While I was working in Korea, I bought a Galaxy s3 SHV-E210 (Korean Model) cell phone. When I bought, I was told that I would be able to use it over here in the States. AT&T was able to put a sim card and activate it on their network, however I only get 3G. The Sales rep told me that the bands for 4G/LTE are different in Korea than stateside carriers, so I may, or may not pick up 4G/LTE. I've done some research and found that the band in the phone can be changed using certain codes. When I enter *#9090# it brings up a menu, I've tried changing some of the 4G/LTE, 3G options in that menu but I never get 4G. I know how to root and put custom firmware on devices, so if that is something I need to do then I am comfortable with that. Can this phone be changed to get a 4G/LTE signal? are there any more "codes" that I can enter in to get any other options that will help me? has anyone here ever change the band on their phone to work on 4g? Thank you for any and all help.
AT&T uses LTE band 1 for service.
since E210S only supports band 3 and 5, and 3 and 8 for E210K, there's no way to access AT&T LTE network with your device.
It is reported to support band 1 for newer devices like S5 and G3 and AT&T LTE devices might work in Korea since May 2014,
LTE won't be available with Korean S3 in US.

I recently took my phone to the UK, and it seems to get no signal at all. When I do the *#*#4636#*#* service menu, it only states that it has usa bands (my captivate and nexus one had multiple bands to choose from). Does anyone know of a workaround to get this phone working overseas?
Called AT&T and they were no help in getting the phone connected.

AT&T does that **** on purpose because they want you to pay for their international plan...if you talk to them about it, they'll tell you that you need to sign up for a plan that will let you go out of the US with signal.. (it's not permanent, but you pay for the month that you are gone).
Problem is I already have the international roaming plan.
If you're trying to use a foreign simcard it wont work unless you have a sim unlock code.
Otherwise there is no reason it shouldnt work overseas on your ATT sim card if you have the right plan. it has the correct 3g bands to work anywhere in UK/EU on 3g.
It could be that its not pulling down the right APN settings for orange or whatever provider its trying to roam on. Just a thought.
Just out of curiosity where in the UK were you? I was there in Dec with my AT&T Blackberry (worked fine) and will be there in June with my BB and my Atrix (didn't have a personal international phone when I was there in Dec as I had been on Sprint at the time). In the past I've had no problems - taken past AT&T phones to Germany, France, Spain, Scotland, Slovenia and Italy and they've always worked (that was with my old HTC Fuze which I had totally unlocked). The only place I ever had a problem was rural Wyoming about 100 miles west of Sturgis two summers ago. It wouldn't work but for one corner of the driveway at the cabin we were staying at.
I have been in London. I actually brought my samsung captivate, and put my at&t sim card, and everything worked just fine. If I place my sim card back in the atrix it looks as if it does not detect the signal at all.

Hi. I know where you can work that phone overseas. Kindly contact me.
Groupon has a deal for the S5 that says it's for "Verizon and GSM Unlocked":
https://www.groupon.com/deals/gg-samsung-galaxy-s5-smartphones
Is there any way to tell what model # this is? I'm guessing that it is a generic S5 and not the T-Mobile specific SM-G900T. If that's true, then it likely doesn't have the TMo specific LTE frequencies needed for full service (I'm in the Chicago area), correct?
I really hate having to find special versions of GSM devices to make full use of T-Mobile's network...
<TAP><TAP> Is this thing on???
Unlocked for all Verizon and GSM carriers.
On the same page --> https://www.groupon.com/pages/groupon-deal-images-gg-gsm-providers
Only thing is that it probably will not be compatible with WiFi calling features, but I could be wrong.
I know it would work but I was curious about whether it was the same model they sell via T-Mobile that has their unique frequency bands (1900/2100 I believe). Groupon responded to an inquiry and said it was a Verizon model so while I can't confirm it, I'm guessing it doesn't have the extra bands needed to fully make use of T-Mobile's LTE network so it would likely drop down to HPDPA+ in many locations.
According to the reviews, its a Verizon branded phone. A couple of the reviews are from T-mo users and they claimed to have issues with the sim/network not going to LTE, instead it uses their HSPA network.
If it was me, I would not buy this. It is cheap yea, but remember that the S5 is not compatible with the new band 12.
-edit-
The Chicago area isn't getting band 12 anyways, not anytime soon that is.
I'm using a Verizon S5 with a T-mobile rom and it works perfect 4g lte and all If you end up getting it just root it then look at my view forum posts.
Has anyone been able to access Service Mode on the X Mini (or some other Asus phone)?
I have an unlocked X Mini that I'm trying to make work on a local Wireless provider (GCI), and I've successfully rooted the phone using the primary technique already described on this forum. After putting in my sim card all I get is a small 'x' next to the signal bars. I was able to get the phone to work with an AT&T sim just fine, and I've been able to get another AT&T phone (Galaxy S4) to work after changing frequency band. GCI uses 850 and 1900 for 2G/3G and Band 4 for LTE. AT&T phones also use those bands, so I should be able to configure the frequency bands accordingly. Unfortunately, most of the solutions I've seen on the interwebs are geared toward more common Android phones.

Code:
*#*#4636#*#*
The 4636 option gets me to a potentially useful menu, but what I'm looking for is more like the *#2263# menu that allows for setting frequency preferences. I've successfully used this menu on a Galaxy S4, and now I'm looking for something similar on the X Mini.
No one else has had a problem connecting this phone to a non-AT&T network?
I have mine unlocked also..and it connects fine with T-Mobile on my end...
T-Mobile US here. I just got my AT&T unlock code today and successfully unlocked. There's no non-LTE service where I live, and sure enough, I have no service. I found a thread on using some Qualcomm tools to change the bands used by the modem, so I may try that.
Hi there, i was able to get one of these from a local walmart for about $150 bucks, its a Verizon Prepaid samsung Galaxy S4 i545PP i545ppvruaoh7 is the build, and it comes with lolipop.
the reason why i bought is is because according to http://willmyphonework.net/
this phone was supposed to support 4G LTE Band4-AWS , but it does not!
it sure comes unlocked, i can put any sim card and i get signal, i get 2g, 3g, H, H+
I tried different sim cards and the best it can do is H+ on all of them.
I tried changing it to global, and also changing it to LTE GSM etc on the android menu but i have no luck.
Is there any way to enable the 4G on this phone? I live in a contry where all carriers use the same 3G and 4G that At&T uses. So here all At&T phones got 2g, 3g,and 4g out of the box. And i thought this verizon phone supported 4G Band4.

Are you sure ATT uses band 4 (AWS - 1700/2100) in your area? ATT uses a number of different LTE bands in different areas, and the Verizon S4 (prepaid or not) only supports band 4.
im sure my carrier uses same band as At&T, 100% positive that my carrier uses Band 4.
reason is because i also bought two other phones, a moto E At&T gophone and i unlocked it and i got 4G icon at first boot with the carrier here.
but verizon galaxy S4 prepaid is different, i can´t get more than H+, i have never seen the 4G icon
and i dont think there is a hack for it to enable all bands
Hi guys,
I rooted the phone, installed audio and viper mod... but the only reason I even got that far was trying to root the phone to get additional bands added to the modem. Seems like I am not getting far lol.
The ulefone power 3s I got does not work in canada for bell... as it lacks 3g apparently and only has 2g and 4g? 4g data works, calling phone with 2g works. So data works for bell mobility and rogers, but voice and sms does not work with bell mobility... only with rogers/fido/koodo.
I am going to switch to rogers from bell due to better cost (45 a month plan with data) vs 80+ with bell... so ill get voice working but im worried then how much this phone will work when roaming in the states and what have you....
I seem to be only able to find how to edit bands with qualcom based phones but ours is a p23 or mtk 6763 processor phone.
Did you figure this out?
Just wondering if you were ever able to unlock the bands. I am having a similar issue
Fault of the smartphone made in mediatek：
The japan domestic carrier company where iPhone is set to use all of carrier bands in Japan merely hangs SIM lock and sells a terminal, but even which carrier is available if I cancel it.
However, there is no human being who wants to use this even if the phone which is how much which is the phone which is usable only in Japanese Tokyo where only a measure band of 3G and the LTE is usable because it is sold domestically without most of the carrier bands in Japan being available is bargain as for the smartphone made in mediatek
Even if the person buying it appears if baseband sets it freely and can add it, such an application does not exist.
Because I get the root right, in z3c of sony where band addition is possible freely by QPST and QXDM if it is a phone of snapdragon, there are still many users
The smartphone made in mediatek is a really useless (not smart) phone in Japan
