Feature. When I later worked for [different well-known retailer redacted], it was still possible for us to do it if we could get in touch with cooperative sprint reps, but it wasn't nearly as trivial.
More recently, talking to one of my acquaintances who currently works in mobile retail (ha!), I got the impression that it was sort of like the iPhone on T-mo was--they've been hurting for so long that they're willing to look the other way, even if it's officially frowned upon.
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

ok so stupid question but im gonna ask it anyways lol is there anything that i can do to make it work with 3G if i dont want to buy the desire z?
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?
So I know it obviously works on AT&T network but will it work on Verizon, T-Mobile or sprint?
Tmo only gets edge for me. Wondering if its compatible on other networks. Any workarounds I'm missing?
Have a feeling I'm stuck to att if I want 3g 4g... =[
That's correct. Only T-Mobile uses the GSM network that AT&T uses, but they use them on different bands so the high-speed data is typically only going to work on one network or the other. Sprint uses EVDO and Verizon uses CDMA (if I remember correctly), so phones for each of those networks will ONLY work on that network.
I tested my unlocked Nitro on an H20 wireless sim (which just piggybacks ATT) and it worked fine. The icon was even SAYING. I had 4G. A lot of 3rd party wireless companies are still using att technically, but great as a cheaper data alternative that avoid contracts.
I plan on using this phone off contract with a carrier like that once my Verizon deal expires in February.
Hope that helps.

Does anybody notice that Verizon is now using a Sim card, just like AT&T and T-Mobile? That's because their LTE network runs on the Sim Card and not built into the phone, like CDMA...
So technically, yes, you may be able to insert a verizon LTE card into your phone, and it might work, but you most definitely won't get their LTE connection.
You know what, I should try this at work tomorrow. My coworker has a Rezound. we can switch Sims and see if it works on both phones.
Make sure you have the proper LTE APN settings for each carrier or you won't see LTE or squat!
LOL!! I forgot about that. thx Repherb.
I have CM7 loaded, but doesn't really matter what rom I load, I can't seem to get 3G data speeds. I am getting internet, so that tells me the APN is setup correctly, just not 3G. Any thoughts?
Jason
probably need to look into a different radio
Any ideas? I tried 3 different ones!

The model I have is A7272 and I have an AT&T sim. Do you think the sim tells the phone what band to use for 3G? They have the option of a T-mobile sim, does anyone think that will work?
look up the A7272 on gsm arena to see what 3G band it supports and cross reference it with ATT's 3G band
Sent from my Desire Z via XDA App
I think it was because I had an ATT sim. I got a T-mobile sim and now I'm getting "H" everywhere. Still doesn't seem as fast as Verizon's 3G, but for $45/month I can't beat it. So the A7272 supports HSDPA 900 / 2100, is that why with the T-Mobile sim I can get H, because they have a 2100 HSDPA Frequency?
AT&T uses the 850/1900 spectrum for 3g and the 700mhz spectrum for 4g.
Since your phone supports none of those, that's why.
T-Mobile uses 1700/2100 (requiring both) or 1900 for 3g/4g. now, you only have half of the 2 spectrum requirement so you probably only have "half" 3g. Tmobile uses one spectrum for upload and one for download. I don't know which one is which, but if you only have one, that means you'll only get 3g/4g speed on either uploads or downloads, but not both.
I guess I fell into this trap as well... I bought a desire z thinking I could use 3g on it with my ATT/Straight talk sim. After unlocking and re-roming, I now see the same issue, stuck on Egde, and really slow edge at that.
jch2os, did you see a difference in your service area/call quality switching to the tmobile sim? I've been really happy using an Inspire on Straight talk with ATT's network, do you feel the tmobile service is a downgrade from what you previously had with ATT/Straight talk?
Thanks for the info!
After some research via eBay and Amazon, it turns out that there is two versions of the Desire Z. There is the A7272 which supports the WCDMA 900/2100 MHz bands and the A7275 which supports the 3G 850/1900 MHz bands.
idenlover, if your device is getting EDGE on the Straight Talk sim that runs on AT&T's bands, your device is the A7272 and you should get the T-Mobile Straight Talk sim. I myself am a G2 user on T-Mobile and I can say service and calling is pretty much crystal clear except in school, where there are numerous concrete buildings. Then again, I'm based in Miami, FL so I wouldn't know how service would be on your end. I hope this helps!
if you want AT&T you need the A7275 from bell canada.
Hi all! Look like i have the same problem. I have Desire Z from Russia - with russian symbols in a hard-keyboard. And in FIDO network i have only EGDE signal - never 3G. My question: what a part of phone i need change? Antenna? GSM-module? or something other? Please don't advice me change the phone - i need this keyboard, with russian symbols!!! )
P.S. If anybody know solution this problem in software (any radio, ROM, or etc.) - please, answer me too. I don't want a lot open the phone and change any parts, only if this really needed. )
P.P.S. If it important - my h-boot is 0.84.2000.

From what I get from your problem is that your phone doesnt support the FIDO network 3g bands. I think that is hardware locked. Hopefully somebody can chime in
