E210L - 3G or GPRS only?

Hi guys,
I can't find any answer to my question about data connection of SIII Korean model E210L. I can connect only to 3G or GPRS (tested at two diffrent countries at two GSM providers). There is no E (Edge) or H (HSDPA). When I lose 3G reception it drops always to G. Have I missed something in settings? Any help or explanation? If this question is answered alredy, please help me to navigate there.
Thx.
If you have flashed a custom rom you may need to flash a different modem. I put a different rom on my phone and lost 4g in australia. I had to re flash an australian modem. Telstra modem to be correct and then I got 4g back.
Give that a try.

No one can explain? Does someone is able to get Edge or HSDPA on E210L model?

This is the wrong forum for that phone... I'm assuming you're using the phone in Prague, on which carrier?

Yes, maybe, but I hope some user with E210L can help. E210L is Korean version of I9305 model. I tried this phone in Prague with Vodafone and now I work in Asia in Vietnam so I use Viettel. At both operators I can get only G or 3G. Why?
Probably because LTE in S. Korea uses pretty uncommon frequencies not available in other parts of the world, as to why you can't access HSDPA or Edge I have no idea.

Yes, LTE in Korea is specific but I don't care about it because here or in Prague LTE is not available. I only don't understand why HSDPA or Edge isn't reachable. I guess even Korean people travel abroad and want to connect to Internet for example here. Anyway thanks for your replies.
There's no edge and hspa icon in korean s3.
Only gsm (g), 3g and lte icon.
I think G also represent edge same goes with 3g.
In 3g icon i got hspa speed which is around 3mbps.
You have to set the network to automatic, as korean s3 is lte prefered as default.
this menu is hidden, you set it by following :
-open dial pad and enter : 319712358 then a menu will pop up asking for password.
- password for LG U+ - 0821
- open network
- set automatic
I think what diontoradan said could be your problem, could you do a speed test when connected to '3G' and report the speeds you get.
You should beable to tell what type of 3G connection you're actually using going by the speeds (appox)
Its obviously not a accurate way to find out what type of connection you're using but you wont be getting speeds of like 3-5Mbits with just the standard 3G connection. You are probably on 3G+/H
You could also do the test when connected to GPRS (G) if you get above 20kbps then you're using EDGE.

diontoradan is right.
I can get 6.57Mbit/s with that 3g icon .
hey guys, i also have a korean s3, intially it didnt show any 3g networks...did some research and got to know about the hidden menu, changed the network to wcdma only...now after using it for months once again i'm getting the same issue......no 3g networks gets registered only 2g....is there any solution other than returning the phone???
Thanks alot in advance!!:angel::angel:

[Q] Is it compatible with T-Mobile new LTE network?

I really want to know if this xperia z will be compatible with the new T-Mobile LTE network and its HSPDA+ network?

LTE has more chance than HSPDA+, most US 3G networks are not supported from the 6603, only the 6602

Regarding 4G/LTE in C6603

Hi guys I have a question. I'm seeing other Sony Xperia Z devices with LTE as shown in the Network Mode but mine is only 4G. By the way my device is C6603 and it shows [WCDMA only, GSM only, WCDMA (preferred)/GSM and 4G (preferred)/WCDMA/GSM] but I saw other device LTE (preferred)/WCDMA/GSM instead of 4G (preferred)/WCDMA/GSM. I'm worried that I have a non-LTE device. Is there anything wrong in my device? Thank you in advance!

LTE and 4G are basically the same as far as your handset is concerned.
Some phone carriers call it 4G, some call it LTE. There;s nothing wrong with your handset!

Unfortunately you cant enable LTE for band 4 by flashing baseband files its more related to hardware than software.
For T-Mobile/Verizon you will be stuck with EDGE and on AT&T you will get 3G
arent any providers with other bands out there in US?

Other carriers are dependent on the major carriers for network allocation
