I have been updating my 4G XOOM for many months with no issues to the Team EOS nightly builds Stingray 4G versions. The 4g data connection has never had issues until I installed EOS-Stingray-96 and newer. Basically, it seems as though the XOOM no longer detects the SIM card with 96 and newer. If I roll back to Eos-stingray-94 and older once again my sim card is detected and data connection working again.
I have confirmed this is also occurring with the Jelly Bean builds that is will not detect the SIM.
I have tried the usual, pull sim out, put back in, replaced SIM, reboot, power off, etc.
The Status shows the following on the builds that cause the SIM card to not detect.
Signal strength 0
Mobile network type unknown
Service state out of service
Mobile network state disconnected
Any help with this is greatly appreciated.
Well if you would search the thread you would know you would have to flash the new radio to maintain your mobile data....
EDIT: And here you go
Also be sure to update your recovery before flashing that

I have a very strange problem with my Thunderbolt that is connected to newer Gingerbread ROMs with Sense 3.0.
The thing happens is that the SIM card is not detected by the device in those ROMs (Gingeritis 3D Beta VII, Synergy and Liquid Gingersense 1.6. I have run them with the MR2, MR2.75 and the leaked MR3 radio and different combinations without any success. I have also updated the CWM to the modded 4.0.0.5 from 3.1.0.2 and completely wiped /system, /data and Dalvik cache between every flash.
When I flash an older Gingerbread like Gingeritis 1.2, the SIM card is detected again and contacts stored there show up. But immediately when a new Sense 3.0 ROM is flashed, it simply disappears which also removes the 4G connection of obvious reasons. The result of that is a complete loss of all data connection. It's possible to get 1X with the cover off (removal of the 4G antenna) but immediately when the cover is put back, all connection (including 1X and 3G) disappears.
All problems seems to be related to some kind of compatibility problem between the SIM card and the newer ROMs. My Thunderbolt is one of the first out there and it runs the first "Easy root" method that was released.
Beside this strange problem with the SIM card and the associated loss of data connection, it works perfect.
It would be interesting if there are any suggestions. I have double checked all MD5 checksums to be sure that all ROMs has been downloaded properly.
I am grateful for help with this issue. I would prefer to run the latest Sense 3.0 ROMs with working 4G.

My guess would be a bum SIM card. It really shouldn't act like that regardless of ROM or radio.
I decided, out of curiosity, to try with my T-Mobile SIM card to see what's happen. It can be read and show up in the phone book properly. So it seems like I have to order a new SIM card then.
It's a bit strange that the card fails this way because I've never experienced that with other SIM cards that I have used for years. But the inability to read it with specific ROM/radios indicates that there are some kind of compatibility issue. My SIM is one of the first they shipped with the Thunderbolt so perhaps it's a part of the bad batch.
I have now made some additional experiments including flashing the device without the SIM inserted. That removes all abilities to make calls, obviously.
When the SIM is reinserted, it found the network with a strong signal and calling works. I have now also noticed that saving contacts to the SIM works and the People app can show them properly. The only place where the problem shows up is under Wireless and Networks under the APN settings. When I enter that part, it says "no SIM found". Otherwise the card is obviously found by the device and calls are working. Data connection is not working though, it's only if I remove the battery cover that I can manage to get 1X working. So there seems to be something going on with the SIM in the 4G department.
My experimenting indicates that the SIM is working otherwise. When I tried other ROMs I have now noticed that the 4G is missing, it can't connect on 4G at all. The difference is that "SIM card not found" under APN settings is not shown.
Status for now with other words:
1. Phone calls works.
2. Saving and managing contacts to and on the SIM works.
3. APN settings presents the "no SIM card found" message. The APN itself shows up.
4. Data connection is not working with the battery cover on.
5. With the battery cover off, I receive 1X.
I have also tried to set it on CDMA (auto PRL) without any success when it comes to data connection with the battery cover on.
Hi guys.
Just trying to share my observation and explore if we can do anything.
I am using D6683 (I think it is support to be a HK based handset). Using Lollipop, it has been working perfectly but 16GB not enough hence MM function that allow SD card and Internal memory merge is appreciated.
Since Sony decide to ditch us using D6683, the only option is using D6633.
1. Try using MM .575, it has huge connection problem. The phone will just stay in GPRS mode even connected to a LTE network. Driving from one point to another point, will just cause it to data connection to hang. Putting it in airplane mode and anything else won't work. Only reboot works
2. Restore stock and upgrade to .291, first day testing seem to be ok. Got LTE connection. It did try to swing a bit but it has been maintaining well. This i started driving with Waze. Connection start to go haywire, but it will be still try to reconnect. Data are "maintained" to certain extend. Let the phone along for about 2 days, the next thing I realize, only GPRS left. The signal logo got no more H, H+ or LTE. Check the phone service menu and all info confirm the LTE is available. Again a reboot fix the problem.
3. Change the setting to only WCDMA + GPRS. The phone was "perfect". No data hang issue and etc
Need all the sifu help. Assuming if the phone is rooted, how is the phone determine the connection method? I presume that the phone will initialize the modem to dial the connection. Can anyone share anything that we can probably trigger a redial and probably eventually inject into the phone data connection sequence. Again using Lollipop, there is no issue.
Appreciate any comments/advice.

This is a Galaxy S5 on the Sprint Network with Lineage OS version from a few weeks ago.
Last week this was working fine and then since Sunday cell service stopped working completely. The only change I did was updating TWRP, I did not update LineageOS, but I can't imagine TWRP would have affected it. I ended up reverting back to the stock ROM thinking I would have to call Srpint customer service, but then it started working under the stock ROM. Reflashed TWRP and Lineage OS and no service. Tried older and newest versions of TWRP and Lineage OS but nothing works except stock ROM (yuck).
The cellular connection says "no service" with completely empty bars. About every 5 seconds it will flash like it is connected, with most bars and the little R for roaming, then immediately goes back to "no service". I've tried changing preferred networks and looked at settings but can't find anything to fix it.
Any ideas? It's almost like the network is rejecting it but I don't see why it would matter if it is a custom ROM.
EDIT: oh yeah and on start up it says "Activating cellular service... This may take up to 5 minutes" or and then after a while says "Couldn't Activate" and that it may be fixed by restarting the phone (which of course doesn't fix it). Also I'm not entirely sure if it is related to roaming or not.
EDIT2: I'm wondering/betting this has something to do with the ICCID number. I noticed with Lineage OS installed it says "DUMMY_NV_ICC_SERIAL" but with the stock ROM it is a long string of digits. Now maybe I can change the ICCID on Lineage OS? Or maybe Lineage OS isn't reading my sim card properly (from googling what ICCID is)?
I'm having similar issues trying to use this phone on FreedomPop. It looks like the cell services sometimes continually crashes/restarts - a reboot usually clears that up. I also get no LTE data (3G works fine). I have the correct APN AFAIK (https://support.freedompop.com/app/answers/detail/a_id/3322/~/apn-settings---lte-sim). Possibly related to the "DUMMY_NV_ICC_SERIAL" issue?
I've been experiencing this issue for a few weeks now. My LTE data is functional but I cannot send SMS while using 4G. The activation screen pops up when I restart my phone, and it will only activate under Sprint 3G service. I also have the same issue with the flashing service bars, every couple of seconds -- the only way I've found to remedy the lack of service is to turn roaming on and off -- after so many tries, the prompt to select my sim card pops up and it finally connects to the sprint network.
I dont know why this has worked for me but its been a struggle and a wicked pita for me. I use Tello as a provider which is a sprint mvno. This last time to get cell signal i had to flash a stock rom via odin doing a full factory wipe to the phone. I booted into the stock rom to make sure i had lte connectivity. Then booted to download, flashed twrp via odin. Booted into twrp. installed remastered remix 5.7? The next to latest ( marshmello version not neuget ) then booted into RR. Once there i switched it from global to LTE and added the tello apn. I can not connect but i have no idea why this worked. I would love it if someone could tell me why this worked and what i can do in the future to save myself some headaches, flashing factory rom every time i want to change a rom sucks.

So having a strange issue hoping someone can help me with.....
Woke up this morning phone was working, since my phone was charged I turned off "Battery Saver Mode" and after i did that I lost network connection. After checking that the network wasn't just down I began by flashing to stock flashing "3CRE2", thinking maybe something in the software no go.
Decided to apply the stock updates, I did this for awhile to no avail.
When I hit update 29 I think it is, the update right before the newest update, magic!!!! It started working and saw 4g LTE icon and had bars. Thinking that it was finally fixed I went ahead and installed the newest update which was pie thinking all was good. And yet again lost connection again.
Im getting "NO SIM CARD" on the lockscreen. Also, when I go to Network Mode I can't change from "Global" to "LTE/CDMA"
I went to Verizon got a new sim still no luck.
Any advice???
-------------------------------------------------------
-What is the dialer code or is there an app to force the network type to LTE/CDMA?
-Does anyone have a pit file for the v5 bootloader?
TLDR:; Cant get phone to connect to cell tower, says no sim card but got new sim card. Can't change the network settings from global to lte/cdma
Hello! My phone lost ability to connect to 3G and 4G networks. Only 2G work. WiFi works also. I am now with LineageOS 17.1 I flashed it 2 mount ago and it works without any problem. Also MicroG, not Google play services. But one week ago it just lost ability to connect to 3G and 4G. The triangle is empty. It's not possible to scan for another mobile providers when the phone is forced to stay in 3g and 4G and using combination *#*#4636#*#*. The IMEI and IMSI is present. I flashed via TWRP several radio modems without result. I checked internally the phone - there are cable connections, visually is ok. I tryed different Rom - Resurrection Remix -Android 8.1. Again the same problem.
Thank you for your time!
