There are loads of sites available through google (http://www.google.com/search?q=diff...-ca&ie=UTF-8&oe=UTF-8&startIndex=&startPage=1) which details the difference between the CDMA and GSM cell phone network technologies.
Seeing as you're from Canada basically Bell & Telus = CDMA. Rogers = GSM
Thank you Rumball
Hi,
I bought my HTC diamond in the US, but live in europe.
Obviously, I can't connect to the 3g network here.
Is there anything I could do? If I install European ROM will it work?
if so - which ROM should I install?
My current ROM - 1.93.422.4 WWE, 08/13/08
Thanks for your help,
Mike
It is not about the ROM but the hardware of the Diamond. There are different hardware revisions. Go to bootloader and check what you have.
It is something like DIAM100
Diam110, 64m, spl-1.93.0000
anything i can do?
thanks man!

Most european diamonds are diam100 i think, you need to check what bands you diamond supports then check the bands the network/s you wanna use, use for there 3G/HSDPA Services, see if any are compatible
how do i check which bands my diamond supports?
I just had a look on google for you mate and this is what i came up with
The US 3G unlocked Diamond supports AT&T's 850/1900MHz HSDPA network, but not T-Mobile's US 3G bands. It is dual band 3G, so there's also no support for Euro 3G. It's a quad band GSM world phone with EDGE (850/900/1800/1900MHz), and that means you can make a phone call anywhere in the world GSM service is available, and you'll have access to the slower GPRS and EDGE data networks across the world. Since it's unlocked, you can use it with any carrier's SIM.
So it looks like it duznt support Euro 3G Bands, Sorry
thats a shame..
thanks anyway
thats a shame..
thanks anyway
I cant get 3G/HSDPA with orange here anyway, it dont bother me, i just steal broadband from unsecure wifi routers lol
*Double Post* Thats wot u get for stealing broadband lol
I'm in an opposites position here...
Live in the US with a European DIAM100...lol
Hello I have a European and like to trade it for a US version.
Also I'm sure like in in almost any Phones the UMTS Antenna is the same it is only limited by the Software (Radio) Big guys even on XDA developers denid that on the new Google Nexus one but HTC/Google confirmed it is ONly the "RADIO". GUess there is the whole world with one Standard and USA/ Canada with least than 6 different standards not compatibel to the rest of the World. THe Hardware guys pruduce for this development Country USA 7 extra and incompatibel HArdware version. It is haard to beleive and from any manufacture standpoint totaly inefficent.
So i would try first the regular Radios and good luck.
Yes i did search and couldn't come up with nothing so im turning to my peers for help.
I wanted to know is there a way you can check and see if the nexus one is att branded or t-mobile? If you cannot does the att branded nexus one work with t-mobile 3g?
There's 2 GSM models. One that works with att 3g and one that works with T-Mobile 3g.
yes i know thanks for the information i was asking if there is a way to check which one is which?
AT&T has a different model number under the battery. I forget the beginning numbers but the last three numbers for T-Mobile is 100 for AT&T it is 110. Both models will work on either network's GSM networks but only AT&T's phone will get 3G on AT&T's network.
ok thanks would the att nexus one connect to 3g for t-mobile 3g i know t-mobile use different frequencies but on google they look the same
nevermind the att does not support aws please close

Hey everyone. So i have a question that i can't find on here so im going to ask it. I have a Verizon HTC one unlocked. The sim car works fine and i can do everything on the phone with the T-mobile sim card. The issue is its always Edge data. Is there a specfic APN i have to use? something im not seeing? Does anyone else have this issue? It is a stock factory HTC One, nothing custom.

I don't think the Verizon model will have the correct radio frequencies to use T-Mo's LTE or HSPA+ network, hence you're stuck on Edge. If you're staying with T-Mo, I'd suggest selling your current One and buying a T-Mo specific HTC One.

This is pulled from Verizons website
Network: LTE, CDMA/1xEVDO Rev. A (800/1900 MHz)
Global Network: EDGE/GSM (850/900/1800/1900), HSPA/UMTS(1900/2100) aGPS capable for E911 emergency location, aGPS (assisted), sGPS (simultaneous), Standalone GPS, eCompass, GLONASS
T-mobile uses the 1900 Mhz base band and the HSPA as well. So i don't see the issue in that one.

From what I can tell, nobody uses the dual 1900/2100 to achieve 4G like TMO. The UMTS referred to on that phone is for worldwide use, not US. So while it may have the frequencies, it is not set up to use them like TMO. Your software and firmware are set up to work with Verizon and overseas, not with a competitor like TMO. TMO refers to theirs as HSPA+. However, it might work on the new "reframed" 1900 bands (which is called HSPA), but those are not very highly deployed. Unfortunately, I don't see LTE on that list of frequencies. The TMO LTE is really great. EDIT: I mean TMO LTE, which is also 1700/2100.
I suppose you could try unlocking it and flashing the TMO radio, but there is an entire thread on trying to unlock TMO frequencies (in that case on the developer version), and no one has figured it out yet.
I concur that your best bet would be to sell the phone and get a TMO model.

Yeah thats what im thinking. I need to contact and t-mobile rep and see if the re-farmed LTE here. Ill call and ask.
Alright so i called the rep and he said the area i am has been re-farmed to the 1900 range and i should be getting at least HSPA/3G but im not. Very odd issue

Verison use the CDMA, maybe that's why you can only use 2.5G network, just like some phones in China, they only have GSM in common

yes but this phone has 4g lte already in it which accepts the sim card. Also, i have seen other verizon htc ones with t-mobile and never had a issue. I fell i may have to use a custom rom.

What he is referring to is that what Verizon uses as "3G" is CDMA technology. So although they (T-Mobile and Verizon) may be on the same frequency they're using totally different technologies. Just because it has a sim card slot for a Verizon sim doesn't mean the device will be compatible with another carrier's sim. A custom ROM would not resolve this issue. Your best bet would be to sell this device and purchase one from T-Mobile. :fingers-crossed:

I know what the best way to go is but i am very curious as to what is really keeping it from going out of edge. baseband? Is the TMO and Verizon radios the same? these are things i need to know! >.<

My understanding is that the devices run on different systems for 3G and different LTE bands. You wont get more than GSM compatibility (GPRS, EDGE). Hopefully it is something that a software hack can fix but if you read around all the HTC One forums you will see no one has found it. Right now it is not possible.

My question is that HTC makes phones for all T mobile verison sprint the same, so I believe its just software problem that we cant use Tmobile 4g lte on Verizon unlocked phone. SO does anyone have any comment for that?

It is hardware not software that is the issue. The T-Mobile variant has different bands than the other variants including Verizon. T-Mobile is a GSM variant while Verizon is a CDMA variant. Here is a comparison of the specs for the variants.
CDMA and GSM technology requires the antenna to be done differently. If they are not programmed to use those signals. Nothing you can dox will change it short of putting a new antenna in.

Because you can only unlock GSM. Cdma uses the serial/esn number of the device.
Has there been any update on this? I called tmobile and they said it was simply because I couldn't put in the APN. So, there's no chance that rooting the phone and putting a tmobile rom on it would fix the problem and let me get more than edge speeds.
I myself have been wondering the answer to this. The device might seem the same but under the cover they are different. The actual daughter board which the camera, vibrating thing, volume rocker, power button are connected to are fairly different from each other. The CDMA variant is not compatible with the GSM variant. Not even by adding a CDMA daughter board to the GSM motherboard and vice versa, the are made quiet differently and will not be able to use GSM bands on a CDMA m7

1. Enable USB Debugging before flashing custom recovery.
2. Make a backup via recovery before granting apk's root permission, editing system files, or flashing a new Rom

Hello.
I live in a counntry with both GSM and 4G LTE networks. Reading this thread: http://forum.xda-developers.com/desire-510/help/virgin-mobile-htc-desire-510-gsm-t2965839 for the efforts of unblocking GSM bands thre is something I don't understand. If I buy the Sprint version of the phone, it is posible for me to use it outside USA with a 4G LTE capable SIM without having to unblock GSM Bands? Or do I need to have CDMA support in my country to be able to use the phone?
Thanks.
You would need a CDMA network; it's not working on GSM networks!

The thing is, where I live, people are selling this phone very cheap (less than half the price) becasuse isn't posible to unlock it on gsm at the moment.
Did it work for you ?
Did it work for you ? cause I have the exactly the same problem with my device and I don't even know what to do till now
