MI - A2 No mobile data on any custom rom - Xiaomi Mi A2 / 6X Questions & Answers

I can't seem to get mobile data to work on any custom rom. If I revert back to stock rom then mobile data works.
Calling and texting works both custom and stock rom.
I've checked APN settings and they appear to be the same as on stock. I've tried a factory reset after flashing rom, reseating sim card, resetting apn settings, turning on 'always on mobile data' in developer settings, turning on airplane mode then rebotting phone, changed preferred network, checked sim card number for data.
Any ideas as to why mobile data would only work when on stock rom?

[Q] Data Network Mode/ Mobile Data not switching on

After upgrading to the LPY. My phone seems to be plagued with the problem of Mobile data not turning ON. It works sometimes and then after a while the 'E' icon in the status bar disappears and the data doesn't turn on no matter what.
I restarted the phone dozens of times. Removed the battery, removed the SIM. I even hit *#9900# and disabled the fast dormancy. No luck whatsover.
Could someone please help me out here??
I had to delete existing APN's and
Settings - More - Mobile Networks - Acces Point Names
press Menu now - choose Reset to default
For me it worked...
BTW do not forget then to select the one that is meant for internet (not wap, mms)
akshay, i had the same problem. just do a factory reset from your phone. be sure to backup your data via kies first if you want to save your data.
Thanks for the quick response. I deleted the APNs restored to default. Still no luck.
I don't want to factory reset cuz its way too much work to install everything again!
I would strongly suggest not doing a factory reset under lpy.
Another option that may help which I have done a few times successfully is to go to manage applications, find the dialer app and delete cache and data. This should reset your data connections and will prompt for the connection you need before reapplying.
Hope it helps.

I have a similar issue.. but only when I use a Stock Rom..
When I use a CyanogenMod based rom I connect normally.
Any suggestion if there's an option, in build.prop maybe, so I can fix this in a stock rom?
hi, you use a rom from XDA? is it happen after flashing a new rom, first boot, no mobile internet? -> how about some informations about runnign system etc. pp. was it working before with same rom? and so on....
if no internet after first boot: turn on wifi, go Settings/Xperia/Internet Settings , and try download the settings with wifi. how that?
second thought: your provider's fault?
Xperia V is not officially supported by my carrier, but I can use mobile data on cyanogenmod.
I tried to add APN for my carrier, but they don't appear, using APN Manager I could see and try to apply them, only to get an error.
I was willing to go back to stock rom 'cause I wanted to use sony's camera.. but mobile data is essential.. guess I'll to stick with cyanogenmod..
i have added my provider (three uk) network apn manually and it worked.. yesterday.. Now still I cant connect. No reaction at all. I've downloaded settings via wifi and didnt help. Im running official rom 9.1.A.1.141. It is not a provider fault - I used o2 before and it was the same problem. Sometimes restart helps. but not now,
edit. now restart helped.. i dont get it.. This is very enoying
Anyone have any ideia how to fix this issue?
In CM all APN are shown correctly, in any stock based rom I can't add any entries, or it's not shown.

[Q] No mobile data after installing custom ROM

Hi All - I tried flashing 2 custom ROM's (Monnlight and Mokee), both install just fine but i am unable to get mobile data on either of the ROM's. Everything works fine on Wifi. I can even make calls fine. My IMEI number is correct, hence not sure why i cannot get the mobile datat to work.
Tried manually entering the APN details, still no luck.
Hoping somebody has a fix.
Have you tried this:
dial *#*#4636#*#*
select WCDMA-preferred or CDMA auto-prl

Thanks Gary, I tried your code and selected various options nine work. I can still see the Exclamation mark and no mobile data. However on the diagnostic page it says "Connected" and network type "HSPA". I have tried multiple settings rebooting, still no luck.
The funny thing is if i switch back to my phone OS which MIUI v6 evrything works fine. I even checked the baseband number its teh same in the working ROM and the non working ROM.
I am really confused what's happening.
It seemed like a ROM issue I installed a non Cyanogenmod based ROM and it worked just fine

No Data On Cyanogen or RR

After unlocking and rooting my stock system, it still worked fine, but I wanted more features so I went to a custom rom.
Neither CM12.1 or RR had mobile data for Verizon.
When I flashed by TWRP backup of /system, I had data again.
According to 6Binford, my APN settings are correct.
Thanks!
If you upgraded from something other than the most recent -44 build, I think you need to update the radio. You can find that in the official CM thread for the Turbo.
I've tried flashing radio files but still no data.
I've also noticed this notification every now and then, even though I am in an area where data works perfectly fine on stock ROM, and even though before this pops up I still had no data:
Data roaming

You've lost data connectivity because you left your home network with data roaming turned off.

No mobile data on custom roms

Hi.
I can't get mobile data to work on custom roms.
I clean flashed Havoc, pixelexpirience and ZenX on top of xiaomi.eu. On all of them same problem, no mobile data. Phone can see my carrier name, I can call and text. Under the quick tile to turn on/off data I can see 4G icon. I'm currently on ZenX.
I tried reflashing rom, flashing xiaomi.eu and custom again (it's all fine on MIUI), wiping ALL data, restoring defoult APN, adding my operator APN manually.
Nothing helped. Am I missing something? Is there some zip to fix it? Tried looking for solution but no success.
I'm desperately looking for any ideas and fixes.
What Network operator do you use?
