My N900 doesn't recognize SIM card
 

Hello everyone

I installed a lot of apps from the extras repository and etc... and yesterday my N900 crashed.. was like.. dead! It was unable to use.

I decided to flash it as explained in wiki page . Everything went ok, the N900 was back. But when i put the SIM card on it, it broke my heart :( The problem is Nokia doesn't detect the SIM card after flashing it... I already tryed diferent SIM cards and notting.
All the other software is fine, but i can't do any calls or send messages because no SIM detected.
It should ask for the PIN number to access the SIM card when i turn the phone on, but after flash it doesn't happen.

Can anybody help me?

btw... I flashed the phone without the SIM card in it.. you think it can be related?
should I flash the mobile again?

thnx

The same thing happened to me the 1st time I flashed. All you need to do is update your device ( I used the app manager while on wifi ) and after a couple updates, it should be working like it used to.

Please provide the SIM status by opening the X Terminal and entering:

dbus-send --system --print-reply --dest=com.nokia.phone.SIM /com/nokia/phone/SIM Phone.Sim.get_sim_status

And please provide the Network registration status by opening the X Terminal and entering:

dbus-send --system --print-reply --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.get_registration_status

did you flash to an earlier version than was on the phone already? you may have to update to the same or newer than you had previously for it to work.

I updated all the software, and now it works fine =)

thnx a lot for the attention ;)

and sry for the late answer.. i had some internet problems.

btw... Maemo rules!

I suddenly last week also got this error.
"SIM card registration failed" when N900 boots up.
Still running PR1.2

Before my phone and the SIM card was working fine for 3 months.

SIM-card is not registered. If I manually search GSM networks (it will find 3 where 1 is the one I should get into), and try to connect any of the found networks, it always says "No access".

However, the same SIM card in N95 works without problems.

I even changed to new SIM card from my operator, but same thing, does not allow GSM access in N900, but does in N95.

When I last week tried with a SIM card of my friend, which has a different operator, my N900 worked fine.

Operator's technical help desk couldn't find a problem.

Haven't yet tried the dbus commands Andre Klapper mentioned but I got the system log which has some lines which may explain what is happening:

Maybe the problem goes away when I upgrade to PR1.3, but haven't done that test yet as it would be nice to know what is the problem here. [Edit: The problem didn't go away by flashing both rootfs and eMMC with PR1.3 images.]

Re: My N900 doesn't recognize SIM card
 

The above dbus-commands returned this:

# dbus-send --system --print-reply --dest=com.nokia.phone.SIM /com/nokia/phone/SIM Phone.Sim.get_sim_status
# dbus-send --system --print-reply --dest=com.nokia.phone.net /com/nokia/phone/net Phone.Net.get_registration_status
(Edit: got the meanings of some of the fields from an another discussion thread, and from here.)

Still no cellular access, although radio seems to be working because it finds networks.

Here is a fresh reboot syslog, system messages from csd and ssc are selected:
In 17:30:26 I try to call the phone answering service.
In 17:32:39 I try manually to search networks, I find 3, and select the one which is my operator -> "no access".

But still no problem with the same SIM card in Nokia N95.

Any ideas what could be wrong?

Re: My N900 doesn't recognize SIM card
 

Well, rootfs and eMMC flashed, but the problem still exists.

However, flashing rootfs and eMMC does not entirely clean the device, because when it booted, it asked the security code which I have set to be asked always when the device boots up. The security code was not reset to 12345, but was my old one.

So something still is not reset to factory defaults when rootfs and eMMC are flashed?

I guess I try every trick until either I get the phone bricked or get it to work. Maybe flashing Meego next, just for curiousity.

In this thread quite a few folks have reported success after adding a piece of paper in the SIM holder!
