Sensation 4G "airplane mode - Your SIM card does not allow a connection"

Hi,
I'm having "this issue" with my Sensation 4G.
I bought this second hand phone in US and bring it back to Venezuela. The phone worked swell with local carriers but suddenly lost signal and got the infamous “Your SIM card does not allow a connection to this network” message. I was on stock ICS.
So I've rooted my phone. used HTCdev, juopunutbear, clockworkmod, installed Superuser and got super CID. Also, I called my carrier and checked that my IMEI was not blacklisted (just to be sure) and flashed with OrDroid 9.0.0. Nothing changed. Next I did the SIM unlock and no results either.
Yesterday I took the SIM card and left the phone without battery. Today I turned it on and found that airplane mode was on, so I tried to turn it off. Nothing happened. In settings the airplane mode is greyed out and "turning off". If I try to make an emergency call the phone shows the "turning on radio" message and the only option available is to reboot. If I go to the phone info menu the radio is off but can't turn it back on.
I read that flashing new radios could be a solution but I'm not sure what radios are best for my phone and how to do it.
I really need some guidance over here. Any help would be much appreciated!

[Q] Need help with connectivity issues. DESPERATE

Hey guys, quick background. I bricked my SGS3 and had to have it replaced. I think I got a refurb phone because from day one I keep having the same issue. First day I got the replacement phone I rooted it and flashed CleanROM 5.0. Everything was peachy until I noticed that I have no 4G or 3G service. In fact, I had no data connectivity at all. My phone can make calls, receive texts no problem, won't connect to internet. If I restart the phone, I have 4G right away. After a few minutes, the 4G icon is on, but the phone won't has no data connection (when I say data connection I mean it will not go online, no internet, no android market, still have voice and txts). If I attempt to go on internet, I get a message saying "No Signal Found For Mobile Networks". I have installed Network Signal Info and right after a restart it says 4G LTE, data connected, upload+download activity. After a few minutes, it says 4G LTE, data connected, after a little while, it will switch to EHRPD, with data "connecting". Also, in the System tab, it will tell me my IEMI and version of JB running, next to "Radio", it says "unknow". WiFi works perfectly btw. My IEMI is perfectly fine,
I had it backed up. My phone number is still there.
Here is what I had tried so far: Switching into and out of Airplane mode, different programs that reset mobile connection, flashed different custom ROMs, flashed the stock kernel, flashed 3 or 4 verizon Modems, Data wipe, cache, Dalvik wipe, Odin'ed back to stock 4.0.1 ICS and had upgraded it to 4.1.1 via verizon software update, changed the SIM card, and reprovisioned the phone with that *3767*whatever the hell code. I'm out ideas.
If anyone has any other idea that I can try before I take it back to Verizon, please, let me know.

Did you go into your mobile data settings to make sure you're on CDMA/LTE? If not I would select and reboot the phone and see if the problem persists. I don't know if you have tried this but it's worth a shot.

I'm having literally the same exact problem with my mom's S3 except for it's not rooted, complete with 'download + upload activity' and 'unknown' radio. I've yet to find anything in my search, but if I do I'll post it here.

I did try that. Nothing seems to be working.

[Q] Nexus 5 will not automatically connect to cell network

Hi All,
I've been having an issue after upgrading from a Nexus 4 to Nexus 5 where the phone will not re-connect to the home network (or will only reconnect to GSM with no data) after losing connection. This happens for example when going into an elevator or parking garage; I'll lose signal and when I get back into a signal area it won't reconnect unless I go to the "Mobile networks" -> "Network operators" menu and select "HOME" or "Automatic Registration". I'm using Straight Talk wireless with an older T-Mobile SIM (before they switched to only AT&T). I've called Straight Talk a few times to try and debug this, but the only instruction they've given me is to reset the APN and set it up again, which I've done a couple times to no avail. They claim that the SIM card is good on their end. Any ideas what might be causing this?
Thanks!

It sounds like the Baseband/RIL problems I had with my old LG OP2X with non-stock roms. For me, it was fixed switching to aeroplane mode and back, it could also get stuck there, I remember it once took me half a day to get it out for I didn't want it to wipe it.
Any way, may be it's not the same but it could be fixed flashing a baseband, I think I saw a thread about it somewhere around... Also, flashing the full firmware should —if it's not a hardware issue— solve the problem without doing much research.

Hi Were you able to get a solution for this, My nexus 5 does not connect automatically to the network, it works only for manual search.
Please help...

Same problem here. Any solution?
I'm stuck with out any connection for the las two days. Tried removing battery, airplane mode. manual search. nothing.
Tried my line in other phone and it worked, other line in my phone and it didn't.
S4 I9500. Paranoid 4 Beta 4.

I don't have a really good solution, i reflashed my phone to stock and it did not fix the issue. I ended up switching carriers to T-mobile and haven't seen the problem since. It seems it was a SIM or network problem like i suspected

LG G5 Sim not detected only for SMS and calls

As stated I'm using the LG G5 H830 T-Mobile variant. I am getting 4G LTE data connection and everything runs well (Not in any WiFi range) Yet for SMS and calling as well as mobile hotspot I get "No USIM card' error. This happened after wiping the system and formatting data. Rebooted recovery (as per instructions on forum) then installed the stock firmware & Patch with systemless root and xposed. After this I did factor reset when just pulling the sim didn't help. Still nothing. I reflashed just the stock firmware with TWRP and SuperSU and issue is still happening. I've disabled rebooted and enabled the phone radio. SIM is in good condition and tray as well everything is SECURE and should be good to go.
I'm assuming a new SIM might be a solution. But I'm not counting on it and with Labor Day tomorrow for me I wouldn't be able to pick one up for 2 days. So here I am...hoping someone might have a fix. I know I don't have many posts on here. But I am an experienced user....just not with the more basic of problems I guess
Thanks!!

Has anyone else experienced this yet? I'm just curious...I had it fixed for a couple days. I've formatted data and done complete system wipe. Tried it resetting phone with the COMPLETE zip and TOT using LGUP. I'm receiving texts. Not calls. Not able to send either. I've activated new sim, didn't help. LG support just told me to look into warranty. T-Mobile needless to say just wanted. Sim card does show stock tmobile short code contacts but phone number shows as unknown. Hotspot won't work. I've tried setting the phone number to the sim. Nothing.
Anyways. I don't think I messed with anything, even so I've done everything to start the phone from scratch. Going to replace it, just more or less curious at this point and maybe others have had the same issue.

I believe I had the same issue as you and it was driving me crazy. I was constantly wiping data, system, etc but my phone kept giving the message "roaming indicator off" where it should show the name of the carrier. This resulted in me having LTE data and that's it- no 3g, no phone calls, etc. I couldn't even access the mobile network menu.
What ended up causing the issue was the network mode setting under wireless networks. Keep in mind at this point I'm running a patched rom which now gives more options in the network mode menu than the phone came factory with. I have an area at work where I have to switch to 3g, GSM/wcdma preferred network setting, because although I have full LTE signal, my connection goes dead. When switching back from 3g I chose the setting lte/CDMA thinking this would force my phone to stay in lte mode due to another area on an upper floor where the phone will constantly drop lte.
Anyways this resulted in my phone saying roaming indicator unavailable, the inability to make or receive phone calls, and either the mobile networks or network mode menus being grayed out. When stuck in this mode there is no way to put the phone back into the standard "GSM/wcdma/lte" mode. Even a complete reflash won't fix it. I even used lgup, which worked for maybe a day until it force closed the phone app and went back to roaming indicator unavail. I wiped every partition and even reflashed radio firmware. Nothing worked.
What ended up fixing it was using an app called v10 hidden settings which allowed me to access the network mode menu directly and re-choose the lte/wcdma/GSM setting. Incidentally on first access to this menu through the app there are only two network settings available. Once you choose a GSM setting, the rest appear.
I'm not sure if this was your issue but I hoped this helped because this took me about a week to workout.

Cell service won't connect when roaming with Lineage OS on Sprint, works with stock

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.
