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

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 ?

[Q] [SOLVED] Can't Get Data (3g) need help

PROBLEM SOLVED - DEFECTIVE SIM CARD. Thanks everybody !!!
Hi guys,
I really need your help with this one, here's the deal :
1. just bought my second SGS from vodaphone CH last week.
2. the phone came with 2.1 stock
3. i was not able to get data connection (able to make phonecalls and sms, but no 3g)
4. my apn settings are correct (i have another sgs configured same way on same network)
5. decided to upgrade to 2.2 (JPH) hoped this would help - NO
6. updated MODEM & CSC to the SAME ones working on my second SGS - STILL NOT WORKING
what else could it be ???
THANK YOU FOR YOUR HELP

did you install DroidWall ?

Nope,
Never heard of that Apo.
Can it help ?

Here's what's there, can you see what is wrong ?

Try this, worked for me
This is a weird coincidence. I have (had!) the exact same problem.
My problem was when I reflashed my galaxy S with stock firmware back again, I lost 3g connection. Using a different sim (which supports only Edge) I was able to get edge connection but with my sim, there was no connection.
Here's what I did. It seems when you select the band selection to "Automatic" it somehow didnt get registered properly even though it showed up on the settings->Wireless and network->Mobile networks->NetworkMode. Even though it read GSM/WCDMA (auto mode) it wasnt actually the case.
So - type *#2263# on your phone to enter the Service Mode's Band Selection.
There see if first row is [1] AUTOMATIC[] OR [1] AUTOMATIC[*]
In my case it wasnt selected ie. there was no *. So I clicked on it and did that selection myself and baam!! H connection. It connected even before I exited from service mode.
I tried a 2g and 3g card after that multiple times and it connects properly to E or H from then on.
Give it a try. I am hoping that your APN is set properly.
Anup

Thanks for the help, but unfortunately this didn't work :-(
1. Automatic was selected.
2. Ive tried to play around with the options there and within the mobile networks.
Nothing works ... this is so frustrating :-(

Why didn't you just call Vodafone and get their help before flashing the phone If you already have another SGS configured same way at the same location with 3G, then chances are there is a hardware problem with the phone.
Anyways, try contacting vodafone, they might still do something about it (despite the fact you have voided their warranty by flashing).

[Q] "Your sim does not allow connection to this network" error

Bought a Galaxy S yesterday. It is originally purchased in the Netherlands, but i'm using it in Belgium now. When buying it, the device got tested with proximus and mobistar sim card (main providers in Belgium) and seemed to work (sms and calling worked). Getting home, putting in my mobile vikings sim card, I didn't seem to get any service. In my notifications bar it says BASE (which is the network mobile vikings uses if i'm not mistaking), but i'm not getting anything.
When searching the providers, mobile vikings is shown, but when selecting it I get :
Your sim does not allow connection to this network"​, which is strange since it's a mobile vikings sim card.
Never had any troubles, and sim card was working moments before testing on the galaxy S
No custom rom installed or what so ever.
Any help would be greatly appreciated since I can't do anything with the phone atm.
Thanks in advance!

I had this problem about 8 months ago... If i remember correctly I just had the wrong modem flashed... I was missing a modem with 850 band... try flashing Ugkc1 of jk4 modems... also check to see if your APN(access point names) are in your wireless settings

Just got a mail back from my provider, they're sending me a new simcard. But I doubt it's going to make a difference...
My apn settings are all ok. Don't know about my modem though...Don't know what it is, or whta it's supposed to be

I am pretty sure you probably need the 850 mhz modem in your area then..
what is your current baseband (settings>about phone)
New Sim card won't fix your problem.

My baseband is XXJG1, and I'm still on Android 2.1

My suggestion to you would be to download JS8 which is 2.2 and flash it with ODIN
http://www.samfirmware.com/WEBPROTECT-i9000.htm from here (you need to sign up)
see if that fixes your problem...
if it doesn't work, stay on JS8 and flash a modem(phone) file only that has 850 enabled... like JK4 or KC1 (there are more then those 2)
Just look up steps on how to flash with ODIN and check you tube for videos... just be careful...

Thanks a lot for the advice. I'll try it this weekend. (on a mac atm,and can't get heimdall to run)

UPDATE:
I tried flashing my modem without any result as far as I could see. Tried flashing darky, without result.
Got my new simcard from my provider, but nothing . I'm back on stock now FW 2.1 update 1 and baseband XXJM3.
Strange thing is that I get edge and 3G, to which I can connect. So my mobile internet from my provider is working, but no signal what so ever...
I'm starting to get desperate here...

I was also similar problem on my i9000t and i897 used in India. In my case the problem was intermittent. The solution i arrived at is as follows:
First select a modem that works correctly for your Band. Now force that particular band from SGS tools or going to service mode by dialing *#2263#. For example I force GSM900 for edge and wcdma2100 band for 3G. After that let your mobile choose select the network. Be patient for 10-15 minutes, it should work.

[Q] Milestone Moto basebands help pls

Hi all, great forum, I've learned quite a bit from just reading all the threads but I have a headscratcher I couldn't find anything on and hopefully someone can answer this as I'm losing my mind trying to figure it out.
I have a Telus Milestone which works perfectly fine with CM7 RC12 on the Telus network in Canada. Every time I travel to Europe or other places it just won't connect to the local network, just emergency calls.
I tried every single baseband in AOR 3.3 but nothing works. I also tried different roms (Cronos X 1.5, FroyoMOD 2.9.1, wiping phone, factory reset, etc.
Even tried the Moto Defy baseband switcher with no luck. AFAIK this phone is capable of 850/1900/2100 bands.
Really appreciate any help!!!

Well, according to this - http://www.howardforums.com/showthread.php/1641030-Does-the-Telus-Milestone-support-2100MHz-3G - Telus Milestone should support European frequencies, but not 2g and it have same hw like MM for Europe.
Some time ago I was a TelusLite rom for Milestone user and it was working well with 2g and 3g after change to Germany baseband (in Poland). Without baseband change it was only working on 3g.
Maybe you need to flash some European-compatible rom (eg. FroyoMod/CM7) and then try?

Thanks for the quick reply.
I tried changing to Germany baseband which should work but it doesn't. In my case I'm trying to connect to Orange Romania which uses 900/1900/2100.
I did try FroyoMod which is Italian if I'm not mistaken, it was developed by 89luca89. Also tried different flavours of CM and Cronos.
It almost seems as if I have to unlock first or maybe Telus is blocking my account from roaming... is that even possible?
I've ordered an unlock code from cellunlocker.net, hopefully after unlocking I can use a local SIM and see if it connects.
Thanks for the help!

Hm. It is strange that it doesn't working on every rom.
Maybe Telus don't have an agreement for roaming with Orange Romania? I think that it is a problem with one of the cell operators, not with your phone.
Good luck with local SIM

Yeah, strange indeed.
I doubt it is Orange RO as I tried it in Paris, France last week and it wouldn't connect to any network there either, Orange, SFR, etc. A couple of months ago I couldn't connect to Cubacel either. I just figured the commies don't like Canadian smartphones. LOL
I have a feeling Telus has my account locked from roaming. I'm praying the local SIM will work.
Thanks again!

Well, just as I suspected, Telus must have the SIM locked from roaming. The unlock code from cellunlocker.net worked like a charm. Phone connects to local Orange RO network, full 3G data connectivity too.

It's good news I'm happy that you managed it to work.
Looks like Telus don't want you to use other operators. But there is no impossible things

I had try to use the t mobile sim card on my old phone and everything will works fine with no signal lost.
Can anyone please HELP!... I been searching and looking for an answer for more than 2 weeks..but no resolve.....

This is probably because T-mob covers only particular places the frequencies this phone uses http://theunlockr.com/2013/07/05/htc-one-sprint-specs/ vs t-mob https://t-mobile.jive-mobile.com/#jive-document?content=/api/core/v2/documents/4988

Is there any solution for this problem ?
Is there anything I can do to fix this problem ? (different rom or radio...etc..) Or I have to give up the phone... Cause it is too much headache to "searching for network" all the time and miss all the call with no service on the phone without knowing..
Thanks

well, I am not an expert on the tmobiles network, but going by what lazybozz, said, I seem to remember tmobile using different bands than the other carriers, so what you may be experiencing, is the phone being in the vicinity of multiple towers, but not all of them are within the band that the phone supports. So its like the phone doesnt even see those towers. On a side note, this issue caused alot of chaos for those who unlocked iphones about 3 years ago, they could use EDGE on tmobiles network but not 3G, so i assume this is a similar situation. So long story short, yeah you probably cant fix the problem, unless you get a quad band phone. I could be wrong, but it does sound like a logical reason for the issue you are having.

as elvisypi said above, Its the freq that T-mobile operates on in that area. If your getting T-mobile at all in the states then you have already flashed a radio. However flashing any other radio is not going to give you the freq that tmobile uses, Its not a software limitation its a physical hardware limitation.

Thanks for your reply, do you know any app out there that monitor and alarm you when the network or signal is lost ? That works with 4.3 ?That way at least you know the phone is offline ... some of the apps I tried is anything at all ...
Thanks

Have you tried an app like tasker? Its essentially an automation app. It isnt jist for your use. Its for many different functions. Jist look on the app store for tasker. That might help
