Question about my nexus one - Nexus One Q&A, Help & Troubleshooting

Been reading some Threads all over the forum but there is somehing that is not very clear to me...
I live in Mexico City and also I'm the proud owner of a Nexus one buid number EPE54B
does this mean my phone is from AT&T????
I bought it here in Mexico and was told that it was an unlocked phone...
thanks in advance

There are 2 models of the Nexus One.
What is being called T-Mobile and AT&T.
These are UNLOCKED phones, however, the difference is the GSM Radio's in them for 3G DATA service.
The one you have was designed to work on the AT&T Radio frequencies, however, will work with ANY GSM provider for voice and 2G data.

[Q] AT&T radio

I tried to get TMobile service for my Nexus one but it wouldn't pick up 3G. So I called Google tech support and they said my Nexus one is an AT&T only nexus one. What's up with that? I thought this was an unlocked phone able to handle any GSM carrier? Can I get it to work on TMobile?

maybe they meant AT&T 3G, it should pickup the EDGE network on Tmo or you are in a dead zone.

it will work on tmobiles edge service, but not on 3G. tmobile and att have different frequencies for their 3G signals. and yes, there are 2 kinds of nexus ones. one for tmobiles frequency, and one for atts frequency.
If I root the phone will I be able to use it on tmobile?
No, Tmobile runs 3G through 1700mhz band & ATT runs 3G through 850mhz & 1900mhz bands. Both carriers use 850/1900mhz bands for gprs & edge network. There is no way to change the frequencies your phone uses because its a hardware issue. This has been attempted many many times with the US always getting phones last.
This is something to determine when first buying the phone. Did t-mobile sell you the wrong version of the nexus?

There is a difference between "unlocked", meaning - any SIM can go in and the phone won't stop it from working, and "correct band for GSM/3G", which is in hardware - the phone has support for X different frequencies of GSM and Y different frequencies of UMTS (3G), and if the carrier you're trying to connect to doesn't work with any of those frequencies and works with some other ones - having a working SIM won't help you, since the phone won't find the working frequencies.
And this question was answered about 10000 times.

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

using vzw LTE device outside USA ?

LTE cards are basically next gen GSM sim cards, right?
Will a Verizon (cdma) phone that is LTE capable like the droid bionic work outside the USA?
Since LTE needs an LTE sim card, would an LTE device work outside the USA simply by removing the LTE card and inserting a local country sim card?
Thanks!
No the radio frequency is different.
Sent from my DROIDX using XDA App
If your device has an antenna that supports GSm then yes it will work. You wont get LTE of course.
Ala my Tbolt works in Europe.
I didnt' think the Tbolt had any GSM capability, where in Europe does it work az?
I have seen conflicting information on whether or not the Bionic has a GSM radio in it. On GSM Arena, they have the specs up now, and emphasize that it doesn't have a GSM radio, but when the phone went through the FCC, there are articles talking about how it will be a 'world phone'.
Does anyone work for Verizon, or actually know the situation? It baffles me that there are no LTE devices that are also usable in Europe.
Verizon piggy backs on Vodaphone's network in Eruope.
Check out http://b2b.vzw.com/international/Global_Phone/Europe/Germany.html for proof.
It isn't cheap though

Thanks for that page. I see that Verizon uses that network overseas, but it doesn't appear as though the Bionic has a GSM chip in it, does it?
There is almost zero CDMA in Europe.
Yeah, you won't get 3g speeds - but you will have basic voice and sms service.
My phone stayed at 1x the whole trip - but the vast aray of free hotspots in Munich kept me well connected.
Bionic is supposed to be a world phone with 3G service on European frequencies:

Thank you for that link. It seems that for every link that I find that says that the Bionic has a GSM chip in it, there is another link that says that it doesn't. Phonearena is a good site, so this keeps me being hopeful, but then I find sites like this: http://www.gsmarena.com/motorola_droid_bionic-3710.php
They don't have a GSM chip listed, and specifically say that, "it will not work on any GSM network worldwide."
I guess that we will not know until after it is released and Verizon is finally allowed to talk about it? I tried talking to Motorola about it, and I have e-mails out to Verizon, but I'm not getting any information back that is relevant.
Check the FCC page for the Bionic here.
It's referred to in the user manual.
Though I will say, I couldn't find the GSM stuff in the tests, so it may not have made the final cut. I guess we'll see for sure on Thursday.
The link you had was for the original Bionic (the Etna). It got canned and reworked. The code name for this version was the Targa. This also has a model number of XT875 vs. the original's XT865.
I am currently living and working overseas. I can confirm that 4G LTE does not work in China. Actually, neither does verizon's 3G, which i believe is evdo (?).
No dice on it being a world phone it looks like it.
Phone Arena posted the user manual from Verizon's site. The manual's been updated from what Moto submitted to the FCC. It looks like GSM/UMTS was dropped from the final version. Makes sense considering it wasn't mentioned in the FCC test reports.
Bummer.
I would like to make a note that this phone can work in specific countries. Yes GSM is used throughout the world as the primary network (freq. band) which this phone does not provide but, it can still work in countries that has the CDMA network capabilities.
If you look in the "Getting Started" guide which came with the phone, there are Three sections about the "Go Global", "International Calling", "International Romaning" service provided by Verizon.
What I find odd is why mention this service if this phone is not a world/global/international phone..
HERE is an Example of some Countries that this phone should work in.
Japan, Taiwan, China, South Korea, Philippines, Thailand, Bahamas, Canada, Mexico, India, etc....
for a full list you can find it on Verizon's Wireless Site.
I also called Verizon to verify if this phone will work in Japan specifically as it is a primary destination of mine. They told me that in their records, The Motorola Droid Bionic phone will work in Japan. There is though, supposedly, an issue in texting where you can receive but not send
Even if its on the list, call them to verify to be safe before making a trip with the phone.
I did also ask about Europe to verify since they use GSM and they said that it would not work there. I was testing to see if they would say something opposite to what was mentioned publicly... something possibly hidden lol
Note: The primary focus was, does this phone will work in a specific country that I might travel to while still using the Verizon's plan.
If you are looking to try and get this phone moved to another service provider in that country on the other hand, I cant guarantee that it would work or is even possible. This was not a question that I brought up to Verizon.
Also I did not ask about the 4G/3G Data plan overseas.
Bionic in Japan and China
I went to China in 2005, my CDMA phone worked fine, however it was an old phone. No smart phones in 2005. I went to Japan last year with my Droid x. Everything worked well, Navigation text, phone calls. However the entire time you are in 1x mode. No 3G service in Japan, for Verizon customers. However ATT customers often had no service. I only had no service in once place. Not in a big city.
Since Japan is moving towards LTE there is no support for 3G on the CDMA network.
I do not think an LTE World phone is ready yet, for the difference band Frequency LTE operates on in different regions of the world. I would be happy if my phone worked in Japan, and it will but you will not get fast speeds and Data is very expensive on the network. When I went it was unlimited data for $64. Now Verizon has international plans. That will give you up to 250 Mb for $100. THe good thing is at 1x, how much data can you use.
not sure why this thread is spanning more than two posts.
it's cdma. no gsm chip.
there are about a dozen countries that support cdma. google it.
well the thing is the 4g chip for LTE uses a GSM network, thus the sim card... but the GSM chip works for 700 mhz OMLY, which is a LTE network frequency ONLY, so if you roam out of country, to do texts and calls, it would have to use CDMA. Not only that, but atm verizon is the only LTE carrier to use 700mhz. (correct me if I am wrong about that) so unless verizon has LTE tours out of country (vodafone?) you only will get 4G here, and if you do get 4G out of country, not only would it cost you a arm and a leg, but if there is no CDMA in the area, you would have data only. no calls, texts, or such.

[Q] Sprint HTC One on Verizon?

Has anyone tried paying full price for an HTC One at a Sprint Store and then sticking a Verizon LTE SIM in it? The specs seem to indicate that it supports LTE band 13 that Verizon uses and the 850/1900 cdma bands that is uses?

You will not get LTE on verizon with a sprint phone.
You could do an esn swap to get 3g and voice if you wanted.

If you buy a device at full price its no different than a device bought on contract. At least that's how it is in our preferred store and the same applies to corporate as far as I know. It's no like an apple store where you can request an unlocked device. You'd still have to request to have it unlocked by Sprint international. Also considering the 1900 band is the only band that crosses over between sprint and verizon I really don't see the value. Maybe it's just me in my area but roaming is even more useless than the 0.9mb/s I get on sprint.

The HTC ONE, like nearly all modern smartphones is capable of operating on multiple frequencies, network types and communications technologies. However, my assumption is that the Sprint version is carrier locked to prevent use on other networks by default. Not sure that their unlocking process would open the phone to other networks.

You wouldn't be able to straight up put in a Verizon LTE SIM and expect it to work that would be too easy.
I would guess it's possible, but you would need a donor LTE phone. Based on looking in the HTC EVO 4g LTE forums people have put that phone on another carrier and used a donor 3g phone to get 3g working. Same could most likely be possible for the HTC One. I guess if you have enough money to buy this phone outright as well as have a donor LTE phone you can probably pay someone to do this. Only limitation would be that the 16 digit password for some programs to write specific information is most likely not available yet.

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

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:

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.

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
