Hey NSers.
I bought a Nexus S just about the week it came out from Best Buy, but I've decided to move on to another phone. I had thought that purchasing it from Best Buy meant that it shipped unlocked, with no specific carrier, but I just tried an AT&T SIM card in the phone, and it gets no service.
I called T-Mobile, but the woman I spoke to informed me that they couldn't request an unlock code because it's not a phone they actually support.
So I'm wondering how I can unlock it.
Right now, its bootloader is unlocked and it's rooted, if that makes any difference (I'm hoping there will be something easy I can do that doesn't involve contacting either Google or Samsung).
Thanks in advance for any guidance.
your nexus s IS unlocked as of google phones.
the problem is that the nexus s does not support (hardware) AT&T cellular bands.
there is a specific model of the nexus s (I9020A if i'm not wrong) that support those AT&T bands.. sorry.

Oh, really? I thought it supported AT&T GSM bands, but not the 3G bands.
And no worries. It's an i9020T, so maybe it's unlocked but still works only with TMo. Darn.

I think he meant to say it does not support at&t 3g bands. It should work on any GSM carrier, but may not work on 3g.

Right. But if I put in an AT&T SIM, it should work with AT&T's GSM frequencies, right? I'm really not looking forward to calling Samsung tomorrow.
I should go to best buy and ask if you can swap it for a i9020A.

I9029A isn't sold in best buy. I'd go to AT&T and get a new sim card. Your phone should work just fine on AT&T, u just won't have 3G.
I've had a similar experience with the Canadian carriers, however if the carrier supports GSM bands it will work (like previously said) it's when the carrier only supports HSDPA (like Koodo in Canada does) then you need the specific Nexus S (i9020A in your case).
You could also try adding the APN to see if that will allow you to connect (Settings -> Wireless & Networks -> Mobile Networks -> Access Point Names (APN)) - the details can be found on the forums / your carriers website.
Works for me.

Works for me. I live in NYC, and I picked up a Nexus S at Best Buy over the Easter break as a quick temp phone till I got my Captivate fixed.
No 3g, but it certainly works on Edge. Makes calls, data works, syncs with google apps, etc.
Maybe you're just in a poor reception spot for ATT...
Thanks for the advice. Will retry. I'd wanted to confirm AT&T would work before I put it on eBay.
First unfortunately it's not just one version for all the carriers as some had suggested. The GSM providers phones do not support CDMA. The T-Mobile version is the only one with the new band 66 LTE. The AT&T version is the only one that supports band 30 (the fastest band in my area)

So the Verizon model is missing at&t frequencies?

Seems it had them all. I'm curious as to why the att version is. Band 17 if att themselves use the 17 in many places. It's actually one of the main bands of att and they don't have it showing

Band 12 includes band 17. If the phone truly doesn't support band 17, then I suspect that AT&T advertises the band as 12 and 17 to support it.
Guys check this eBay listing, there's something funny about it, 232298704354
Selling cheaper, one unit, faster than official shipping.
The seller feed back is off from picture to details of feedback and also the items sold are entirely different than phones.
Think it's a hacked account?

So what it seems like to me (im not including sprint nor did I even pay attention to it) is that the Verizon model should work great with both AT&T and Tmobile if one wanted to switch. Looks like the verizon model would be the closes to the factory unlocked model, even more so if they really dont have any Verizon branding on them. But, what is 3G TD-SCDMA that is on the GSM models?
It appears that Samsung's website is showing the same unlocked model for all carriers (G950U*), although I'm not sure why the LTE bands supported are listed (slightly) differently for each carrier. Confusingly, this is a different model than the phones being sold directly by each carrier (G950P for Sprint, G950A for AT&T, G950V for Verizon, G950T for T-Mobile). You can see that that LTE bands supported by those models are different that the G950U as well (the carrier-specific versions seem to have a subset of the LTE bands supported by the unlocked version). I was not able to locate a spec sheet for the G950P.

The links you provided are all to the Samsung website. The Samsung website does not have the same models that the carriers themselves are selling, as I tried to explain above.

So you want me to believe the 4 carrier versions Samsungs selling are not the same phones that the 4 carriers themselves are selling?
The phones I ordered from samsung are not the same as I would have gotten from the carriers directly? I'm sorry but i think it's you that is confused.

The evidence indicates that they are likely different... but you can believe whatever you want.

I don't see where the carriers list their model numbers anywhere...
Actually, here's other preorders from carriers:
AT&T (Says U)

It's the same model phone but with different FW. It is possible that specific carrier models only support their own network bands thru FW. In the past, the Samsung would actually have different radio and antenna hardware in the phones.
Given the proper FW I believe the s8 series will function identically no matter which carrier model is used provided the SIM is unlocked.
My 2 cents

That's exactly how the US S7 variants were, only difference was the firmware installed. I'm hoping for the same.
Hello, all.
I have seen similar posts to this; however, I cannot seem to get a definitive answer.
I have the Verizon 8+. I would like to throw my T-Mobile SIM card in to this device and use on T-Mobile. Reason for not purchasing the TMob phone is that I can save $$ through Verizon.
In any case, I have seen some posts that say that every carrier model contains the same LTE bands and I have seen some posts that say that certain models (VZW) may be lacking particular LTE bands required for ATT and T-Mobile.
Can anyone confirm one way or the other? Does the Verizon model (which is already unlocked) contain all the LTE bands I will need for full service on T-Mobile? Or is it worth just buying the T-Mobile variant?
Thanks in advance and I apologize for any duplicate post; however, I can not seem to find a definitive answer on this question.
Dial *#2263# on a Verizon gs8 and see what bands you can set it too.

Just go to Samsung's website and check their specs. Someone also listed the links where you can get them with a simple click.
Just off hand they all have different spectrums, it will not have all T-mobile bands, and you will lose a carrier feature or two(different standards). It will have just enough for most places.

First of all 2263 code is not valid for Verizon. Secondly Verizon blocks service mode on Samsung phones. If you want to use Verizon s8 on T-mobile, you'll have flash T-mobile firmware with odin to have all LTE bands.
The phones are the same hardware. You will need to flash the carrier firmware that you want on the device. So fkash TMO firmware on it and good to go. Thats how they did it with the S7. They all have all the bands. The firmware blocks some bands from other carriers but they do exist in the hardware.

Sadly using the newest version of Odin you can not currently flash the T-Mobile firmware. It completes successfully using Odin and even after an immediate factory reset (with the VZW sim out) it still boots up with Verizon firmware.
If anyone figures this out I'd be real happy as well, as T-Mobile is much more reliable in my area.

As the title says, I want to know what carriers IN THE US does a SM-986u1 operate on. I"m on AT&T now.
u1 is unlocked by samsung

It is an unlocked model and will work with all carriers not only in USA but throughout the world. There will be some bands not available depending on the hardware capabilities and the bands offered by the cell phone company.

Thanks. I appreciate it.
I'll be sure to identify bands on phone vs. On the carrier I want to move to.
Hi
Can't seem to get a straight answer out of Samsung live chat.
Are the confirmed frequencies and bands of S908U published somewhere?
Check www.kimovil.com. Really great site to check bands and whether device will work in a certain country and /or carrier.

Is it reliable and accurate? eg 16gb ram.
I did see that beforehand but couldn't see where they sourced the frequency info from.
