I received my N4 a couple of days ago and had my vodafone (India) sim cut to a microsim. The microsim works perfectly on the iPhone and even on my DHD (along with the leftover adapter) but when I insert it into my N4 and boot the phone, the network signal lasts only for about 5-10 seconds (every single time). It recognizes the sim and even the operator name gets displayed properly in the phone status. After that it's as if there's no sim inserted. Isn't it weird?
I'm yet to try inserting another microsim but I wonder why the phone would reject the sim after a few seconds? Anyone has an opinion or theory on this?
I've tried resetting the phone but to no avail.

My guess would be it is not cut correctly.

This. What did you use to cut it? A template and a scissors? Or did you have a specific SIM cutter that you got from a shop which offered such services? I got my SIM Card cut at a shop which had a specific cutter to cut SIM cards down to size.

The N4 is really picky with cut down sims. many users report problems with cut down sims. Sometimes those problems don't appear till later on. Best bet is to get a real micro sim.

I did the same.. my concern is that it very much recognizes the sim just after bootup but rejects it after a few seconds..

Like I said, I read reports from users where their N4 read the sim for days without an issue. Then it began to fail.

Hi,
I just purchased a P6800 to replace my current phone.
Everything is awesome about the device, but everytime I try to insert my SIM from my previous phone, it keeps saying "Please Insert SIM"
After many reboots, same message shows on the unlock screen.
I've tried other SIM cards from my friends' phones (H20, Red Pocket, T-Mobile, Etc.)
The only SIM it seems to detect is my old O2 SIM card from my travel overseas.
Are there different times of Mini SIMs? Perhaps the metal contact sizes are different for data and regular phone SIMs?
I hope someone can help as I would love to utilize the full capabilities of this device.
Thanks.

It uses a regular sized SIM, not a micro-SIM. Are you sure you're inserting the SIM with the contact side down notch end first?

Im having the exact same problem. Bought a Telstra sim for my P6800 and it wont recognise it. The same sim works fine in my Galaxy Nexus, and the sim from my Galaxy Nexus works fine in the Tab. It's just this particular sim/data plan it wont recognise the sim, keeps saying 'insert sim'. I had the sim replaced, same issue. Any ideas?
Did you try to go to Settings -> Wireless and then configure the APN, etc.?

Wont let me into it. When I press Mobile Networks it tells me to insert a sim. The sim works fine in other devices but is not detected by the Tab. A Google search reveals that it is a common problem with certain sims and carriers, I may have to go to a Telstra store and try a few different sims.. Unless there is something else I can try?
I had a problem with my sim card but when I reboot my device It is Ok.
Yes. Try to reboot your device. When I inserted my SIM while the tablet was on, it would give me the same error until I restarted the tablet.
You definitely have to reboot the Tab after inserting the Sim.

With respect, rebooting was the first thing I tried! Makes no difference whether I insert the sim when the Tab is off or not, still not detected
If a different Sim card works in the tablet you can see if your phone provider can give you another Sim. If no Sim works, it's most probably HW related

A sim that worked earlier in the week no longer works, sadly now looks to be a hardware issue..
You can't use the micro sims they mess up the sim reader if you leave it in it will continue to work but once you take it out it breaks the sim slot it happened to me i used a att sim first and it worked fine then a rep at a cell shop put his micro sim with an adapter into to it to see if it worked with t-mobile and when he took it out the sim slot wouldn't work I had to get the device replaced

And that is exactly what has happened to me. I was using a micro sim with adapter and after I removed it, the device no longer recognises sim cards. It will cost me AU$130 to have it repaired.
A big warning to everyone else not to use micro sims with adapters, make sure you use a full old-style sim card! Quite annoying since most carriers these days have the sim card with the micro-sim push out, these will damage the sim slot in the P6800
Same problem here after using a microsim adapter now it doesn't recognize any sim. Do you know how to remove back cover so i try to repair internal sim card reader?

Same problem here, after using a Micro-Sim Adapter, my p6800 stopped recognizing the sim cards. I hope the repair do not cost too much.
Don't know if this might help.
I had the same experience when I insert my Sim card the first time.
Luckily I have about twenty old Sim card to play with.
I tried most of them and found put that some Sim card is thinner.
So, what I did was to paste a layer of clear tape on the back of my Sim card to make it slightly thicker.
It will fell a but tight at first.
But it helps.

I've also tried that, pasted a piece of tap to make the sim a bit thicker but It didn't worked, I think I have to send it for repair.
Thanks for your help.

Last try would be the most ancient method.
Try using a eraser to rub the contacts of the Sim card.

Yesterday I upgraded to a gs3 which came with a micro sim. I wanted to see if I could keep my old phone as a backup. Would the lte micro sim work in my non-lte full-sized-sim captivate/gs1?
After 3 trys i managed to properly align the micro sim in the full sized sim slot and it worked. But then the weird part. Without powering down the phone I plucked out the sim (possible because the micro sim is so small). To my surprise the phone did not give any error and both data and voice calls continued to work without a sim actually in the phone.
How was that possible? Further, what would have happened if I had booted up my new phone with the sim card that my old phone still thought it was using (I was too afraid to try)? Would both phones continue to work? Would they both ring when someone calls?

any sim should work as long as its activated and its the same size.
and no they both wont work, the phone that has no sim will show "no sim" upon reboot

Perhaps I was not clear. I removed the sim without turning the phone off and it continued to work. I know it should not, but it does. That is what I am asking, how is that possible? Does the phone only check for a sim when it boots, and from then on the sim is not needed?
Then what would happen if I boot up phone #2 while phone #1 still thinks that the sim card is in it.
I'm interested, try it and let us know what happens.

I'm not an expert, but I think all the SIM provides is a string of numbers that identifies the phone with a phone number. This is most likely cached in the device while it is on and it might not need the SIM card after it has already gotten the information. This might not pertain to all phones, maybe the Galaxy S3 was programmed slightly differently.
If you power down the phone and restart without the SIM, the phone will most likely ask you for a SIM.
It is an S1/Captivate that is working without a sim. And yes, when I reboot the phone it stops working. I'm not brave enough to try both phones at the same time. That seems like something that the phone company would notice.
I tried removing the SIM from my captivate while it was running, and for a short time it still showed signal. Soon after I got a message asking to put in a SIM and restart. I don't have an LTE SIM or microSIM to test with, but it doesn't seem likely that the cappy will continue to work without one. Or at least without starting with a regular SIM.

i Know that this is an old thread but i just wanted to say that with some networks, you can take the sim out and still use the phone locally. they only use the sim for international or roaming outside the country. thats what i got from Sprint before. i dont know about other networks
Pease cany any body tell me who can download apps frpm this software

Hi everyone!
I am facing a very frustrating problem. I just got my Nexus 4 about 2 days ago. The problem is, that when I insert my MicroSIM card, the phone says NO SIM CARD.
Everything else on the phone works (I am able to find local GSM networks as well , so I don't think it's the GSM / UMTS modem). I have tried it with 4 different sim cards, but still nothing.
Can it be a software issue, or the sim card reader is corrupted? I don't know what to do.
Thanks for your replies in advance
I think you have a defective Sim Reader, get an RMA

Well, I managed to get it work. The SIM reader was defective, I sent to get it repaired and now it's working fine.

I have the prob
I have a solution
I had the same problem. My solution is: don't use the microsim tray. Just put in the sim and get a good cover. It works like a charm.
So to make a long story short, an old straight talk sim card works on my phone but some red pocket sim cards do not. I have tried many things to make the sim cards be recognized like turning the phone off and on, taking the sim card out and putting it back in. I'm wondering if anyone knows of some reason for a new sim card to not work. I just got 10 sims from ebay so I'm going through them hoping that one will work.

nope.
Yes. just in my phone and to only one sim card. When I put the sim in my friend's mobile the speed is normal.
possible reasons: Before some day I went to my village and the network reception there is very bad. I couldn't open any pages(pretty slow) .Now I am back to my previous place but the speed is same. I dont have 3G network here.
I have GT-S7562 rooted(dual sim). the problem is only with one sim card and only on my handset. I tried with new GPRS settings, rebooting, flight mode,network searching, interchanging simcards... not of any help. Its been 15 days since.
So what could have gone wrong? help
do u have a data limit?
What do you mean only one sim card? If you put another simcard (ex a friend's sim) does the phone work correctly?
If thats true then you should try getting a new sim card from your provider.
Keep in mind that your data speed has many limiting factors. (Ex. Service strength/ the cell phones actual capability /geographical location or region) but depending on your service provider, it's realitivaly cheap for a new SIM card in many cases. Last time I needed a new one it was $15...
