APN Changing On Reboot - OnePlus 6T Questions & Answers

I just switch my provider to Total Wireless (which piggy backs on Verizon) from Verizon on my 6T, and I am having trouble with my APN. Every time I reboot my phone it reverts to the VZWINTERNET APN, ignoring the TRACFONE.VZWENTP one I saved previously. It has even reverted once or twice without a reboot. I have already spent 3 painful hours on the phone with Total Wireless, and they insist the settings are correct on their end, namely the CDMA-less feature. Despite their despairing customer service, I'm inclined to believe them because my wife has the exact same phone with the same OS version on the same plan, and hers works perfectly. I have tried creating a new APN, but I cannot as every other APN setting is greyed out, including the name field. I attempted to use adb to pull the /system/etc/apns-conf.xml file and change the APN through there, but since my phone is not rooted I have no way to write to the file. I would really like to not factory reset my phone, I would love some more ideas for me to try. I am running Android 9.0.17 build A6013_41_190911

Rogue Data Connection while BLANK apn is selected

Hi everyone. I have a problem that makes NO sense at all - but it's still a problem. Here goes:
As per recommendation of a number of people around here, and because I do not have a data plan, I have had two APNs for a while now: one was the real orange UK apn I use (let's call this "real") and the other, named "null" was empty (let's call this "fake"), so that I could switch between them and avoid paying most of the time. This worked perfectly up to...
The day I received an sms (perhaps mms? not sure) from 1550. As far as I know that's the number Orange UK spams its users from. There was the text "RockCorps" and a very small attachment (15kb I think). I accidentally pressed the "download" button but did cancel right after. I'm not sure if anything downloaded at all, but I didn't actually notice anything different, except...
My data connection was suddenly on. I could see the GPRS icon, and NetSentry also reported transmitted data. I checked the apn selection screen, which confirmed that my apn was still set to the fake one. But data was being transmitted!
So while I am using a fake, blank APN, gprs goes on and off as it pleases and transmits data.
I find this very alarming (and costly). I have tried to fix the issue by:
*selecting only 2G networks (to be safe)
*turning off always on mobile data
*turning off pretty much any phone setting that have to do w/ mobile data/GPRS.
*deleting ALL apns and re-creating them
*restoring apn list to blank factory setting and then reentering both apns.
NOTHING has worked. The phone still acts as if I have the real apn selected although the fake one is selected.
The ONLY method I've found so far for the phone to stop rogue GPRSing is to delete the real APN from the list. But whenever I add it again, without selecting it, the phone exhibits the same behaviour I describe above.
I'm clueless and a bit worried here. This is not making any sense, and the exact same settings I'm using now were working perfectly exactly up to the minute I opened the aforementioned message. Can anyone please help?
---further phone info----
HTC Magic, w/ cupcake, bought in Greece fully unlocked, with NO settings/added applications added by the carrier. NOT rooted.
Using it in the UK, on Orange mobile pay-as-you-go.
I had to enter mobile data settings myself: only entered GPRS apn (I'm not sure if that's a choice or up to the provider, but I've never seen any edge/3g icons up there).

[Q] Frequently lose APN / mobile data

Hello,
It seems I frequently lose my APN and Mobile data. Every 30-40 mins if not used, it's gone.
I have to go to Settings>More Settings>Mobile Networks>Access Point Names>APN (not set)>and type in: vzwinternet... a few seconds later it pulls the data and works fine. The next time I need it, gone.
I'm running Hyperdrive ROM at the moment but have tested Jellybean, Baja and a few others with the same issue.
I have reformated, deleted and wiped all rom slots in safestrap.
My search of this forum and of google yields me a previous issue similar to this on an LG from 2011, and google reveals people looking for APN settings but no real solution.
Any suggestions are appreciated.

its not big problem. if you can't access the apn then just use the apn of you prepaid.(your phone must be rooted and restarted). but knew that this phone gets the anp automatically.

It's not prepaid. It's not a big problem, just annoying. After I set the APN to vzwinternet, I save it. It still does not hold the settings. I am rooted, obviously, had have re-booted, and tried with other roms as well and have the same result.

Unlocked G900A on Verizon

Hey guys. I apologize if this has been addressed before. I did try searching, both XDA and the web in general, before posting this. I have a lot of experience with rooting, ROMing, bootloaders, kernels, Odin, etc. Basically anything associated with customizing a phone. Except for swapping between carriers, I've only done that a couple times and it only involved swapping the SIM and changing the APN. So I don't need kid gloves or a lot of explaining with potential solutions, like editing build.prop or flashing something either locally on the phone or through Odin. But anyways... here's my story, along with my thoughts on potential solutions to try (the only reason I haven't tried these solutions yet is because I don't wanna risk messing anything up):
I was given a Galaxy S5 for AT&T (model number G900A) about a week ago. I'm on Verizon and am currently using an S4 (coming from an S3 and Galaxy Nexus. So I've got a good deal of experience with Samsung devices. Although so much has changed between then and now, it's hardly relevant). So obviously the first thing I did was just throw my SIM from my S4 into the S5. Didn't work. SIM was locked (something I've never seen). Oh well, I didn't expect it to be so simple. The S5 was still on KK, so I figured I'd try a custom ROM to see if that affected the SIM lock. It didn't. So I ordered a SIM unlock code (a girl gave it to me who was given it by her ex boyfriend who didn't like the idea of her giving it to a different guy, so he wasn't exactly cooperative with unlocking it. No biggie, $24 was still well worth it). Since then, I've played with it a bit. I'm currently running TMS5 2.0. It's hard to form a complete opinion on a ROM when I don't have data/cell capacity and can only use WiFi. But with the small amount of experience, it's a nice ROM. I got my SIM unlock code this morning thanks to unlockunit.com. The SIM unlock I had purchased was estimated at 1-6 days and I received it in like 23 hours. I'd definitely use them again if anybody is looking for a place. Everything seemed to be going smoothly. Unlock was successful, added the APN settings, but the APN settings wont save. I've rebooted, cleared cache/dalvik, removed/reinstalled SIM, nothing worked. I figured I'd try a new ROM, but wanted to ask for some other opinions too. Also, when I had the thought to try a new ROM, I also thought that maybe a Verizon ROM would work on the Verizon network? But also figured it could not boot too, so I'd ask first.
Anybody have this experience with any solutions? Anybody else have any thoughts/ideas? I'd appreciate any input. Thank you
after hours upon hours of tinkering with it. I've made extremely slight "progress". Since I've been screwing with this all day, a lot of the time I'm doing something else at the same time. I noticed that when I had filled out the APN fields (listed below, so everyone can see what I'm using) and then turned the screen off and then back on, it would save and show on the APN list. But still didn't work. After looking closer, it was because when the screen turned off, the MCC and MNC changed from 310 and 012 into 311 and 480, respectively. I'm not sure why, but the APN editor automatically puts those numbers in every time I open the APN settings, but they obviously don't work. One time, in the grocery store, it actually saved correctly. The antenna bars showed correctly and the 4G icon showed for the first time. Then as soon as I left the APN screen to check the browser, they reverted, I went back into the APN list and it was gone again... this is incredibly frustrating
Name Verizon
APN: internet or vzwinternet
Proxy blank
Port blank
Username blank
Password blank
Server blank
MMSC http://mms.vtext.com/servlets/mms
MMS Proxy blank
MMS Port 80
MCC 310
MNC 012
Authentication type not set
APN Type internet + mms
So I switched from Twisted back to TMS5 2.0 to check the APN settings in it as well. And it has the same issue, MCC is 311 and MNC is 480 by default upon opening the APN editor. TMS5 also has "default,hipri" under APN Type by default.
Just for the hell of it. I decided to try changing those numbers 1 at a time and saving. The APN Type was the only one that allowed me to change it. As I expected. I'm going to give AllianceROM a shot now and hope it works, but I have a hunch that *IF* flashing a different ROM does work, it will be a KK ROM. But I'm giving it shot just because I can quickly flash with FF, rather than having to use Kies and SS. Fingers crossed...
as expected. AllianceROM didn't work. Next step, I'm going to try the stock rooted OC4. I *REALLY* hope this works. The idea of flashing back to KK from LP makes me uneasy. If anybody is reading this, and knows how to flash a G900A back to KK, or knows of a thread that explains it, I'd really appreciate it.
(I apologize to those of you who I'm sure are getting annoyed at what seems to be a solo conversation. I'm only trying to document each different step I've tried just in case there's someone out there going through the same thing that happens to stumble across this thread. In the off chance that it turns out that I can't discover something that *DOES* work, I'd at least like to document what *DOESN'T* work so they can save the time and effort. Considering that I've wasted 15 hours now on this **** already, I'd at least like to save anyone with this same problem that stumbles across this thread some of that time.
Anyways... time to flash OC4...
Dude, just unlock all the bands from the secret menu. Google it. Go to UE Settings/Settings/Protocol/NAS/Network Control/Band Selection and select LTE/WCMA.
To access the hidden menu, use the app Secret Codes.
Warning: The code to enter the menu varies from carrier.
APN isn't needed. The relevant apn info is already on your SIM.

Wow. I wish I knew that. I even called VZW and they told me that it only had a gsm antenna and was impossible to use on VZW. Well I took that, and T-Mobile's sale as a sign. I had kicked around the idea of switching to T-Mobile and selling my VZW unlimited plan ever since T-Mobile came out with unlimited data plans. Especially with no contract. It just seemed like the ideal plan for $80. Then they had the sale for $100 for 2 lines unlimited talk/text/LTE. Which was what my Verizon plan was for one line and only 450 minutes. Turns out my friend and his girlfriend thought the same and just switched to that plan. So they added me as a 3rd line. Unlimited everything for only $40/month is incredible. So before I sold my VZW plan, I ran speedtest just to see what the difference was. Obviously expecting T-Mobile to be at a disadvantage there. Nope. T-Mobile was 35.37MB/s down, 11.65MB/s up. Verizon was 10.12 down and 2.57 up. But I live in Phoenix, so it's a big city with small buildings to get in the way and mountains scattered throughout to put radio towers on. I'm sure the results would be quite different in rural areas. But for my situation, I can't ask for more. Unlimited excellent service for less that half of what I used to pay. Plus I got to cash out decently on my old VZW unlimited plan before they either bring back unlimited data or do away with AOL, which I think one or the other will happen soon.
All-in-all, I couldn't be happier with a free S5 with a better plan on better service for a much better price. And I've rooted the S5 and put TMS5 2.0 on it which runs incredibly. I was very nervous making the jump but am so glad I did.
I just wish I checked this thread before so I could have been able to confirm if that would have worked to put this phone on Verizon, or if it was stuck as GSM only as was the conclusion I came to after trying everything I could possibly think of, and listed in this thread. I'm gonna see if I can find a friend with VZW that'll let me give it a shot with their SIM just to hopefully be able to help anyone else with the same issue
Wow man heads up more people may give your their $.02 if they didn't have to spend 5 minutes reading each post!
The reason your data didn't work is because you didn't update the modem when you updated the system (by using the different lollipop roms)... If you had updated the modem, data would have worked.

Oh well. Live and learn. It's not that I enjoy typing novels, I just wanted to be as detailed as possible with what I was trying. It all worked out though. T-Mobile has better service in my area and I cashed out well from my VZW data plan. So I have no complaints with how it turned out I guess

APN Settings Issue

Hello,
When I originally purchased my Essential phone through Sprint, the phone had issues with sending and receiving text messages. I would receive multiple copies of the same text repeatedly, which was quite a nuisance. I discovered a fix on this forum that involved a custom APN setting, it worked like a charm.
Following a subsequent update, that custom APN became problematic and I could not connect to mobile data as a result. This was easily corrected by switching back to the original APN. My phone treated the custom APN as the default, so I would periodically have to switch it back. Annoying, but no big deal.
HOWEVER, after the most recent update I've found out that the developers, in their infinite wisdom, decided to lock the ability of the user to edit APN settings.
Now, my phone is locked into a default custom APN that does not allow me to access mobile data.
Does anybody have any advice for how to resolve this issue? Is there a way to completely reset my APN settings, or am I screwed and the only option is to reset the phone to factory settings?

Mobile Data won't turn on

I've been having an issue for about a month now. The mobile data will not turn on no matter what I do. I can join WIFI and browse just fine though.
My phone is Oneplus 6t Mcclaren edition. About phone is showing it's an A6013, even though my provider is Verizon. Could that be an issue? Again though, this only started a month ago.
I have tried doing all the recommended fixes on most forums, reset to defaults, reinstall sim, etc.
Dialing ##UPDATE# gives me "USSD code running..." and then "Connection problem or invalid MMI code."
I'm running Lineage 17.1, Dec 3rd 2020 release.
I was considering just restoring stock ROM and seeing if that fixes things. Does that sound like the best next step?
@jaegercng
I used to use a CDMA carrier (Sprint) back in the Nexus 5, Galaxy Nexus days but quickly learned gsm is the one to have if you are in to modding Android because that's what most the world uses and everything was/is always more "out the box" compatible if you had a gsm carrier. Does Lineage 17.1 support Verizon?
You can try the old apn xml data fix that's been around for many years. Just
delete your /apns-conf.xml/ file in your /system/etc/ and also in /system/product/etc/ and replacing only the one in /system/etc/ with the one I'm attaching then set permissions on the new apns-conf.xml file to 0644 using root explorer or whatever you use that can access root directories on your device. After that go to settings/networks and internet/mobile networks/access point names/ in top right hit the three dots, select "reset to default" apn , your data will come on then, "if it's an apn issue." If and when LTE shows up in your status bar just reboot system once and you'll be good from that point onward. For your data/LTE to come on after you reset apn to default it shouldn't take more than about two minutes. This could very well be it. You could have maybe installed an update at some point that had the apns-conf.xml file wrong. You could also maybe have a messed up sim.. I use metro by t-mobile. When metro was metro pcs before t-mobile acquired them they were great. Now I have times my data/LTE just isn't present at all. I toggle airplane mode on and off so I can get my data to work or when they throttle the hell outta me. Hope this helps. It's worth a shot.
