[Q] Automatic APN switching? / Do I need to manually change APN while roaming?

Hi, I've just flashed the Android Revolution HD 3.3 rom and 12.41.60.19_26.06.04.14_M radio.
I noticed that I was not able to use data connection until I manually enter the APN for my network provider.
Back when I was using the stock rom, it used to load APN settings automatically when I put in the sim card (I have two sim card from different networks, when I switch the cards, the APN settings changes automatically). I was wondering if there's anyway to make this rom do the same thing?
If not, this is not a big problem when I'm in town, as I can enter both networks APN and choose them manually instead.
However, will I'll need to research into APN for other networks before I travel? What happens to the APN settings while I'm on roaming?
===
Edit: In case this matters: I am in Hong Kong, using CSL and 3.
Edit2: both provides are in the apns-conf.xml file, somehow the APN still aren't switching automatically

How to Flash ROM and keep same Data plan?

Hi Guys.
I'm trying to understand how to guarantee the same data plan after flashing a new rom. (Desire HD)
On Windows Mobile it meant having to write down and remember the Access Point and password and manually type that in the phone once you've flashed a new rom.
What should we do with Android or what are the only things to look out for?
Where is this info stored? Is it in the SIM Card? Is it to do with the Baseband version?
I'd really appreciate any info you know about this.
Thanks.

Most, if not all custom ROMs have a huge APN list that will default to your network.
You can find your details in Settings > Mobile Network > Access Point Settings, (Or something like that, I use MIUI so it may be a little different)
I wouldn't worry about having to backup yours as it will be in the APN list.

Thanks andyharney.
My APN isn't listed in CM7 which is the first rom I've tried.
It is also locked so I wasn't sure what it was.
With the app APN Backup & Restore we can save the APN details as an xml file to the SD card and then read that xml file or restore the APN from that file.
I'll pass that APN info to the CM team.
Cheers mate.

Docomo Arc adding APN failed (but I got a semi solution)

Dear all,
I have flahsed docomo's rom for the ARC on my HK branded ARC, and for some peculiar reasons, when I tried to add an APN for my provider, which has a different MCC and MNC, that APN will not save on the phone. If you used the default MCC and MNC as the Japanese APN's, it will stay there but as soon as you change those settings that particular APN will disappear.
Out of desperation I went to the market to see if there are any APN apps that can force save a setting. I thus downloaded APN manager and it worked for I can, through that app, choose the APN I wanted to use and it will work!
However, if you go to setting by pressing the menu button to see the list of APNs stored in your phone, the one that is saved using the APN manager will disappear and you have to redo it again... So you cant open the APN menu under network settings... very queer...
But at least I have a semi solution for now, and I have no idea why the docomo ROM runs smoother than the official HK 2.3.3.... But unfortunately, it is only a 2.3.2 ....

Proper Wifi Tethering Instructions - T-Mobile Samsung Galaxy Note 2

Please note that this is NOT my guide, I just simplified it into very easy terms and instructions, but original is by the great WarLockW
Steps to take:
01. Have a T-Mobile T889 Samsung Galaxy Note 2
02. Download these files: http://forum.xda-developers.com/attachment.php?attachmentid=1446771&d=1351716949
03. Extract files to folder on Desktop
04. Root your T-Mobile T889 Samsung Galaxy Note 2
05. Once rooted, make a COMPLETE backup using CWM or Titanium Backup (I did BOTH just in case, I like to be double sure I have a backup)
06. Once backed up, go to Google Play Market and download "APN Backup & Restore"
07. Once installed, open APN Backup & Restore and press on "OK" on the warning message that comes up
08. Close APN Backup & Restore (from task manager too, just in case)
09. Open Titanium Backup and press on Backup/Restore
10. Find the application "APN Backup & Restore" and long press with your finger on it
11. Once menu comes up, press on "Convert to System App"
12. Once done, close Titanium Backup (from task manager too, just in case)
13. Open APN Backup & Restore and press on "OK" on the warning Message that comes up
14. Press on the menu button on the phone and press on "Disable ICS Check"
15. Close APN Backup & Restore (from task manager too, just in case)
16. Open APN Backup & Restore and press on "Backup APNs"
17. Select a name or leave the one in there
18. Once backed up, close APN Backup & Restore (from task manager too, just in case)
19. Connect your phone to your computer
20. Once connected, navigate to your phone drive in My Computer and go to "Phone > ApnBackupRestore" > Copy the created XML file to your computer (once again, just in case)
21. While still in the "Phone > ApnBackupRestore" folder copy/cut/paste the "T-Mobile-APN.xml" file to that folder
22. Once the file has been copied to the "Phone > ApnBackupRestore" folder, open up APN Backup & Restore application on your phone
23. Once open, press on "Delete APNs" and press "Yes"
24. Once deleted, press on "Restore APNs" and select the T-Mobile-APN.xml (the one we originally copies from the zip folder that needed to be downloaded/extracted to a folder on your Desktop, and press "OK"
25. It will then restore the newly modified APN file
26. Close APN Backup & Restore (from task manager too, just in case)
27. Go to Google Play Market and download "Tethering Widget"
28. Once installed, go to the APPS icon on your phone and select Widgets tab on top and drag the Tethering Widget to a new page
29. You should now be able to successfully enable native tethering via the Widget
30. MISSION COMPLETE
*NOTE: DO NOT GO INTO THE ACTUAL T-MOBILE HOTSPOT APPLICATION AS IT WILL OVERWRITE THE APNS AND TETHERING WILL NO LONGER WORK. IF THAT HAPPENS, REPEAT STEPS 23-30.
Please let me know if I have missed anything. Alot of these steps are self explanitory but I have had issues with this the past day, but I finally got it to work so I wanted to share every step in an ultra-easy fashion

Isn't this the same step as WarlockW instructed?

Indeed, but it is modified a bit since "insecure boot.img" is not required, but I totally did forget to credit him. Original post has been updated. Sorry guys, mean no disrespect nor tying to take credit for anyone elses work.

Thanks so much. I'm typing on my tablet tethering from my phone. It's working great so far.

I believe so, just make sure you have ROOT already done and if you have Root Explorer, I suggest just copy the contents of the download zip file on to your sd card and you can go through there, as long as you have all the files, you should be able to if I am not mistaken. I am pretty computer savvy, but I have been out of the android world for a few years, coming from an iphone 4, so this is sort of all new to me, but i do believe you should be good to go without a computer. The zip file contains the T-Mobile-APN.xml along with the APK so you should have it all

The quick and dirty is. Grab tmobile.xml from the OP.
Install APN backup.
move APN backup to /system/app from /data/app. You can do this by moving and changing permissions to 644. then rebooting. //don't titanium pro
delete all apns, after backing up. And restore the one from the OP.
Use settings>mobile hotspot and enable hotspot.

do u need titanium backup pro for this? or just free version?
Edit: ok nvm got stuck at the system app step with just the free version..

Yes, that feature is part of the PRO version.

If you got it to work but need to change the password of the hotspot now
go to the notification bar, go into the hotspot settings
do not click on On/Off (it should now be on from the widget)
click on the Hotspot name (Mine was Samsung Galaxy Note II 13)
Then click on Configure (lower right)
and in there you can set the password to be whatever you want
save settings
and you should be good.

Another Question?

I did that as well, turn security off and logged in but it directed me to Tmobile page asking me to do an upgrade on my plan for tethering and using their hotspots, so I just went back to my wifi instead.
Is there a way to bypass that page and go straight to surfing and etc.?

Go through steps 23-30 again, delete the APNs and restore the T-Mobile-APN.xml file from the original zip.

[Q] Editing MMS settings under a JB rom

First off my disclaimer -- I have searched the forums already for an answer, but can't find anything that I understand to be analogous to my problem. Also, I'm kind of a noob about this but I've been a unix/Linux sysadmin for 20 years so I have some understanding of what's going on at the Android operating system level; just not the CDMA piece yet.
So here's what I have:
I flashed my E4G over from Sprint to Boost using the Incognito method. Changed the MMSC URL through the dialer with my SPC. Voila! Everything works great.
Except that I'm on FC09 Gingerbread and it's boring.
SO... I root the easy way by flashing that pre-rooted FC09 BML image that's floating around here and install CWM recovery. Easy. Everything's cool.
Then, I wipe everything three times (no, I'm not anal retentive or obsessive-compulsive) and flash the Carbon JB rom from recovery.
Flash works perfectly and now I have TWRP for recovery, which is very convenient, though I gotta give props to the ClockworkMod team, they have knocked down a thousand walls.
BUT--- My MMS stopped working because the mm.myboostmobile.com MMSC URL was overwritten with the one that was baked into the ROM (I guess from the romdev's phone that was used to make the image). Anyway, Now that I'm on a Jelly Bean rom, I can't just use the *#*#DATA#*#* dialer code and my SPC to edit the setting back to Boost because I get that damned MODEM EXCEPTION error (which I think is related to permissions changes under ICS and JB that weren't there in FC09 Gingerbread).
I bought an APN manager off the play store and did a backup of my APNs under the working stock setup, but of COURSE, the damn thing doesn't work under ICS or JB so I wasted my money there. AND, APN Backup and Restore from the play store doesn't work properly either, although I can't rule out the possibility that the APN backup I took under working FC09 was no good.
So, my questions are these:
Is it possible to manually edit the appropriate APN settings under a Jelly Bean based ROM back to boost? I'm assuming there's some xml file somewhere that holds all this stuff that I could just vi ? I know I just need to null out the proxy and port values and switch the MMSC url back to mm.myboostmobile.com right? So where is the file and if there's an easier way to do this, can you give me a pointer?
Thanks! I really don't want to be stuck on Gingerbread just to be able to drunk-text dong shots to my boss at 2am.

SOLVED!
UPDATE: ok, a few more hours of archeology and I figured out how to get the right MMSC URL poked in there. It was an inelegant hack:
1). After moving APN Backup and Restore (play store) to my system folder with system/app/mover (also from the play store), I backed up my APNs.
2). I copied the backup XML file onto my PC and edited it with vi to change the MMSC field in each of the 15 APNs stored in the file to "mm.boostmobile.com" THIS IS PROBABLY OVERKILL and I might have broken something else I don't know yet by doing this
3). Copied the edited file back to the APNBackupRestore folder on my phone's SD card
4). I used APN Backup and Restore to delete all my APNs then entered the dialer code to view my MMSC URL, it gave a FC error --I knew it was empty now.
5). Rebooted into TWRP (CWM would work the same way) and wiped cache, Dalvik, then fixed permissions for the hell of it
6). Reboot into system, restore my edited backup APN file using APN Backup and Restore
7). Reboot again
8). Re-enter the dialer code (*#*#3282#*#*) and view my MMSC URL: Voila! "mm.myboostmobile.com" is in there now
9). texted a close-up of my big toe to my wife at her work and received a reply txt with a close-up of her left nostril: SUCCESS!
Now MMS and 3g (on rev a8) are working just fine on CarbonRom. Hope this helps someone.
