Nokia :: N900 Keeps Losing Signal And Says To Insert Sim Card
Jun 29, 2010
For starters i love this handst but getting very annoyed by this fault I keep on having.Pretty much i am on my 3rd N900 as my last two kept on telling me to insert a sim card when there was one in there which worked with other phones and other sim cards did the same thing in the phone. Also it is always loosing the signal.usually a quick reset fixes this problem but now this phone won't pick it up at all. It has had no signal for 24 hours. Sim works in other phones and other simcards have the same problem in this phone.
I have changed from dual to gsm and 3g but still no luck. Carphonewarehouse says it is a antenee problem but this has happened to 3 of them!! Any ideas, as i am looking to swap it for the Nexus One which i don't really want to do but will be forced to if none of you have a fix.

I've got a N97 mini and notice that I keep losing the signal. I can be sat there, the phone won't move and yet I'll go from 4 bars to virtually one/none at all. I had a similar problem with another N series and apparently it was to do with the internal antenna.......I'm sure its not the network as was on 3 before changing over to O2 and had same issues ! Also does anyone know if the CR 116 will fit the mini as well ?

So far just 4 keys have shown this problem, including the space bar.The bad news is that when the black paint starts to goes, the white plastic underneath is illuminated from below and the keys are difficult to read. I think it may be that the keyboard paint was damaged by some suntan cream when I was abroad.(I have heard of sun cream doing this to the paint in car interiors.)
Does anyone know if the keyboard is user-replaceable without a lot of brain surgery on the phone?Is a workshop manual available online? Is the keyboard a cheap part?

i am at my wits end.I constantly get the message on my n95 8gb to 'insert sim card' this happens 10-20 times aday.The only way to resolve it is to remove the battery 10-20 times aday! There seems to be no reason for this as it can happen if left on a desk,in my pocket etc.I'm also getting the 'sim card registration failed' message now and then as well. IS THIS A SIM CARD OR A PHONE PROBLEM? Any guidence would be gratefully recieved.

I have an E71, and about once a day I get this message saying "insert SIM card." This hasnt happened ever not until just maybe a week or 2 ago. It happens almost daily and I have to restart the phone. Any ideas on why this might be happening and how to make it go away would be extremely helpful!

Since updating to 410.21.010, my E71 occasionally shows a "Insert SIM card" message. This is rather odd, as it's not feasible to do so (the battery blocks the slot), and the SIM hasn't had any trouble before. Worse still, when this occurs the phone becomes entirely useless - not only can I not access running apps (and the model doesn't require a SIM for that), I can't even turn it off.Upon removal of the battery to forcibly restart the phone, it starts just fine, SIM and all - so the card isn't poorly seated or anything like that.

I'm having 3 issues with my recently bought cell-phone(Nokia 5230).
First of all, I've bought a 16GB memory card, but I don't know how to remove the 2GB one it currently has inserted. I press down the memory card but it won't (Fully) come out! Can someone explain me how to remove it, please?
Another issue is with some Bluetooth connections.
I tried to transfer some songs from my girlfriend's cell-phone, I've connected the 2 devices by creating an authorized(Automatically transfers data between the 2 cell-phones) paired connection. But I can't transfer data from her cell-phone to mine. They connect but the data isn't transferred! Side note: I've been able to transfer data before with the same devices, it would only transfer whenever it wanted, though. If it failed, I had to change the permissions and just try again. It could fail countless times(Once it failed like... 15 times in a row).
Now, it just won't transfer. They connect and the "Receiving data via Bluetooth" screen appears, but nothing happens until the connection times out. I've done nothing wrong and everything is fine, I guess. Does it only happen to me?
My last (main) problem:Battery.
My battery has a very short duration time. At the first time I turned it on, I've used it until the battery ran out, like I was told so. Then, I've plugged it to the switch and turned it on. I've used it through that time though, only to send and receive text messages. I exchange about 400 text messages per day. I've done everything I could to save battery. I've turned off the delivery reports, I always have it in silent mode, the screen bright is lower than the default value, etc. Still, it only lasts me like 20 hours before it ran's out. The first bar takes "a lot" of time to disappear, but the last 6 ones disappear quite fast.
I've tried to let him charge for 10-12 hours 2 times after that, but I didn't notice any change.If I'm on a long duration call, the battery runs out after... 3.45-4.30 hours. But that's definitely not the problem.I don't know if this affects, but it is always connected to my operator through 3G.

I have Nokia 5230 it has Symbian 9.4, 5th Edition.I am having some strange problem with my mobile, don't know what to do.So here is my problem :-
When i insert Tata Docomo Sim Card in my 5230, and whenever i try to call any one it says Connection Error and am not able to call anyone, nor able to receive any, although the network signal is full.
When i removed Docomo simcard, and inserted Reliance in 5230, than it works fine and i am able to send & receive calls.When i put that Same Docomo simcard in Motorola, than it also works fine.Why does Docomo simcard shows Connection Error in Nokia and works fine in Motorola??

I've had an iPhone 3GS on Orange since April 2010, and am waiting to upgrade until the 5 (or whatever they call it) comes out later this year. I've always had a full 3G signal in my house since I have had my iPhone. Around 3 weeks ago, I suddenly noticed one evening that I had no signal, I put it down to a local reception problem or something and ignored it. Later that evening though, I realised that my wife, who has a Blackberry Curve also on Orange, still had a full signal. I also have an iPad 2 3G on Orange, which had full signal still, and then my brother came round with his iPhone 4 on Orange and again had full signal.
The next day I was driving to work and suddenly my signal reappeared, pinging in half a dozen texts and missed call alerts etc. Then when I arrived at work (where I usually get 2-3 bars of signal) again my phone showed No Signal. One of my colleagues has an iPhone 4 on Orange, and sitting on the table right next to my phone was getting 3 bars of 3g signal, where I had nothing. Walking around the town on my lunch break I managed to get 1 bar up and get a text in.
Over the last few weeks this pattern has repeated. I can still go to some places where I can get a full 3g signal. Sometimes I'm driving and the signal comes in for a while then goes. Sometimes I go to larger towns and get a full signal easily. However mostly for the last 3 weeks I'm getting no signal. When at home, if I go out of my house.
I have tried a normal restore, a reset and a DFU reset. Funnily enough these all seem to make it suddenly work again at home for about half an hour, then it disappears again. I've read about some people having a problem with jailbroken phones, but this phone never has been. I'm guessing there could be something wrong with the internal ariel, but it puzzles me why it still sometimes picks up a signal. Is there a signal amplifier in the phone that could have gone wrong and it's making it harder to find the signal?

I have a S5 SM-G900F and since the last update 5.0 my phone keeps forgetting its a phone.When I try to make a call I am told that there is no service also I can not receive calls and the is no phone signal indicator at the top. If I restart my phone the signal indicator reappears and I can make a call with out a problem. Then at some point it will lose the signal indicator again and I can not receive calls or send them.After the phone has been restarted I get flooded with all the texts or missed calls I have had, one of these was an important call from my doctor

I have a iPhone 3GS, and have had no problems with it whatsoever. However, recently whenever I am using an ap that is sending/receiving data (either through Wifi or 3G connection) my signal drops out every minute or so for several seconds, before searching and reconnecting, and resets my Wifi connection also. However, when simply texting or talking on the phone this doesnt occur. The problem seemed to have begun after installing iOS5, but since updating to iOS5.1, it still remains the same.
I have tried all the basics of reinserting my sim, restarting the unit, as well as trying a soft reset etc. It seems odd that the problem only primarily occurs with 3rd party aps, such as banking, chat and social networking including facebook.

My iphone 4 on 3uk network keeps losing 3g signal for no reason and its driving me mad. Switching it on and off restores signal for a while but it looses it again.

I bought a factory unlocked IPhone 4s (Model MD234LL and Serial DNPGYCCWDT9Y) from US and after the software upgrade 5.1.1 (9B206) I find that the device looses signal strength and does not connect to Internet 3G or on other occasions Internet connections drops. Sometimes I have "No service" that also comes up. Even making phone calls is difficult and during calls the conversation is dropped and i have to call back sometimes. I also use a BlackBerry and have a connection from same service provider but my BlackBerry shows better Internet browsing capabilities than the iPhone. When the iPhone shows no service my BlackBerry has signal strength.

if this is a 'feature' or a fault. I find that if my phone loses signal (i.e. going through a train tunnel) then it does not automatically reconnect once back out in the open air. I didn't realise this and wondered why I was not getting email feed on my phone. I pressed the top button to activate the screen and it briefly showed no signal before quickly registering full signal and then downloading about 15 emails. It seems that I have to wake the phone up after signal loss or else it will just sit there doing nothing. With the best will in the world this is going to be difficult - it is possible to lose signal fairly briefly and not even realise in which case the phone could sit unconnected for hours before I noticed all was not as it should be. Does anyone else experience this? I have had HTC phones in the past (a Desire HD just prior to this One S) and have never come across the issue before - my phones have always instantly reconnected as soon as a signal becomes available

Perhaps its a coincidence but I recently updated my iPhone to 3.1.3 and now that I'm in the office, I'm losing 3G access. I've always had a weak 3G signal in some parts of my office but it seems pretty consistent that if I put my iPhone in my pocket and then later go to use it. I'll not have 3G but rather edge.Anyone else every hear of this issue - losing 3G connectivity suddenly when it was not a problem before?
Is it related to the patch? I tried searching both here and google and I've not come up with anything that indicates this.

I've recently noticed that my xoom is losing connection to the web. In the lower right it says that I have a 3g signal, but none of the apps or browser can connect.After a manual reboot it seems to work again. I never saw this before sending it in for the 4g upgrade. Also this seems to be happening a couple times a day

The last couple of times I have used my GPS the phone frequently loses it's GPS signal. The phone is placed near the gear shift on the center console.
I saw a thread on Slickdeals that stated Google was replacing broken phones with re-furbished phones is purchased through the Play store. In the thread several people stated that there were GPS problems with the 1 batch of phones.

So I recently got my Nexus 5, switched as an avid Blackberry user (of the last 12 years, and 6 devices!) So far I LOVE the Nexus 5, and Android OS I think I should have been made the switch earlier. As soon as I got my phone and activated with my existing T-Mobile SIM, everything was working fine, except the Mobile DATA Network wouldn't work (only would work via wi-fi.) I called T-MO Tech Support 3-4 times, and after doing a factory reset, everything was back to working GREAT!
Now, 1 week later the Data Network stopped working AGAIN (I can make and receive calls, and text messages, however no Internet via Mobile Network.) I didn't change any settings or anything.. Again, I called t-mobile and they tried EVERYTHING (reset APN Settings, checked APN, Protocol, etc..) The last thing they asked me to do again was a factory reset, and once again everything seems to be working fine.
My question is: Why it keeps occurring? I don't use very many apps (FB, IG, WhatsApp, Weather, &Twitter only.) T-Mo was suggesting it could be an app causing this issue but I doubt it.
