No Mobile Data - Help please!

Hi All,
I got my Note 2 today, and have run into a problem already
Mobile data (HSPA+) was working when I first got the phone and used it between the shop and the way home.
When I got home, I switched over to wifi to download things.
I then flashed CWM from the cwm-root-note2.tar.md5 file in Dr Ketan's guide using PC Odin.
Then, I flashed Omega v3 via CWM.
All went without a problem.
I was still on wifi and downloading and installing all of my apps.
After a while I turned off wifi and I noticed that I wasn't getting any mobile data connection. I was getting 3 or 4 bars of mobile signal, but no 3G, H or H+ symbol to indicate mobile data.
I messaged a nearby friend on the same carrier and he said his was working fine. So, I figured I must have messed up the mobile network settings,
I checked the APN settings and they were blank, so I put them back in manually.
Still no data connection,
I went into CWM and wiped cache, dalvik and user data.
Still no good.
I downloaded the stock XXALJ1 ROM for Thailand (where I am) and flashed that, did another 3 wipes, but still no luck.
I tried doing a factory reset from the settings menu. But still no joy.
I put the SIM card into my Note 1 and it got a H+ straight away and data was working fine.(when the shop cut it down, they made a nice neat job of it, so the excess makes a decent micro sim holder). So, the network and SIM card are OK.
I noticed that when I first got the phone, the boot screen said "N7100" under "Galaxy Note II".
Now, it doesn't. I'm not sure when it changed.
I also noticed that when I do the under/factory resets, there are still some settings that aren't reset, For example, I set it to WCDMA only to see if that helped and then when I did a factory reset, it was still set like that, rather than the default "auto" that it originally comes with.
Unfortunately I didn't do a nandroid backup, as my phone came with XXALIH (without the multiscreen), so I figured I'd updated to LJ1 first.
Does anyone have any suggestions of what I can do?
Is there a full wipe ROM, or a way to reflash the bootloader and ROM?
It's 3am now, so I need to go to sleep, but this is annoying the hell out of me.
Thanks,
Rich

Carrier please?

True Move H in Thailand.
I don't think it's a carrier issue, as I can put the SIM into my Note 1 and get H or H+ data connection straight away.
Also, I compared the APN settings and I have the exact same settings in the Note 2 and Note 1.
Mobile data was working on the Note 2 when I first got it.
Thanks,

Turn mobile data on in settings/data usage.

I doubt that his data is turned off in the settings is the problem since he already stated that he tried resetting to factory settings.
I'd suggest simply using odin to reflash J1 onto the phone and start from scratch again. This is why the devs always remind people to do a nandroid backup. In case of situations like this.

Thanks. Yes, Mobile data is ticked. I tried toggling that early on in case it just wasn't connecting properly or something.
I've tried flashing the stock J1 a few ties, but no joy.
It doesn't seem to do a full install, as the circle battery mod I installed previously is still there after flashing stock J1...
I'm downloading a stock XXALIE for Thailand at the moment and will try that.
It's still got 30 mins to go, and I have to leave for work soon! So, I might have to spend the day relying on wifi when I can get it
I'm wondering if the change in boot loader has anything to do with it. (Originally had "N7100" on the boot screen and now I don't, just "Galaxy Note II")

maybe APN settings are wrong? I'm from sri lanka, and I had to add an apn for mobile data to work.

OK, I finally fixed it. Here is what I did (in case anyone else has a similar problem)
Flashed stock LJ1 via odin
Downloaded Galaxy S/S2/S3 CSC
Reset my CSC to THL
Now when it restarted it picked up mobile data signal without me doing anything to the mobile network settings.
I reflashed Omega 3 and lost mobile data again. I tried the Galaxy CSC app, but it says there is only 1 CSC.
So, I went back to stock Thai LJ1.
This time I got an OTA update straight away. After that installed I noticed the boot screen had changed back to showing GT-N7100 again.
ROM is now XXALJ3 and the modem is DXALJ1
Flashed CWM and reinstalled most of my apps from Titanium Backup.
Everything is still OK.
So, it looks like I can't use Omega ROM because it changes the CSC and I can't change it back to THL.
Is there any way to install the CSC separately after flashing Omega?

Mobile Network Not Available

Hey guys,
This may be a silly question, but I can't seem to find a solution.
I just flashed PAC-ROM 4.3 using CWM, and everything seems to be working great.
Than I realized I didn't have a mobile network signal, so I tried placing a call and it said "No mobile network detected".
How can I enable mobile network, cause it's not even in the settings no more?

I have the exact same problem, anyone with any kind of possible solution? Here's what I tried already:
1. Removed both battery/SIM for a minute or more then rebooted. (Also made sure that 2G was off)
2. Called a Koodo tech guy who updated the SIM.
3. Went in store to try and put my SIM in a different phone, SIM worked fine.
4. Lady tried installing a different SIM card (her own), still same problem. Tried a brand new one, still not working.
5. Backed up my pictures and factory reset the phone. Same problem.
6. Took SIM out, and the phone does recognize there is not a SIM card and now the phone gives me the NO SIM CARD message at unlock screen.
7. Updated to 4.3 - Nothing changes.
8. Browsed the internet for hours then cried myself to sleep, hoping someone would help me out eventually.

I had the same problem with revolt ROM. I flashed baseband and wiped all data but nothing changed...
I flash a factory image and it worked

I recently had CyanogenMod 11 installed on my phone and I noticed phone calls, messages, and WiFi worked but when I turned my Mobile Data on, It did not work even though it showed it was on. If your issue has not been resolved, I suggest you check this out - http://forum.xda-developers.com/showthread.php?t=2540998.

who is the wireless provider?

It's PlatinumTel (PTEL), which is a t-mobile mvno. I should note that i have the bootloader and the modem matched, have tried factory resets, and even downgraded to previous version (before updating bootloader to latest so i don't brick). Ptel tells me i need to update my APN, which basically was their standard msg... no help there. Thanks.

Hi, so... there are bunch of links and downloads on that page... i do have the latest bootloader and modem... can you tell me what you think i should [try to] update to make the mobile data work? BTW, at least on my phone, the mobile data icon doesn't even show. Not even 3G or whatever... thanks for your help.

RESOLVED!
Ugh. So after countless flashes, resets and wipes, turns out that PTEL needed to do a Data RESET on their end. So much misery for such a simple solution that they could have given me. If you're a PlatinumTel user, and this may apply to many other providers, please try telling them to reset their data service for you before trying anything else. Hopefully you won't go through the misery and time wasted that i have gone through.:cyclops:

All of them are stock but I personally chose upndwn4par - Full - Features : Odexed, Rooted, Knox Removed because I really didn't know what the other ones did. (PLEASE NOTE : Neither the developer or I are responsible if you brick, or mess up your phone! This also deletes everything on your phone so do backup if you want to save your important files.) When it finished downloading, I put the file on my phone's internal storage (SD card works too) then went into recovery mode using TWRP and installed the rom onto my phone, then while I was still on TWRP, I deleted the cache and data, it then reboot and then I had to set up my phone as if I had just bought it.

THIS NEEDS TO BE PROCLAIMED!
PTEL locked us out of voice once before, which also required a reset. That was also with a phone change so maybe a security measure? Never thought about it happening with data.
So many hours wasted.
On calling, the PTEL CSR first reset the data, then helped with a new APN. Note that even with the correct settings in an existing APN and the data connection freshly reset, the phone (SGN3) refused to connect, even after a reset. Added APNs had to be deleted, then a new one created, which then connected immediately. (Pissed and happy at once.)
Thanks, @geesedude, for this info; wished I'd found it sooner. (Have to stop assuming that if it doesn't work, must be something I'VE done.)

Glad that the information helped you. Yeah, i mean... since we mess around with our phones, we always first assume it's something we did, which really can't be blamed for thinking that way. Like you, i searched the web for a solution and it was out of desperation that i called ptel, and the CSR happened to suggest it (they were out of ideas, too), and it happened to be the solution. Not sure why they have to do this in the first place, but i am guessing that there are stricter guidelines from TMobile for the MVNOs, and they have to do some things manually. At least now i know to contact them first before spending hours searching for something that may not exist!

8.0 update made mobile data not work

I have the Honor 7x, and recently update to the 8.0 Oreo android update. Immediately after the installed the update in the morning, I noticed that my mobile data was no longer working correctly.
Wifi can connect, I can make phone calls, send text, literally everything else about the phone works perfectly.
A day later I got another update 8.0.0.332, however I am still unable to access my mobile data.
I use At t for my phone service, and do not have any damage to the phone (havent dropped the phone, water damage, etc).
My friend has the exact same phone, with the exact same phone service, and got his update the same day without having any issues.
Thing I have tried in attempt to fix the problem already based on google searches:
I have tried turning my phone into airplane mode, waiting, turning off airplane mode (also with trying a hard reset on the phone).
I have switched my simcard to slot 2.
I have put my simcard in another phone, and verified that the sim card is still working properly (the other phone was able to access data just perfectly).
I have tried turning off 4G data, and putting it back on.
I have tried resetting the APN back to default.
I have tried manually typing in my APN.
I have also tried network setting reset.
And finally, I have tried a factory data reset.
Running out of ideas of what else to try, hoping you guys have some ideas to help me out with this problem
Much thanks.

Flash a ROM and see if that does anything, if you want. Another thing to do is to do what the post below mind says, thanks.
Or join the Telegram Honor 7x group chat lol

Only one single step to do is
Go to Settings
Back up and reset

Pixel 2 XL cellular data issue with any custom ROM

Recently i have entered some state in which mobile data is busted on my phone. I have tested multiple android pie roms to find the same thing in each. When i flash the latest stock android (PQ1A.181205.002), mobile data is fine. In this broken state i can see the signal bars with a little 'R' by them (notification on lost mobile data connection Data roaming is turned off. tap to turn on). Every time i navigate into Settings> Network & internet > Mobile Network > Advanced > Carrier Settings. The screen will flash and take me back to Mobile Network, this happens with every custom rom tested. The app SprintDM tries to set up the phone 5 times and then fails. Phone codes seem to have no effect. the code 4636 will allow me to view current info in which it says mobile data disconnected. It doesn't appear to matter if i connect to wifi and allow the basic stock apps to update first. Reboots do not help. I even tried flashing the modem and radio for PQ1A.181105.017.A1 and OPM4.171019.021.R1. I can also say the phone app shows a message "This device is not supported and phone calls may not work correctly". Phone calls work fine. Previously i was running LiquidRemix (10.0.2) just fine, everything working. Randomly mobile data died so i tried a update to LiquidRemix (10.0.3) and still busted. Tested multiple other PIE roms to find the same. And again if i flash any stock firmware mobile data is fine. Anyone else see this or have an idea of how to fix this for custom roms?

I rooted my pixel2xl yesterday and installed Havoc OS.
Today I was out with my family and was trying to navigate via Google maps and it continuously displayed error "try again"
Status bar was showing lte connection then I tried opening chrome and was unable to use mobile data even if it being on and active.
I am planning to move to Stock again tomorrow

vipulkarkar, did you find out any other additional info on this? I went back to stock and everything is fine but would very much rather be running a custom rom.

Just seeing this post, fortunately, I've not run into this issue on stock or custom roms ... What I do run into, on stock or custom roms, is when I leave my house, with a T-Mobile CellSpot, I tend to switch to 3G or H+ in an LTE area. I sometimes have to cycle airport mode a couple times to get LTE back.. So odd and annoying!

Is there something we Sprint users could do to help the devs include Sprint connectivity in their roms? Like provide a nandroid backup of our device or ?
