so my simcard on my phone suddenly doesn't work (it says invalid sim) after a while. it always work when I restarted the device. but it's kinda annoying to restart every period of time. I've tried suggestions from the net but nothing seems working. I've also tried switching sim on the same provider but the issue persist. do you guys have any suggestions?

my t-mobile Vario II crashed the other day as I was replying to a text message, nothing unusual there, wm5 has been known to crash once in a while.
so I soft reset it, and it reboots.
But now, after it's all finished loading, it would run for a few seconds, only to crash again.
I reset again, but the freezing up follows shortly.
Nothing I do stops this happening.
So in desperation I go for the Hard Reset.
Everything gets wiped and it reinstalls all the T-Mobile stuff.
But now I have no signal,
I take the SIM card out and put it in an old nokia, and that works fine, i receive two text messages which I think were due around the time of the first crash.
The texts are normal texts from friends, saying hello and stuff.
So it's not the SIM card, it must be something to do with the phone.
I've just tried the SIM card in the phone again, and i notice on the T-Mobile boot screen it says the usual stuff.
M 05 S 04 B 06 D1.21, but just before it blinks it says No GSM.
I searched the forums and, this seems to be a problem people can get when tryting to unlock or upgrade their phones rom.
Problem is, I've not tried to do either.
Any help would be greatfully appreciated.
Am I going to have to mess around with ROM upgrades, all of which scares me greatly.
Or should I just send the phone back to T-Mobile for repair.
quang.
I've just checked to see if i can read the contacts of the SIM card.
Tapping on SIM Manager doesn't work,
nothing happens.
Which leads me to believe that maybe the SIM reader on the phone is damaged in some way.
Hi there,
I have this strange problem with my HTC Elf. The problem existed with the original ROM (5.0) and after my upgrade to 6.5 as well.
It started once a Month, but now it's twice a day.
If i receive or make a call, receive or send a SMS the device just shuts down immediately. (like a hard reset).
The device then automatically starts up, i get the "Smart mobility" screen and then it starts over again. The boot cycle runs endless, until i remove the battery and start again. Sometimes i need to remove/replace the battery 3 or 4 times to get it booting up again. (Doing this booting drains a lot of battery power)
If i remove the SIM Card, everything works fine for hours and booting isn't a problem at all. So I believe accessing the SIM Card somehow craps the device out. The boot-cycle seems to happen in the last stage of booting, when the device first tries to access the SIM card. (That's something i have to suspect, cause there is no way to log the booting).
I don't believe that it's connected to the ROM Upgrade to 6.5 i did, as the problem happened in 5.0 as well... (btw. everything is much faster and more light-weight since the 6.5 upgrade. It's just great.)
Here are my questions:
- Is there something, I could log the boot process, to see what's the last action when it starts over again?
- Is there something like an event log in windows, where I see the last action or even failure / exception, before the device restarts while doing a call / writing an SMS?
- Did anyone see this happen before?
Thanks for any input!
Hi
Have you tried to change the Sim card or use another one just in case the sim is the problem?
Hi Tito,
I plan to swap SIM's next weekend. But i don't get how a SIM can crash the whole thing. I would understand getting errors like "Can't read SIM" but auto-resetting the whole device?
Anyhow, I'll post an update after trying another SIM. The whole thing is, that it's not reproducible by a specific action one could take. So if the device keeps up even for 2 days with a spare SIM - that doesn't mean the SIM's chip is the problem. Just an indication...
Thanks,
mc
Hi
Please do post the result
I had the same problem (endless reboot) on my Elf. I solved it by replacing the battery.
Hi,
well it's like always. If you need the problem, you cannot reproduce it.
The device wasn't crashing even once on the weekend.. Either with my own SIM or with another one.
The battery thing is interesting. As soon, as the problems start reoccurring, I've got now a spare SIM card to test. If this fails, I'm able to test with another battery in march.
I'll post any results.
thanks,
mc
I have the same problem...and also struggles to find a signal. Did you solve the problem yet?
same problem
I have the same problem and !!!!!!!!!!!!!!!!!
well, the thing is i upgraded to the HD2 and didn't use my elf pretty much lately.
I changed my provider and got a new SIM but that didn't solve the issue. So I can exclude the fault being in the ROM or the SIM card.
When the elf was crashing I couldn't start it up. It was booting, and as soon as it tried to register itself in the Network, it crashed again. However, when connecting it to a power source (charger or pc) and booting it up, it went fine through and was able to register in the network.
That brings me to the idea, the even if the battery is full at 100% it might have a flaw and doesn't bring enough energy, when the device is scanning for the available networks.
So next time, I'm in china, I'll get a new battery pack for my elf - however, it's no more that important as my HD2 is running pretty fine.
Hope it's something which can help you.
cheers,
mc
i have been this problem for months, In the EM application RD test it shows me the when i check SIM LOCK , "ERROR 213" ,
can any one tell why is this?? i cannot use my sim card. big problem.
I have the same issue after updating through zune.... Havent had any issues untill connecting my phone to Zune last week...
Did you fix the issue?
I had similar problem, but it's not all the time, it says sim card rejected, but not all the time, If i reset my DVP it will behave normally again.
anyone found a solution?
Hi,
I've got a dual-sim Galaxy S7 Edge (SM-G935FD) this spring and everything was fine until a week ago my second SIM started to disappear randomly. Basically I wake up the phone after a while and I see no indications of the second SIM: no signal bars and "No SIM card in slot 2" message in settings. Rebooting the phone sometimes solves it for a while -- the second SIM becomes visible and works as expected but after a few hours it disappears again.
Things that I have tried so far:
wiping out cache partition
forcibly setting second sim to "2G only"
manually choosing mobile operators for both sim cards
swapping sim cards -- problematic sim card would still disappear after a while, now from slot 1.
putting the problematic sim card into another phone -- it works just fine, not disappearing at all.
factory reset
The issue still persists. Currently my first sim (the one which works well) is set to "auto (4g/3g/2g)", also mobile data goes through that card. My second sim (the problematic one) is set to "2g only", although setting to "auto (3g/2g)" gives same result.
My software:
Android 7.0
ROM: G935FXXU1DQEJ
Build: NRD90M.G935FXXU1DQGN
Would also mention that examining the phone logs via
Code:
adb logcat
while the card is invisible didn't reveal anything suspicious...
It appeared to be a bizarre SIM issue: after replacing the SIM I haven't seen such behavior for more than a month. It's weird that the SIM would fail sporadically and a reboot would fix it, also that it would happily work on other devices. Anyway, this is hopefully solved now.
Just picked up one of these phones. Really like it so far! One issue I've noticed though, after a few days of ownership, it's randomly dropping/not detecting the sim card? It's happened at least twice where I've left it to charge over night and woke up to the no sim icon, and yesterday at some point while I was watching YouTube videos in full screen (in my hands, off charger, no notice of the drop either whenever it actually occurred). Quickly popping the sim tray out and in resolves the issue. At first I thought it was because I was using a manually cut sim card, so I've since replaced the sim but the problem persists.
Anyone else have this issue? Should I have the device exchanged?
Thanks
First the phone froze and after restart dropped sim
I just had the same issue occur just now. The phone had frozen for over an hour before I did a forced reset and now when it started back it shows no SIMCARD and no connectivity. I am like you, I really like this phone but hopefully this isn't a permanent issue.
Watched it happen just now. Goes from bars to no sim icon without error or notice. Resetting the network settings, resetting the phone, and powering it off/on won't fix it. Literally have to pop the sim in and out and its recognized right away.
I lost sim recognition after I flashed to LOS 11/30 and no matter what I tried, phone would not recognize the sim. Once I flashed back to stock, it came back. Hopefully this was due to the rom and the problem won't come back.
I am not sure if I lose the SIM, but I will say that when I am driving around with Android Auto, I constantly see the cell signal go from LTE to no signal every couple minutes...

Click to expand...
Click to collapse
Had same issues when I flashed back to stock I actually have better signal than when I got it out of the box.... Almost as if the software wasn't installed correctly or something
Same here I'm on the stock room. I'm wondering if it is an app I downloaded. Any idea how to wipe cashe not the apps but system.
This is happening at least twice a day now. It seems to be software related. Power off and on without taking out sim fixes it.
