I'm interested in buying an I9000 in USA,but since i don't really have a clue if its "unlocked" or "simfree" I need your help.
My question is,is the I9000 locked to a certain cellular network like T959 which is locked to T-Mobile?
If I'm buying I9000 will I be able to use it in other countries and under other cellular network providers outside of the US?
Thanks in advance!
The I9000 is the international version of the Galaxy S. The US GSM versions are the AT&T Captivate and the T-Mobile Vibrant. The Galaxy S is quad-band GSM so should work worldwide, and has 900/1900/2100MHz tri-band 3G, which are the most commonly used bands outside the US.
In the US, AT&T uses 850/1900 and T-Mobile uses 1700/2100 for 3G. Don't quote me on this, but reading around the issue it seems that the Galaxy S should be able to get 3G in areas where AT&T has 1900MHz services, but because it lacks the 1700MHz band required by T-Mobile, you won't get 3G on T-Mobile in the US.
The Galaxy S is not necessarily SIM-locked to any network, although it can be if it's bought through a carrier. If bought without a contract SIM-free it should be unlocked.
Im living in Israel and my cellular service provider uses 1800MHz so this device wont get a signal?
Happens im buying the device and its locked is there a way to unlock it?
if yes can u give me a website please?
thank u for ur answer.

buy the International UK version
that one is unlocked
and it has 1800 for voice
http://forum.xda-developers.com/wiki/index.php?title=Samsung_Galaxy_S/GT-I9000
but you will only get 2G data
It has 1800MHz GSM (for calls/texts and GPRS data). I don't think 1800MHz is used as a 3G frequency? GSMArena says that in Israel, 850MHz and 2100MHz are used, though I don't know about specific carriers.
I've not used any unlocking services, but there are websites such as this, which offers unlocking for $30 USD (only given as an example, no recommendation implied):
http://www.unlockcellphonecode.com/product_info.php/code-for-unlocking-samsung-cell-phone-p-79
However, you should be able to buy an unlocked one. I don't know if you might be able to get one more locally for less, but, for example, this UK site sells unlocked phones (you can see the icon saying "SIM FREE UNLOCKED" under the phone):

will i be able to unlock it myself if things go wrong?
and can u please give a recommended unlocking website for i9000.
ty!

it is not locked
there is no need to unlock something that is not locked
at the moment there are no unlocking website for the i9000 because there is no lock
Agreed. There is no reason for it to be locked if not bought with a contract. The I9000 is used by many carriers all around the world - there's no lock inherent to the phone.
My friend was testing out my phone and decided to put his Bell sim card into my "unlocked" T-Mobile HD2. The problem we couldn't figure out was why the phone wouldn't get any signal what so ever and even configured my phone to Bell Mobility settings.
I use Energy's Rom and changed some of the Band/Network setting but that didn't seem to work.
Any suggestions?
Tmo HD2 uses normal gsm and 1700/2100 hsdpa aka aws, bell does not support that. Wind mobile uses aws (which is what i am using with my hd2) all though you should get a roaming signal.
Sent from my HTC HD2 using XDA App
I know in Energy's Rom there is an option to change the 3G bands from like 850+1900 and stuff, shouldn't that work?
removed.
Is that Bell SIM card for a prepaid account? If so that's why it doesn't work. Prepaid cell services don't work the same way as regular ones, and have to use specially configured devices in order to gain a signal.
Thanks for the replies! Yes i think the Bell Sim Card is a prepaid account one. The probably explains the problems we were having.
What are some carriers that are confirmed to work with the T-Mobile HTC HD2? Rogers, Fido?, Wind?, Mobilicity?
Also want to know if i'm using Rogers would the 3G capability work. I am currently using Energy's Rom.
Roger's Wind and Mobilicity are the ones that I know for sure should work. I dunno about Fido, but basically any GSM service around the world that DOESN'T use prepaid SIM cards should work with an unlocked HD2, or any device for that matter. And as far as Roger's 3G capability I don't know, what bands does Roger's use for 3G access? The TMO US HD2 uses AWS 1700/2100.
I believe rogers uses 850/1900. Not too sure but thats what i heard. Theres an option on the rom i flashed to enable 850+1900 umts or something. Im guess that would work. Cause i know if you use the stock rom that came with the T-Mobile, you the 3G doesn't work since its like 1700/2100.

The rom will not enable 850 or 1900 umts. Ask any at&t subscriber trying to use a tmo hd2 on their network and trying to use 3g. Won't happen. If your looking for 3g, you need aws (and canada does have one, i don't remember who they are at the moment) or 2100mhz 3g/umts. gsm will work with a lot more bands.

So you are saying UMTS(2100) will work with rogers 3G? Cause i know the stock T-Mobile roms have a GSM(900+1800)+UMTS(2100) band option.

yeah but only If Rogers supports 2100 cuz i dont think they do but i could be wrong
Im using prepaid on wind mobile both voice and data.

Won't work. Bell (and Telus, Virgin, Koodo, Solo) only has 850/1900 HSPA... which this phone doesn't.
Wind, Mobilicity, Videotron have 1700 AWS so this phone will work with them, ditto for Rogers and Fido but in 2G mode only (since they have 850/1900 GSM)

It already is? The phone comes unlocked.
You can use it on any GSM carrier. Be aware, however, you will only get a 3G signal if you are using it on T-Mobile's network. You cannot use this phone on CDMA carriers(Sprint/Verizon) because of the different technologies.

Do you mean SIM unlocked the phone to be used on any GSM network? The phone is factory SIM unlocked from Samsung/Google, either you bought it full price or with the contract, still SIM unlocked. Just insert any Sim card of your choice and your good to go.
nexus
in usa it is ,,,but in uk on 02 its carrier locked as i want to put it on 3 network

What do you mean when you saying that you can use 3G only in T-mobile network??
If i put a Greek SIM card f.e. with a GSM provider, i will be unable to use 3G???
Different GSM devices use different frequencies. That is why there was an AT&T nexus1 and a T-Mobile nexus1. Both GSM phones, but different frequencies. If you use a T-mobile phone on a network like AT&T you cannot get 3g. The phone will work, with voice, and edge data, but no 3g. Pretty sure same goes for the AT&T n1 on t-mo, but I could be wrong there, too lazy to check the frequencies.
Always check to make sure your GSM provider uses the same 3g/2g frequency as your device.
I'm not smart enough to know why they are unable to build the Nexus with a radio that covers all frequencies, would be cool if somebody could elaborate on that.

You need to find what frequencies your greek provider has for 3G. The nexus s has 900 / 1700 / 2100. I think it might work as it has 2100 band, but please double check what your carrier has for 3G bands, as I don't live in europe.
So i just checked and My Provider's 3G frequency is at 2100MHz...
Also My provider's GSM frequencies are 900/1800...
That means i can't get Nexus S 3G work on my provider???

Ok from your answer i think it will work 3G on my network provider...
Here i found a usefull link to check what frequencies all providers all over the world use...
Yep, you will have 3G on your nexus s.
The Nexus S with the frequencies it uses will work on T-Mobiles 3G network in the USA and the 3g on most if not all carriers in Europe.
I have read all threads, and found very confusing answers to using the sprint variant. I have found it does have LTE bands needed for both at&t mexico and usa, the two that I use. But some webpages say it is lacking frquencies for 3g and 2g gsm.
I plan on paying for a permanent remote unlock. Would The phone be completly functinal on At&t 3g? I dont care about wifi calling.
Thanks fo any help/advice.

Yes, works fine. I have done it both LTE and 4G/3G.

How did you get the gsm bands? All frequency checker webpages say sprint variant does not have 2g/3g gsm frequencies, only cdma, and LTE. I have not bought the phone yet, I want to make sure I will be able to use it not only on LTE since some places I travel to in Mexico only has 2g/3g/gsm.
Say I got a Samsung S8 from Xfinity Mobile(Verizon Network), get unlock code from XM, can I use this phone in Cricket (AT&T GSM network). Samsung support said it is ok, but from some threads it mentioned XM Samsung phone, even after unlock, some band will be locked, may not be used on other carrier. Any one tried before?

I don't see any reason why it wouldn't work just fine. The only thing I can see would be certain carrier features not working. But otherwise should be fine
Verizon and anything related to it uses CDMA technology. Whereas Cricket uses GSM.
GSM phones can be unlocked and switch carriers, whereas CDMA carriers use network-based white lists to verify their subscribers. That means you can only switch CDMA phones with your carrier’s permission.
A list of CDMA and GSM devices can be found here
Mod Edit
However, your phone might be compatible with a GSM network as cricket.
You need to check your phone's version and bands on GSMarena https://www.gsmarena.com/samsung_galaxy_s8-8161.php
And also you need to check Cricket's bands on frequency check https://www.frequencycheck.com/carriers/cricket-wireless-united-states
However, if your phone is already unlocked, you can simply insert a Cricket sim card and try to place a call and use the data to see if it works.
Thanks, understood difference between GSM & CDMA, I read other place saying all the Samsung S8 sold in US are same hardware with different firware, as long as I got unlock code from Xfinity Mobile, then I can flash phone to the new carrier specific firmware(AT&T or Cricket - which is using ATT network), can anyone confirm?

S8 has all frequencies for both GSM and CDMA. All S8s are identical hardware wise.

You are correct.
Don't think Xfinity SGS8 will work with GSM.
I believe it will only work with other carriers on CDMA like Sprint.
This is not accurate info.

So if I was to get SM-G950 US Unlocked from retailer it should work on both GSM/CDMA.

I can't guarantee it as in the past phones have been difficult to switch between Sprint and Verizon. Verizon's will work on all but Sprint based. And vice versa. But by in all theory yes all the us based models have exact hardware. And should be able to be flashed to each carrier with the csc change thread. The if anything a byop. But the best bet would be to take it once unlocked to which ever carrier and have them Install one of there active Sims and see off it works for sure.
Again shouldn't be any issues other than a few change
what's are CSs that need to be changed?
Depends on sub-model you get. If your phone is the N950U it has the following 2G bands: GSM 850 / 900 / 1800 / 1900 & 3G bands: HSDPA 850 / 900 / 1700(AWS) / 1900 / 2100 & CDMA2000 1xEV-DO. So theoretically a Galaxy Note 8 model N950U WILL work on ALL networks provided that your phone is unlocked from the carrier branded N950U. Check this webpage for the N950U specs: gsmarena.com/samsung_galaxy_note8-8505.php#n950u
If you look at the model of the phone on the back cover it will say N950U on it. N950F does not do CDMA (Verizon & Sprint), The N950FD is the same as the N950F but the "D" means dual nano sim capable (one for each girl/guy).
