Help with Tilt/AT&T in S. Korea

Hi, first post, searched a little...need help
I bought a tilt in December from AT&T, an 8900 non camera. I'm in S. Korea and I cannot get service. I have international roam activated and AT&T has confirmed account settings are correct...Here's the deal:
1. Phone searches for a few minutes and the I get an exclamation point.
2. Goto phone settings and see "no service"
3. Change network settings from auto to manual.
4. Phone finds KTF and SK Telecom (the two providers here in S. Korea).
5. Tries to register and generally there is no feedback, but on occasion I have received the message "Cannot read settings from the network. Try viewing settings later or disconnect data connection and try again."
6. Data is not connecting.
7. AT&T technical support (level two after the customer service rep) says the problem with the tilt is I cannot force it to use umts 2100. Then he came up with the idea that my SIM is from AT&T and that's the problem, I have to go get a local SIM from SK Telecom, but I was here in October with a Palm750 and an ATT Sim. Worked like a charm.
I'm stuck....could use any help at all!!!!
Thanks,
Steve

Are the carriers that you are referring to CDMA or GSM?

The local carriers are WCDMA/UMTS 2100 and I've downloaded the band tab dll from another post and confirmed that I am on the correct band...
I'm almost convinced it is an account problem. As of this morning my phone would continously come up with a "select" network screen (As there are 2 networks here). I select either and get the message "unable to register on the selected network, choose another or change data connection type"..
As I understand it, when I roam, my sim or phone # attempts to register across the local network to my home network and it needs authentication before I can have access...
what do you think?

bump....anyone with experience at all here?

In a simialar boat soon
I will be moving to Korea soon (Military) and I have an 8925 (unlocked) and I am wondering if I will be able to use my phone with either SK Telecom or KTF (both have GSM, I checked.)
If so, will I have to change anything in my phone? I'm using Dutty's WM6.1 Hybrid v2 5.2.19716 with the 1.65.14.06 Radio.

Using a UK HTC Touch Diamond in the US

Hi all,
I'm new to MDAs and to these forums so bear with me. I looked around quite a bit and have been unable to resolve my issue. I obtained an HTC Touch Diamond (a T-mobile Compact IV) in the UK and am trying to get it working in the US. While in the UK there were no connection issues but as soon as I got to the US the connection is unstable. I have managed to make about 10 calls in the US but they cut out after a short time and most of the time I cannot make a call or cannot connect to a network at all. It can always see Tmobile and AT&T but can rarely connect, and when connected can rarely call. I have flashed the TLR 3.08.07.16 WWE ROM and updated the radio ROM to 1.09.25.23
Any help would be greatly appreciated

from my basic knowledge of radio, uk networks use gsm while most us networks use cdma that mite be your problem!!
try going to start>settings>phone (in the personal tab)> scroll to the band tab and change ur network from auto to wcdma!! you may also have to change the band setting your using, but u may have to check with your network on what frequency they use

Thanks for the suggestion. Thus far I have only been able to connect on GSM, CDMA has never worked. I also have been using the 850 1900 band which I heard is the one used in the US. I have connected occasionally but am still having trouble.

No Service

I am not sure if this the right place for this discussion but I've got a problem and need help. My ATT Tilt works fine in my home service area (3G Network) with 4 bars consistently and drops the connection as soon as I leave it. I've Tweak the setting, stripped the software off except for the basics, hard set the phone, and nothing works. ATT replaced the phone twice but didn't solve the problem. I leave my area and No Service. I travel a lot so this is a major problem. Is there a solution?
WM6.1
ROM Version 3.57.502.2 WWE
Radio 1.65.21.18

hmm not sure if it helps..
I read somewhere that if U turn of 3G and use normal GSM, it might help...
maybe other areas do not have 3G network and only normal GSM networks?

Thanks...I installed "Enable Band Page (Tilt Rom).CAB" and changed the GSM/UMT Band settings. Now the phone works out of area.

and how did you come across that cab file?

Desperatly need help getting 3G instead of E

Hi guys,
I brought my first xperia from my phone serivce provider, and it always had the "3g" symbol at the top. However, when my xperia broke, I had to buy another one and got one of ebay. Since I brought the new one, my phone always has the 3 on top. I'm currently using the firestorm valkyrie rom which as the htc interface. When I go to the data connections it says an option (3g) "change to gsm mode" and on is selected. Even when I toggle that, it still always has the E symbol. What do I need to do? I know my sim card is cabable of getting the 3g. But this is a real pain because every now and then my phone just doesnt receive service, so I constantly go onto the comm manager and then it seems to just click that there's service and shows 2-3 bars. Then all of a sudden again after a while there'll be no service. So I'm guessing that's because of the E thing. It shouldn't be my current location as I've never experienced this before.
Is there a setting I can go to to get the 3g symbol? Or a patch I might need for the phone?
Please help
Kindest regards.

You need to change while the connection is not active, I believe. Or... you got the Xperia version incompatible with your network... Or... the ROM is buggy, try another.

sorry, I need to change specificially what when the connection is not active? Say you mean, turn off my phone settings and not connect to the network and then adjust something? It is not the rom. and the seller on ebay has stated that it is a 3g phone - many others have brought it as well with no complaints.

3G settings on x1
Hi
For some reason your phone is only camping on the GSM network (G or E indication depending if your carrier provide GPRS or EDGE on the GSM) instead of the 3G network (which you have been using before).
In settings, communications you should be able to set "3G change to automode" to on,
When this is set your network provider will tell your phone to use the 3G as preffered network, but when coverage is not good enough it will drop you back to 2G (which has a better reach due to lower frequency band).
If it does not happen automatically there might be another setting that is wrong,
goto settings, all settings, personal (tab), Phone.. then choose the "band" tab (need to go to the left with the arrows) , then you have the dropdwn lists to set:
select you network type (need to set auto or wcdma to get 3G)
select your GSM/UMTS band (need to set 900+1800 for europe, 1900+850 for us, dont know who is using 2100+800)
once changed the phone will restart the phone part and search for your carrier in the right band.
good luck

Hi,
Thanks for your reply. I had changed the automode to on. But still had the E.
I went to the setings, and band tab, and i had selected:
Select your network type:
(blank)
Select your GSM/UMTS band:
Auto.
I changed the first oen to auto, and as for the last, here in Australia I'm with Tesltra which is 850 UMTS? I think I read online. Anyway it didn't have the option in there, so I went through them all but wouldnt get service at all except for the first: GSM (900+1800)+UMTS(2100+900). and Auto. I think my last experia might have had auto for all of those too. Anyway with those only two options working, I still get the E icon. Even tried setting aeroplane mode on and then off to see if it might register, but it didn't.

I see , Telstra is one of very few networks that use 850 for WCDMA so they might be using a different RADIO ROM than the rest of us
I saw in the thread below that there is a TELSTRA AUSTRALIA (1.03.841.8) R2AA008 version..
http://forum.xda-developers.com/showthread.php?t=477801&highlight=telstra
you probably need to flash that one to get the 3G working on telstra..
3 is using the normal 2100 so you could also try with their SIM just to check that there is nothing wrong with your hardware..

Sorry for the late reply.
I have realised that i'm in an area that doesn't support 3g. however my last xperia phone which I brought from telstra was the x1a, which had the next g network - hence I got the 3g symbol. However I have found that that I have the x1i, which doesn't list that network. I rang up telstra, and they transferred me to the sony erricson call centre, and they said you can try and do an update but it is not gaurenteed to get the next g service. I have already flashed a htc rom and don't particluarly want to change it back, unless i'm certain that I will get the next g service.
With the rom you have provided, do you think it will have the UMTS 850 band on there, and my x1i would be able to connect to it? I would have thought that it would be a hardware preference, not a software. In which case, even if I updated the rom because there is say no "chip" that allows for connecting to that band, it wont connec to it even though I may have selected the 850 UMTS band.
Sorry if that seems all over the place, but yeah... I'm not sure.

Why im Roaming with AT&T phone + BELL / TELUS SIM

Hi,
I would like to be able to modify my AT&T radio and change the default Mobile Network Code for my carier, is there any software to make easy to modify the ROM file ?
Thank

I'm not quite sure I understand what you're asking, but a radio will work on various different networks, depending on which SIM card you have in the phone. So I'm not sure that it's in the radio that you need to look.
What is it that you're trying to achive exactly, why do you want to change this code ?

Well, here is my problem;
I bought a Tilt 2 on ebay, and I also get an Unlock code for it. I have inserted my Bell SIM and the phone work correctly. I have configured the APN setting correctly and now I have internet without any problem.
The only bad thing is that the phone always think i'm in roaming, but that's not true. I have to deactivate all setting about roaming check, it's not a big thing but If I got to USA I will be charged for real roaming. and another downside is that many application pup info about roaming and data charge.
I'm searching since couple days to found a solution, and I'm pretty there is one but I have not enough knowledge on programming stuff. I've look all every registry in my phone and no one can't correct this ''roaming'' situation.
That's why im turning to Radio, since this phone is an AT&T, it's propbably seaching to compare SIM network provided and ROM network. I've found an interesting site about MMC/MNC http://en.wikipedia.org/wiki/Mobile_Network_Code
and found that the default network for AT&T is 310-410. Here in Canada We have bell and telus that use same technology then AT&T (UMTS 850 / UMTS 1900).
I would like to change the default ''home'' network code to 302-880. because my Sim Provided IMSI is 302-610 (Bell).
So to make it short. I want to change the default ''HOME'' network 310-410 to 302-880 so the phone will not be in a roaming profile.
Hope that someone can help me, and I'm pretty sure many people will appreciate this fix.
Thank You.

I don't know much about this, but surely it's your SIM card that is providing this code ? Since I could buy an unlocked Tilt 2 and put my own SIM card in it, and use it fine here in the UK on a UK network.
I can't believe that your phone thinks it's roaming just because it's a Tilt 2.

Yes, I found in my registry ProvidedIMSI="302610" that is the SIM registred network 302610 Bell HSPA network. So my SIM is telling the phone to use this network, but there is something in the phone that say it's roaming and not a home network. and I need to find and change this.
I'm not the only one in this situation and i would like to find a fix.

i have no knowledge about this only thing i can think of at the moment is just change the current radio version and flash a new rom. the latest version for radio is
4.49.25.95
and is found here ------> http://forum.xda-developers.com/showthread.php?t=549939
follow the right steps. [:d]
best of luck

Yes, I've updated the Radio to the latest version and still have the problem of ROAMING. i've try 2 old radio and always got the roaming icon.
Any other input will be accepted!!
Thanks

I read somewhere that roaming starts when you are out of your area code range.
But you can try this too
go to ------> setting ---> personal ------> phone -------> Network (in the bottom tabs)
In the network tab click Find Network and make sure it is the same network you are using.
Network selection should be "Automatic".
Now in next tab BAND
select network type to "GSM" and GSM/UMTS band to "Auto".
Try this and let me know if this work else i will ask somebody knowledgeable like Sir Phunkee

I've play with these setting and nothing seem to work.
But maybe I found something interesting.
I've just test the phone with a ROGERS SIM card and I get 3G signal and i'm NOT in roaming mode..
Now, What that mean ? Rogers 3G is UMTS/HSPA 850/1900MHz same as BELL.
Why it say Roaming when phone is connected to BELL with BELL Sim and not on ROGERS SIM??
Could someone help me with that ? fix, cab, anything ?
Thanks

rooming
Hi
I do not know think you want to do with your tilt 2
Why you don't do a hard SPL and install a cocked rom !! as energy
I am using a tilt purchased from AT&T without contract
I get a unlock cod from the internet then I do a hard SPL it and install the energy rom in, is work like a charm with Rogers, without any problem( only the gps wish I never try
Perhaps this is can resolve your problem you should try
thanks

Already done Cjoco My Tilt 2 is Unlocked and Hard-SPL with latest EnergyROM.
Like I said before, SIM ROGERS work like a charm in my phone, No roaming warning. but with BELL and TELUS SIM I get the Roaming notif but it's not true, Im connected to BELL and VOICE,DATA,etc. work #1.
People say that it work with ROGERS because this carrier have a fallback signal if 3G is not available, with BELL if I lose 3G signal my phone doesn't work.

then i think problem is with your sim card not with your phone. Just get your sim card replaced and i am sure the problem would be resolved.

the problem may be with his sim card, but im not sure replacing it will fix anythibng. im also with bell and have the same problem on my fuze.
bios2k, how old is your sim card?

bobzero My SIM card is 2 Week Old. so, i'm not sure it because my SIM is old.
I'll give a call at tech support @ BELL to see if they know why it doing this. I'm not sure if they will be enough good to explain this situation.
I've read last night on many forums the RILPHONE.DLL could be a possible cause of our problem.
In my config I can select GSM(850,1700) + UMTS(850,1700) but there is no option to select UMTS only. so maybe the phone is searching for GSM first (rogers) that's why when I insert a ROGERS SIM my phone is not roaming.
Is there a way I can extract RILPHONE.DLL for our EnergyROM or Stock Tilt 2 rom. Maybe I can ask a Programmer to take a look at this DLL to see the code.
I'll let you know.

I've just talk with BELL technical support and they have no idea why I'm the phone say it's in ROAMING. I've talk to the billing department and they say I don't have any ROAMING fees, so nothing to worry about..
Now, I'm still at the same state = no solution

Same here.
I was checking around and found many got this problem, including BBs. Now, some claimed that after upgrading the O/S for his BB, it went away. Another person with different device upgraded his O/S and started having that problem, and it wasn't there with stock ROM.
Make me think it has to do with the software side of thing and nothing to do with SIM or radios. To pinpoint what is causing it, can be a tough task though.

scooper True, Hard task for people that don't know much about programming ROM and files, but maybe we can have help from other that wanna look at our problem.
I'm available to test if someone want to Help us .

You should try to change the radio and rom of your phone. Make sure to Task 29 b4 flashing. Another thing to make sure is you use the right radio, i mean the specific radio for telus, t-mobile or att.....
Wrong radio can also cause such problems.

I have the same issue with my Unlocked Tilt2 on Telus. I found a lot of people with unlocked winmo devices on bell/telus complaining of this problem and never have seen a solution. People say that a Fido sim will do the same thing. Only Rogers sims seem to not show roaming. PLEASE post if you find the solution or even cause of this.

I just did task29 and reflash ROM. I soon as I have the main menu Roaming Icon appear on top just beside or 3G.
Damn!! still stock with this roaming issue
anyone have Q's ?
