Nokia :: N900 - No Mobile Network Connectivity / SIM Card Not Recognized
May 20, 2010
I got my N900 monday together with a new O2 sim card. It worked fine on monday and tuesday, but since yesterday, the connectivity to the O2 network is down. When I start up the phone, it asks for the PIN; so it seems that the sim card is recognized. But it does not connect to the network! The provider name does not appear next to the status bar, and there is no connectivity indicator on the status bar. Offline mode is disabled, of course.
Text messages cannot be send; when I try to call someone, I get an error (translated from german: "network not available" or similar). The strange thing is that sometimes I can reach the network for very short time. I then get missed test messages, but that's it. The connection lasts for not more than 2-3 minutes, I guess. I tried another sim card, and this one did not work, too. The sim card was placed properly into the slot. Is there anything I can do, or may this be a well-known firmware bug?

I just got my N900 about 2 days back, my sister dropped it and it would not turned on. I flashed it, and now it turns on but it does not recognize my internal memory card. I don't have an external card. I can't use camera, all websites show blank, and I get low error messages on almost everything else due to this.
If I go to settings/memory the the device memory is full and available memory for installable applications is at 80 MB. There is no corrupt memory card message. Also if I go to backup utility I get a "no memory card inserted" message. Any suggestions?

The title pretty much sums up my problem. I used the instructions from here to re-flash my N900.
http://wiki.maemo.org/Updating_the_firmware#Windows
And now as the N900 starts (takes a really long time) it does not ask for the SIM-card PIN code and as it is started it just shows a SIM-card icon with a red line over it near the battery icon. SIM-card is fine as it works on my N95. Any ideas what's wrong? I also tried another SIM-card. Nothing. And PC-Suite is not recognizing the phone either. I even tried flashing the eMMC but it didn't make any difference. The small lights in the bottom of the screen just blink for about 45 seconds and then after the boot video the phone start as if no SIM-card is there.

After new update, my phone doesn't seem to have a mobile network. I tried calling at&t we did some troubleshooting, they recommended a back up and restore to undo any updates but that didn't work. I have a galaxy s5... I can't go on the Internet or social media unless on WiFi. If I receive picture messages it won't let me download them/view them even on wifi....

After connecting my N900 to PC the phone is not recognized by the PC. I used new micro USB cable bought on Ebay when this problem occured (I doubt it is a coincidence). Before, with original cable, it worked OK, now it's not working at all.
When conecting the phone Windows alerts with:
"USB device not Recognized. One of the USB devices attached to this computer has malfunctioned and windows does not recognize it". The phone detects cable being pluged in and offers if I want mass storage or PC Suite mode, but it doesn't matter which one I choose. It also stopped charging from PC.

I am updating my N900 using Nokia Software Updater. It stops at a certain point (at 6.3MB) and then shows error message of slow connectivity.
Inspite of good connectivity, When I try again it resumes from 6.3MB and immediately throws the error. I tried reinstalling NSU but didn't help.Is there any way to clear cache of NSU?

I bought an N900 from the Nokia shop about 3 months ago. I'll be going away to (very) foreign parts next month, so I'd like to use the N900 as a tethered modem for my netbook. However when I connect the phone to the netbook via the USB cable, and choose the "PC suite" option, the phone is recognised when I use lsusb in a terminal, but the modem *is not*. Is there something in the phone settings I need to tweak, or an extra app I need to install in the phone, or is it a more fundamental flaw? Google searches for "Nokia N900" + modem + linux give pages which suggest that it should "just work", but it doesn't
If all else fails, I may have to fall back to using my previous phone (a Sony Ericsson v630i), which I *have* used successfully as a tethered modem, but I'd prefer to keep using the N900...

I've been deciding lately on whether or not I want to make the final push to the N900, but can't fully decide.I've been looking particularly for phones that are able to run on the T-Mobile's USA 3G network, 1700, yet at the same time have a slide out qwerty keyboard. After months of deciding and debating, I still can't fully decide on where I'd like to be exactly as I've gotten so many mixed reviews from both sides, in terms of user experience.
For example, some of the flaws I hear for the N900 are - it's mainly built as an internet tablet, not a phone, so don't expect to be able to rely on it fully. I don't know how stable the N900 is as of right now, but I'm hoping to hear good things about it. Part of the biggest gripe to which I have with my current phone, is that being touch screen only, it locks up or lags occasionally when I want to make a phone call or send a text message - and that's something I'm hoping dearly, dearly to avoid when I purchase a new phone. As for apps and things similar, I don't expect much and I don't need much as well. Having used an Android/Apple phone in the past, I didn't find myself downloading apps constantly. Instead, I found myself deleting them more, being content with the few that I had.
Another thing that I've heard about the N900 is that there is no portrait mode, yet from everyone that I've talked to, they've said that it's most likely something that's going to be on the way. That's something that I'm a bit curious to as well, since I have not gotten any real, definitive answers that can firmly state that this is true. Everything that I've heard so far only sounds like it's the conclusion of the typical rumor and speculation.
To sum it all up, by purchasing the N900 I'm hoping to experience a stable OS, which means stable phone capabilities along with internet browsing. I've been eyeing the Nexus One for quite a while now considering it's 1GHz Snapdragon processor, but the issues with the bottom screen buttons and lack of physical keypads have kept me on the edge. I do understand that Nokia also has a new phone coming out sometime soon which is suppose to redesign the way Symbian is, so my options are open. What I'd like to know from you N900 users, however, is do you think the N900 lives up to the standards? Or should I just wait and look elsewhere?
For those that believe that I should be looking for a "real" phone instead; my current phone that runs Android was designed to do so, yet I find myself browsing the web, etc., more than I do making phone calls. I'd like to elaborate more within this area, but forgive me as it's late right now and the detail are slipping my mind. I'd be more than happy to provide more tomorrow morning.
i appreciate all the time and honest feedback you contribute to this, and forgive me if I sound a bit demanding or others as it is 4AM where I am now, and I am trying to put all my thoughts down, straight to the point. I am choosing to write this now because I am in dire need of a new phone soon, since the one that I have right now is purely and currently unreliable in terms of making phone calls performance wise (lag, long delays, etc.) .Anything else you would like to add in terms of what you think may help benefit me in a decision will also be gladly appreciated.

I just acquired my N900 two days ago from a Nokia authorised dealer in Nigeria and even convinced a colleague to pick one yesterday as well.I live in Nigeria and my GSM operator is etisalat, im presently experiencing difficulties with using service commands on my phone. For instance, when i dial *235(hash, sorry cant find the symbol on my macbook pro) to check my balance; i get an error message saying "number incorrect". Other service commands dont also work. Is there a way around this?
Its frustrating also that there is no official Nokia plugin for isync. I use a macbook pro and cant seem to find a way around syncing both devices. In the interim, I found www.salling.com very useful in transferring my media files.

I have a US TMO 5230, got a "Generic" 32gb MicroSDHC for it. Looks like an Adata or Kingston except for the lack of logo.When I installed it out of the package the phone said the card was corrupted, so I reformatted on PC.Took it out of PC, put it in the phone, phone said the card was unformatted, and gave me the option of formatting it.Ran the phone's formatting option , and the card is not recognized on the phone or the PC.when installed in the phone and I go to "memory" in the filemanager, the cardslot shows as empty, no card in place. when I put the card into the slot on my notebook, it doesn't even recognize the mSDcard.does this mean the card is defective.

Out of the blue my phone is not connetcting to my office wifi. It keeps showing that the network is out of range even when my ipod and all of my colleagues are able to get a clear and strong connection. I had updated my phone to ICS a few days back. Could it be because of this?

Although the network bar shows full connectivity. My SE Xperia Neo V notification bar says no service due to which I'm not able to make/receive calls. My phone had fallen in water so got it repaired by authorized service center. They changed all the parts but still I'm getting this problem.

Ever since getting my sg2, I have always had a problem with the 3g. My phone when it connects proceeds only to upload, showing only the green arrow pointing up. This happens randomly, and it happens across all the different platforms of network connection the sg2 has. The issue is incredibly annoying as my phone can't download data, meaning I cant access the internet. The issue when it happens does seem to correct itself after sometime and with me fiddling around with it, but I am yet to find a permanent solution to fix the problem. My friend recommended I turn of data and turn it back on, which does work but is very hit and miss, and the issue can still very much be present when I turn data back on. The only solution which seems to work 100% of the time is turning the phone off and on again, however this is pointlessly annoying and quite a nuisance.

I had a problem when I added an Exchange Mailbox on a Nokia N8 and I had to take off the Device PIN lock from Exchange Access Clients and it automaticaly restarted the phone followed by a factory reset. When it was done, the phone lost all its contacts, messages and music. Than I have discovered the MicroSDHC Class 4 Card 8Gb was not been recognized in Windows and tried also on Linux with no success. Is there anyway to recover back the important information from the MicroSD card?

Here is the poblem I have since yesterday. If I put my friend's Sim Card in my N900, everything works fine. If I put my own Sim Card into my friend's phone, everything also works fine. If I put my own sim card into my N900, and try to make call immediate after the screen boots up (icons are slow then, still loading), then it also works fine.
However if my N900 properly boots up, then I cannot make calls at all. Setting it to offline mode then normal mode will not register with my network and result in Sim Card registration error if I wait long enough. So it seems like my N900 won't take my Sim Card after booting. it will take it during booting, but some process killed it. Can someone help me solve this? I do not remember installing anything since last time it worked.

Yesterday evening, I suddenly couldn't get a GPRS or any other phone signal on my phone. On switching off/on, I was informed of the above error message.I tried rebooting the phone via the 'u' key (battery out) process and this did not solve the problem. I tried the SIM card in my old phone and it worked perfectly.The N900 WLAN works normally.I did nothing unusual with the phone yesterday evening so I am bemused at this error suddenly happening.
