is the apn information on the sim card? I am on US AT&T and every time i flash a rom. does not matter what rom it is custom or stock it provisions the wrong apn. it provisions for US Tmobile 310 280. instead of 310 410 for US AT&T. calyxos would let me select the correct apn but i still do not have data.
i have been to 4 AT&T stores and all they want to do is sell a phone. 611 was worthless and they wanted to sell me a phone..
is it a sim card problem? does anyone have an idea of who i need to talk to so i can get this apn provisioned to the correct carrier? or what i can do to fix this problem?
If you are setting up a new device or putting your SIM card into a device for the first time, your network operator should send you their APN details in a configuration message. Your APN details will be different depending on your network operator.
I think it is a sim problem because you are saying that is a problem data whit the correct apn
Sometimes is a rom problem so try installing the stock one.
Ex: Samsung custom rom doesn't support 4G, only 3G/2G and LTE.
i tried the stock pixel 5a rom 11 , 12 and beta 13. lineageos, pixel experience. all of them seem to provision the wrong apn. i can't edit, change the apn or add a new apn. to see if any of the other apns work. or at least 4g or lte mode

This may be an old question, but I've been unable to find an answer...
I have an off-contract verizon Droid 3. So I flashe the radio ROM with the Chinese 883 variant. I took it to the UK and put a "3" SIM into it. I got voice + txt, but I didn't get data.
(I didn't have a PC in the UK so I couldn't do more testing... had to wait until I got home)
OK, I come back to the US and I do some testing...
I rebuild from scratch with 5.7.906. I force the machine into GSM mode. Then I use "Network System Information" (NSI). I see my SIM card; my UK phone number, MMC, MNC. But, of course, it doesn't work in the US becuase the phone won't talk to US GSM networks with Verizon firmware.
I change the radio to the Chinese radio.img, as per http://forum.xda-developers.com/showthread.php?t=1406812 - I also replace build.prop, /system/lib/libmoto_ril.so and /system/etc/ppp/peers/pppd-ril.options
Now I reboot and I can see the GSM network (T-Mobile, in this case), but NSI doesn't get to see SIM contents; no phone number, no MNC, no MMC. And so I'm back to phone+txt but no data; the APN isn't picked up.
Do I need to do something else to get data working?
(Probably if I leave it with the Verizon radio ROM then next time I go to England I'll get data, but it means I don't get the SIM working while in the US).

Grab a T-Mobile prepaid SIM so you can test further. You shouldn't have to replace any files except the radio and build.prop for the 883 Chinese radio from the Verizon XT862 radio/build.prop.

OK, I rebuilt back to Verizon factory just so I have a clean slate.
I don't have a T-Mobile SIM but I do have an (expired, deactived) UK Virgin Mobile SIM.
I put that in the phone with the Verizon Radio ROM and, as expected, it won't connect to AT&T. NSI will show me the MNC, MCC, phone number and othe SIM details.
I switch to Chinese ROM and build.prop... and I can still see the details! This is something new...
OK, with that level of success I switch back to the 3 SIM card. And... no data.
So:
Verizon Radio and build: 3 SIM visible in NSI but won't connect. Virgin SIM visible in NSI but won't connect
Chinese Radio and build: 3 SIM _not_ visible in NSI. Connects for voice+txt, no data. Virgin SIM visible but won't connect ('cos expired)
Hmm, looks like some interaction between the radio and the SIM. Odd!
Sorry I meant get a T-Mobile SIM so you can test the 883 radio.
What testing are you proposing? Other than "data works with a T-Mobile SIM" of course
Since the MNC and MMC aren't visible with the Chinese ROM and the 3 SIM, no APN is selected and so no data... with the Virgin SIM the MNC and MMC are visible and I can see APNs in the APN settings screen.
all i ever did was 1. get unlock code , 2.flash 883 radio , 3. change build,prop.
have to root first of course.
never ran into an issue except once when i accidentally erased some files in the system folder.
I have never understood why install xt883 radio when xt862 works great with gsm networks (all G/E/3G/H connection modes with data). Is there any reason for doing that?

The xt862 radio is unlocked for gsm networks outside the US, but will not allow US GSM SIMs from T-Mobile and AT&T to work.

It's not the SIM, it's the network. A UK "3" SIM won't join T-Mobile or AT&T with the Verizon radio ROM, but it will with the alternate ROM.
SOLUTION
Hi and morning to you. I work for your carrier (TECH SUPPORT) so i think i know what the issue is. you can call them and verify this i'm sure they will agree but dont mention my name
3 sim card only works on 3g network and when you put the phone in a 2g phone it dosent. i know the droid 3 is 3g but like you there are 80 % d3 owners having same issue of no 3g data. when you root and install a rom the data capability goes away. try this .......
set up a new apn WITH ► NAME : 3, ► APN : THREE.CO.UK and go to last option ► apn type and type the word "default" then save and reboot. dont forget to activate mobile data. i think it will at least give you 2g kind of internet. i have droid 3 and i took it when i was in the u.s and now in india
lemme know it it works. forgot to mention....there is patch to get 3g data working (google) it.

No this doesn't work because the MNC and MCC aren't visible and so the phone won't select the APN.
Sad it dosent work. Why dont you upgrade phone to Droid 3 stock (download unbrick Droid .bat from Droid 3 developement unbrick/root 1st post and then start from scratch like rooting , safestrap stc ) in case if u flash n if there is no signal then activate roaming. I have done d same.

That's exactly what I did; I reflashed to 5.7.906 using moto-fastboot. With the VZW radio ROM I can see the SIM MNC MCC but (of course) it won't talk GSM in the US. With the Chinese radio ROM it'll talk to the network but without data 'cos it doesn't see the MNC MCC.
The whole question is moot now 'cos I've now got an S4 and cut the SIM to size; that works just fine

I've ported xt861 (2.3.6) rom to xt862 (called it cROM) to use it in Europe/Poland, but have same problem with data transfer. The solution was:
1. download full apns-conf.xml file with most of world networks apns (about 160kb)
2. copy the file to /system/etc/apns-conf_0.xml
3. create two links
ln -s /system/etc/apns-conf_0.xml /system/etc/apns-conf_.xml
ln -s /system/etc/apns-conf_0.xml /system/etc/apns-conf.xml
4. reboot
Try this (from terminal):
su
rm -R /data/data/com.android.providers.telephony/databases

I just got my wife a Nexus 6 from Craigslist. I foolishly didn't 100% test the phone and I think I got a lemon or something.
Her phone has never connected to LTE. I've tried manually changing APNs, swapping SIM cards with my phone to see if the card is bad, checking the phone settings by dialing *#*#4636#*#*, etc... And everything is identical to my Nexus 6 with no luck. I went to a T-Mobile store just now and they couldn't figure anything out.
Two questions:
1. Is there anything else I can do to get LTE activated?
2. Can an LTE radio be damaged or disabled somehow?
I'm at my wit's end here... I'm hoping y'all can help me get it fixed.
Thanks!
1st is the phone running stock or a custom rom? .second try to reset your apn setting to default and using the setting that the phone provides in apn
It is stock, no customization or rooting.
I'll try the default when my wife gets back from the store and report back.
Reset APN to default settings, no luck.
The previous owner was on a smaller carrier, like a Metro PCS or something similar... Can't remember, but I don't know if their settings are different than T-Mobile's.
Yes their settings are diff... metro is fast.metropcs.com for apn inside and tmobile is fast.t-mobile.com. You can try clicking the apn make sure its fast.t-mobile.com and check the ipv and set to ipv6 and ipv4 for roaming. Then at the very bottom under MVNO select None. Then restart phone. If your still not pulling up data you may want to push a radio image to the device possibly and maybe the radio firmware is screwed up since your not original owner of the device.
All the APN settings are correct and identical to my working Nexus 6.
Are there tutorials on how to push a radio image and where to get said radio image?
https://www.androidpit.com/how-to-update-nexus-5-bootloader-and-radio - Nexus 5 instructions but they are the same just download nexus 6 files instead from here
https://dl.google.com/dl/android/aosp/shamu-mob30i-factory-21357b09.tgz - MOB30I Latest Marshmallow files...
When you follow that guide you could just flash-all command it and flash marshmallow stock in its entirety... it would flash latest bootloader and modem with it or you can extract the modem and bootloader files from the file and follow the guide. If you dont care whats on device you may want to just flash the whole thing and skip the extracting the modem and bootloader parts.
**Obviously since you'd be replacing the nexus 5 files with 6 files aka shamu instead of hammerhead change the names in the commands you type in fastboot. Just a reminder.
Thanks so much for the help!
I'll try this later and let you know if it works.

Enter into the bootloader and check the Product/Variant information within. For the US, it should read "shamu XT1103" followed by the memory size and a hexadecimal string. If it reads "shamu XT1100", you have the international model, which would explain the trouble you're having. Another possible explanation, especially if the model is "shamu XT1103", is that the device is blocked on T-Mobile.
To answer your questions:
1. If you have an international model, you may be able to activate the missing bands necessary to support LTE here in the US. Otherwise, flash the latest ROM from Google, as there are settings in the services menu you accessed which once selected cannot be changed unless a new ROM image is flashed.
2. LTE radios can both be damaged and disabled. The LTE could be disabled in the service menu, or the hardware is damaged.

I have same problem. I have XT1100 on T-Mobile, but I can only use 3G. How to see which LTE bands on this devices are activated?
If you have an XT1100 in the US you're missing bands 2, 4, 12 and 17. Of those, bands 2 and 4 are the most important as AT&T and T-Mobile both use those bands extensively. And unlike the US model, Verizon and Sprint won't work at all. Search the General forum, as there is a thread on how to add bands to the radio. Be warned however. When I attempted it on my Galaxy S4 I nearly bricked the device.
Also (and I know its basic) but check under settings ---> mobile ---> preferred network type and make sure it says LTE (just on the off chance it was switched somehow)
Hi there:
I had a rooted nexus 6 with Android 6.
I was playing with chmod and root and messed up some system permissions.
I have re-installed several Nexus 6 Google images 5.1 6.0 etc...
I have everything except cellular signal. It says no service and sometimes no sim card.
I have taken my sim and put it in another phone and it worked.
When I go to *#*#4636#*#*
It says GSM: emergency service only and GPRS service: disconnected.
I tried to change the network type to GSM only and others with no success.
Any help to further diagnose this would be appreciated..
Thanks

Very good point.
When I flashed 6.0.1
under cellular network settings , I only see Data raoming, Preferred network type and System select.
no APN settings
When I re-flashed 5.0.1 , I could see the apn settings, but when I go to it, it says something like that the user doesn't have permission to view the settings. I even tried to add a new settings and save it, but the message stayed there and I see no APN list at all..
I might have messed up the APN permissions with chmod, but I would think a system re-flash would have corrected it..
Thanks

Does your IMEI match the number on your SIM card tray?
I'm having trouble enabling VoLTE on the latest build (02/11) build of cyanogenmod for my Mi5 32GB. It wasn't working on the earlier builds as well. Sometimes after a clean flash , VoLTE works just fine and then after sometime it just won't work (No HD symbol after the sim name ) . I'm using a JIO sim and it would be really helpful if someone knows any workaround for this issue as I know many people are facing the same issue even after having the updated radio firmware after the 31/10 cm 13 nightly.
I tried different APN settings , but failed.
For reference , I'm using the following APN setting on miui8.
APN : jionet
APN type :default,supl.
It would be really helpful if someone knows any workaround for this problem , as I had to go back to miui ( which I don't like a bit ) because of this issue in cm which is otherwise a quite stable and clean rom.
Thanks in advance
it works fine for me always, im using jio in first slot and idea in other and in sim settings jio as default for data and and sms , for calls ask on call. in apn jionet,bearer lte,server www.google.com and even if it doesnt show hd calls works fine and connects.
Just delete all apns and add a new apn with:
Name: jionet
Apn: jionet
Rest all leave default...
It's a hit and miss thing... Works sometimes and doesnt, so best thing is to download the jio4gvoice app... When it's not in HD... Use the app to call... When it's HD... Directly call from phone...
there is no hit and miss case for me here in telangana region with same apn settings i mentioned above from cm 31 build onwards. i have called 30+ times with no disconnect.
No it's not working, I never get proper network on cm, I'm using Jio on 1st slot and airtel on the second slot, never get VoLTE though.
It used to work on the 12/11 build. But after updating to the latest build , it stopped working
Latest 18/11 cm 14.1 build also doesn't help. I tried creating Access point settings manually , but still with no luck. If anyone found a workaround for this, please share it here.
Works 100% for me. No issues. Just set the correct apn and make sure you enable it. Then restart the device.
