N900 SIM Problem
 

Dear All

I want to share my problem with you, My device has a problem that it cant take any SIM any more also there is a red lable on SIM
There is a message when i turn on my device will appear on the screen that its not taking Data from SIM also if there is no card it will show this message again

when i make *#06# to check my IMEI it will show it blank.
also when i go to settings to my nokia icon will give me internal error and it will close

I tried to flash it but without use

Can any one help me with this

Many Thanks

The message that it shows

(All telephony functions, including emergency calls, are disabled due to a communication error. to recover, you might have to reboot the device.)

it seems no one is available :)

Re: N900 SIM Problem
 

Flashing didn't solved the problem?

I'm sorry to hear that (http://talk.maemo.org/showthread.php?t=66870)

Re: N900 SIM Problem
 

Yeah Flashing the phone didn't solve the problem i think the EEPROM has been effected

Re: N900 SIM Problem
 

did you try to downgrade to a lower PR?

Re: N900 SIM Problem
 

I had the exactly the same problem.
The warranty was still valid so I sent it for repair and they replaced it with a new one and I got a new 24 month warranty.
Before I sent it in I was able to get it to work for a short while with placing a bit of paper between the battery and the sim so there was a little pressure on the sim, but the problem became worse after a while.

Re: N900 SIM Problem
 

i did downgrade the level with same problem, i sent it to nokia in kuwait and they told me that its difficult to repair...!

the warranty is not valid anymore.

I ready dont know what to do with it.

Re: N900 SIM Problem
 

I'm not sure why downgrading was mentioned as an option.

This problem has come up many times, and nearly always the problem is hardware related. I've had it too, and eventually Nokia "care" replaced my N900.

Re: N900 SIM Problem
 

Nokia support didn't repair it and as they said (it's not fixable)
i don't know how no one from nokia care knows how to fix hardware problems for this model

So, This is the End of my Nokia N900 :)

Re: N900 SIM Problem
 

hi
can iask how come you get a hardware problem or it a software i m intrested coz i wanna install anroid is there any connection wth anroid ??

Re: N900 SIM Problem
 

I really don't know how It happen, one day it started to give me an error after that it stopped working.

I think most of this model N900 users will face the same problem because until now i saw many people are complaining about the same issue

Hope yours will be stable and i don't think that its because of installing some applications or another OS in it.
The nokia N900 hardware might be weak and cant stand forever

Re: N900 SIM Problem
 

thnx for reply its a bad news for nokia user and for nokia future i hope u find a sloution

Re: N900 SIM Problem
 

I have the same problem.

Because the problem can initially be delayed by putting pressure on the sim card slot I have a feeling it's a broken/loose connection on the mother board. There may be a hardware fix similar to the usb connector issues, but no one with sufficient soldering expertise has taken a good look at it as of yet.

On the other hand, I still use it as a wifi internet tablet while my telephony usage is through a simple candy bar phone that doesn't do much more than voice, sms and very limited email.

Re: N900 SIM Problem
 

am using my phone as yours only for WiFi connectivity
unfortunately no one from nokia support tried to fix it i don't know why, i think its something with the EEPROM because also the IMEI disappeared from the software means that something got wrong with it.

if you tried to flash the phone with COMBINED it will give failure at CMT means something wrong happens to the EEPROM.

Re: N900 SIM Problem
 

okay....after more than a month of research i came to the conclusion that n900 has a problem with the sim card slot. initial it starts as a hardware problem(sim card slot) and than it goes to be a soft error.
all this is because the sim card is moving...or the connections under the slot are bad, when the phone is on.this will trigger the soft error.
if this keeps happening, the error will not allow the recognition of the sim.
when my phone start having the problem, a reboot would fix it.
after a while it was harder and harder to recognize the sim.
eventually it was not recognizing the sim at all.
i got a different phone,but i didn't gave up on n900.
i took the board out, and with a heat gun, i heated around the sim slot, i erase the hole memory, and format it.
after that i had the pleasant surprise of my n900 recognizing the sim, after i month of no sim.
i try to create the problem back, so i can convince that is the slot the problem, and i put the n900 on a table and start pounding the table to create hard vibrations....and then boom...the n900 lost connection, and after i stopped , it came back.
so the problem it is still there with the slot.not as badly
i did put some rubber between the battery and the sim slot ,so it holds it in place good, even in case of hard vibrations.
this is week 2 after i fix my phone, and it performs good

Re: N900 SIM Problem
 

I have the same problem...
Problem became worse after time and paper-solution and now my case is broken too...

Phone works after pressing-cover+reboot..till I put it in my pocket
and move....


No soldering FIX yet?

I do not want to give uo my N900
:-(
