[Q] Does the SII International will work on 3G/4G on T-Mobile

Sorry, I know this must have been asked before, just couldn't find the answer.
Want to buy a S2 (tonight!), but was wondering if it will work with TMobile's 3G or even 4G.
I use TMobile plan, and would like to switch to a non-contracted S2, but wants to enjoy AT LEAST 3G speeds (willing to sacrifice 4G).
So - please help
THANK YOU!

As far as I know you will not get T-Mobile 3g because the international version does not support their bands for 3g
Just edge (no 1700mhz aws band). Galaxy nexus will...

how to check galaxy s3 is 4g-LTE activated or not?

Hi... How to check if my galaxy s3 is activated for 4g-LTE network as in the country I work right now dont have 4g-LTE but it is going to launch the 4G-LTE in few months...
Unless you bought yours in Korea and it has more angular shape like the S2, I doubt you own an LTE version.
It hasn't been launched outside Korea.

Pretty sure the LTE models only have dual core processors in them.

USA LTE variants come with dual core
Korean LTE variant come with quad core
And both have 2Gb ram

It its model (Menu --> Settings --> About Device --> Model number) is GT-I9300, it's the international version and it's not an LTE device.
If it's SGH-T999, it's the US T-Mobile version, you're in the wrong forums, and it's not an LTE device also.
If it's SGH-I747, it's the US AT&T version, you're in the wrong forums, and it's LTE-enabled.
If it's SCH-R530, SCH-I535 or SPH-L710, it's one of the US CDMA versions, you're in the wrong forums, and it's LTE-enabled.
If it's SGH-N064 (SC-06D), it is the Japanese NTT DoCoMo version, you're in the wrong forums, and it's LTE-enabled.
Finally, if it's SHV-E210K/L/S, it is the Korean version, which is the only quad-core, 2GB, LTE-enabled model. And you're in the wrong forums.
I have international version..

If you have the i9300 than you only have HSPA+.. no LTE.. but its still 4G..(more like 3.5G to be technical) Now if you lived in the Korean market and manage to get your hands on a LTE version then you have LTE where the bands are supported..

Thanks I have international and I can receive H+
anyone seeen me?
I just got thebsprin gs3 4g lte model and I too want to know how can we manually turn 4g on or off or simply verify it's on 4g. My epic 4g had a friggin checkbox you could see it was checked or jot but the gs3 doesn't. Still love the phone so far with one major hit, no ability to kove apps to SD. Is it just ke or does that seem stupid? Anyone know of abway to get this functionality back without rooting and if rooting is needed what's the likelihood I'll brick my phone? Never rooted, scares me
Easy way to check is to use the speed test app, if you get more than 40mbs, there's a good chance that you're on a lte network with lte access. One of my mates has an i9300 GT, 1G ram but gets 54mbs, so I'm at a loss as to what's going on there. I did the speed test for him on Telstra's network in Tassie... Checked in settings and it does use lte...

I hv Korean s3 SHV-E210 L 2GB RAM and 25GB ROM and it only connects to GPRS and 3G!
I have Korean s3 SHV-E210 L and it only connects to GPRS and 3G. When I select WCDMA only the network keeps on dropping out. Please tell me whether my phone is 4g compatible? I even do not get H+ network in this phone. I had s2 and it was having a great H+ network but this s3 only receives 3g forcefully. It has got 4.1.2 custom , 2GB RAM and 25 GB ROM. And can I upgrade it to kitkat?
I am sick of slow internet please help. Thanks admin n all.
Thanks.
The E210L is not a good match for either European or American bands, as it's tailored to LG U+'s CDMA (3GPP2)-based network. It is a bit of a surprise that it even works on GSM, much less on 3G.
IIRC the E210K is recommended in Europe.

I am in India and using Korean s3 LTE 2gb ram which doesn't receive H, H+. It only catches GPRS and forcefully 3G with an speed of maximum 1 mbps. I have contacted Telecom provider and am sure it's not there fault as apart from this phone other phones work perfectly fine. Please help me to improve the speed of my cell data internet as it can support Upton 21mbps. I am sick of slow internet and network dropouts. Thanks. ?
AFAIK India uses the same frequencies as Europe (same ITU region). So, you will likely need E210K or E210S (both GSM devices) to get 3g and 4g, not E210L, which is a CDMA phone. Not all Korean 4G S3s are the same.
Also, your SIM could be too old, or your APN settings wrong. However, it sounds like your device can only receive a less-used frequency band for 3g, with less than normal coverage - a common issue with LG U+ devices.

S3 Network issue! Slow internet!
I've S3 E210 L and when I check my APN settings it does have LTE option under Bearer but currently my Telecom provider doesn't support 4g. However they do provide 3G with a great speed. I hv used it on other mobiles and it works great . It's just this phone gets only G when selected GSM/WCDMA automode. When I manually select WCDMA only it gets 3G but very slow speed and it drops out very frequently. The maximum speed which I have received is around 1 mbps only.
Please provide me with a resolution how I can I get good bandwith/speed. ?

[Q] China MTK6577 Phone AT&T settings

I picked up a China Clone S3 running the dual core MTK6577. It works quite well and I am satisfied with the build, but I can't get it to lock on to my AT&T 3G signal. It grabs the 2G Edge signal just fine but not the 3G.
Anyone have the APN settings for AT&T to get the 3G to work?
Thanks in advance.

Did you make sure the phone used the same bands ATT does? I bet you issue is the hardware is not made to use that band. If that is the case them edge is the best you will get

No Signal!

I am running @epicboy 's CM11 build. I am in Ghana, west Africa and we don't have T-mobile here. The device is unlocked but interestingly, only one mobile network here works with the phone. And even that only gives me an edge connection. Is there some kind of modem I can flash ? Or is der a hardware fix I can try? Thanks
That depends on the band of the network you're trying to use and the bands that the phone has. The network I use here in Jamaica only only gives me edge but the other network allows me to use 3g because they support the 3g band that the vibrant has. There isn't anthing you can do about it to my knowledge and even if you can do something (I think) it won't be much or make a huge difference.

SHV-E160S 3G Locked

Hi Guys !
I have SHV-E160S 4G LTE (Korean), and 4G is not available in our city. I want to use 3G.
Whenever I go to Mobile Data Settings and there are two options
(1) 2G & 3G
(2)4G LTE
As I have told you guys I have no 4G but 3G coverage is available. I check the first option but yet the phone keeps on running on 2G, I've heard that these korean SHV-E160s are 3G locked. One of my friend has a SHV-E160L (Also korean) and 3G works perfect on his phone.
Please tell me some way to unlock or use 3G.
P.S. My phone is rooted, using KINGOROOT App
Please help :crying::crying:
please dont ignore.. help!!!
