[Q] Will this phone work on 3g in Europe & UK ?

I bought my SII a few days ago and am wondering if it will work in Europe.
Also, will t-mobile give me an unlock code? I've been with them for over a year.

I got an unlock code for mine and i have only been back with tmobile for 60 days. Just ask them in chat. It will work in Europe but I don't think it will be on hi speed network.

How quick did you get the code? I just called in and made the request. She said up to 14 days.
I think Europe 3g band is 2100 which the t-mobs SII supports. But I don't know if that means it will work.

Yes it will work on 3G in Europe... I've taken TMO phones to Spain several times and was rocking 3G on Vodafone the entire time.

if it has the frequency it will work

Awesome, thanks guys.
Tmobile just sent me the unlock code. Is there any way to enter it without another sim card?

Could 1 of you guys request the Unlock code for my Galaxy S II? I don't have t-mobile, I brought the phone from a 3rd party phone shop. I have a receipt from the shop, but I'm assuming t-mobile wants a receipt that it was purchased from them. PM me if someone will help me pls.

No the new sim card has to be in the phone every time.When you used different sim card the code is the same .I travel to Poland a lot and other countries and I got the code like 4 years ago and it sill works all over europe and 3g works too

It's not possible to do this for you, need TMo SIM, they check it.
You can pay one of those services a small amount of money for a code. It's fast and less hassle than trying to get TMo to give you one.

That's not what I meant. I'm asking how can I enter the unlock code? T-mobile said the only way is to put in a non-tmobile sim card and then it will prompt for it.

actually there's a USSD code to make it pop up, without the need of a SIM card
check out the Galaxy S wiki pages in XDA

Exactly what I was looking for. Thanks dude.

[Q] Is T989 working in UK's networks?
The spec of T989 is a lot better then T9100! I wonder if T989 is capable working in the UK network. If so, I am going to get one on Ebay! Thanks!

At&t Sim Unlock Debacle

I need some help. At&t won't unlock the Sim claiming "exclusivity" although this device is released by every provider known to man. Anyways, the voodoo sim unlock app for the international S3 is not compatible yet for the At&t 747. What should I do? I need to use straight talk and would like to be able to use t mobiles network. Should I return it or wing it? Anyone been in this position before? Does anyone have any info on whether voodoo app developer can or is working on building an unlock app for US versions?

How long did it take for you to get your code? I just processed an order with them.

done, unlocked. now i need some t mobile hspa radio's to flash.

Hey when I enter the *# code to see if my ATT GS3 is locked I don't get that screen that pops up on the vid showing its locked. How can I tell the phone is locked to ATT?
Thanks

U check by putting a non att sim in. It will ask for unlock code. You dial *#06# to bring up your phones IMEI number not to check if its locked.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

Well there was a video on the website that had a *# code to show if your phone was locked, so I tried that and got nothing so maybe I need a dif SIM other than the ATT one

yea i think it only works on international one. doesnt work on mine either

Ummm... Straight Talk uses AT&T's network. You don't need to unlock the phone to use it with them.
Edit: you're using it with ST's T-Mo sim? Why?

root it, then go here. id stay away from direct patching, but it shouldnt harm by plugging it in, reading the nvram.bin and generating a code

I was wondering the same thing. I thought I read you could use either an Att phone or a TMO phone on straight talk with their sims. Also in the TMO GS2 threads there are people saying they didn't even need an unlock code to use the GS2 on straight talk. I've never used Att or TMO but I'm taking a close look at straight talk. In general is it true Att has better coverage than TMO? I know they are both better than Sprint.

Would be great, if the required nv_data.bin file was actually in efs like in the international version, i checked for the file in /efs and it doesnt exit.

Same here.

There's differences in coverage. T mobile more hspa speed 6-7 mb/s, at&t 2-4 mb/s. At&t has more coverage overall coverage tho.
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

But the AT&T version can't run on T-Mobile's bands. Nobody even knows if it will eventually be able to, either. Until then, you're not even going to get 3G

Well,bought the unlock code from cellunlocker instead,well see how it goes.I want to use the att version on the Rogers network.

Got the unlock code works fine,now using the att cersion on rogers's 4G network !

Thanks for the info on the two networks. I am thinking about waiting for the next GSM unlocked Nexus phone and running that on a prepaid plan that uses TMO or ATT's network. Hopefully we'll see one before the holidays.

How many times can you put in wrong unlock code?

Hi Guys,
So I've searched and can't find anything on this. I am going overseas and T-Mobile has given me an unlock code. But every time I put it in I would get "unlock request unsuccessful." I've called them four times and they don't seem to know what they are doing and just tells me they will escalate the ticket. I have tried the code two or three times. I was just wondering how many times can I try it? I've heard that it can permanently lock my phone. Thanks in advance.

First of, are u using a different carrier simcard before inputting the code?

At first I tried dialing #7465625*638*# and then putting in the code but that didn't work. I had a SIM from oversea so I tried that and it didn't ask for an unlock code. It just says invalid SIM. My friend has a Verizon S3 which has a SIM so I tried his SIM and it says invalid SIM also. I don't have any other SIM to try and I'm worried that I'll get oversea and it'll do the same thing with another one of their SIM.

Ok, coz most of the time people doesnt know that you have to use a diff simcard. Have you check to make sure the imei number that tmo had in file matches the one on your phone?

Yea, every time I called them I give them my IMEI and they read it back to me correctly. The email they sent me that has the unlock code has my number and my IMEI and it's all correct. I'm not sure what else to try. I thought about just going through cellunlocker.net but what if they give me the same unlock code as T-Mobile? Does the non-carrier SIM card have to be active and in service? I was thinking that the guy at Verizon told my friend that his SIM was only used for 4g data and the foreign SIM I have wouldn't have any service here. Maybe that's why it's not popping up with the unlock code screen?
I forgot to mention that my phone is rooted. Would that have any affect? Would it be a good idea to flash the phone back to stock and try to unlock?

I went to the T-Mobile store and the guy told me he has never done an unlock before and he doesn't know what to do. He told me I should call T-Mobile again. I will be oversea for about two years so I was just hoping to be able to keep this phone since I've only had it for a couple of months. But I guess if it won't unlock then I'll just have to get a new phone. Anyway, thanks for the all the input guys.

Is a direct unlock the same thing as what they are doing with Sprint and Verizon with the nv_data.bin? I was going to do that and then I saw that T-Mobile doesn't have the nv_data file for some reason.

Do you have the i747 or t999? Was the code entered using a custom ROM?

[Q} Network unlock?

Does anyone know if any of the usual unlockers (e.g. cellunlocker.net) has the unlock codes yet? Or if there are different unlocking methods? Thanks!

I hope something comes up soon. I purchased full price and AT&T won't unlock.

Any issues with this unlock? Are they permanent? I know customer service reps are clueless half the time but when I called to get my unlock code and was told I was also told I should be careful of getting an unlock code online as he had a case of someone call once saying their unlock code only worked with the phone for 90 days and then it stopped working (not sure if the phone or the unlocking). Also, any issues with privacy in regards to giving out en IMEI number?

Appreciate it.

same here. got it from cellunlocker and used the phone in switzerland without an issue.

My phone is I317M that locked to Canada Rogers Network. I messed up my phone once due to flashed 7100 rom to my I317m, and I lost all information like baseband, network, imei. After did some research, I flashed a rogers stock rom back to my phone, and my phone get fixed and got signal again. Noticed that my phone is even unlocked. I dont know how that happened, but my phone works with other carrier now. Expect if someone can explan this.

This is reported by quite a few to be working and best of all it's free I tried it but don't have a sim for another carrier but I haven't gotten any errors and my phone is still working.

I actually just bought the unlock code today from cellunlocker.net (but I haven't actually used it yet) and then I see this thread and was just going to try the method from your link for ****s and giggles and it WORKED! what a waste of $25

If you ever travel overseas, you can just buy a prepaid sim and stick it in your phone and you could use your phone while traveling for cheap without paying any carrier roaming fees.

I don't want to pay for a DATA PLAN!
So check this out.... I am an AT&T user and back when the HTC HD2 came out for T-Mobile I bought it from a friend when they signed up for a new contract. Got an unlock code from Ebay and have been using it for the past 2 years without having to have a data plan, never got added automatically to my plan like i have heard happen to others? And I'm wondering why? Is it possibly cuz its a T-Mobile phone? Or is it cuz I still have an old "Cingular" SIM card? I am curious about this because right now, Wally World has a special sale on the phone at $249, plus a $100 gift card, which will bring the phone down to $150 basically, so a pretty damn good deal for a phone just out on the market. And I'm plan on getting it this week, I was wondering if any of you would be able to tell me if at some point if i was able to get a T-Mobile version of the Samsung Note 2 if i could slip my SIM card into it and then be able to cancel my DATA plan, if i told them i went back to a Motorola Razr or something, which worked when i got my HD2? Or will AT&T be able to see that i have a smartphone? Is it the newer smaller SIM card, that will tell AT&T that I have a smartphone, or will the phone it self be what sends info to the servers or whatever that tells AT&T I have a smartphone? Or do you think this method of getting a T-Mobile phone and using an AT&T SIM card will work and I won't get stuck with a DATA plan? Everywhere I go has Wi-Fi so I have no need for the Data plan it will be going to waste.

[Q] Unlock code (sent from T-Mobile) does not work

To anyone who doesn't mind helping out,
I purchased a T-Mobile T-889 Samsung Galaxy Note II (4.1.2 Jellybean out of the box) brand new. I've had the phone for 47 days (I bought the phone on 4-9-13). T-Mobile made me wait 40 days (maintaining active account status) before sending me an unlock code. The unlock code they sent me was "07319707"
I did exactly as stated and the message keeps coming up "Network Unlock Unsuccessful". I've called T-Mobile 3 times since I received the code and all they do is escalate the problem to someone else but no one has e-mailed or called me back since. They told me if I try to enter it more than once that it might cause a problem which was after I had tried several times to do it.
I am fully aware of ppl buying unlock codes online and that if you have 4.1.2 that you must go back to 4.1.1 in order for the old code to work but I'm trying to avoid that.
If anyone has any suggestions / advice I would truly be grateful.
I am attaching a screenshot of the email from T-Mobile.
Thank You

I think the best option here is to work with t-mobile support and get it resolved.
I have always found the online chat support much more helpful than their phone support, give it a shot and hopefully this will get resolved.:thumbup:

Phone can be unlocked with an inactive sim. Just make sure you are using non t-mobile sim.
If the phone accepts the unlock code then it's unlocked but it wont show network on an inactive sim.

*status update* I spoke with T-Mobile today. They are emailing me another code...should be in my inbox by tomorrow. They also said that Wi-Fi must be turned off. I don't remember if I did that or not so that might have been an issue.
*GT-N7100*
For anyone reading this that has a GT-N7100 International Note II (my first one) who lives in South Florida (Palm Beach / Broward Counties) I found out today that I threw my money out of the window when I bought the T-Mobile Note II. Either T-Mobile is done or almost finished re-farming the 1900 MHz band down here and I was able to use my T-Mobile sim in the GT-N7100 that I own and able to average about 10mbps download on T-Mobile's network (4 more than AT&T). Around early April I tried using a T-Mobile sim (changed the settings properly) in the n7100 and couldn't even get 1 mbps download. I did not believe T-Mobile would go through with the re-farming in south florida because believe it or not we are not a top 10 market. For those of you who have an unlocked AT&T branded Note II who is still on AT&T... I strongly suggest you either try straight talk or T-Mobile itself and try to use the phone on T-Mobiles network...(Do you really need LTE when it's possible to get 14 to 15 mbps download w/o it?) For what AT&T charges for their service they are straight up ripping people off.
