ATT....any hope?

I have been a long time Tilt/Kaiser user with ATT. I have an opportunity to get my hands on a friend's G1 for dirt cheap. I understand that T-Mobile's G1 will not support ATT's 3G to it's fullest extent. I'm crossing my fingers that there is a ray of hope that with research and future ROMs that someday the G1 will be able to support an ATT sim? I guess my question is...Is this a hardware restriction for ATT, or can a ROM make this a fully functional phone for an ATT user?

"T-Mobile's G1 will not support ATT's 3G to it's fullest extent" -- More like to any extent. I would think it would be as easy as sim unlocking the phone through t-mobile (have your friend, the owner of the contract, call), then pop the att sim in and change some web settings.

I'm not sure what you're asking here. If you SIM unlock the G1 and pop an ATT sim in, it will work 100% perfectly-- with the exception that it will only get EDGE. If you're asking can a ROM [sic] make the G1's 3G radios work with ATT, the answer is no. Never. Physically impossible. There are some wild reports of people having their G1s getting some 3G roaming in certain areas with their ATT sims, but these are rare exceptions, not the norm.
If you want a device shaped like a Dream that gets ATT 3G, consider a Rogers Dream. It has the proper 850/1900 MHz 3G transceivers for ATT 3G.

This answers the question. The TMO G1 has specialized transcievers that are tuned for ONLY the TMO network, which is why unlocked TMO G1s dont get 3G on any other network. So no, with your friend's G1, unless ATT decides to change their G1 carrier bands, there is no hope of getting 3G with it ever. Its a hardware problem, not a software problem. However, as suggested, if you want to be able to get 3G on ATT, get your hands on a Rogers G1.

Nexus One Question

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

Will a T-mobile Nexus one work on Bell Mobility (Canada) network

Is it possible to get a T-mobile N1 to support the 3G Bands 850/1900 that the bell network supports? I know it is possible to flash different radios with android phones. I am still a fairly new user to android but i'am trying to learn and u can't learn with out asking questions
Thanks,
Ryan

You won't get 3G. You need the AT&T version for Telus/Bell/Rogers. You could try Wind or Mobilicity.

well that sucks, neither of those are in Nova Scotia where i am located

You could always try to look for someone to trade with, AT&T for Tmobile Nexus.
But it would probably be hard to do in person if there is no demand for it in Nova Scotia.
I don't know how safe it would be to trade by mail.

Any plans that Wind or Mobilicity will come to Nova Scotia? Just curious.

You could get it to work on Rogers GSM network but you won't get 3G, I could be wrong but I don't think Bell or Telus have GSM networks so you're out of luck there.

Oh yeah, there is that little snafu too. Even worse.
It will work on Rogers but you won't get 3G speeds.
It won't work at all on Bell/Telus.

So are you saying his Tmobile won't work on Bell/Telus at all?
But an AT&T will work fine on Telus, with 3G as well?
I am considering buying a nexus one for when I switch to telus next month.

Yes, the T-Mobile version will only work on Rogers/Fido with 2G only.
It will not work on Bell/Telus at all, ever.
It will only work on 3G on Wind Mobile and Mobilicity.
If you want full Rogers/Telus/Bell support, you need the AT&T version.

If you're a Canadian and you want a "Nexus One-like" experience on Bell/Telus/Rogers, and you're having trouble finding one with the right 3G bands...
Get an HTC Desire from Telus. Problem solved. If you don't like Sense UI you can flash it with all sorts of ROMs that will make it feel more like an N1, or you can put MIUI on it, or Cyanogen, etc...

Or according to mobile syrup(can't link) the nexus S will be on the big 3 in march

Verizon HTC 1 to T-mobile

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

[Q] Regarding 4G LTE Support outside USA

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
