[Q] Vibrant vs Captivate - Vibrant Q&A, Help & Troubleshooting

I'm travelling to US and wanted to buy a new phone and unlock it. I would like to know which phone do you guys recommend as long as I can unlock it to use with another GSM carrier. Which method to unlock should I use?
Samsung Captivate SGH-i897 Black 3G GSM Smart Phone for AT&T Only or Samsung Vibrant SGH-T959 Black 3G Cell Phone for T-mobile Service Only
Thx

Do this method work?

Well, I can't advise you on the unlocking part, but you'd probably be better off getting a tmo vibrant over the captivate for 2 reasons.
1. Vibrant has froyo officially
2. Vibrant can also get AT&T 3g (though ymmv)

If I flash the phone with a new ROM it will still be locked right?
How do I get the unlocking code with T-mobile?

Yes, I do believe that even if you flash a new ROM over stock the phone will still be locked down to the carrier.
AFAIK, you would have to have been a Tmo customer for a while before you can ask for the unlock code.

If I know someone who is a tmo customer, can he gets me this unlock code?

Theoretically, it might work but I'm not sure if the phone has to match the one your friend has attached to his acct.

I'm running a Vibrant on AT&T. In most cities this works great, though you may lose 3g in cities that don't have the 1900 band. I just used the SGS unlock from Heroz (I think that's correct). It worked great. A person with a T-Mobile account can get you the unlock code as well, though it will take a day or two.

I would check which frequencies the carrier you intend to use the phone with uses, and pick the phone that matches those frequencies better. They are basically the same phone aside from the radios and physical appearance.

[Q] Question about the tmobile vibrant.

Hey guys...
I'm looking into getting a t-mobile vibrant, does anyone know if it works with rogers once its unlocked?
to be more specific, does 3G work?
I've heard some mixed opinions on this and its making me worry. Can anyone confirm whether it works without problems with a rogers sim in it?
thanks.
My guess you could modify the wdcma to work on 3g with Rogers, But remember The roger cell company was originally Rogers ATT
http://en.wikipedia.org/wiki/Rogers_Wireless
Out of the box it will be edge, you will have to go onto the menu and adjust to make it recognize or force 3g on it
BTW I have done this and did get 3g where tmo is not offered but it is not as fast connection less than 1.2 mg at least where I was
thanks oka1
any other ideas?
Ok I guess I'm staying with my captivate =/

[Q] Bell to AT&T

Found a "deal" on a SGSII branded from Bell - I live in the south US and want to know if I throw a ROM (say Cog or a US dev. ROM) or even if I odin back to a factory ROM from an AT&T model - will this work? I cant think of something that would cause this to be an issue & I'm pretty sure it would get rid of the Bell boot up screens or any other branding but I am not 100% on that as I have never taken a out of country phone and attempted to do this before. I'm no noob with flashing but I'm also no developer either so your experience & assistance is appreciated!
(I searched & couldn't find this answered)
You don't need to replace the ROM. If the Bell phone is sim-locked, you'll need the unlock code; there's an unlocker program in one of the other forums that works with the earlier ROMs. IIRC, more recent ROMs have a different unlock mechanism that hasn't been reverse-engineered yet.
You can't replace the Bell ROM with an AT&T one, since AT&T doesn't have one -- no US carrier has released the SGS2 yet. The factory ROM will do the job; I bought a EU SGS2 back in May and have used it on AT&T since then. I get 3G & HSPA+ data at speeds up to 7 Mbps, using an old 3G SIM I've had for several years.

Activating new GSII on T-mobile

Hi guys, I am about to receive a "new" refurb AT&T GSII to use on my T-mobile account. I have not yet received it, so forgive me if this is a stupid question, I just want to be ready for when I get it.
Will I be able to root the phone straight out of the box? I know I need to run the unlocker from the market, but need to root first. Is the phone "locked" like iPhones are out of the box? Thanks!
And also, can I ask what the number 1 recommended ROM is for this phone? I read CM7 has some issues, but are there any CM7 based ROMs that everyone loves?
No, I believe the phone works just fine without a simcard. You should be able to start up odin, flash CWM, and flash a rooted rom all without an active sim card. You can also setup the phone by connecting it to a WiFi network. Once unlocked it will work with your T-Mobile sim.
I don't think the att sgs2 has the radio to work on t-mobile's 3g bands. You'll be limited to edge speeds. If you are ok with that, you should be all set.

Yea, I have no data plan so I'm all good with the incompatible radio. Plus the screen/phone size on the I777 is perfect for me, while the Tmobile one is slightly too big.
I guess I will just follow the guides to root it. Now to pick the best kernel and ROM...

[Q] Unlock Verizon Samsung Galaxy S4

Is it possible to unlock the Verizon version of the S4? I'm deploying in 4 weeks and would like to use my phone with international carriers. I have an SCH-I545 build and I'm still running on stock. Thanks
I think ATT has begun to unlock phones internationally when asked.
Verizon? Not sure... one think to check is if the Verizon GS4 supports a carrier in the country you travel to.
Take a look at Leo Laporte's Tech Guy show... he has callers ask this quetion on average every other week... I think he has show notes on his site now days... techguylabs.com

Verizon phones are unlocked out of the box, but you have to make sure that the country you are going to has a GSM network.
After a lot of searching, I decided to ask this here:
I have a Verizon S4, but I was wondering if it was actually unlocked out-of-box or if there is something I have to do in order to use it with, for instance, Cricket, or U.S. Cellular. I have done lots of rooting/developing for Android, but have never tried to use an Android phone with a differing carrier. Can anyone help or point me to a thread that helps? (Again, did lots of Googling and XDA-searching)

The phone is GSM-unlocked. This means that you buy a SIM, plug it in, then add the proper APN to enable data. (Settings, Connections, More networks, Mobile networks, Access Point Names). The "+" (Add APN) button is disabled if you have a VZ SIM installed but will be enabled if you insert a non-VZ SIM.
Whoever you get the SIM from will tell you what to enter for the APN.
Whether or not it'll work and how fast a network you'll get depends on the bands that the local carrier uses.

HI k1mu,
So do you mean to say if I purchase this device with full price from VZW ~$400 (month to month plan),
the next thing I can do is take off VZW SIM and would it work on my AT&T GSM SIM in US?

Maybe. While the VZW version is GSM-unlocked for international use, it is unclear how well it works with US GSM carriers. Some people say they can get it to work, some say they can't. Theoretically, it should only take you putting in an AT&T SIM then plugging in the APN data for it to work, but some people still say it won't.
So, you should be able to, but going by the accounts of XDA members, it doesn't always work, which may or may not come down to user error.

Thanks joshm.1219,
It still leaves me in a dilemma.. I do really want to get a "S4 mini" model but don't want to stuck up with CDMA providers to be true. Might want to use with ATT or Tmobile or H2O.. I visited the VZW store and the model has option under networks as
1. Global
2. LTE/CDMA
3. GSM/UTMS
Now the Qs are,
1. If this model does have a SIM card slot, how at the first point VZW has lock on it
2. When i asked the VZW associate, he was not sure whether they ever do unlock the device or not
3. If I am ready to pay off complete price of the device which is ~400, what else I would need from them to really 'UNLOCK' it?
4. Is there any means by root/flashing to make such model work for US GSM carriers like H2O or even T-mobile.
Sorry to be so annoying but m new to all these things and quite confused :crying:
many Thx in advance..

Sorry I can't be of more help, I've been on Verizon for 10 years now, but it is by all intents & purposes, fully SIM-unlocked. It's simply unclear as to why some people report problems of using Verizon phones on US GSM carriers. If you really don't want to worry about it & are willing to pay full price, purchase a device through the carrier you want to use it on.
here is the code to choose network
you might need to change the network frequency to gsm if you wanna use it on att or tmobile and when you wanna switch back to verizon choose wcdma try dialing *#*#4636#*#*:good:

I've had people argue with me over this, but the fact is that NO Verizon LTE phone is SIM-locked. None. Nada.
People who claim differently are simply misinformed. (My I545 comes up on AT&T when I plug in my UK SIM and switch to GSM.)
Not to say that all VZ phones are unlocked - my Inc2 had to be unlocked before it would work with that same SIM. If I remember right, it wouldn't connect in the US, either, even after being unlocked. Not so for the GS4.
I appreciate the posts here from people who know. As for me, I am switching to tmobile and will attempt to use this there. If it doesnt work out, I will sell it on swappa and get a nexus 5!
Hi,
Verizon S4 with 4.3 is international unlocked by default.
You just need to select network mode 'GLOBAL'. Then add the right APN.
I am using Indian GSM SIM with the GLOBAL mode selected. All is well for me.
I can provide screenshots if anybody wanna see.
Verizon phones are unlocked out of the box and they DO work fine on US carriers I'm running my Verizon S4 right now on AT&T and I also ran it on tmobile for short time,
even works with Walmart straight talk and Net10 as those are just subsidies of T Mobile and AT&T anyway.
so don't sweat it if you have a verizon phone that uses a sim card, you can run it on any network that uses a SIM card US or international.
baseband issue
Doesn't the MK2 baseband with jb 4.3 block US Sim cards?
Or do I just have a weird s4?

The S4 is supposed to work globally right out of the box, as long as you've called Verizon to enable International roaming on your account. But, used that way, you'll be paying Verizon for International roaming and it's bloody expensive.
The question is, can you remove the SIM and put in a SIM for a local carrier in the foreign country where you are and use the phone on that carrier? That is what being unlocked would allow you to do. Past Verizon phones have not been unlocked to allow this. But, if you called Tech Support and told them you were going to, for example, Europe and wanted to use a local SIM, they would walk you through unlocking (at no charge).
I read a report that the S4 is not locked and that you can use a SIM for a local carrier in Europe, as it comes out of the box. But, I would not trust that. I would call VZW Tech Support and tell them exactly what you want to do - i.e. don't say "can I use my phone in Europe?" The answer to that is yes, you can, at about $1/minute. What you should ask them is, "can I travel to Europe and purchase a SIM from a local carrier and use that in my phone?" If not, they should be able to walk you through unlocking the phone, so you can do that.

to answer your question simply yes.
let's say I take my phone to Spain are somewhere in the UK, I'll go to store buy a SIM card for local network and BAM local phone number in Europe making phone calls, you can even get Data to work if you have that local carrier's APN settings
no unlocking is required because it is not locked.
other companies AT&T, Sprint, t-mobile, yes you have to get The phone sim unlocked.

This is 100% correct. NO LTE phones on verizon are sim locked. They are REQUIRED to keep them unlocked because of their agreement with the FCC for their use of the spectrum they lease. NO OTHER CARRIER must abide by these rules. Only VZW. Sprint I've heard will unlock ANY phone that is capable if you ask them too, and AT&T will NOT unlock any of their phones unless it 2 years old and out of contract (which makes no sense if you have to pay them while under contract anyway). There was a big deal about the Iphone 5 when it came out with LTE for verizon. If you bought a Verizon Iphone, you could put an ATT sim in it and it works, but not an ATT on VZW because ATT keeps them locked.
The Dinc 2 above was NOT an LTE device. Therefore no sim card....and it wouldn't work on most overseas networks anyway as it was a CDMA only phone. I believe VZW tested the limits of the "unlocked" SIM with their first few LTE phones. My Rezound worked with a GSM network sim....but voice and SMS only. It took some unlocking of the bootloader and rooting to run a special Rom to get Data to work on it.
I am heading to the Caribbean in a few weeks, and I will be using a rented SIM card to be able to message back and forth with my wife (with a data based messenger service as data rates are far cheaper than SMS rate there)

I just spent a week in the UK with an ekit.com SIM in my Verizon GS4 - no problem with getting service, no Verizon charge (even though I was on the Vodaphone network for at least some times.)
And the dinc 2, while not LTE, was CDMA/GSM - not just CDMA (yes, the dinc was CDMA-only), so it did accept a SIM card. I'm using that in the GS4 now that it's cut down to micro SIM.
That phone WAS SIM-locked, but VZ happily unlocked it. For the GS4, I didn't have to do anything with VZ to use it off their network.

The phone is already unlocked for SIM and other carriers, all you need is the correct APN for the carrier. I currently have T-Mobile on my i545 and everything works on it.

[Q] Flashing Factory Unlocked/Unlocked S3 to PagePlus

Hello xda,
I'm looking at purchasing a S3 from eBay and I found a seller that is selling a factory unlocked S3. I'm not sure what that really means for me if I want to use the phone on PagePlus. I have a LG Lucid that has 4G capability so I had to reprogram it to use PagePlus on 3G. I never got MMS or data to work on it but that's another story.
Anyway, what does Factory unlocked really mean in terms of flashing? I like that idea of putting any SIM in the phone and using them without a lock is great and useful.
Is it less work to get the phone to use the Verizon/PagePlus network when it's already unlocked?
Also if getting a factory unlocked S3 is the best way to go for my situation, any help getting the phone flashed would be really appreciated.
Thanks

You probably don't have to much more than what you did before on your Lucid, but idk
Page Plus is a Verizon MVNO, and a CDMA carrier. The i9300 will not work, as it is a GSM only phone. If you want a SGSIII on Page Plus, you need to look for the i535 variant. That is the CDMA release of the SGS III.
