Nexus S aren't locked to any carrier. They are however frequency restricted, depending on the model (tri-band, unlike Galaxy Nexus which is pentaband)
What does it mean? You can put any SIM in it, but you won't get 3G unless you have the right model for your network.
Here's the specs:
i9020a/t

Then compare to i9023 compatible frequency I linked you to earlier.

so 2g will work with any company or only companies with compatible frequencies of GSM 850 / 900 / 1800 / 1900
if a company's frequency is 1700 and its in the 3G section, then it will work perfectly, correct?

For example Koodo only offers 3G as their GSM service, no 2G.
So if no frequency the company uses is compatible with your phone (none of them matches) then you will not get any service.

If the company uses similar frequencies to those supported by your phone, then you can use one of their SIM card and you will have service.

Make sure you are actually holding an i9023. Check the model printed on IMEI label on back cover under the battery.
If gsmarena spec is correct, i9023 should work with Wind/Mobilicity but not Koodo 3G, same for i9020t.
i9020a works with Koodo 3G but not Wind/Mobilicity.
Suspect you have the i9020a model. http://www.gsmarena.com/samsung_google_nexus_s_i9020a-3920.php

oh snap, you are indeed correct! the model is i9020a

Most unlock website perform SIM(Carrier) unlock. They won't unlock additional frequency support.
Nexus phones came factory SIM unlocked. Should work in India. The quoted site will take your $16.90 and do nothing

For India, you only need phone that support 2100. So all variants of Nexus S will work.
Also see my reply in your other threads.

[Q] Full band 3G/HSDPA access. Is it possible for x920d?

I've read that my phone has only 2 frequencys 900 and 2100 for 3g. While edge have all 4 (800, 900 1900 2100). Other versions of butterfly have fool pack for 3G. How do you think is it possible to unlock those two frequencys for my phone, using another version of radio for example, or any other way.

If you wanna play with Radio Software, would need S-Off anyways first

Its already done (my dev. is rooted, by now, is it mean, that S-Off gotten?)

no, s-off is security mode off (with s-off you can flash your boot in recovery and change the splash screen and radio's) this has only been obtained for the japenese butterfly kddi.
As for the frequencies, I believe that they are staight connected to the chip set and won't be changed by a radio switch out
(In the future always look at the frequencies of your carrier and the frequencies of the phone you want before you buy it)(I have done this before, learned the hard way)

In my case the chose was between microSD slot and those frequencies, so i took device considering to unlock those bands in the future, and i think its possible, because they wont do another chip for that, its more simple to lock 2 bands.

Enable SCH-I535 (galaxy s 3 verizon) to use 2100mhz

Hi everyone, I know there is a thread already open to unlock the radio for the sch-I535:
http://forum.xda-developers.com/showthread.php?t=1895684&page=30
So far nobody was able to enable the 1900 or 1700mhz
Here in Brazil Claro network uses 2100 Mhz and I would like to know if anyone was able to enable this frequency into the sch-I535
Thank
Israel Leite

I am using Claro as we speak right now. I receive HSPA+, 3g, and EDGE. How can I verify if one is 2100mHZ?

The 2100mHZ Band is unlocked out of the Box as far as i know!!

Well, I´m with Galaxy S5 now.
I learned the lesson to only buy models with ALL frequency supported.
At the time when I was with the S3, I had a work around. There is a software called phoneinfo (really hard to find it cause they don´t have it on playstore anymore) that manually you could put it to 2100mhz, it was a pain in the ass had to change it all the time depend where you at, cause not all antenas of CLARO uses the same frequency.

Questions about LG G3 AT&T

Hello, everyone!
In my vacation trip, Setember next, I wanna buy a LG G3 in USA.
In Brazil, LG G3 has only 2gb of RAM and 16 gb of internal memory and LG G3 AT&T is cheaper (U$ 570), but I didn't find information about it.
Maybe you know the answers for my questions.
AT&T's model works on 4G LTE in 2600mhz (band 7)?
Has AT&T's model Portuguese-Brazil in language settings?
Which one is the model number of AT&T (F400, D855...)?
Can I use ROM retail of another G3 model?
I really appreciate for your help.

Operators in USA can lock phones? Can I use my SIM T-Mobile in AT&T phones?

WCDMA 850 / 1700 / 1900
GSM 850 / 900 / 1800 / 1900
yes they can, yes you can but you have to either call ATT and request the code to unlock it, which they will give, but it's often a hassle, or you can use an unlocking website like http://www.imei-unlocker.com/en/ which will cost you about $5 USD

Nice, man! Thanks!!!
I asked this becaus here in Brazil, operators can't sell locked phone anymore. I see another sellers in Amazon with "UNLOCKED" and I decided ask before buy wrong stuff.
I really appreciate.
Thanks.

How do I get more frequency working on an Indian version of S2?

So as y'all know, s2 and y2 is the exact model but differentiate from where it sales.
I got my y2 from India, currently back to Taiwan.
I wonder if there are any ways fore me to enable 900 MHz 2600Mhz LTE or 4G bands, as those two is what my cellular company provides. (Whereas my phone supports 850Mhz, 2100Mhz and all, but just not 900 MHz or 2600Mhz)
I have only found a thread with galaxy s5 I suppose, but I am a newbie here and I have absolutely no Idea what I should do.
Currently running Unlocked version MIUI 10, Android 9.
Btw, rooting wouldn't be a problem, just help me to get it working <3

I don't know, this works or not, usually in "miui" there is a region menu...

Does effect nothing with region select
