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 ?

[Q] 850mhz band broken on my phone? (''Unable to connect. Try later'' got me crazy):

Hello guys! I've been reading these forums for a long time, amazing what you guys do in here
Here is my problem: I live in México, and I traveled to USA for summer vacation, my mexican mobile phone carrier uses 850mhz (TELCEL) and when I went to USA it was using ATT's network.
So everything was working fine, but when I returned just before I was about to cross the border, it stoped working!
It has a message that says ''Emergency calls only'' where it's supposed to say ''TELCEL GSM'', so no internet, no calls, no messages.
I was using Froyo on my phone, and thought of doing a reset to restore factory settings on the phone, but it did not work :/
Then I updated my phone to Darky's Rom 10.2 (Gingerbread) and it's still not working!
When I go to Settings>Wireless and network>Mobile networks>Network operators I can see that my carrier is available to select, but when I try to, it gives me a ''Unable to connect. Try later'' msg.
It is really frustrating because I depend on my phone so much, mainly because I share my 3G connection to my laptop for school's work and stuff.
There's one weird thing though, I unlocked my phone, and placed a MOVISTAR(1900mhz) SIM card on it, AND IT WORKS!!!
But the thing is that I don't have internet on that SIM card(is prepaid and it's EDGE, not 3G), and on my TELCEL SIM card I have a contract to complete (still a year to go).
When I put my SIM card on someone else's phone, it works like a charm, but if I try to put a TELCEL (850mhz) SIM on my galaxy; just says ''Only emergency calls''
What do you guys think happened to my phone? I would really appreciate your help.

flash a new modem... one that contains more frequencies enabled.. any bell or telus will do.
UGKC1 modem should fix your problem.

It did not work, should I keep trying with other modems?

you can.. jk4 or jl2 are other modems with 850 and 1900 enabled... maybe your problem is different then I thought... but it sounds like your modem... maybe try unlocking your phone? if you can connect to wifi download sgs unlocker pro (paid app) in the market to unlock, your phone also needs to be rooted. are you using the i9000T? that may be different problem altogether...
edit: sorry I see you said it is unlocked... just doesn't sound like it...
a) modem related (ugkc1) should have fixed that
b) SIM carrier not compatible to phone (unlock phone to fix)
c) Busted SIM card, check in other phone
d) make sure phone option is set to Automatic CDMA/GSM
sounds like you checked everything I would check....
does your 3G work... make sure your VPN is setup to your carrier

maybe imei got blocked...? only way around that is to get provider/samsung to unblock

Hey have you solved this, I have the same problem

Question for Motorola Milestone users on Vodafone New Zealand....

Hi guys, just a quick question for you Motorola Milestone users that use Vodafone's network in New Zealand.
First off, I know that Vodafone NZ does not support Milestone. Only Telecom XT supports it. However, Vodafone does support and sell Milestone 2, so I don't see why this couldn't be possible.
Anyway, I'm currently using Android v2.1 (Eclair). I flashed the New Zealand v2.1 SBF on it, and it works fine and all except it's obviously for Telecom XT, therefore I can't get my Vodafone SIM card to work properly. If I change the network from 2G to 3G, then it works. I don't get full signal bars (4 bars), but I get 3 bars most of the time which is pretty stable so it's not bad. However, if I switch to 2G (to save battery) then I get no bars at all, completely empty. It doesn't seem to be able to detect any network at all when I switch to 2G. Whereas switching to 3G the phone is able to detect all 3 networks in New Zealand (Vodafone, Telecom, 2Degree).
Now the reason why I'm on Android v2.1 is because when I was on v2.2 (Froyo), it has all sorts of problems with the WIFI. It's probably because of the kernel or something, and it seems A LOT of people have the same problem with me on v2.2 as well. If you do a quick Google search on wifi problems on Milestone then you'll understand why. A lot of people have suggested to flash back to v2.1 to fix this, and so I tried and it did indeed work for me. But since the only available SBF for v2.1 for New Zealand is for Telecom XT, now I have this new problem to deal with. It's not a big deal, I can stay on 3G. But if possible, I'd rather not because it seems v2.1 uses up battery more qiuckly, and the fact that using 3G uses more battery means I have to charge often and that's something I hate doing.
Now here's an important note. When I received my Milestone which came with v2.2 (Froyo) pre-installed, it was using Europe/UK I believe. It doesn't have problems with Vodafone's network on 2G at all, however like I mentioned it does have problems with the wifi. But the point is, the 2G network for Vodafone works fine on it.
So ya I'm just wondering, are there any Milestone users out there that flashed a different SBF, say Europe for example, and able to get the Vodafone network to work fine on 2G, while also making wifi work fine as well?
Or, are there any basebands for New Zealand that I can flash? There doesn't seem to be any from what I found.
Oh and here's where I found the SBF files in case you're wondering, here's the link for v2.1 (Eclair):
http://and-developers.com/sbf:milestone
and here's the link for v2.2 (Froyo):

Droid 3 In Australia

Hey, I'm in Australia (GSM) and I purchased a Motorola Droid 3 (XT862) from America a few months ago.
Should I have bought the XT860 (GSM version)?
I was with Optus but because they don't support the 850mhz network I switched to Vodafone because they had it. So now I atleast have data working on my phone after those months of not having it, but vodafone sucks, especially on this phone (text messages sometimes don't send/signal cuts out all the time) but the 3G is very good.
The phone I previously had before the Droid 3 was a HTC Tmobile G2 which I had also bought from America, and everything worked perfectly.
If I buy the XT860 will it fix everything?
On the Motorola website it says the XT862 and XT860 have the same networks... but the XT680 is supposed to be used on GSM, so would it work fine?
Sorry if I confused anyone, I'm really baked.
Thanks in advance for anyone trying to help

Maybe you could try the T-MOBILE AT&T hack?
Sent from my XT862 using XDA

i have XT 862, on GSM and it works perfectly. More than that, I use also vodafone

The xt860 (and xt883) would not be any better; all they (along with the xt862) support UTMS 850/1900/2100mHz. Thus, you probably didn't get a lot of 3G on the Optus network (which uses 900/2100mHz). The main Vodafone 3G network in Aus is 900/2100mHz, but they are in the process of rolling out an 850mHz network.
Telstra Next-G uses 850mHz (and they have 2100mHz as well, but only in cities I believe)
Anyway, in brief: If you're willing to switch to Telstra, you should get great results. If not, Vodafone is the next best option.

I have xt862 on optus in Austraia. I just stay in global mode. I did experiment around with some of the custom roms but found weirdnesses like my calls not coming thru. I went back to stock and now im going to stay on stock until cm9 reaches release. Im not having any issues on stock.
Hope this helps

Just did it, I suppose it improved the situation a tiny bit, but i'm not sure.
I will do some tests on the Telstra network, see if it's better than Vodafone.
Im using the phone in Global mode atm and I'm getting a decent 3-4 bars instead of the 1 or 2 i'd normally get which excites me
And the network type is displaying HSPA.
But I cannot send text messages, everytime, it just says "Text message not sent" which is very annoying. Anyone know anything about this? When I swapped over to Vodafone from Optus I could send texts but after a point it just stopped working...
Anyone know anything about this?
thanks

So does the droid 3 bought from usa connect to data services with optus at all?
How fast is data transfer in "global" mode?

late reply i know, but I'm on TPG [Optus network] in Qld, Aus with the droid 3 XT862.
from memory, all i've done is done the 'hack' to show actual reception, rather than 1 bar. I run the phone on the global setting.
I just ran a speedtest.net check, got an internode server in Sydney. ping 139ms, DL 5241kbps, UL 1202kbps.
OP, when you were with Optus, did you go through your account settings and make sure you had 3G data turned on for your phone, etc? I'm not trying to patronise or anything, but it always helps to start with the basics when fault finding.
Regards,

Hi All,
Im also in Australia, with Vodafone, and am looking at getting myself a Droid 3 as well.
Since the phones aren't released here, what happens about software updates? Im assuming they won't happen via OTA?
Im leaning towards the XT860, rather than the XT862, any particular reason to go for either?
Thanks,
cevad

No difference between them but the xt860 has more dedicated roms here. Both are the same phone and just build.prop edits are needed to get the phones up and running in 5 mins. OTA updates will still work anywhere tho if you root and mod your phone don't use use the OTA feature as you will screw your phone.
All you need to do select wcdma/gsm mode and manually put in your service provider APNs to get 3G. Find this on the Voda site.
Best place to find your APN is here:

I managed to get a xt862, but I cant get data working on optus? (live connected)
calls/text works - tried global mode, tried GSM/UMTS mode, tried manually selecting optus 3g network, made sure the data setting was enabled which is actually under "battery & data manager". Already manually input the optus apn.
what am I missing?
Do you have to do the tmobile at&t hack? running everything stock from factory; or will rooting the phone/install ics help?
I have the one bar reception bug which I read on another thread if that makes a difference.

nvm, got it to work, for some reason manually inputting an APN didnt work, had to find the optus site and send it via sms.
Speed isnt too bad.
The next problem now though is wireless hotspot. It connects but no data goes through for some reason

If the xt862 is the verizon version, I have read that verizon have blocked the hotspot stuff from working.

no signal, but shows connected to network

Hi there! This is my first post (newbie to rooting/modding, etc), so please be gentle
I have a Motorola Milestone, an unlocked demo from TELUS.
I rooted it, as well as updated the OS with CM7. now it says connected to the carrier, but does not have any signal.
I have tried active SIM cards from TELUS, FIDO, and ROGERS. None are able to get any signal. All the SIMs worked in it fine until I did the above modifications. (I am also in an area that receives good signal strength on the handset previously).
I tried running OpenRecovery 1.46 and switching the basebands, but that did not work.
Any help (in simple, newbie speak) would be much appreciated. I was giving this phone to my young daughter to replace her basic SE flip phone.
Thanks in advance for any helpful replies.
