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 ?
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
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

Hi All,
I am starting a new thread for India specific networks on the Bionic.
I am new to this so please don't mind if i write anything stupid which i may haven't understood yet.
I got my Droid Bionic running on Stock ICS from States to India and inserted a couple of GSM sims which worked fine for a while without any tweaks. I used my device for one whole day(made calls didn't test data) and when in the morning i woke up there was no network. At that time in *#*#info#*#* it was showing as detecting network but as soon as the location updated, GSM would show out of service.
What i have done so far:
1. I flashed Eclipse ICS v 1.2 ROM and got network though very weak but couldn't make no calls.
2. I got ICARUS HD - 1.6.1 and applied the tweaks as mentioned in phone and got network stength increased but still no calls but a strange thing happened when i tweaked with build prop editor running ICARUS HD, when i changed to WCDMA Preferred and turned radio off and on it registered on the network gave full strength and GSM: showed in service as well, though this was only for 10-15 seconds and i couldn't test call.
3. Now I'm running CM 10 - released on Jan 18th and to my amaze I can use 2G Data though GSM state is Emergency Calls Only.
Following might be helpful to understand:
Current Network: TATA DOCOMO
Signal Strength: -99 dBm 5 asu
Neighboring CID: Unknown
Cellinfo: Blank
Roaming: Not Roaming
GSM Service: Emergency Calls Only
GPRS Service: Connected
Network type: EDGE(Also shows EDGE2 at times)
Message Waiting: False
Call redirect: false
Call Status: Idle
Preferred network type:
WCDMA preferred
I have changed to gsm only, gsm auto and all others applicable to no help.
I am trying to run my phone in India on network: Tata Docomo which probably operates on 1800 or it could be 1900 on 3G.
One thing which i am sure of now is that this phone certainly has all GSM capabilities and its some tweak which is required which i cant figure out. I have personally seen my phone making calls and now its running data as well.
Please help me on this!
Seems like settings changed with build prop to run on T-Mobile or AT&T dont seem to work for networks in India. Tmobile operates on 1900 and Tata Docomo on 1800
One thing which wont let me sleep is that why did it run perfectly at first and why did it fail if i did nothing to it. Can the network block the IMEI or something of that sort happened. It's been two sleepless nights for me now, now praying to the Radio God!! LOL!
Did you manage to get it to work? You might be right in thinking that it might be related to IMEI. Did you try and find out if the IMEI is considered valid by your operator since this is not a true worldphone its IMEI might not be in their database?

Didn't work. I had to give up on it. There was actually no way in which i could get it checked with the network.
I sold it off on Craigslist last July!
I now have bought another one to test. Waiting to get back to India to test it again.
Not all bionic works with gsm, only wcdma. It's HW A after 36/11 and HW B

It's quite interesting that it did work perfectly initially and then with CM10, the data worked. Did CM10 rom include its own radio as well?
I found something interesting in this thread (not related to Bionic):
http://forum.xda-developers.com/showthread.php?t=945312
Good luck with your new Bionic! Does it work okay with GSM carriers in the US?
I finally got to try it and unfortunately it didn't work for me. Mine is HW A '12 Bionic and I am on ICS. If I go outside my house and search for networks, I get to see only one network(not mine). I see extremely weak signal in the phone info screen and also it shows gsm out of service. I tried 3 sims from different operators. Inside my house, nothing ever shows up. In other phones, I get to see many operators. Seems like it's definitely a signal strength issue if the gsm 900/1800mhz and wcdma 2100mhz bands are not locked. I'm not sure at this point what is the real cause. I even tried flashing just the radios from GB versions as complete downgrading is supposed to brick the device. Needless to say it didn't help. I'm still investigating and experimenting.

Hi,
I have now tried everything possible with the Bionic to run it on GSM network in India but it has failed to respond. I tried both hardware versions and can confirm that it is not registered as a world phone like most of new Verizon devices.
The worst thing which still bothers me is how and why did it work once(Yes, I made and receive calls on Docomo network in India). It will still show network strength , detect network but not register. I cant find no answers to it and have given up on this. The model is now obsolete and is clearly not a world phone in my dictionary but I won't deny it having GSM capability having seen it work personally. I have finally dumped the other bionic as well.
Good luck with your experimentation though!
Hi everyone,
I bought myself a nexus 4 and I gave the P990 to my girlfriend.
I did a factory reset and inserted her SIM card (the mobile operator is called Free, a french operator), and I got a "roaming" symbol in the network. This was with the combination I have in my signature.
I've been trying different basebands today, and now I can't get any reception at all, it just says "No network".
Now I'm with DjangoManouch stock rom, 218 baseband, still no network with Free's sim card, but I tried with my sim card and it's working perfectly... I tried Free's sim card in my nexus 4 and it is also working perfectly...
I did get "normal" reception using the combination in my sig with free's sim card at a specific location... my best guess is that free's cell towers need a very specific baseband for it to work correctly? Do you have any ideas?
Thanks a lot in advance.
Cheers!
Slight update, the total network loss was solved by changing to the correct IMEI (it must have been reset by one of the flashes I did).
But the "roaming" problem is still there Manually selecting the network solves it temporarily. Has anyone ever had a similar situation?
Thanks!!
Did some more research... apparently her network has very limited coverage, and for the areas where it is not covered it has a deal with another operator, Orange.
So, whenever she doesn't have "official" coverage, she'll get the roaming symbol. And apparently they have an app to avoid people in the border to get reception from foreigner operators, which would mean "real" roaming, which is odd and interesting.
Anyways, hope it will help someone...
