fast help please (may be buying a nexxus one)

Sorry for asking for fast help but I may be buying a (used, good shape) Nexxus One (via craigslist) and have an important question.
I have ATT wireless, the old, old "blue sim" ATT wireless (with a grandfathered plan I will not get rid of). Also added "unlimited mmode data plan in time before they cancelled unlimited plans (*this is not the iphone data plan).
I currently use a Nokia E51 (symbian s60v3, wifi, decent reception, works on 3G (and switches to Edge when 3G isn't avail).
I'm looking at a Nexxus One that is unlocked, currently on Tmobile.
Question is: will this nexus one work 100% (3g and edge) on my ATT account?
and/or - Is there anything I can do to make it work? (I'd like to buy it).
I'm just not sure a unlocked Tmobile nexus one is 100% compatible or will work on ATT (or can be made to work).
it's cost is making it risky so I came here in hopes of advice and help.
I hope this is the right forum section.
Any help here is appreciated and thank you very much

You will not get 3G. Only edge. T-Mobile and AT&T use different bands for 3G.

btw: here is a link to info on my Nokia E51 (GSM arena)
gsmarena.com/nokia_e51-2106.php
Am I correct in saying that nexus one has the same bands (3g/edge) as the E51 and should work well for an updated phone?
thanks

Like I said, it depends which Nexus one. The AT&T one will only give 3G on AT&T, and the TMobile one will only give 3G on Tmobile. You can't change it, no way to hack it. If you want 3G, you need the correct version for your network.

I see, and thanks for the reply. i was thinking there is a hack/workaround but there isn't apparently.
Now, is there a like phone which still would fullfill my ATT needs (blue sim plan, 3g/edge modes, wifi capable, etc that I should be looking at...essentially like the nexus one)?
What about the HTC Desire (or is this the sam scenario)?
* again, i just can't leave this grandfathered plan, and I'm not a big iphone fan (enough to make me switch plans that is).
thanks for any advice

I just received a reply from a user on the ATT forums (very well versed with my blue plan and mmode, GSM phones) who stated this...
The Nexus One would be your best choice if you want to use AT&T Mobility's 2G & 3G network (they use 850 & 1900 MHz for both).
Now in regard to this used, unlocked Tmobile nexus it may be unusable for me...
but based on his reply, he seems to be saying an (att) Nexus one should offer the 2g (edge) and 3g band features (which I need).
Are we sure about the 3g or edge but not both in regard to the nexus one?
* got my eye set on a att nexus one (really, first it was the HTC Desire - very similar, but the band support was the concern there with the Desire)
thanks

Yes, that is exactly what I am saying. You are not listening. The Tmobile Nexus One will NOT give you 3G on AT&T.
BUT the AT&T Nexus One WILL give you 3G.
You just need to get the right one. You just need to buy the AT&T compatible Nexus One. Not the Tmobile one.

You need a Nexus One with the AT&T bands. They exist. I have one. A friend of mine is selling his in the CT area.

No, no...i'm listening, but likely not asking the question right.
I understand to get att 3g I need to get the ATT nexus one. Got it.
* And no, I will not be buying this tmobile nexus one thanks to your replies.
What I'm asking is in regard to 2g/edge ability here. Are you saying that a att nexus one will ONLY offer 3G and not offer any 2G/edge capability?
Others are saying it will also offer the 2G/edge capability as well as att's 3G (like with my E51 currently).
* see there are times when att 3G is unavil/spotty and the phone (E51 in my case) switches to 2G/edge. I just wanted to make sure the att nexus one offers this ability.
thanks

Can I inquire about this phone for sale somehow?
I was looking at this tmobile nexus one for $350, decent condition.
I'm very interested in buying an att nexus one (provided it's 100% working and condition isnt too bad).
thanks for replying guys!

My Nexus One with AT&T bands works just like every other 3G AT&T phone. It works on both EDGE and 3G. If you look at the bands it has, there's no reason it wouldn't.
You need an AT&T banded N1 to get both 3G and EDGE.
If you get the T-Mobile version, you will ONLY GET EDGE on AT&T.
That's the difference: the 3G bands are different between the two, but the EDGE bands are the same.

You can email him at t4show at gmail dot com
It's only about a month old. He bought an iPhone 4. Yuck.

thank you, i sent him an email. hopefully it's still for sale.
btw: what about the HTC Desire? issues with this on my ATT network?
http://www.gsmarena.com/htc_desire-3077.php

The desire does not have ATT 3g bands, so you will be stuck on edge. Recently they announced a usa desire which might come with proper 3g, but that phone does not yet exist. So no the desire won't work unless you just want edge.

well, your friend selling his att nexus one stopped replying so I have to assume he's either kept it or selling for a bit more on ebay/etc.
I can bid on a few on ebay that will likely end up being $500+ for slightly used, but can anyone tell me if I can still buy the att 3g version ffor $529 straight from google (as in if I order by this friday)?
or I should also ask: does anyone have an att verision nexus one they're selling?

[Q] Nexus 1 stuck on Edge signal

I just purchased a rooted Nexus 1 from eBay. It came with Cyanogen 6.0 RC3. 5.08 radio. I noticed it was always displaying an E for edge signal. I went into the phone menu (*#*#4636#*#*) to set it to WCDMA Only. It then would not get a signal at all. I set signal back (WCDMA perfered) and Flashed Cyanogen ROM again with 4.06 Radio. I still get only EDGE. I have another Nexus 1 and it goes between H and 3G (HSPA is active in my area). Does anyone have any idea what could be causing this or how to fix?

One is AT&T band and another is T-Mobile band, perhaps?

No they r for T-Mobile. The problem is it only shows edge and never 3g like it should.

Try flashing back to stock to see if it keeps doing that.

Did you check settings>wireless & networks>mobile networks "use only 2g networks" unchecked. I assume you did since you know the (*#*#4636#*#*) method, but maybe someone else will read this who needs it. If that doesn't work I would test an ATT sim card to clear my curiosity.

Yes I did check this. What will testing phone with ATT sim card do? Phone is advertised as unlocked and rooted. What am I missing?

For 3g, T-Mobile USA exclusively uses the AWS 1700/2100 MHz frequency-band, and ATT uses the 850/2100 MHz band, so a special batch of N1's were made for ATT with different hardware. If a friend's ATT sim card picks up a 3G signal, it means you can't pick up T-mobile usa.
You said the phone was advertised as unlocked and rooted. The thing to check would be to ask if the phone is compatible with ATT's 3G bands or T-mobile's 3g bands. "Unlocked for all GMS carriers" for example, only tells you that it works on all EDGE networks. I haven't seen a Nexus One that can run both 3G networks, but they may exist. (Was there anything in the ad specifically about the 3g bands?)
The ATT Nexus One is more rare, you may be able to sell or trade with someone in the marketplace here on xda or on the internet somewhere.

Sanity check: shut down the phone, take off your battery cover, remove the battery and tell us the FCC ID. It's in the second of three lines of text below where the barcodes are.
My AWS (T-Mobile) Nexus One says:
FCC ID: NM8PB99100
If you have the AT&T version it should say:
FCC ID: NM8PB99110
Note the single-digit difference. If you have the AT&T version you'll want to trade it with someone else who has the T-Mobile version in order to get 3G. If this is the case, you're in luck, because the AT&T version is discontinued and lots of people would be very happy to obtain one from you.

Thanks for the information. You hit the nail on the head! The phone is marked as one of the early AT&T Unlocked models. I also had one of my friends put his AT&T card in the phone and it picked up 3g just fine. I spoke to seller of this phone on ebay and he said he would take item back. IS THERE ANY WAY TO FIX THIS PROBLEM SO THAT PHONE WILL WORK ON T-MOBILE?

Take it back to the seller or trade with someone

As many already stated in the thread (starting with me), you have AT&T Nexus, and there is NO WAY to make it work with T-Mobile. But, as also stated, you're lucky - lot of people will probably be happy to trade with you or buy it from you.

I just got a flawless AT&T Nexus One for next to nada $150 from a guy that heads up the IT department at a hospital, he had bought over a dozen f them and I mistakenly thought that since they were Google Nexus devices and since I had a "android data plan" and because I could make and receive calls and get on the web that all was good! What I didn't realize is that I'd be stuck on EDGE for good, they only real downside is that I cannot be on a call and surf the web at the same time, I'm just glad I got a pristine phone that's outta warranty, and running 2.3.6 (stock) and for only $150! Also I've always been a physical keyboard guy, so darn I get EDGE... I run the fastest web on my WEP encrypted network at home and hop on the VPN network at school, and now that the bastards at TMOB don't offer (unlimited) I really don't use alot of data anyways cause I don't goto social networking sites neways!
Any one wanting to trade a TMOB NEXUS ONE for a ATT NEXUS ONE??

[Q] Is the Nexus One not True "Unlocked?" AT&T Not working.

Hi all,
I sold my Nexus One on ebay as being "unlocked" and working with both AT&T and T-Mobile. it worked fine for 3G on my T-Mobile account, but the buyer said when he put his AT&T sim card in it though it only worked on the edge network. He pulled off the battery and checked the FCC id number and it is nm8PB99100, which matches the ID number on the box. This means it's the T-Mobile 3G version and not the AT&T version, the AT&T version would be 99110.
He said the 3G AT&T version is the 850/1900 model, which mine was not.
What exactly can I do in this situation? Thanks for any help.

easy, just tell him to switch carriers

t-mobile and at&t use different frequencies for their 3g network.
That's why Google has a T-Mobile version of the N1, and an at&t version. The t-mobile that works with t-mobile 3g, does NOT work with at&t 3g. And vice versa. The guy is screwed and can use at&t edge network, but not 3g.

He is not screwed, I've been using the t-mobile version on att for about a year and it's not to bag. I use wifi at home and at work.

I think the he's screwed referred to his desire to get 3G reception on AT&T with a T-Mo Nexus One.

You can ask for your phone back, refund the buyer and know your facts next time.

The phone IS unlocked. Meaning it works with Tmobile or ATT. So you did get it right there. Just like the others are saying. Tmobile N1 wont work on ATT 3G and visa versa. If you never stated that it will work on ATT 3G in the beginning i dont see it as your fault. The user should of asked questions prior to buying the phone. Unlocked doesnt mean it will work on both networks 3G's service. Unlock just means the phone will work on any network with a SIM.

Unlocked means that it is not locked to a specific carrier, not that it will work on any network. Depending on your area a tmo phone may or may not be able to ride 3G. In my area it would be edge only. If you said the phone was AT&T compatible for 3G your description was incorrect, a compatible phone would support both 850 and 1900. If you said it "might" work on AT&T, area depending, then you were honest as far as a court date would go. Were it me I would offer to refund so long as the buyer payed shipping regardless of how I worded it. Usually you have to suffer to do the right thing, in this case you can do it for nothing.

thanks for all your help guys, he sent it back and i gave him a full refund and posted it back on ebay with the correct information.

Nope. I think they tired to do that before on the G1, but finally gave up and said it was impossible.

Noo because it is a hardware issue.

Just ordered T-Mobile sim cards.

I'm gonna try em out for there 20 day grace period and was wondering if there's gonna need to be anything special that needs to be done to my phone to make it work with the T-Mobile cards. Also does anyone here have a captivate on tmobile in central FL or anywhere that could tell me how their service is compared to att. Att is slow for me here in Ocala. I'm hoping T-Mobile can help me out.

sim unlock your phone. there are numerous tutorials in these forums to do so
if you think ATT is slow, wait until you put in a TMobile sim card and all you can get is EDGE network.

^This. Most ATT phones will not get anything past edge on Tmobile. (Housemate is with Tmobile and tested with Inspire 4G, Infuse 4g and my captivate. I've find it amusing that I could use his Vibrant with 3g no prob xD.) Still don't understand why ATT uses their freq that way, makes me think its just for them to be spiteful.

so ur saying theres no way to use tmobiles '4g' network on my captivate or my gfs inspire? if this is in fact the case, i will be cancelling the order.

thats absolutely what we are saying.
you will not get 3g or 4G with an ATT phone on Tmobile

Something to do how ATT uses data Only on the 1800mhz band and Tmobile uses the 850? something like that.

No more ATT Compatible SIM on Straight Talk

Im already on ATT straight talk but i tried to order another sim cause I talked someone else into it....There is no ATT compatible sim buy option anymore. Anyone know whats the scoop? They need to have the ATT sim version for their N4...

The unlocked gsm would probably be for at&t. It may have something to do with it being illegal to unlock carrier locked phones now. That's just a shot in the dark though.

Thats is a plausible theory. But it doesn't make a whole lot of sense. Someone with a phone locked and has just finished their 2 year agreement with AT&T is now unable to use straight talk service. Their could be numerous reasons why ST is no longer selling AT&T sim cards. It could be because they dont want to or something as simple as they are all out, who knows. Hopefully some news will come to light. The biggest question that comes to mind for me is what is going to happen to those of us who are using AT&T on ST? T-mobile is terrible where I live, i only get edge service and the coverage is even worse. AT&T is the way to go in Vermont.

Exactly man. Right there with you.

It is most probably that tmobile now offers compatibility with 1900, give mvno better bang for the buck, and most importantly offer "unlimited" data without hidden random throttling like ATT does.. Thus coinciding with their offerings..

I think it's simple. AT&T probably got too expensive for them.

well thats unfortunate. It makes me nervous because im using ATT on straight talk so whats stopping ST from canceling my service!

I doubt they'll cancel their current AT&T customers (yet) - they'd lose too many of them. Over the next year or so they'll probably slowly force people to switch or leave, though. Who knows.

I don't think that frequency band uses ATT HSPA network.

doesn't the unlocked gsm also say global phone?
that would be AT&T, T-mobile hasn't re-farmed 1900 everywhere yet so it should be the same as the at&t option and less confusion for most consumers that have no clue

From a little Google in what I found makes me think unlocked gsm encompasses both. At&t is 850/1900mhz and Tmob is 1700/2100mhz. Unlocked gsm is 850/1700.

That does seem odd that it is gone. I'm glad I have the AT&T sim now. T-Mobile is much faster, but I get better coverage with AT&T. Hopefully this is just a tempoary thing. I'm not sure if there is anyone else that is a MNVO for AT&T. Most I've seen are tmo only.

A tmo sim would now offer more compatability with most gsm phones.
Unlocked gsm sim only guaranteed voice and text, you got Edge for data, no 3G+ data compatibility.

I just called straight talk. They said they they are just out of stock on the att cards. He assured me they will be in stock 'within a couple of weeks'. We'll see. My VZW contract is up in march so I won't be switching for a while and can wait, but was disappointed when I jumped on the nexus 4 today and then couldn't get a sim. Worst case I'll get the t-mobile one and cut it and if I don't like the service jump to another pre-paid that uses att.

If your going T-Mo in the meantime just get the $30 plan direct from T-Mobile then switch to the ST AT&T when you drop Verizon. I don't believe the T-Mo plan on ST even has micro sim cards, you have to cut one of the standard ones down. With the T-mobile $30 plan you can order the micro sim activation kit directly from their website. I tired T-Mo out first and the reception sucked so I switched to ST AT&T two weeks later and then dropped Verizon once I saw I had good reception.
