Samsung Galaxy S : Unlocked In U.S
Aug 4, 2010
I'd like to get a Galaxy S for software development work and also for personal use. I'll need to use it on the AT&T network occasionally, but don't want to get the Captivate model since AT&T locks it out from installing apps from "unknown sources" (makes it difficult to develop s/w!).Anyway, the unlocked Galaxies that I've seen for sale don't have what's required to use AT&T's 3G service (they work on T-Mobile, but are mostly for the European/Asian market). The Captivate works on AT&T 3G, but as I said I'd like to stay away from it and also don't want to hack it or unlock it myself, etc.Is there any solution for this? They don't sell an unbranded, unlocked Galaxy that has the wider range of 3G connectivity?This isn't really a show-stopper since I don't have or want a full cell phone plan and won't be using it that way except for occasional testing (I'll do most of my web access over WiFi). But if I'm spending $600 for a smartphone I'd like to get the max functionality out of it.

Samsung Galaxy S 3G bands - EDGE/GPRS 900/1800/1900 (not entirely sure about this)
AT&T 3G bands - 850/1900
Can I use the International unlocked version on AT&T and get 3G coverage on ATT or do I need to have both bands 850 and 1900 in my area? I could wait for the AT&T version, but I am concerned that AT&T will change some of the features and cripple the phone. They have done this before.

I am planning on getting the Samsung Galaxy Note 3 soon but I am going to buy it unlocked. Is it possible to root an unlocked phone. I have not seen any guides on Youtube or online yet that show guides on rooting a certain unlocked phone. I want to root it as soon as it is possible to root it safely. I am going to buy it unlocked but I am not going to get a plan from T-Mobile from it until January. My main question is: Is it possible to root a smartphone that does not have a sim card in it and is bought unlocked and if there is what guide do I use(like do I use the guide for how to root the galaxy note 3 tmobile edition or att edition or verizon edition.)

I am having the worst problem with my samsung behold 2. I just recently unlocked it with a unlock code from TMobile, it was saying "no service" before i unlocked it because my Tmobile account is deactivated and now its saying the same thing when i put in my AT&T sim card. I changed the APN settings in safe mode to the new cingular settings, I have a current AT&T data plan and it still won't let me do anything? I also master reset all my settings, AND STILL NOTHING! But my AT&T sim card works fine (messaging,web,calling) in my little Nokia phone from AT&T.

Sorry if this has been asked before but I couldn't find any clear answer.
I got this phone from O2 UK, unfortunately I don't have any chance to try out other SIM card onto this phone, do you know if this phone is unlocked to any network? Can I put any other SIM than O2?

Somehow I managed to get my Samsung Google Nexus S 4g phone unlocked and rooted today. In the process I installed the TWRP recovery as per the particular instructions I had. I would like to install something called the Avatar ROM but they say I need the ClockworkMod recovery. Should that make a difference? if yes, where can I find it and how do I install it instead of the TWRP on the phone now?

This is the weirdest thing that happened to me. I got the official Tmobile unlocked code when I got my Vibrant 2 months ago. I have both ATT and Tmobile service. Very easy. There's two way to unlock it per Tmobile's instructions. Please be advised there are two different ways to unlock this device. It is very important that the instructions are followed as listed.
If using a T-mobile SIM card:
1. Put in a T-Mobile SIM card.
2. Turn on the handset.
3. Enter: #7465625*638*Unlock Code#
If using a Non T-Mobile SIM card:
1. Put in the Non T-Mobile SIM card.
2. Turn on the handset.
3. Enter the Unlock Code provided by T-Mobile.
Note: DO Not enter #7465625*638*unlock code# with a non T-Mobile SIM card, as this causes the handset to freeze.
If you receive an error message while performing the instructions do not make any further attempts to unlock the handset. Please be aware that if an excessive amount of incorrect attempts are made, the phone will be permanently locked. You will need to verify the IMEI by pressing *#06# and contact Customer Care for support. Anyways, I just popped in my ATT sim into the Vibrant and used the unlock code I was given. No problem for almost two months. I switch Tmobile/ATT sims with the Vibrant. So this past weekend, when I put the ATT sim back into the Vibrant, the phone asked for the unlocked code again. It's a good think I save all of my emails with the unlocked code. But is this normal to have an official unlock code and the phone "relocks" itself? This is the first time I've ever had a GSM phone (with either ATT or Tmobile "relock" itself").

When connecting my Galaxy-S to the Samsung Kies software, my telephone shows up with an incorrect telephone number. I did change the sim-card (and subsequent number) since first using it, but I never logged intio Kies with the old sim-card.The phone is rooted.How do I get Kies (or my Samsung phone) to show my current telephone number?In the phone properties (Menu, Settings, About, Status) the same wrong number is shown.When calling, the receiver sees the correct telephone number. So the issue is not operator related but telephone related.

Samsung should stop promoting the Galaxy Tab and fix the Galaxy S phones.Tab is running 2.2 and most likely has a fixed GPS.While the rest of us who paid for a product still have not gotten our money's worth.

I have configured my Samsung Galaxy S using my normal Gmail account. This has helped me to sync the Google Contacts with my phone.
Following are my questions:
1. Right now I have about a thousand google contacts synced to my phone. I want to remove them at one go. I know how to disable them from being appearing in contact list, but I want to know if I can delete them without going to factory settings.
2. I am using three applications (a) Gmail (b) Contacts (3) MVOIP. I want to know if there is a way that following combination works:
a- Google contacts appear on Gmail app
b- Google contacts (with phone numbers) and normal phone contacts appear on "Contacts"
c- Google contacts (with phone numbers) and normal phone contacts appear on "MVOIP application".
I know how to do
(a) - By synchronising google contacts,
(b) - by choosing display options
(c) - I do not know how to handle this and I want help.

I got AT&T Samsung Captivate i897 (2.1 Eclair). I unlocked and rooted my phone. I was using simple free phone earlier which doesn't require data plan but after two weeks I bought samsung captivate, AT&T added $25 data plan. I got my phone from AT&T store where my friend works so he took my data plan out of the plan for now but he said they will find out and add into your plan again. Also, He said that they recognize by your IMEI number. My question is: Is there anyway I can change my IMEI number? I was thinking to use my simple free Nokia phone's IMEI number and use it for Samsung Captivate so AT&T thinks that I am using Nokia phone.

After running three updates this morning. I started getting a weird light effect when I unlock my phone. It happens at the top of the screen just to the right below the battery. It's a quick yellow glow then it disappears until my phone is locked then unlocked again. One of the updates had to do with my weather widget [Weather & toggle]. Anyone seen or heard of this?

I have an unlocked captivate. I have a German T-D1 pay-as-you-go sim that I've used many times in unlocked GPS phones. Now I have an AT&T captivate and wonder whether GPS or other apps will work. Does GPS require a data plan to work? If so I'll have to figure out whetted I can add this to my T-D1 plan. This will also answer my question about whether using the Captivate for navigation in the US needs a data plan to work.

I was originally going to get either the HTC Hero or Motorola Droid but found out they are both CMDA. and the Milestone is out of my budget. People have been suggesting to get the Samsung Galaxy S, that's also out of my budget and looks too much like an iPhone. So i stumbled upon these two phones.I'm leaning more towards the Spica because it has superior battery life, and 800mhz compared to the 528mhz the i7500 has. and it can also play DivX.What's making it a difficult decision is the i7500 has an AMOLED Screen. It can display 16,777,216 Colors while the Spica can only display 65,536 Colors I'm not too sure if that will make a difference. Also it has 5mp w/LED Flash while Spica is only 3.2.One phone has a little of both. This will be my first Android phone I'm coming from a Sony Ericsson W995.

I have recently picked up a Samsung Galaxy S Captivate (Android 2.1) on Rogers Wireless. I've been having an issue with the wifi on it, it only works intermittently when I'm at home. It will connect to my network without issues, but none of the data-enabled apps can access anything, they just time out. While this is happening my old iPhone (recent android convert) and my Nintendo Wii are able to connect flawlessly. This ONLY happens when I'm at home on my own network from what I've seen, when I'm on the wifi at my work everything works fine. Has anyone seen issues like this or have any suggestions as to what may be causing it? FYI I have tried different wifi channels, currently my router is setup to use TKIP on WPA2 for encryption.

I know that some people were able to do this with the Nexus One. So has anyone (who has gotten it early) done the same?

I unlocked my Captivate a few days after the unlock came out and have been using it flawlessly for the last month or so. Well, my extra batteries came in last night so I kept taking the batteries in and out, powering the phone on and off. Then I used the new battery 'til it died and when I turned it back on, the SIM lock was on again. So I had to go through the process this morning again to unlock it. Tip: don't power on and off your unlocked Captivates too much/frequently. It'll lock up again!

If any of you own an uncloaked captivate, and also have a T-mobile phone, and you don't mind testing let me know. I want to confirm my fix, that popping in an active T-mobile sim card with data plan, will allow an unlocked Captivate to get a 3G signal. No software or root required, it is actually very easy. If you are willing to volunteer, let me know.

Met up with an old college buddy for lunch today, he's a diehard iphone user. Since my Vibrant is unlocked, I asked for him to let me try his AT&T sim card on my phone to validate what I've been reading about the AT&T 3G on the Vibrant.Before he removed his sim card, I asked for him to run the speedtest.net and we registered 1120 & 1080 kbps for Down speed, using the Austin location server. After swapping his sim chip into my phone, with the same Austin server, my Vibrant registered 1785 & 1693 kbps Down. The jaw dropping, blank staring expression on his face was priceless ..I let him played with the Vibrant for a while, he indicated to me a few weeks ago that he was about to upgrade his 3GS to the new iphone 4, but now he's having serious second thought. The old chap wasn't aware of how advanced Android has progressed, and was surprised how much bigger & better the Vibrant's screen is over the iPhone 4 that has been gawking over for the last few months.'ve casually mentioned to him a few weeks ago about the unlocked Vibrant can do both T-Mobile as well as AT&T 3G frequencies, and he brushed me off in disbelief. His sticking point with T-mobile GSM is that it doesn't have the 3G frequency that he needs for his frequent overseas travel. He called me just now to find out where he can get the Vibrant for cheap.

Ive heard some people say that it is not possible for an unlocked AT&T captivate to work on t-mobile because of the differences in UMTS bands.Vibrant:
GSM
850/900/1800/1900
UMTS
2100/1700
Captivate:
GSM
850/900/1800/1900
UMTS
2100/1900/850
My question to the experts though, is if I want to use nothing but voice and SMS / MMS on a prepaid sim with T-Mobile. Can I do this with the captivate? Seriously, the 3g means nothing to me and I have no desire to pay for it, would just like to use voice and SMS / MMS. Will this phone be able to do that at all?

We are an ATT shop and have a user that wants us to get the t-mobile version and unlock for over seas travel. To my understanding both devices have the same 3G bands? it's only in the USA where the ATT and T-Mobile 3G bands are different?

My phone was advertised on ebay as being simlocked to T mobile. However I quickly discovered it wasn't when my Orange Sim worked in it and no T mobile apps or logos appeared on my phone. I already have a Samsung Glaxaxy from Orange so instantly knew that my new phone from ebay was not up to date.As you can see one of my phones is running the latest firmware but the other one isn't AND also says it cannot be updated. What is going on? Has the seller messed with my phone or something?I am not interested in getting Froyo on either of my phones. I will get that when it is officially released. All I want is the ebay phone to be able to be updated. I have tried everything suggested on this forum including changing the product code. I tried to change it on the phone, no product codes were listed as a choice, I also changed the registry but nothing works. Have I got a dud phone because surely my T Mobile phone (which somehow allows an orange sim to work) can get JM3 update by now?
