Hi guys.
I didn't know where to post and I have few questions on my Galaxy SII I bought from Korea and brought to USA.
I have KT's 250S galaxy SII and I'm trying to use it for At&t. I tried to put my At&t sim card in and looks like it is getting some connection. I was able to make a call.
However, looks like it's not getting any 3G connections. I heard there is some modification on the network I need to change to get 3G. Could you please let me know what should I do?
Thank you,
Andy

Go to the miui thread in development section and use the apn from there. That should theoretically fix your issue...

There is nothing you can do.

From the third post down:
Code:
<< Korea Galaxy S2 Network support >>
Double band UMTS 900/2100
Triple band GSM 900/1800/1900
<< EU Galaxy S2 band Network support>>
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
AT&T and International (I9100) GSIIs support the same bands, which is why I9100s work perfectly in the US. Your device is completely missing support for the 850 MHz band (first device I've seen in years that wasn't quadband GSM other than dumbphones) and also missing support for 3G in the 1800 MHz band.
So you will not have 3G coverage anywhere, and you will completely lose coverage where AT&T uses the 850 MHz band.
Hello All,
Has anyone had any luck getting a Huawei U8860 to work on T-Mobile in the US?
Here are the details on the phone:
It was a Chinese model that I upgraded to the worldwide Android 2.3 ROM from the huawei site.
I have voice and 2G Edge Data working, but I can't get 3G.
It is a quad-band (GSM 850/900/1800/1900) device.
The phone says it supports 3GGPRS, HSPA and WCDMA. I also read a CNET review where they were unable to get 3G and were limited to 2G Edge.
Has anyone had any luck with this device in the US? T-Mobile or AT&T?
Thanks
3g connectivity
I am in South America, and I am experiencing the same problem. No 3G connection! Please help!!
So far I've tried two officicial ROMs (2.3 and 4.0) withou luck. In fact, I was hoping that the problem was fixed with the new official ROM released today, but I am still getting just EDGE connectivity.
Help!!
I think the problem is the radios on the phone. I did more reading, and it appears that it does not support the HSPA frequencies, so it cannot do 3G in the US. Apparently, the only penta-band phone that does 3G world wide is the Galaxy Nexus. Oh well, the phone is still usable, I just have to suffer through 2G speeds.
Hi,
Recently I happen to move to India from USA. I had Samsung Galaxy S3 - SGH i747 purchased in in US, which was under 2 year contract. I tried to call AT&T guys to give me unlock code but they didn't give me since my contract was not over.
I moved to India and tried to unlock my phone from local shop. I am able to make/receive calls now having these issues.
1. 3G is not working . When I see different available bands in my phone using *#2263#, it shows WCDMA 850, 900, 1700, 1900 and WCDMS IMT2000 under WCDMA band preferences. I am using Vodafone in India which runs on UMTS 2100. I visited Vodafone store couple of times but they are not able to help me. How do I get 2100 frequency in my phone ?
2. Currently I have set preference to run my phone on GSM Band so 2G is working. There are certain areas in my city where Vodafone 2G is also not working. In those areas, I don't receive any call even though I have very good network coverage. I tried switching off my mobile network in case I can receive calls but its of no help.
Request for your to resolve this. I am fed up with this nice working phone and need to purchase new one if these issues don't get resolved.
Thanks
Hi need help please , I have a Galaxy S4 I545 Verizon to buy in Spain , apparently to be used , the store bought it from someone who originally bought in the United States. And only I can connect on 3G and even in the back of the device says s4 verizon 4g lte . When I change the LTE network goes without service. Let alone globally connect on 3G, I wonder if I can enable or install 4G LTE bands . Now I live in Sweden and have no lte since only 700 US that band is used. Thank you
Evening all,
Just a bit of advice, I'm looking to upgrade from my g8x to the v60. As the european/international version is virtually impossible to find, I'm looking at the unlocked USA variants of this phone. Does anyone have this model in the UK and can confirm that it works on 3g/4g OK? I've found different sources stating that some of the bands aren't present in the USA variants - not bothered about 5g, just as long as I can get 3 and 4g on o2 it's fine. Also tried frequency checker but it doesn't seem to list the v60 on there for some reason...
OK so I've just come across the website Kimovil, this seems to be more helpful - looks like the only one that is going to be any use is the Canadian variant of the phone, the USA versions from t mobile/at+t have most of the bands missing for use in the UK. Explains why they go for far less online!
Interesting have you got a link to that site or have a link of where to buy one that will be good for UK
Also looking to buy a v60 to use on the UK
Kimovil.com
Not really found anything other than links for the USA versions of the phone, they don't seem to have the correct bands for most of the UK networks. I'm just watching eBay and seeing what comes up...
I bought an ATT model, unlocked from Ebay. I live in The Netherlands and my provider, Simyo, uses the KPN network with 800mhz (band 20) and 1800mhz (band 3) for 4G/LTE. After inserting my sim everything worked right away. Calls, data, no problems at all. My provider does not support 5G yet
Edit: be aware that you will not receive updates like android 11 (if on 10) or security updates on the V600AM.
I bought the V600AM, I'm in the UK and I can confirm that it works with O2. The only issue is that phone will switch to 2G when making voice calls,soon after hang up it will switch back to 4G LTE.

OK that's useful to know, I'm still not sure about 3g support as where I live in the depths of rural Cornwall we seem to struggle a bit with 4g - it's OK when I'm outside but indoors tends to drop back to 3g, I can use wifi at least. Thanks for the info though

Yeah, the 3g coverage is a thing for me as I tend to only get 4g when outside, it reverts to 3g indoors and I think that may be an issue for me with this phone as it needs to be a daily driver - as far as I can see the USA variants don't support the right bands for UK use....

You could force the phone to be on "LTE Only" with an app from Gstore,but then you won't be able to receive and make voice calls. Not ideal, but considering this phone is from a US network,it will never be 100% compatible with UK Networks. If only someone would find a solution to root it!!!
Which bands use for UK?
Calls will be via 3g if your region coverage that bands.
