Hello all,
I have a S5830M which was bought in the USA. I can't use its 3G in France but the Edge is working.
The things I tried :
- Changing its kernel/ROM/baseband (it presently runs Simplicity V1 with the S5830iXXLH2 baseband). It has been of no use so far.
- Changing its antenna. I replaced the original one with the antenna of a S5830 bought in France (3G worked with it when it was operational). It improved the situation slightly : I had the choice between WCDMA (=3G) and Edge in the phone settings. But when I chose WCDMA, it made me unable to even make a phone call.
Is there anything I can do to activate the 3G on this phone ?
Thank you in advance for any help you can provide :good:

I am using this phone in VN too and I got the same "seem-to-be problem". Per information from T-Mobile Support forum, this may be because of a customization that T-Mobile made to the phone where there is no longer 3G symbol but either EDGE or 4G.

T679
This problem could be related to the band on the phone works usually a TMobile phone works on band 1700 gsm check your at your country provider if use the same.
You probably receiving edge signal which is very slow.
could anyone tell me why the 2100 not work in hong kong?
I think SGH-T679M does NOT support HSDPA 2100 which is used in Asia & Europe for 3G?
Experts please confirm
I bought a Chinese Clone of an HTC S720e and I cannot get it to "see" the ATT wireless network with my SIM card. Says Network Not Available. No voice calls, no signal, no data, no nothing.
Info is HDC G23i ONE X S720E 4.7'' Capacitive Screen 3G WCDMA MTK6575 1.8Ghz Dual Core Android 4.0.3 Dual sim 8MP WIFI GPS
Specs can be seen at http://www.fastcardtech.com/goods-7353-HDC+G23i+ONE+X+S720E+47+Capacitive+Screen+3G+WCDMA+MTK6575+18Ghz+Dual+Core+Android+403+Dual+sim+8MP+WIFI+GPS.html
It's supposed to be able to work on 900 and 1850 MHz like ATT needs.
I called ATT and got them to accept the IMEI that came with the phone. (It's actually one of those Dual SIM card phones).
I have tried a million different APN settings and nothing seems to work. The phone doesn't see any signal at all! Really makin me mad.
I tried a Star N8000 from China before and it had no problem working with my SIM card. Why can't this one?
Appreciate any suggestions.
Bump! Also I notice when I turn the phone off, it says "Restricted Access Changed"
Any soultion to this? I have the same problem connecting to Swedish network, Telia

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

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
Hey guys,
I've just got this Galaxy S3 which was bought from m:ts Serbia and put in my Telenor Serbia SIM card - everything worked fine, i could make calls and everything but I realized that it could only establish an EDGE connection and no HSPA or any other 3G connection. When I select WCDMA preffered, it still only gives me EDGE or no signal at all. I've tried installing Cyanogenmod but no luck, the problem persists.
