Thanks in advance.
I also tried my SIM card on other smartphones and it worked, i could surf the internet wihtout a single problem.

Silly questions but:
Could it be you are in airplane mode?
Do you insert your sim correctly?
Is packet data checked in settings>wireless and networks>mobile networks?

maybe you can try flashing different modem for your tab see here http://forum.xda-developers.com/showthread.php?t=1867147

I flashed stock ICS ROM 4.0.4 Italy using ODIN on P7500 earlier running stock HC 3.2 INU. Then I have installed the voice dialing mod. Now both voice and 3G have been working well.
Hit Thanks Button If It helps you.

[Q] AC100 built in 3G modem disappeared

Hello there!
Can anybody help me? I also have an AC100-10v and it's 3G modem worked fine with Android 2.1. Now that I've upgraded to 2.2 it doesn't see the built in 3g modem. There are no marks of it in the system. No menu entries for the mobile phone feature. Wonder how I could get it up and running because I've bought this device to surf with my SIM card.
Thanks in forward!

Hey, all good. Just type by hand your mobile provider APN settings(Settings-Wireless...-Mobile Net..-Access Po..-Then push the menu button-New APN-Then type in Name what ever you want and in APN exactly what it must be). If you dont know the APN, just call your provider and ask the APN.
CHEERS!

[Q] [n00b] SHV-E120S (KOR Glxy SII HD LTE) Need help to help!

Hey guys,
Longtime lurker, first time poster and all of that.
I am in possession of a brand new Samsung Galaxy S2 HD LTE (Korean model SHV-E120S).
I would love to help get custom ROMs and other things onto this device, and I'd be happy to dump my phone or provide system images... if I knew how to get them!
It seems Samsung does their mounts a little custom, as the ROM dumpers I've found don't work (missing a /proc/mtd). Can anyone point me towards how to get a dump of the .img or other files someone much smarter than I needs to get development off the ground? Even if devs don't pick it up, I'd like to get a dump of the files anyway for my own tinkering.
Appreciate any replies
hi brother l have the same device and l want the full firmware .I found the room but not the full firmware I need the PDA and pit files .go to the first section (galaxy s2 general) then go to (Korean galaxy s2 ....) on page 54 and 58 you find 3 links for the room
Yes, I saw that ROM posted before, though the tar appears broken.
What I am looking for is a tool or a guide for dumping the ROM myself. I have rooted the device (Zergrush v3) but not much else.

Hi.
I have the shv-120s and I also want a full firmware.
Love the phone. But I want swedish meny.
I think there's only English, Korean and a [custom?] Chinese ROM for the Galaxy S2 HD LTE (SHV-E120S) and LTE (SHV-E110L) phones.
If you want to update your firmware, try Samsung Kies software:
Code:
samsung.com/ca/support/mobilesoftwaremanual/mobilesoftwaremanual.do?page=MOBILE.SOFTWARE.MANUAL
So have any of you been able to use this phone in America? Are you using a custom or stock ROM? Korean or Chinese? When I try to use the phone here in Canada w/ Rogers or Fido, it won't connect to any HSPA/3G networks. Can anybody can help?

I am actually in Korea for the next year and change, so I can't vouch for it on Canadian networks. From what I know of the radio, it should work on Rogers GSM networks for 3G, but it won't get LTE/4G service there (different frequencies in Korea/North America). Are you sure your phone is unlocked?
I am running the stock Korean ROM 2.3.6, but I have rooted mine with zergRush.
Actually I should get 3G & LTE (because Rogers claims to use LTE 2600) but no HSPA+. It wont connect to the network. I suspect that it's possible that the ROM is keeping me from connecting since it's asking me if I want to use Network data outside of South Korea. I suspect the ROM wont connect to foreign data bands. I was just wondering if there was any way to try another ROM...
Hi all,
Last month I had just bought Galaxy S2 HD LTE (SHV-E120S) in Korea and bring it back to use in Malaysia.
Everything is working fine except for SMS.
I am able to send and receive SMS by using the default SMS program. But i can't send out SMS if i use third-party SMS program i.e. GoSms, Handcent SMS.
My phone is not rooted. Details as below:
Firmware version: 2.3.6
Baseband version: SHV-E120S.EL21.0917.ST
Kernel version: 2.6.355.11-E120S.EL27.1737-CL776986
Build number: GINERBREAD.EL27
Somemore, when i tried to restore the SMS backup from my old phone (I9100) to this SHV-E120S, using GoSms, "SMS to Text", "Backup to Gmail" etc, all the old SMS didn't go into default SMS program, instead, it showed only in GoSms or Handcent SMS.
I'd already done the factory reset but the problem still exists.
Do you guys have any idea on this issue?
Appreciate any help from you. Thanks.
Hi guys I am having the same problem, SHV E120s, test messages with GO SMS pro worked initially, but now i am unable to send regular sized SMS.
Just wondering if anyone has figured out how to fix this, or what the issue is
Thanks!

[Q] Svoice works on Rogers wifi and not on Telus data.

Using OnlyOne Beta 2 - UCLE2 *SGS III TW* *SVoice* - Stock, Rooted, Deodexed. Fantastic ICS Rom. Thanks to Devs for this! (kifac & flappjaxxx)
Wiped everything, rebooted flashed with beta2 update.
On Telus network Svoice gives "Network error.Please try again."
Connected to Rogers Wi-Fi, it works like a charm.
Tried build.prop edit as per some threads - no go!
Settings for network seem correct. LTE and 4G run well.
APN settings are default Telus.
Anyone manage to get Svoice to work on Telus network? If so, what rom or modem are you using.
Thanks in advance.
(first post, hope I did it right!)
I am also having the same problem but with the beta 4 ROM.
If anyone can help please do!
