My wife's VS985 G3 was getting bogged down and freezing, etc. Decided it was time for a factory reset to try to get a little more mileage out of it. The phone is running the latest stock Marshmallow, non-rooted. Performed the reset and rebooted and got a message that the SIM was not readable. Never had this problem prior to the reset. Shut down, removed SIM, replaced SIM. Same issue. Got a hold of Verizon and they had me reset the network settings and reboot. Started seeing 4G but then lost it again. Verizon said we needed a new SIM. My wife took the phone to a Verizon store and they replaced the SIM but it only worked for a few minutes and then went away again. Later the SIM was working for almost a whole day, but again stopped working.
I saw the thread about some people having this problem and the slip of paper trick, the battery possibly being the culprit, and trying to tighten the screws on the phone body. Haven't tried any of this yet, but I also noticed the for the people that did have this problem it just started happening randomly. I didn't see any mention of the problem occurring immediately following a reset. This makes me think it's a software issue.
We ended up getting a new phone to replace this one so I'm thinking of downgrading this phone, rooting it and trying a custom ROM.....thinking this may over-write whatever software/firmware problem could be causing the issue. Sound like a plan or am I way off base?

I have been running custom roms on my droid since the root explot was first discovered, and I have a rooted xoom as well. Last night I rooted my thunderbolt and installed the debloated rom. I don't think it is even related to my problem, as it still worked fine after doing this, but I thought it was worth mentioning. I removed the sim card today, just to prove to my brother that it did indeed have a sim, and after reinsertation, my thunderbolt has not been able to connect to a data network. I do not live in a 4g area, and I have tried reseating the sim several times. I can make phone calls, wifi works fine, but I cannot get the 3g icon, and the browser won't load if not on wifi.. I'm starting to get scared. I can't think of anything else to try. Any suggestions?
EDIT 1: I have intermittent 1x data, but I never get 3g. And when I say intermittent, I mean I get it like right after a call for maybe a minute, then it goes away.

I had this same issue as well when I removed and reinserted my SIM card. When I booted back up I was stuck on 1xRTT. After making a call, they phone locked back on to LTE and everything was good after that. If it still isn't working I would recommend giving Verizon a call. They may be able to reactivate it. I did notice that the problem persisted even though I flashed a couple different roms on the device. I'm thinking it probably isn't a great idea to remove and insert the SIM if you don't have to.
Just an update,
I spent 2.5 hours at the effing verizon store today after spending an hour on the phone. Even after all that time, and giving me a new SIM, they STILL couldn't get my TB to connect to 3g. They said that it might magically start working at midnight for no particular reason, but had no clue what to do (I was actually at a corporate store btw) If it doesnt start working tonight, I am going back tomorrow. I have no idea what the hell is up. I am very tech savvy, and this is just insane. It must be a verizon problem in my area that it wont let the phone reactivate for the 3g/4g
Hello,
I have a random/erratic problem with my SGSII reporting that the baseband is unknown and no IMEI being present.
It happens randomly through the night, or if the phone reboots itself, the signal icon changes to a circle with a line through it, and no network connectivity works (except for WiFi).
I've backed my \EFS up previously and restored that with no luck, re flashed my modem with no luck.
Usually the fix is to reboot the phone a few more times and eventually it comes back on.
I've got an app called 'network' which gives me various stats on the connectivity type etc (from my nexus one days) under 'Set preferred network type: I have an extra entry called 'Unknown' which gets selected by the phone, and changing this to one of the GSM variants doesn't have any effect.
Like I said, it's random and not much of a show stopper right now since I'm thinking it's a software problem. I don't want to RMA my handset just yet.
I have seen some other threads where people seem to have this permanently and there are no resolutions provided in the threads.
Has anyone else experienced this?
Kind Regards,
Chris.
I m relieved to know someone else also has this problem. Last Sunday my handset just hanged on lockscreen, so I pulled out battery, reinserted it and sim stopped detecting, so I tried couple of restarts, factory resets still nothing. So flashed firmware a couple of times still nothing. So when I checked if firmware was flashed correctly, the baseband was showing unknown and IMEI was completely blank. Handset is still in warranty so I don't want to take any chances, I am sending it in on Monday. Will keep you posted on what happens. Let me know if ur problem is solved.
Phone started regularly reporting that the SIM wasn't inserted so a quick phone call to O2 and a courier is coming to pick the handset up tomorrow.
Still under warranty so they should be able to fix/replace it.
Pain in the backside though to back up everything and then reinstalling it again when it comes back (either repaired, or a new/replacement one)
Right,
I got it back.
Apparently they identified it as a faulty SIM card slot. I was sceptical of this at first, but I persevered with it.
Surely enough, 1 day into using it, the same happened.
Back to the repair centre with photographic evidence of the problem.
Same happened to me a few night ago, removing the sim and re-inserting it fixed the problem for me.
I haven't seen it again yet.
I was on the stock firmware and insecure kernel.
me too... never been update or using any clockmod firmware..it just suddenly happen... any other way to fix this...
I'm also having the same problem for days now. My phone is full stock, never rooted it, never installed and unsecure kernel.
It randomly loses IMEI, Baseband and GSM signal. Sometimes it comes back after rebooting phone, but sometimes it seems to be permanent.
Was just casually using my Amaze today with the official CM10 I've always had on it, and all of a sudden in the middle of a call the call dropped and the phone restarted. I thought it was just a random reboot as they are nightly builds. After it restarted there all of a sudden was no signal. I was a bit confused as just a minute ago before I started the call I was getting full bars on 4G. I tried rebooting multiple times, changing SIM's (the phone is unlocked), even trying different ROMs. All of them had the same problem. No cellular signal. I tried the *#*#4636#*#* to set the network to WCDMA, however it was always stuck on "unknown". No matter what I changed it too it would always reset back to unknown. Then I finally thought I had to resort to an RUU.
After reflashing the Mobilicity RUU (stock one that came with the phone) on gingerbread, the signal FINALLY worked! I was so relieved and went to download the ICS OTA update so I can start flashing ROM's again. Then all of a sudden in the middle of the update the phone restarted, and when it booted back up again, no signal again. I then went to check for software updates again and just wanted to try downloading it over WiFi. I accidentally clicked the phone info screen instead of software updates and I noticed that the IMEI, IMEI SV, Phone Number and IMSI were all "Unknown". This was really odd. *#06* also brought up an empty IMEI box. Then I clicked software update and it said there were no updates available. What? It just worked a while ago before the signal broke again!
I then pulled the SIM out to run the phone WiFi only until I could figure this out and I noticed that it wouldn't say "No SIM" with no SIM card inserted like it normally would, but would continue to say "No Service" as if there was a SIM but there was just no reception in the area.
I've been trying all day to flash multiple RUU's and the only one that fixes the problem is reflashing factory Mobilicity GB RUU. Then signal works again, however after any restart signal will break again and won't work anymore until another RUU reflash. Is there anything I can do? This is the only phone I have to use and it's driving me nuts! Any help would be greatly appreciated!
Please acknowledge that I am not asking for a way to obtain or change my IMEI, as I know that is not allowed. I am asking for a way to fix the No Service issue I've been having.

Now another thing has arises. I try to use it as an iPod/Media player now and just use it connected to WiFi. However the battery dies after about 5 hours of just standby, untouched. It's all because of "Cell Standby" using up battery. It uses up 4 and a half hours of battery and 100% of the time it's without signal. However, even if airplane mode is turned on to disable the cellular radio, it doesn't make any difference to Cell Standby.

I have had this issue twice ... first time it happened maybe 9 months ago and stayed like that for 3 weeks with me constantly flashing and wiping and s-offing no no avail ... one day I pulled out my sim and memory card and when I switched on the device it says "no simcard" it never said that b4 so I switched it off and put back in the sim card and memory card and poof it was suddenly working again...
The first time I recalled not installing anything for months before that event other than one app..... "What's App" I installed what's app and used it fine for 2 weeks and the phone just dropped in the middle of a call and never regained signal.... so I said since that was the only app that I had installed its probably the culprit, so I will never use it again since the phone started working again.
Sadly 7 months later a girl i was talking to kept insisting that I install whats app because she wants to chat more... Against my better judgement I went ahead and did it and it worked for 2 weeks and one morning .... poof "no service" no imei .... and the culprit .....? WHATS APP!!! sadly I have been in this state for a month now with no sign of it fixing itself again... thank you whatsapp... let me know if whatsapp was installed prior to your loss of imei

Actually my Amaze started working again as well! One day around two weeks back all of a sudden it decided to start working again, but I just left it there as I had already bought an Xperia ion to replace it. One day my friend asked if he could borrow it for a week or so, I let him and when I popped his sim in it worked, checked imei, apns, everything was good. However later that day during the lunch hour he took it out and told me there was no signal. First thing I did obviously was check the imei and of course, it had disappeared again. Nothing in window when typing #*06# and in settings imei would say "unknown"
I never used whatsapp before and he doesn't use whatsapp either, it's never been downloaded on the phone so it's not the problem for me. If I reflash GB RUU it will work again and imei will come back BUT only until you reboot, after reboot it will lose imei again. Honestly it seems to have a mind of it's own when it comes to working or not.
I'm Having the same issue right now anyone have any ideas?

Having the same problem too!
Tried removing the sd and sim, rebooting without, reinstalling them, rebooting with, and no luck.
I'm planning to flash the Debloated Stock rom to try that, then I'll try the latest RUU, will report back... (could be a few days)
Debloated stock did not work. Latest ICS RUU did not work. Original, very first, RUU didn't appear to work until I did a restart (without the Sim inserted).
So it's working for now, although it's Gingerbread...

Really? I've tried literally every RUU available for Amaze and still nothing. Before, after flashing a gingerbread RUU the IMEI would work during the first use but would break after restarting. Now when I do any RUU, IMEI won't work under any condition.
Hey everyone,
I've been delaying action on this but the OTA update got me into gear.
For the past few months i've been having an issue where my phone will drop from 4G to 3g, and a SIM icon with a ? will show up. Toggling airplane mode or restarting the phone fixes it. Because I wanted to dodge today's OTA, I went ahead and rooted via STUMP, but the issue is hard to reproduce (i have a screenshot). I always ensure that my network is set to LTE/CDMA instead of Global, but it almost feels like its auto-switching at some point (maybe when the signal drops)
Im thinking next step is to get a replacement SIM from VZW. My fear is that the SIM wont fix it, i'll need a hardware replacement, and the one they give me will have shipped with ioRoot/stump/bump patched.
Anyone have this issue and resolve it completely without a full replacement? If so, how? Ive tried a battery pull but that didnt help, ive never removed the SIM on this phone
Thanks!:laugh:
Happened to me before and I ended up getting a new SIM from VZW and then activating it and it didn't have an issue after that.
Not with my G3 but with my RAZR MAXX

Awesome - that is great to hear, would much rather get a new SIM than a new phone, ill drop in a store and see what they can do for me

Just so you know, I was recently having some strange 4g to 3g drops (you can read by thread in this same Q&A section). They were under very different circumstances, but one thing that remained constant was not amount of resetting or reflashing other roms fixed them. After exhausting all other options and thinking I may have to try and get a new sim to see if that fixed things, I took a last ditch effort and used the .tot file and lg flash tool to fully wipe the device back to 100% out of box stock. After doing this my issues have vanished. I'm thinking something got seriously hosed in the radio somehow, and granted I never got any "?" notifications so it's a long shot at best, but something you may consider if all else fails!
If you have never pulled your SIM before, you might want to pull it and reseat it a few times, just to make it self-clean. Save a trip to Verizon, maybe.

I have an Samsung S9 Plus that was an AT&T unit (I think) and I flashed it over to the global firmware so I could use it on Visible (Verizon). It has been working for months, but I have now had this problem happen twice. I get up on a Monday, and notice that my phone has no service. I think it says "No Network Connection" or something like that. The first time I tried many of the usual steps - switching airplane mode, resetting network, wiping the cache, long support chats with Visible. What finally got it working again was putting in another sim(from Red Pocket - AT&T). That made the phone go through a reboot to swap over to the new sim. Then I put the old Visible sim back in. The phone does another reboot, and now everything is working again.
Is there a way that I can get the phone to go through this process without swapping the sims? I would just like to know if there is a more efficient way of fixing this problem when it pops up.

Call your carrier and have them to a reprovision. I had this happen with T-mobile coming from Sprint.. They will have you turn off the phone, do something on their end, and after that it should work.
Just to update, I have switched over to ATT Prepaid. Since the change, I have not had the problem happen. I think it must have been an issue with Red Pocket. Either that or something that got fixed with an update. Just putting these data points out there for anyone else that is having issues like this.
