No mobile data Connection with correct APN

Hello,
I am using my OnePlus One (64GiB) several days already but today i expierenced a total no data connection. It connects to WiFi and uses the Internet with no problems but if it comes to the mobile data connection it can't connect to the Internet while I have full network shown on the upper right corner. I can call and send SMS with no Problems. This Problem appeared just today and i called my service provider and they say that there is no problem with there network availability and I should check my APN settings which I checked and they are correct. Then the customer consultant said it could be my phone.
I inserted a SIM card from another service provider but it also does not connect to the mobile Internet connection.
So it seems to be that there is some faulty settings on my phone or even an defect. How can I fix that?
Thanks in Advance.

Ok. So your data connection was working fine with that same build previously? Nothing changed on your phone, it just stopped working?

That's strange! It seems like a very random glitch then, which often seem to fix themselves as randomly as they occur.
Have you tried rebooting your device, turning off/on data? Also, in Settings>Mobile Network Settings, is your preferred network type set to LTE, or the highest that's there?

Ok, and the "Data Enabled" checkbox in Mobile Network Settings is checked? And you are positive APN is all correct?
If yes and yes, then I'm not sure what could be the problem, considering how it WAS functioning previously. I would just suggest to keep rebooting and fiddling with the Network settings, such as turning off/on data, verifying APN settings, checking Network Operator, making sure SIM is properly inserted, etc.
I wish I knew exactly what was wrong, but I'm not sure.

A factory reset was my last option. Thank you this did fix it.
Did you resolved? I've same problem. Factory reset didn't work for me!
Hi,
I have the same problem. I only had the phone for three weeks now and two days ago internet stopped working in the middle of browsing/watching you tube video. Did not start since even though I've tried several methods (except factory reset, as I want to leave that one as last resort.
Is there any other way than factory reset to fix it ?
Do you all have franco kernel installed?

I lost the internet connect when I installed CM12 Nightly -> thought it was a bug in the ROM and sorta lived with it.
But when I reverted to 11-S I realized that the internet connection didn't work on that rom either. I've tried everything factory reset - Soft/Hard - reset -> flash other rom's on it. EVERYTHING!!! -> I also tried a couple of different SIM-cards none of them worked, I tried to contact my ISP, they couldn't help me, they said I had all the right settings so it's most likely something with my phone...
I've got no idea on how I can fix it. and would love if anyone could help me sort this problem out -> I don't have any important data on the phone so we can reset it as much as needed...

I did ask One Plus about it, they send me this zip (re-uploaded) http : // www . mediafire . com / download / rmuaie7f8ch5dji / ONEPLUS % 2BONE - StockRecovery - Windows . zip
(can't post links yet) which I then ran to fix the problem. just be aware of that it locks your bootloader again, if you don't want it to lock your bootloader edit the .bat files and delete the line which says "fastboot oem lock" and you should be good to go (worked anyways for me).
Thanks a ton this really was Helpful.. I guess OnePlus One has a glitch 11.1 and now also with 12.1 CM.. Will try Factory Restore and will update.. Same thing happen with my Frnd in India.. who switch between SP's. He had to restore to fix the internet issue.
I have had the same problem on one of my oneplus 2's. One phone works fine. The other phone was working but is not connecting to Internet using data connection. I have checked the settings and they are exactly the same as the other phone which is working fine.

[Q] No service? SIM card stops working

So today, my phone randomly stops giving me any service. No bars, nothing. It doesn't say that there's no SIM card, but there's a message saying that I should restart my phone because a SIM card was added. Is there any way to fix this?
There may be ways to fix it but it depends on what the problem is so you must troubleshoot it first.
The obvious first steps are to try the sim in another phone and try another sim in your phone.

Tried. My sim works fine in other phones. Just my Nexus
all then its either software or hardware. If you're on stock ROM, factory reset. Still not fixed? Needs repairing

[Android 5.1] no service

My phone has suddenly stopped having any service whatsoever, I have tried everything, factory reset, format data, but have still been unable to get anything. I tried playing around with the radio settings and the APN but that hasn't worked either. If anyone has some ideas, they would be welcome.
Did you try putting the sim card into another phone?

Try to flash Android 5.01 radio. My radio/service was very bad in 5.1.

Pay the bill
Does the SIM status screen show your phone number and IMEI? I had a Galaxy Nexus once that quit working, and those were blank (or maybe it said unknown) in the status screen. I figure possibly the EFS partition developed a fault or got corrupted.
I flashed the 5.0.1 radio and was able to get service again and can now text but I'm still unable to call anyone.Whenever i try to dial the number it simply goes silent, loses service and ends the call. I am also still unable to receive calls as well,all calls people attempt seem to cause me to lose service and only get a voice mail afterwards.
I haven't checked the sim status screen yet and I am unsure as to how.

Maybe try pulling the SIM and re-inserting it? Couldn't hurt.

If it was me, I'd try flashing the radio from Factory 5.0.1 (LRX22C)
It is baseband M8974A-2.0.50.2.22
Extract the radio from the .tgz
Here
You can always flash back if their is no improvement
Thanks for the suggestion but I have already done so and I have observed no improvement. am beginning t suspect that it may be an issue with the EFS but I'm not sure what steps to take to verify this.

After flashing 5.01 radio, did you try to wipe cache and dalvik cache? Maybe the phone process still has bad cache (if possible). Just a try! I hope it works. Otherwise there is some big problem
Thanks for the advice. I am considering filing an RMA with google although I'm unsure if I'll be covered since I live in Canada

If you suspect EFS corruption, try restoring any TWRP backup you made prior to the problem.
The EFS partition will be present in the backup, unless you unchecked if you checked that partition in TWRP Backup.

Efs is not backed up by default. You have to choose it.
Sent from my Nexus 9 using XDA Free mobile app
I have a similar issue. After I updated to 5.1 my mobile data doesn't work. I tried everything listed before in this thread with no result. I don't know what is happening. The first one I updated using 5.1 factory image. Reverted to 5.0 Factory image and it worked again. So, I update by OTA to 5.01 and then to 5.1, same results. This drives me crazy! I want 5.1 on my Nexus
BTW I have D821 model. Any suggestion?

Thanks for correcting me:good:
There is another topic on this matter (i.e. common problem): http://forum.xda-developers.com/google-nexus-5/help/sim-card-recognized-upgrade-to-nexus-5-t3054267
For me it helped, ejecting and reinserting the SIM card. But I had also flashed other ROMS and cleaned the SMS/call/contacts database. So not sure why it worked.
I also notice that my System UI frequently stops. Does anyone have a stock System UI for me? Many thanks!
I am having similar issue and SIM status shows Radio off, how do I turn on?
Thanks.

No Sim error on nexus 5

Hi guys its been a month since I am facing this no Sim error. After N number of restart it detects Sim and issue comes back again after 2 days or if i restart my phone. Then again I have to restart for number of times to get signal back again hence i dont think it is a hardware issue. I don't know wether upgrading to marshmallow has done the harm or a month back i completely drained out my battery, that has done the harm? I tried updating/changing the rom, bootloader Version, baseband Version but no luck.? I love my nexus 5 and 8 don't want to dump it. Please help me find solution.
ROM CHROMA 5th April build date.
Android 6.0.1
Baseband M8974A 2.0.50.2.29
Please help me find the solution for this.
Flash factory images via fastboot to revert back to stock. That should fix the sim error reading.

Lock the bootloader? Or just flash (I don't want to loose photos and music on my phone)

is it necessary to flash userdata.img?
Flashing userdata.img is not necessary if the phone will boot.
I recommend flashing TWRP, booting into TWRP, and copy your data off the phone to a computer.

Is it possible that the sim reader has been physically damaged? Was the phone use with any type of nano to micro sim adapter?

I don't think it's a hardware issue, because say after 10-12 restarts it detects sim
Maybe the SIM card is defective? It could still be an intermittent hardware issue.

The same Sim card works fine on other devices and tried different Sims too. Still no luck. Can this be a Marshmallow issue? I have read people having this issue after updating it to 6.0.0
I have worked on 7 to 8 nexus 5 phones, all with mm and none of them experienced this sim issue. 7 to 8 phones is not a large sample so I can't really make any conclusive statement.

Will reverting back to kitkat do any good?
Btw after 10 restart i have got back the radio. But this is not the solution but a temp fix. I hope it does not lose it again.
You could try flashing a completely stock kk rom but I am not sure this will fix the issue. You could always try since flashing is quick, setting everything again is a pain.

That is the main issue. Wiping completely and setting up device is really boring. Hence i wanted to know if anybody has tried and solved this issue. Anyways have to try for the love of my nexus ?
I have the same issue (not detecting simcard after booting - no signal after reinserting the card) and a complete reflash of the image has not resolved the issue. Neither has a factory reset etc.
Still stuck with a non phoning phone basically...

So your phone also detected Sim after many restarts or it never does,?

It never does after restarts, but it does detect it immediatly after I remove the card/tray and put it back in. I have to do this each time the phone restarts.

Does it get network? Mine also detects Sim but does to connect to network and says no service.
Nope no network at all. No service is all I get as well.
Searching for networks also fails. Via the diagnostics menu I see that the radio is turned off, but I cannot activate it.
Tonight I'm going to take out the battery and see if that resets the hardware... If it works I will let you know.

Reset SIM Settings! SIM dead

Hello,
Yesterday I called my network operator since I was the only one in the office (compared to others with the same network operator) unable to receive calls.
The support made me receive a Network Configuration SMS, I applied it and immediatly the SIM started to turn on and off (see link):
https://imgur.com/a/uLAhcDU
As of now, my SIM works on other phones, other SIM (from same and different network operator) works on my phone. Looks like a configuration issue directly connected to my SIM/IMEI.
Tried to reset what I've been able to reset, and to reflash ROM. The only option left is to factory reset, but I'd not like to.
Is there a way to reset the SIM configuration? I am rooted if needed.
Thank you!

Just look on the internet for the APN settings of your provider and fill them in manualy, pritty sure there was something wrong with the configuration sms you got, was probably for oreo, not for pie

Was afraid of that.... Strange that reinstalling the rom did not work, would expect a reset to the older APN settingswith the new install. You can try to delete the system partition first before installing the rom again, don't know if that will work, but hope you will get the old APN settings again. With a factory reset it should work ofcourse but can inmaging thats not your first option....

Deleting system partition didn't work. I'm sure it was some config in my data.. Maybe it was just a file to delete/modify.. Anyway I've ended up doing a factory reset.
Thank you for your help!
