[Q] MIUI v.3 Data Problem

Hi, Just installed this ROM using the recommended kernel (percy_g2's CM#2). I've search for a bug related to data connections but seems It's only me. SIM card recognizes my provider and I can make/receive calls and sms, but using the data plan it's impossible, showing it's disconnected. Checked and unchecked the roaming option and still doesn't work. What are my options?

Reset apn settings to default or manually enter them - your provider can send you the settings
Phone settings
click more or wireless and network settings
Mobile networks
access point names
press menu button on phone
reset to default
Check the apn settings are present & correct for your provider or enter them manually

Did it and didn't work. As far as I recall, in all other roms I have installed I never changed settings ain APNs, they were empty all the time. The phone automatically gets the connection to the carrier. It was all about enable or disable data.
I called my provider but they say the network itself should recognize you inmediatly.
I just flashed stock and it's working there but not in MIUI.

Iv always had my providers access point in my apn settings but may be different for others
The only other thing you can do is try a different stock rom firmware baseband
you can do this by flashing a different stock rom firmware via odin to what you are currently using
See dokys thread at top of dev section for a list of pre done flashable odin firmware or make your own with any latest firmware from sammobile.com using the splitter tool

Could flashing a different Percy kernel may work?

3G not working(APN issue)

I changed my usual SIM(vodafone italy) to another SIM for work(chess mobile norway).
All worked fine with it, 3g wifi, as usual.
Then when i finished using the norwegian SIM i went back to the old one (italian vodafone), and no 3g working.
the APN menu is empty.
I try to press + to ADD and it crashes( settings crash).
I press bottom left button then press return to default APN , and after 10sec i can see the Internet,Wap,MMS entries but after some seconds they all dishappear.
In those seconds i can see the h+ icon blinking for 1 second and then dishappears leaving the APN menu empty as described above.
After this first attempt if i press again to get APD defaults nothing happens.
Then I try again to use the norwegian SIM on my S4 and it works well.
I don't have a clue what's going on.
Any suggestions?
:crying:
Cheers
P.s: the phone is rooted, knox removed ,android 4.4.2,

already tried. Nothing changes.
I have just got another phone to test the sim, and 3g is working.
So if I was able to add an APN maybe i would solve the problem.
But the APN settings crashes all the time.
No chance to make any new connection.

1. Make a backup of all your data.
2. Make a factory reset (pic attached)
3. Try again.

Thanks for help very much, but it didn't help
Should I do factory reset?

I did the HARD reset and it worked. So 4 someone having the same problem that is a drastic but working solution.
Seems that using a SIM from another cowntry made a lot of mess in the S4.
Thanks 4 Help

Samsung Note 3 doesn't want to recognize/register my SIM

I'm not a 100% sure how this problem occurred, I believe it was after flashing an S5 custom rom called: "RC Elite S5 Port V16" To my Samsung Galaxy Note 3 (N900W8). From what I was reading it was a ROM that "converts" your note 3 to a note 4 or s5, while still having all the Note 3 features. Another possible cause is trying to use RegionLock Away.apk by Chainfire to essentially(unlock) the phone. I feel like this is the main cause though as this affects the modem on the phone. This isn't the SIM as I tried it in another phone and works fine with calls and texts.
My phone doesn't want to register its mobile network anymore. When I try to make a call or text it says:
"Not Registered on network"
I was reading online for about 2-3days now for possible solutions that can cure this. Such as:
1. Going into Mobile Networks settings and manually register [failed, details below]
2. Going into Mobile Networks settings, hold home button for 2seconds and then hold power button + home button for 15seconds [failed, details below]
3. Taking out battery while the phone is on and remove the SIM card, clean it and re-insert [failed]
4. Factory Reset [Failed]
5. Wipe Storage and re-flash stock ROM [Failed]
Options 1 & 2 do not work because when I try to access Mobile Network Settings I get this:
"Insert SIM card to access network services"
The SIM card is inside the phone though...
So what I did is found a mobile network options shortcut "program" from GooglePlay Store and installed it. It allows me to access the menu, which is great! Now, when I try to register the SIM card to my correct service provider (BELL CANADA)...it will make me wait for about 1-2minutes before I get "Unable to register, try later" error.
I tried the factory restore with a stock 4.4.2 ROM from Sammobile and the issue is still there.
Is there anything that anyone knows that can help me resolve this problem? I tried EVERYTHING i can possibly find on Google. I've seen posts of people suggesting to flash a modem.bin file with Odin but I don't know where to get those files, nor what to look for in terms of modem file "types".

Many thanks for your swift replies. I have it layed out in an album with thumbnails at the top. Hopefully it made it easier for you to look. I skipped past DEVICE ID as a whole as both IMEI and SERIAL #'s are 100% original and legitimate.

I tried region unlocking it with RegionLock Away by Chainfire. I would like to say afterwards this issue occurred but as far as im concerned, using a TELUS Mobility sim card activates the network pin unlock. So i'll be going with no, it's not unlocked.
I currently have a Bell LTE 4G SIM card installed on the phone. If you check the photos there it shows I have a full connection but unable to make calls nor access the mobile networks menu.... =/
I can provide pictures on the error messages if you'd like.

Edit: I'm performing a factory reset right now. I'll let you know if this fixes it. Thanks.

These errors are really getting the best of me. I can't use my phone anymore D:
And as mentioned in OP, I downloaded a shortcut from the GooglePlay store that allowed me to access the Mobile Networks options. When I try to register to bell i keep getting "Unable to connect, try later"
Thanks for your help.

Do one thing.
1. Turn off the phone. Take a out the simcard and battery for some min.
2. Add the battery only. Turn on the phone and factory reset your device (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything.)
3. Insert SIMCARD without turn off the phone.

They there! I tried to follow all the steps to the best of my ability but it seemed that didn't work. For 1, the note 3's sim card slot is blocked by the battery so i can't take it out without turning it off. In addition, after only inserting the battery and performing the factory reset, I decided to test it and the issue is STILL there even though a sim card isn't even inserted AFTER the factory reset. Same error messages as if nothing ever happened, even shows full bar reception even though nothing is in there. =/
This is the most unique problem I have ever encountered myself. I really don't know what to say...

Bumping.
After some more research I was wondering if you reflash the stock firmware back, does it effect the EFS partition at all? Cause if it doesn't I believe I installed a faulty EFS partition accidentally which results in the broken connection.
Any way I can get a backup of an EFS file that I can flash?
Thanks.

Bump. This issue is driving me nuts.
Thank you in advance.

Sim works in other phones, new sim doesnt work.

Issue still there.
Thanks in advance for the replies.

I had this same problem earlier (for a note 2) in the week where it just wont register any sim card.
In my case i think the problem was that i did a full format before flashing which probably deleted the EFS folder.
I tried so many options and eventually managed to resolve it by following the following instructions to restore the stock firmware.
Edit: Unfortunately i cant post URLs as i dont have enough posts

Hey there!
Thanks for your swift reply! I had already did the Samsung Recovery via Kies 3. Do you know if I reflash it that way that the EFS folder would get flashed as well? Because after doing those steps the issue is still there, after about 3 firmware recovery flashes. xD
I didn't even think about backing up the stupid EFS folder otherwise I would have. I was looking at this

Is this the same one? xD
Thanks again.

Hi everone.
I have been using my Mi A1 for bout 5 months and all was good.

Can anyone help please?
Thanks.

Thanks fort he reply.
If I factory reset it will (obviously) go back to out-of-the-box settings but will then take the latest AO updates and will result in the same issue :crying:

It's only a network setting reset (NOT factory reset) which would only wipe your network related presets like Wi-Fi, bluetooth, and mobile data.
Give it a try then feedback.

Thanks for the suggestion however, that has not resolved the issue.
Just to add, these USSD codes have only stopped working since the second last update July for Android One. Have checked with teh network operator and they have not retired the codes.

If you are using dual sim, you might have set the dial to another sim. Change that to "Ask first".
