Solution: Prepaid APN change after ICS upgrand

(MODs: Please excuse if this is in the wrong place. I am currently only working with the Atrix 2 after ICS so I didn't want to push this on anyone else with other devices unless someone could confirm this works across all ICS ATT prepaid devices)
This is for those who would like to use their Atrix 2 ICS (probably any other ICS device) on AT&T prepaid (Pay as You Go) service.
I was using a 3G Moto Bravo for years with the $50/month unlimited talk/text prepaid plan with $25 data plan.
After purchasing the Atrix 2 and upgrading to OTA 2.3.6, I was informed by ATT cust. care that "4G Devices will never be compatable with prepaid service."
I used APN Backup and Restore, to backup and delete all APNs and added the APN below for flawless 3G ONLY data and MMS.
After upgrading to the ICS leak, I found out ther ICS will not allow APNs to be edited by 3rd party apps, and the user still cannot remove the stock APNs, even if rooted.
SOLUTION (REQUIRES ROOT):
1.Purchase Root Explorer from the Play Store.(there may be free solutions to view/edit .db files. let me know so I can update this)
2. Make a backup of: data/data/com.android.providers.telephony/databases/telephony.db
3.Purchase SQLite Editor from the Play Store
4. Remove all 'records' from: data/data/com.android.providers.telephony/databases/telephony.db
5. Go home -> Settings -> More -> Mobile Networks -> Access Point Names -> New APN
6. Enter these settings for your new (only) APN:
Code:
Name: ATT
APN: wap.cingular
Proxy: Not Set
Port: Not Set
Username and password are blank
Server: Not Set
Mmsc:h t t p : / / m m s c . c i n g u l a r . c o m (remove spaces)
Mms proxy: w i r e l e s s . c i n g u l a r . c o m (remove spaces)
Mms port: 80
Mcc: 310
Mnc: 410
Authentication type: Not Set
APN type: default
(please note that "Not Set" means that you do not put any data in this field.)
This may require a phone restart in order to work, but you should at least be able to access 3G data over a prepaid account. NOTE: You must have any data package for this to work. The "unlimited data" that is included in the plan does not apply to smartphones.
This is my first post, so I apologize in advance if I have broken any forum rules. I simply could not find a solution to my problem anywhere in internet land, and I wanted to prevent others from spending the 6 hours I did to get this working, or being totally disappointed to learn their new 4G device will "never be capable of running on prepaid networks". This is a lie ATT uses to make money. I would be happy to edit the post to clarify or help anyone who would like more details.

Thanks for the post!

Ummm or go to the apns and Menu, add new, save done.
This is entirely unneeded. I use straight talk just fine and all I did was add an APN same with att prepay.

I wish it would have been that easy. That was the first thing that I tried. (Many different ways and combinations)
I have some similar issues with customers whenever I worked for an AT&T authorized reseller, but non android devices.
However, in this case, either the network lock or some other policy in Android prevents the removal of the existing APN,s and upon entering a new APN and rebooting, the APN would disappear.
I would not have gone through a half a day's work to get this functioning properly if it would have been that easy. I'm not 100 percent sure exactly what is going on but I will give my best under standing of the situation. I was using an AT&T branded stock Atrix 2. I have been using my AT&T prepaid SIM card in a 3G device. Upon moving to AT&T SIM card to the Atrix 2, it automatically loaded 3 APNs from the Android telephony database. Those 3 have the lock symbol next to them and could not be edited or deleted, nor would a new manually entered APN stay after a reboot. when I was on Gingerbread I was able to use APN backup and restore to delete all records in the database, and only then did it allow me to add a new 1 by using the "add new" button.
. My experience with using another Gsm provider similar to straight talk, was that whenever I insert a SIM card I noticed that there were no APNs in the device by default for that network. This meant that I was allowed to add a new APN with no problem.
So, depending on if your device is branded by a particular carrier and or if android has existing APNs in its database for the service provider you are using you may have not had any trouble at all.
The conclusion I'm coming to is that you can normally just add a new APN unless there is a conflict such as the AT&T modern vs legacy access point names.
I only hope that this post will not get in anyone's way, and possibly might prevent someone hours of misery or giving up.

Ohhhh okay. I see what you're saying now. Gotcha

I've had my wife's Atrix 2 (on ICS leak, of course) on H2O and Net10, and both times all I had to do was add the APN normally. The APN should be att.mvno though, and get rid of the mms proxy and port, those can actually make MMS *not* work. Just make sure you name it something other than ATT or any of the listed APNs.

APN issue
How do I remove the following:
Remove all 'records' from: data/data/com.android.providers.telephony/databases/telephony.db
I was able to fine the above path using root explorer, but when I run SQLite Editor I am not able to see above file that you asking to remove.
HTC Rezound- Root with S-ON
Thank you

i deleted all entries, and the pre locked AT&T APNs are now gone, but there are no options to add any new APNs.
Is there a way to add an APN manually or restore the option to add an APN?

Did you try editing the apn.conf in /system/etc ?
You should be able to add/remove any apn you like, once you're done go to mobile network settings > access point names then hit the menu button and reset to default. That should load the apns from your apn.conf file and hopefully you'll be good to go.

Great seems to have worked one way or another. Thanks! I managed to add a new APN (straight talk) and data seemed to work for a few minutes, but after powering down and powering up, data has once again cutoff and will not come back on.
The 4G symbol is there but it won't turn blue or show any data transmission. I've tried a factory reset and add/delete the APN that worked, but still can't seem to get the data to go up or down anymore. Calls and regular SMS still work.
Pretty sad over that tease after days of banging m head against the wall...:crying:
Any ideas anyone?

Are your apns still set to what they should be? Have you tried turning of your wifi and sending yourself a mms msg? That's usually the best way to test whether apns are working or not.

Yeah, the APNs are the correct APNs. MMS won't send or receive. I actually unlocked the phone and played with the settings and that seemed to fix things. I though the phone had somehow relocked itself, but other carrier SIMs seem to work in the phone now.
The display is showing 4G access but there is no data transmission. Even after deleting the APNs the 4G symbol does not disappear and readding it has no affect.
It was working for a bit just yesterday, but I cant seem to get the phone to transmit any data up or down since then.

What settings did you mess around with? Also, a straight to the point solution would be to call the provider and get the proper apn settings (if you haven't already). If your 4G is lit up, but you can't push or pull data, then you might have an auth value wrong, or a proxy wrong, etc. If you haven't already, call and get the apns straight from the source.

Sprint LG V20 Free Hotspot

You can PROBABLY do this without root IF you can coax Sprint into giving you your MSL code, go to the dialer and type ##3283#, going to APN Settings and hitting edit.
THIS method, however, only works if youve ran DirtySanta and rooted your device. I saw a few threads of ppl asking how to get it working so....here's how i did it.
Go to Settings-->Networks-->More-->Mobile Data-->Access Point Names-->Add APN
Name: Sprint LTE 2
APN: n.ispsn
MMSC: http://mms.sprintpcs.com
MMS Proxy: 68.38.21.7
MMS Port: 80
MCC: 310
MNC: 120
APN Type: default,mms,supl,dun,hipri
APN Protocol: IPV4/IPV6
APN Roaming Protocol: IPV4/IPV6
Leave everything else untouched
Hit Menu-->Save
Select the new APN you just created
Turn on hotspot
For some reason, after you turn on hotspot you may have to manually set the DNS on whichever device you're using to 8.8.8.8 otherwise the internet doesnt work. Not sure why that is, but after i did that, my hotspot works.
If youre using an android tablet with your hotspot and have to change the dns(you'll know because it'll say you're connect to the hotspot but you can't browse any websites), then on your tablet go to your wifi settings, long click on your hotspot youre connected to, click "show advanced options" and change Dynamic to Static (may say manual). After that, scroll down and change the setting for DNS 1 to 8.8.8.8. Should work after that.
I used to use hotspot a lot about a year ago with my note 5(7-10 gb/month average) and never got dinged for it. I would think that if you're cool about it youll be ok. I cant say that FOR SURE but I've never had issues.

Just for the record. I tried everything before rooting. I paid off my phone so they couldn't deny me my MSL. The options are simply missing after entering your MSL code. You can see everything with ##DEBUG# (can't remember the numbers ) but they made sure to remove the option when I used ##3282#. This was the Main reason why I rooted. After rooting it didn't work so I had to figure it out.

I attempted without root and the options were not available for the most part and what little they had, most can't be edited even when I imputed my MSL. Sprint made sure that it wasn't possible without root. There is no add apn option.
After root, I immediately tried to use hotspot and it connected but my devices couldn't get internet services. I asked for help but me2151's hotspot worked well so I figured that I was on my own. I remember adding dun on my lg g4 so I tried the codes but I couldn't get any of the codes to even register on my newly rooted phone.
I finally found the found those setting by searching and saw that "DUN" wasn't there. I then made a new APN with the existing settings but added DUN and it worked so I posted it.
By the lack of responses, I figured that almost no one had the problem.
BTW, how did you figure out adding the apn would work? I remembered a post on the LG G4 forum over a year ago and tried it for this phone.

Sprint Hotspot Fix (not passing data to connected devices)
The following is the fix when you can connect to the Hotspot but get DNS errors or no data being passed to connected devices.
Sprint prevents you from editing your APNs
You can change permissions on your telephony db with this command:
adb shell
su
chmod 666 /data/user_de/0/com.android.providers.telephony/databases/telephony.db
Grab the ID of your current APN using the following command:
adb shell
content query --uri content://telephony/carriers/preferapn
If the type doesn't contain "dun", copy the existing type string and add ",dun" to the end:
In the following command you would substitute
your current type string for "your_type_here",
and the _id for your_id_here:
adb shell
su
content update --uri content://telephony/carriers --where "_id=your_id_here" --bind type:s:your_type_here,dun
Example
adb shell
content query --uri content://telephony/carriers/preferapn
Output
Row: 0 _id=656, name=Sprint LTE internet, numeric=310120, mcc=310, mnc=120, apn=n.ispsn, user=, server=, password=, proxy=, port=, mmsproxy=68.28.31.7, mmsport=80, mmsc=http://mms.sprintpcs.com, authtype=-1, type=default,mms,supl,hipri, current=1, protocol=IPV4V6, roaming_protocol=IPV4V6, carrier_enabled=1, bearer=14, bearer_bitmask=0, dns1=, dns2=, ppp_dialing_number=ppp_dialing_number, defaultsetting=1, usercreatesetting=0, sim_subscription=0, inactivetimer=0, mvno_type=, mvno_match_data=, sub_id=2147483643, profile_id=0, modem_cognitive=0, max_conns=0, wait_time=0, max_conns_time=0, mtu=0, edited=0, user_visible=1, touch=0
adb shell
su
content update --uri content://telephony/carriers --where "_id=656" --bind type:s:default,mms,supl,hipri,dun
I ran into this issue on my Pixel XL and was helped by @Fenny to come up with a fix

do u need root?

Seems to be that you do, his post above said that without it he was missing the ability to edit parts that needed to be changed. I have yet to see a version of these edits for hotspot provisioning that didn't require rooting to be able to edit the appropriate files.

thank you everyone, you need root to edit the APN settings. I'm waiting a solid method to restore to stock before I root. again thanks everyone for their effort.

I realized you couldn't edit the default apn for Sprint so i created a new one since i was already rooted to see if it would work

hey guys just an FYI, you don't have to go through all the trouble of making a new APN setting and stuff like that which is quite frankly a pain in the ass; get shortcut master (free version is fine) from play store. Open it and from the menu tap search, and let it load a sec. Search for "APN" and look near the top of the results for the "ApnUnlock" intent from hidden menu. Tap it's choose the far left Launch method button. The next screen will let you unlock APN access, you just tap the button, you can't miss it.
After its unlocked, launch the ApnSettings intent two lines down in the search results. You can now edit the sons you already have (just add ,dun). That's all it takes. If that ApnSettings doesn't do it, scroll down a page and choose the vzw one, its never failed me once yet through 4 LG phones.
My hotspot works now like it should, I never had to change any DNS settings or anything like that. Zjyst Unlock, then add ,dun to end of the APN type line.
P.S. this method requires root, Im unaware of any way around that, unfortunately

If anything. That is the EXACT program that I was looking for. A shortcut maker but with root access. I use shortcutmaker but it always says that it needs permission. This one asks for permission. Thanks.
This is a far better way too. I did the whole apn thing a few weeks back because I didn't know of this program.

Does anyone know if this counts on the 5gb data free hotspot or is it simply unlimited ? I have the unlimited plan and it includes 5 gb free hot spot.

Hotspot bypass for rooted Nougat - MSL Needed

If I have inadvertently re-created another's work I apologize. I did not find this method in any of the closely related threads but it's so simple it should be there somewhere. Let me know and I'll gladly give credit where credit is due. That being said here we go
OK, Quick and dirty as usual...How to get working hotspot bypass on rooted nougat. It works on initial root or you can edit the build prop back to 310000 n reboot. Okay, so more or less follow the rooting method in godpowerrr's thread unless you're already rooted then pickup at the adding APNs below:
https://forum.xda-developers.com/sprint-s7-edge/how-to/sm-g935p-spr-root-nougat-7-0-data-t3568780 Thanks be to @godpowerrr
Follow all the steps, except just leave wifi on while you run through the process.
When you get to the steps with the build.prop edits don't do it yet.
Go into settings-connections-Mobile Networks-Access Point Names: click "add" in the top right.
Add this APN;
Name: Whatever you want to name it.......LTE HOTSPOT
APN: n.ispsn
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: http://mms.sprintpcs.com
Multimedia Message Proxy: 68.28.31.7
Multimedia Message Port: 80
MCC: 310
MNC: 120
Authentication Type: not set
APN type: default,mms,dun <-----no spaces after commas
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
Turn APN on/off: APN tuned on
Bearer: LTE
Mobile virtual......: none
Mobile virtual.....: not set
NOW CLICK SAVE AND IT WILL DISAPPEAR- don't worry, it'll re-appear later.
now go back to the root guide and pick up where you left off changing the build.prop values. when you change to 310120 the new apn will populate.
This is where you need the MSL- manually select the new APN you created. Either way you should have a full functioning hotspot.
To sum it up you can add a Custom APN by changing the build.prop, creating the APN, saving, and changing it back. Have fun
Better method here-

I'm trying to bypass the tether check for an AT&T S7 (G930A) on Nougat... You happen to have any insight on how to port this process?
Thanks for the info, I'll do some research myself to see if I can get anywhere with it.

1st look at your normal LTE APN and write down all the info.
I'm not sure exactly what at&t has for the equivalent of ro.cdma.default_numeric but I would suppose it has something similar. search for the combined combination of your MCC and MNC. that's the number you'll want to change. as you can see from the OP, sprint is 310, and 120. so the combined numbers are 310120. you'll see the numbers when you look at your APN.
edit the build.prop line to 310000. reboot and go through the op steps to create(add) an identical APN to the one you wrote down. settings-connections-Mobile Networks-Access Point Names: click "add" in the top right. The only changes that would be made would be the name of the APN and the addition of dun to the APN type line. everything else will look just like your stock APN from earlier. make sure to click save and it will disappear. then change your build.prop line back to what it originally was and reboot. it should show up in the list of your APNs now. then, using your msl and ##data#, go into apn settings and select the new apn you created. Hope it works. pm me if you run into roadblocks, also i'd like to know the build.prop/APN info if there are issues.

1st look at your normal LTE APN and write down all the info.

Seems as though AT&T handles DUN provision checks in a fundamentally different way... Couldn't find my MMC+MNC string in build.prop.
Ended up getting a solution here @ https://forum.xda-developers.com/showpost.php?p=71547500&postcount=4
Thanks for the reply!

Hey, thanks for posting this method, worked for me.

Does this unthrottle the hotspot as well? Lol. Do you have any information on how to unthrottle the data speeds? Sprint has me throttled to 1mb speeds when i should be getting around 60mb/s.

Honestly I have no idea how sprint does their throttling. I can't say I've ever been in that situation. Give it a shot, see if it has any effect

OK, Quick and dirty as usual...How to get working hotspot bypass on rooted nougat. It works on initial root or you can edit the build prop back to 310000 n reboot. Okay, so more or less follow the rooting method in godpowerrr's thread unless you're already rooted then pickup at the adding APNs below:
https://forum.xda-developers.com/sprint-s7-edge/how-to/sm-g935p-spr-root-nougat-7-0-data-t3568780 Thanks be to @godpowerrr
Follow all the steps, except just leave wifi on while you run through the process.
When you get to the steps with the build.prop edits don't do it yet.
Go into settings-connections-Mobile Networks-Access Point Names: click "add" in the top right.
Add this APN;
Name: Whatever you want to name it.......LTE HOTSPOT
APN: n.ispsn
Proxy: not set
Port: not set
Username: not set
Password: not set
Server: not set
MMSC: http://mms.sprintpcs.com
Multimedia Message Proxy: 68.28.31.7
Multimedia Message Port: 80
MCC: 310
MNC: 120
Authentication Type: not set
APN type: default,mms,dun <-----no spaces after commas
APN protocol: IPv4/IPv6
APN roaming protocol: IPv4/IPv6
Turn APN on/off: APN tuned on
Bearer: LTE
Mobile virtual......: none
Mobile virtual.....: not set
NOW CLICK SAVE AND IT WILL DISAPPEAR- don't worry, it'll re-appear later.
now go back to the root guide and pick up where you left off changing the build.prop values. when you change to 310120 the new apn will populate.
This is where you need the MSL- manually select the new APN you created. Either way you should have a full functioning hotspot.
To sum it up you can add a Custom APN by changing the build.prop, creating the APN, saving, and changing it back. Have fun

I have completed the whole process and was able to enter the new VPN. However, when changing the buildprop back I am unable to select the new access point. I have tried the ##DATA# and nothing happens. Any ideas?

Not sure why the ##data# dialer code wouldn't work unless you rooted at the same time and possibly missed a step or disabled the app it triggers. Make sure you click "save" after you have the new APN all written up, then it will show up when you change your build.prop back to 310120. Also make sure your editor has been granted root permissions. Just throwing a few things out there, there are so many little things you could've possibly missed.

It turns out, I'm pretty stupid. Apparently didn't know how to spell DATA. That or it just started working randomly. However, when testing I still get "You have not subscribed to the Hotspot service"
I've checked and after the ##DATA# and entering my MSL I'm able to select the custom APN. It just wont allow tether. I don't know if it makes a difference, but I'm rooted on 7.0 Nougat S7 Edge

double check the apn you selected, once you have the "dun" segment there it shouldn't say that. also might want to throw in a full powerdown and reboot, might be residual.

Thank you for the help. Without it and your guide I wouldn't have gotten it working. I combined your guide with another (both had different settings) and found a combination that works for me.
If anyone is having issues like I did, follow izzibew26's original guide, but instead Authentication Type: not set change to Authentication Type: None

MMS Failing to Send / OnePlus APN Settings Grayed Out and Can't be Edited - Fix

This is one for the search engines since I couldn't find an answer for this out there for this so hopefully this helps someone else.
My MMS messages were suddenly failing to send. I took a look at my logcat and saw that for some reason even though the MMS service was pulling the correct MMSC from the profile, the OkHTTP API was failing to connect to localhost. My only guess is that apparently the MMSC http URL was sending an HTTP redirect to something that my device was resolving to localhost since I could connect to the MMSC with my web browser and ping it successfully by name with a terminal client without it resolving to 127.0.0.1 (localhost). I tried disabling my ad blocker since that's the only thing I could think of that could be causing a DNS resolve to 127.0.0.1, but that wasn't it.
I also knew that my MVNO had updated their MMSC and so I tried adding in a new APN with those settings, with the new MMSC entered both by name and by IP address (note: with OnePlus you always need to specify an MVNO type, in my case GID, for a custom APN to save). From the logcat, I saw that the MMS service was unbelievably still using the grayed out APN profile with the old MMSC, even after a reboot. I verified that my custom APN was in fact selected. I tried deleting the storage from several different phone services, as well as locating and deleting the custom APN file, to no avail.
Finally, I figure out what was going on. OnePlus has an evil APN locking file at:
/system/etc/apns-conf.xml
If an APN name on your SIM matches with an APN name in this file, then you are locked to that APN even if you have defined and selected a custom APN!
So, I made a backup copy of this file first, then I located the grayed out APN profile in this file (search by APN name), deleted it, and rebooted. Looking at the logcat though, I still saw that the phone was not using my custom APN profile!! It turned out that there was a second match for the APN name in this file. I deleted that as well, rebooted, and voila - no more grayed out APN in my APN settings that I'm locked to and can't edit. I verified in logcat that my phone was now using my custom APN profile and now my MMS are working again!
Hope this helps someone else!
Notes:
I'm using the last Oreo/ OxygenOS 5.1.11 for best xPosed support, but I did see on the OP forums that other people were having issues with their MMS and APN grayed out even with Pie on several different OP phones.
Yes, I have an older SIM from my MVNO, but not that old

APN Settings : APN Type "dun" not Allowed? - China Version

Anybody run into this setting up their APNs for dual sim...
I found a program that allows the APN to be inputted, but for the particular carrier for my second sim (Visible, MVNO for Verizon), its not allowing for APN Type the following:
default,dun,supl
I've seen that some other phones you need to input "dun" as "DUN" in capital letters. Just curious if anyone ran into this and if this is the fix. Just trying to save some time if I have to look for another solution....
Thanks as always!!! :good: :highfive:

I have same your problem for fix it you must to make default name MI and remove any another in access point names
