[Q] unlocking ? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

i have a friend that is on rogers. if the phone gets unlocked , does that mean it will pick up signals from another carriers tower ? or is unlocking only so you can switch companies and keep the sam phone ?

unlocking just means that you can use other carriers sim cards, the phone will only get signal from the carrier of the sim card you have in

Sprint version: does not disable GSM?

The Sprint version is being advertised as an international phone, and comes with a Sprint SIM card pre-installed, and what appears to be a security strap, making it difficult to remove.
Before traveling internationally, you can call Sprint ahead of time to have them active their SIM card, and for the low low price of $1.99/minute, you can use overseas GSM networks to make phone calls, and in many cases, data access.
Of course I'd like to buy a pay-as-you-go SIM card and install that for much more reasonable rates while overseas, but I'm not sure if it's as simple as plugging in a different SIM card.
I had read that the Rogers version of the phone required...something to active the SIM slot, and even then seemed not to work for data via 3G.
Anybody else have the Sprint version? Played with GSM yet?
I'm a little apprehensive to start tearing into it to remove their SIM card just yet...
The GSM is 2G only, no 3G.
Well my buddy has a AT&T sim card that i put in my TP2 but it did not work. I switch the phone to GSM only but it did not pick up a network. I also put that sprint sim on his phone but it had no network either. According to the manual its lock from going to a gsm network on the USA.

Hopefully a custom ROM can unlock the ability to use GSM networks in the United States!

good to know.
I read in the manual that it was not usable on US GSM networks too, but I assumed that was because they never intended for you to remove the Sprint SIM card, so of course the Sprint SIM card wouldn't work domestically.
So it seems the Sprint phone can be unlocked for GSM just like the Telus phones, but I haven't read of any success getting GSM 3G to work w/ an unlock code.

d'oh, missed this....
What about EDGE?
Check the specs, if it said gsm 850,1900 it should be able to use with in the US. Just have to sim unlock it first in order to use.

What do you mean by unlocked? Do you mean Hardspl or do you mean Sim unlock? If you only dead a hardspl then you can't use another sim. Go here for the sim unlocker
http://forum.xda-developers.com/showthread.php?t=555339
you could try calling t-mobile and seeing if they'll provide the unlock code for you.
Tell them you are going overseas for business and need the device unlocked. This has worked for me with at&t and t-mobile.
I agree it sounds like you didn't sim unlock the phone
come on guys, its obviously SIM unlock if trying a different sim card..
it took my activation number (got it from tmoblie) clearly said the phone was SIM UNLOCKED, then i put the boost sim card, it said "network locked"
i did not try any other card yet, maybe boost sim cards are not supported, but ima test a at&t sim card to see if it works.
I know someone here must of have "NETWORK LOCK" after they SIM unlock there phone, please help me out.

Just my 2 cents for what it is worth. You might want to call boost and see if your sim is locked to an imei #. I know ATT has been using locking sim cards on prepaid for a few months now. Worth a shot
i would say your problem is coming from boost mobile and not from the phone itself... as the person above me mentioned ATT has started locking sims to phones when you buy prepaid sims, not a longshot to assume boost and t-mo will start to do this as well (if they havent already)... or it could be that boost isnt actually a gsm carrier even though it uses sims... not sure about that.
edit: i googled boost mobile technology type and they are owned by sprint... to the best of my knowledge even if you get your GSM phone unlocked it is still not going to accept a sprint (or boost) sim card.
why not, isn't the tmobile one still wcdma and gsm?
like i said... to the best of my knowledge... i never said my knowledge was any good.
can anyone confirm this?
edit: i did some more googling and all the people who asked on yahoo answers and the like got the same answer, no, your boost sim will not work in a GSM phone... i beleive if the tilt 2 were capable of both technologies it would have to have slots for both sims as well..
and to the OP, if you can get a buddy with an ATT sim to try it in the phone this will give us a definitive answer whether or not its the phone or the sim causing problems.
Boost uses the Nextel iDEN network. Although iDEN and GSM both use sim cards they run on different networks. Your Boost sim is incompatible with a T-Mobile TP2. Sorry.

[Q] Is my phone carrier locked?

I have a Galaxy Nexus on SKT here in Korea (not sure how many of you out there are in Korea), but I'm not entirely sure if my phone is carrier locked or not.
I put an old Verizon/Vodafone SIM and KT (another Korean carrier) SIM in the phone, and for about 5 seconds it shows the carrier name, but suddenly goes to "Emergency Calls Only".
I've been reading that for people who are SIM locked, they are asked for an unlock code but putting in either SIM cards did not ask me for that. Does anyone else have this issue when putting in other SIM cards?
No one else here in Korea or can shed some light?
They use WCDMA here, but I know it has the GSM radios in it as well. Could that be a reason I don't get prompted for an unlock code when inserting another SIM?

LG G2 for Sprint gets no love of GSM unlocks

Hello,
So I currently have a Sprint LG G2 that I would like to unlock to be able to use it on AT&T or Tmobile. From what I'v read, even the Verizon G2 comes factory unlocked which Verizon's been known to keep locked in almost all of there phones. I called customer service and told them i would be traveling overseas (they didnt ask what country) and after about 24 hours emailed me asking permission to unlock the device, they told me to go and update me UICC Unlock which gave me a message saying "your SIM is now unlocked" but when I put in a Tmobile sim card to test it, the phone would not recognize it no matter if i changed the settings to gsm/umts or global mode. What do you suggest I do next, I am worried I payed so much for the phone and if 1 or 2 years from now I decide to move carriers or even country that I am visiting to next week and the phone bieng "unlocked" still wont unlock it to be used on local carriers or even abroad, that would really suck. Any suggestions?

You really need to do some serious research.
Concerning Verizon, Verizon is required to have the GSM portion of their CDMA/LTE phones factory unlocked due to to a requirement by the FCC when they divested some spectrum a while back.
Now for Sprint, Sprint locks down (or locks out) the GSM portion of their LTE phones for domestic GSM use, so trying to use it with a domestic GSM carrier like AT&T, T-Mobile etc is out of the question by default. They'll unlock it for international GSM use (non U.S GSM carriers). Now there are some fine folks on XDA here that have been able to work around these restrictions on the Galaxy S4, but that's the exception so far.
If like you say, they emailed you that they've unlocked your phone, if you leave the country and insert a foreign SIM, it'll work with that international carrier.
Your right
your absolutly right. Now i need to find out how they did it in s4 because it has to be possible for this phone too then that case

Hmmm, this is interesting, I am having a similar dilema, as far as I was aware, I thought that unlocking would be done on the cosumer end, they would give you a code, then you'd input that code in, I've just never heard of them unlocking it on their own. I got the LG G2 LS980 when I was in the US for a semester and moved to Brazil just a week ago, I haven't tried to fully make it work, but from the LS980 manual, it says that there is not even a sim lock on the phone(i'd put up a picture, but I have no idea how). And when I try to put in an old local(brazilian) SIM card, it doesn't ask for a unlock code, it just says no SIM card - Emergency calls only. I'm still researching it, but if you find anything, just post it here so I can keep up Thanks.

Yeah I will definitely have to wait for a workaround for the sprint LG G2 as I am not a sprint customer. I think the S4 and the HTC both have workarounds, but as far as I'm aware, these workarounds apply mostly for international use only (which is exactly what I need) meaning that ATT/TMOB is probably not going to work, or might have to wait a couple months until there is a lot more people working on the sprint version, the thing is, the phone wasn't released that long ago, so support in the forums is still low.
Back during the photon days they were able to achieve domestic gsm use by flashing the radio from the Japanese version of the photon. Well maybe not directly. It may have been a modified Japanese radio but it worked!! My daughters mother still uses the photon 4g as an att go phone. Would something like that still be possible for our devices? I know a lot of people lost interest in it because after the photon we got the photon q which had an embedded Sim. Even then people were able to take the phone apart and solder a Sim tray in and unlock it for other domestic carriers.

But I think first of all it needs to be unlocked for GSM or GSM part of the phone should be unlocked for any other thing to try.

As long as some foreign carrier has their g2 unlocked for international gsm use then it wouldn't matter right? With the KDDI radio on the photon we weren't able to use sprint service on it after flashing. Basically as if the phone thought it was the Japanese version of the photon.

This would be awesome if it worked, I'm still hopeful someone will find a way, because I don't use sprint anymore and I have since moved to brazil. Thank god this phone is awesome enough to not be useless with only wifi, but I'm still hopeful someone will find a way for me to catch Brazil's GSM signal, as the phone does have the right GSM bands for it.
Just like the HTC one, it took months for even Sprint themselves to figure out how they would unlock the HTC, what I want to know if there is anyone that has actually called Sprint and asked for the unlock, and confirmed it to be working.
Can the sprint lg g2 be unlocked for any carrier.
Im trying to change from sprint contract to straighttalk. Is there a way to get my LG G2 unlocked so I can switch?

I unlocked my GS2 Skyrocket recently as I'm about to sell it and pick up a G2 next week. I popped in a T-Mobile SIM and verified that it worked. However, I very seriously doubt the method I used would work on the G2. Here's the thread though:
unlock free proceed at your own risk!
Domestic sims are too small

I called the Sprint international department and they explained the situation somewhat.
Domestic sim cards such as on tmobile and att have too little memory to support the cdma function of the lg g2, so you will get an "invalid sim" message. The size of the sim must be at least 128k to work on the g2. Maybe there is a way to get domestic network data on a larger sim card.
Hope this helps.

while the size thing may be true.. this is not why youre getting an invalid sim error. the invalid sim error comes from when u use ANY sim thats not Sprint. After you get Sprint to OTA SIM unlock your phone.. this invalid sim error goes away... gsm will work for intl.. and possibly domestic.. tho sprint may also have a block on domestic only.. after the intl unlock. if the phone is unlocked thru sprint and you pop a tmo sim in and get no signal(but no invalid sim error)... then that means the phone is unlocked properly but domestic is blocked.
this is usually my area of interest.. i did both the htc one and gs4 unlocks but I do not own a g2 unfortunately.

So are you saying if you did have a Sprint G2 you would be able to find a way to unlock it?
How the heck do they do this?
How can they unlock the phone for international SIMs and prevent them from working on local SIMs? Can't be some band that they check. Otherwise, it would not work on an international SIM using that band. Hardcode something in the kernel or the OS? In which would a custom ROM and/or kernel work? Can anyone point me to some links or posts that discuss this?

I'm also interested in this as I have a LS980 and I am currently in Brazil, sprint has done nothing yet as far as unlocking it.(even for actualy customers, I have not seen anyone that actually has this thing unlocked). I popped in a Claro(local provider) SIM card, and the phone says "No SIM card- Emergency calls only", I've tried multiple SIMs to see if it was a problem with the actual SIM, but all of them read the same thing, while inside the phone I get a notification saying "Restricted Access Changed - Voice Service is Blocked". So it knows there is a SIM card in there, it's just blocking it.

cant be 100% certain... but I'd say there'd be a good chance. Unlocked another Sprint phone this week.

dual sim

hey guys I am looking to purchase a note ten plus and was wondering if the dual sim feature would work with two different carriers, both carriers are on gsm networks.
Yes it will.
Just make sure it's unlocked and not from a ISP/services provider.
If it comes from a Telco (vodafone/O2 and other) they are software restricted to 1 SIM. You can reflash with an unlocked software (general 975F firmware and it would unlock SIM management but the telco would or should have the 2nd SIM locked.
AFAIK there isn't a sensible way to unlock a 2nd SIM for an officially single SIM device, though it Should be possible.
