Hi all,
Just got home, looked at my mobile and it said there was no signal - so I turned it off and back on again, then it said there was no SIM inserted. Keep restarting the phone, keeps saying the same thing. Why?!
Am going to try it in my old SE K850i to see if it's the SIM card or the phone at fault.
In the mean time, does anyone else know of this fault and how to fix..?
I didn't the drop the phone or anything, it was just in my pocket, on it's own - like it always is!
Cheers
Tried it in my K850, works fine. Please someone help
yeah i usually dont put the sim card all the way in but slightly in and it works
I've re-opened this thread due to me misreading....DOH! Apologies (Mental note to one self.......follow own advice and read before posting).

you could try to clean the contacts on the sim card connector of the phone with a q-tip, and see if that solves the problem.
also check if any of those contacts appears to be bent or something, and so doesn't make a connection with the card.
Everytime I open the back up to remove the SD card, I get the SIM card missing bit even though I have not touched it! My HD is only 3 months old and it has done this from the start. I just have to remove it a bit - shove it back in and the phone accepts it is there. Annoying but not enough for me to send it back.
hmm, maybe try to make the sim a bit thicker so it doesnt move around (it shouldn't move by removing the back cover, but it seems to happen on your phone / sim combination.
try putting a thin piece of paper on top of the sim (not the contacts side, but the side facing to the battery cover)
maybe that prevents this problem?
Missing simcard
I have the same problem with my simcard. Though something strange happens when the phone is off for more then 10min, it works fine and notices there is a simcard for like 30 sec after which the error pops-up again. I have tried all of the above things, my simcard works fine in my other phone, adding some paper to thicken it doesn't work either
Anyone who could help me with this?
P.S. sorry for the bad english
As in post 7# written, put some papersheet in the simholder above your simcard to increase the contactpreasure. This surely helps.
Tis trick is also useful for all dualsim users who thik the dualsimadapter does not work in their device (but after using this trick get astonished!)
for Thysiey:
Try to switch to Gsm mode to test . Maybe you have bad umts signal? Happens at other places too, or only at one place?
Got the same issue here...
I cannot move the SIM because it is being hold in place by the battery. (to little room)
Adding a piece did not work either.
Anyone got another solution?
anyone? My mothers HD just got this problem now. She has a new phone and for the contract renewal she had to read the backside of the sim. The phone all of a sudden didn't recognizes the simcard anymore.. I tried a few other simcards but it won't read it anymore.
My plan was to sell the old phone but now it's almost worthless just a shame it is still a great phone to operate.. handy with the navigation and all
Hi, I recently purchased a Dell Venue Pro and I am going to get it some time this weekend. The main concern I have with this phone is the small amount of storage. 8gb is simply not enough for me. Perhaps I missed something, but I've been reading through this forum and haven't found a very good explanation for newbies on how to replace the SD Card. I have actually seen some posts that say that they managed to exchange their 8gb SD Card for a Sandisk 32GB micro SD card Class 2. However, I would like to have some guidance and instruction from someone experienced doing this; I wouldn't want a bricked Dell Venue Pro.
Therefore, could anyone please instruct me with a step by step guide on how to replace my SD card without crashing my system and which sd cards are compatible? Thank you.
Believe me when I tell you this will not work. What you will end up with is a bricked phone that needs to be replaced.
If you have a device that was shipped between December and now you don't have an engineering sample, those are the only devices that can actually format the sd card to the proper filesystem and lock the card down in way you'd expect it to.
If you'd like to test that theory, simply replace the card while it's off. Perform a hard reset on the device (the CAM + VOL DN combination does not work), shut it down and put the card back in an SD reader. It won't be formatted and won't be locked down.
You might be able to format the card on a Windows CE machine with storage manager, but the most I've been able to do is get the SD card test to show a 114 not ok instead of a 115 not ok.
After that, if you're lucky, you'll be able to simply throw the old card back in the device and proceed with enjoying your phone with the original SD card. If you're unlucky your phone will not boot.
Food for thought:
In the diagnostics application there is a button for "Service Center" which displays two boxes: Zune and Composite.
When you press the CAM key during boot this puts the device into a "restore" mode that Zune is supposed to work with at some point in the future.
I'm guessing if we can figure out a way to flip the mode to Composite (currently requires a password) that the "test/debug" bootloader will allow us to format the cards properly.
It's also entirely possible that the reason the engineering samples work and the retail devices don't is that the eng samples are in this mode already.
Wow thanks a lot for the very thorough answer. Do you think we will see memory expansion as a possibility in the near future?
Ok, without trying to insult anyone, 'm gonna call Bullshxt. I now have 3 VP's in my possession. Ok....1 I dropped and it doesn't start any more. But that still leaves 2. On both of them I have removed the SD card, replaced hte card with bigger and smaller SD cards and have even left the SD card slot empty. I have NEVER bricked my phone.
Let's leave performance behind first...and not consider it. Lets just talk about changing cards.
The key to changing cards is process. Take the card out and restart your device, it won't boot. there is no external keys for hard reset. Place that same card back in your device, it will start.
To change out a card, do this:
1. Hard reset your device
2. On the reboot portion, remove the battery and then remove the card
3. Put the battery back in and let the device start up
4. Walk through startup and your phone is ready to use.
Keep this same process each time. You cannot remove a card, without first going through the hard reset process. You cannot add a card with out first going through the hard reset process. The hard reset process initializes the card to the device.
I've done this at least a dozen times, with cards ranging from 2,4, 8 and 16g. I've done it with cards pulled out of Google phones and an HD2. I've done it with cards that have never been used before. Its 1, 2, 3, 4. No matter what combination of removal and add....1,2, 3, 4. Remove a card, its 1,2 ,3, 4. Add a card, 1,2,3,4. Simple.
Now...if you want to talk about Performance....thats another conversation....
Again....no insult intended with the BS call.
Sorry...forgot to add 1 thing.....this has been described on this forum several weeks ago...so...what I'm saying is not a huge discovery from me...but rather from the guy that posted this around christmas.....I just repeated it is all !!!
Oh OK, sweet thanks for the thorough step by step guide! This is exactly what I needed.
A few questions though.
On step 2. you mention a reboot portion. What does that mean? After hard resetting what is my "queue" to remomving my battery and SD Card
Also, you never state in the 4 step process when exactly I put my alternative SD Card in. Would I put it in step 3 when I put my battery in?
Finally, you say Performance is a different story. Are you saying that replacing SD Cards will make the phone slower or more prone to crashing or working less stably?
Thank you.
I think once the phone is ready to use again, you then start the process over again at Step 1, except instead of removing the SD card in Step 2, you put the new one in.
What I want to know is, if taking out the provided SD card voids the warranty, how do you get a new phone without paying for it? Or does the warranty not cover that specification?
none taken, but your claim about the device not booting if you remove the card is false.
It will boot, sans card, with ~15mb of free storage space with no customizations. It's also likely though that if your device does boot into this state, you will never be able to get another SD card to work in it ever again.
Even if it boots into the "no storage" state it's still possible to put in the old card (in most cases) and have it work. I'm just saying that has not been the case for everyone.
Looks like I've found quite a good amount of posts from people stating that they have swapped SD cards succcessfully so might try this if I feel like I require more storage. Would anyone happen to know if there are certain types of SD Cards I should use to make this work? Also, alodar1, you have stated something about performance being another story? Would I be sacrificing performance by swapping cards? What kinds of issues would I be having?
1) Open settings-> about menu in phone
2) Press "reset"
3) Press "yes" twice. The phone will start to reboot.
4) Wait until the phone shuts down and begins to reboot, and take the battery out. NOTE: If you take out the battery too early, it will not work correctly. I waited until I first saw the Dell logo pop up and then pulled the battery, and that worked.
5) Remove the old SD card (I used a very small eyeglass screwdriver to gently pry it out since it isn't spring loaded)
6) Put in new card, replace battery, restart phone
7) Go through the setup process
That should do it. My phone hasn't crashed since I replaced the card on Sunday, so its been a success for me. I have not had any performance issues with my new card - but I suppose that really depends on your card. Granted, I actually downgraded - I went to a Sandisk Class 4 8GB card. Soon enough I'll be getting a 32GB card and trying that one out.
Ah things are much clearer now thank you very much, will try this. I'll pray my phone doesn't go bad... gulp.
Also, are you saying you were a victim of the crashes and replacing the SD Card fixed it?
OK so I'm going to buy an SD Card, a 16gb, so should I go for a class 2 or class 4? What's the difference between the two and is any one of those two incompatible with the venue pro?

Yes - my phone crashed very frequently with the 16GB card. Many times a day. I've now gone a full week without a crash with the new card.

Mine is class 4. The problem here is that there is no official specification. The class rating refers to data transfer speed - but the requirement for Windows Phone 7 is random access speed, which the card manufacturers don't advertise. Early reports actually showed that higher class (6+ cards) actually perform worse in WP7.
I don't have the DVP yet. Will the warranty be void when the SD card is replaced/removed? Thanks.

Yes, the black tape shows "VOID" after you remove it. A prior warning would be nice, since the tape doesn't say that on the outside.

Does it really say "VOID"? I removed the tape but I can't discern any letters left on the device. However, I can see an "O" on the tape.
yep, it says VOID and the black VOID letters are left behind when you remove the sticker.
So for those who have replaced their cards, how is the phone holding up? Able to use wifi and the marketplace and IE with no crashes?

sorry for the delay in replying. No, not necessarily. Personally I believe there is an issue with the specific cards Dell used. But what do I know for sure. I swapped to another 16g card...nothing fancy...just directly out of the HD2.....it worked and performance was better. A couple of friends of mine did a similar swap, looking at specific R/W speeds, class types, etc. They had mixed results. So, my guess is, there is something else that is a trigger that no one has hit on yet. I know my 16g performance is not as good as the 8g performance....in smoothness of card access. If I swap down to an 8g card...or even a 4g card....I can see the difference.....the performance is smoother.
Now, this doesn't say that those people with the 32g cards are NOT seeing that smoothness. I'm saying that I tried this as a test because I had cards laying around....and noticed a difference. The difference strongly indicates the shipped 16g cards are not what they should be. But, this does not mean the 32g cards on the market right now are the answer.
HELP !!!
I tried changing my 8GB SD card to a 16GB SD card. it booted up fine everything seemed ok, but when I restart the phone it loses all settings. So I put the original card back in, followed the same steps. Now my phone only sees 16 MEGABYTES of storage, I've tried multiple factory resets, after a reset it doesnt even go through the normal setup process. All it does is go back to the homescreen with only the normal tiles accept all the newsroom, tmobile family room and stuff isn't there either. If I pin an app to the start screen then restart the phone the pinned app is gone from the start up screen can someone PLEASE help, I'd be happy just to get it back to normal, with the original SD card in it
Hi all, I have strange problem with my S4 GT I9505. I read various forums and searched but couldn't find a similar case to this strange problem. I am quite new to android and hope that maybe somebody of you would be able to help me or point me in the right direction to solve the issue below.
Issue
I had the phone unlocked from my provider O2 in UK and moved outside of Europe. My S4 accepted the new SIM card for the first 2 to 3 month. At this time my S4 was unrooted. Out of the blue it started with no sim card error, please reboot when using the new Sim Card.
Here is a list of all changes I done but it didn't help
- unrooted: Factory reset Kitkat, updated to Lollipop
- Rooted the phone as above didn't help, installed various custom ROMS, stock Lollipop, Google play edition. After I flashed the ROM I have for a short time network with the new SIM card but then it starts again with the No Sim Card Error. However, I have no problem with my original O2 SIM card.
- Changed SIM card, checked my new SIM card with other phones and it worked, so it not a fault on the SIM card
- Checked with my provider O2 in UK: phone is unlocked,
- Tried to open Service Menu but none of the codes worked, went to EFS folder/carrier/hidden menu and changed OFF to ON, still could open Service Menu to check if the phone was still blocked etc.
Any guidance how to solve this would be greatly appreciated.
Thanks, Frank
Hardware failure. Replace the sim slot. No messing with software is going to fix that.

Thanks, I will try this next, hopefully this will fit it!
No reason it shouldn't, and it's arguably the easiest hardware fix you can do since the SIM tray isn't soldered to the mainboard. Just keep in mind the following: when you purchase a replacement tray, don't throw out the old one until you peel the foam pad off the top of the connector and attach it to the new tray. That pad prevents the connector from popping off the socket it sits in.

I changed the SIM/SD card holder today, however, I am afraid it didn't take long for the no sim card error to return. Only difference today, it connects to the mobile network again after reboot.
The strange thing is, I don't get the SIM card error when inserting the original 02 Sim card, only when inserting a none 02 card (phone is unlocked)
Would this mean that the motherboard is defect?
Most likely, yes.
I just got an Axon 7, and everything seems to be working well. But I set up the "scheduled power on/off" option to shutdown at 3AM and reboot at 5AM, and so far (2 days), the phone has been showing "no sim card" every morning. The first day, a manual reboot detected the sim card. Today, it didn't. After powering down and reseating the sim card, it was detected, but I don't know whether the reboot did the trick or the reseating.
Anyway, does this sound like a hardware or software issue? Anybody else having it?
Happened again this morning. A manual reboot brought it back again. I'm going to disable the 'scheduled reboot' option and see if that 'fixes' it. But it doesn't seem to be a hardware thing, since most of the time, a manual reboot detects the sim. Could it just be done dodgy timing issue in the boot sequence. I'm running the latest B27 US build.

Okay, it's failing hard now. 4 reboots in a row with "no sim card". So I tried the card in my old phone - not detected there either. Can a phone fry a SIM card - because it looks like that's happened.

LG G3 here - half the time after a reboot, it gives me the same SIM card error. After which of course i need to reboot it several times before it will recognize the sim card again.
This looks like a hardware fault, probably a bent pin in the card reader, so i carefully cut off the cover of the reader slot with a dremel + small cutting disc, being very careful to leave the sides of the cover to hold the card in place while it's in - it doesn't seem to be the case, everything looks fine, and from the markings left on the sim card by the pins as you remove/insert it, looks like all the pins are contacting the points on the card itself.
Also very weird that it ONLY happens right after rebooting. The most probable scenario i can think of, is that the card is read on bootup, and not interacted with again during normal usage of the phone...? or maybe a glitch with timestamps? A few times, restoring the backup of EFS partitions "seemed" to fix the problem, but :/
so.... WTF??!?!??!?
Was it a used or new Axon 7?
If used, someone may have had an SD in with the SIM and damaged it.
I was running mine that way but was careful and it survived ok.
Have you tried the SIM in both positions as 1 or 2?
Also ensure it has a correct APN saved against that SIM.
UPDATE: (LG G3) Seems it's a software bug after all. I updated to a newer version of LineageOS, and out of 6 times i just rebooted to test, the "no sim card" problem occured once. So maybe it's not 100% solved, but at least i don't have to futz around for 30-40 minutes to get my phone working again after a reboot.
Hello
A couple of days ago I took out my sim card, then tried to put back in, but couldn't because there was some resistance, so I applied a little bit of force and put the card back. The force was not that much, I don't think I broke any of the sim pins but seems like I did, because no matter what I do sim is not recognized.
How can I make sure there's a hardware problem without opening the phone?
Same problem here. It appears to be something rellated to the IMEI and now I'm trying to recover it using QPST.
