High Tech Fix For "Nokia N900: All telephony functions are disabled" issue

Last week, my Nokia N900 phone suddenly popped up with the message -

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

You will see something like a sim card icon on the top panel when this message appears.

Awesome, it seems I couldn't make or receive call after this message is shown, I rebooted my phone and it works again ... until this week, the phone is dead, I can't use it as a phone but small tablet. Maybe I should try google to see if there's any solution and here's what I have found -



Basically the solution is to claim the warranty and Nokia replaces a new one for you, what if you are out of warranty, just someone like me? Nokia has no answer for that, thank you Nokia ;)

I was thinking "Sim card icon and communication error", maybe it is sim card slot issue? I don't know, but here's what I try -

0. Switch off N900
1. Open up N900 case at the back(battery part)
2. Take out battery
3. Take out sim card from the slot, clean it
4. Put the sim card back to the slot
5. Tighten the slot
6. Take the toilet paper, yes I say toilet paper because it was on my desk when I was trying to fix this
7. Try to tear the toilet paper and make it thicker by layering them
8. Make the toilet paper slightly same size(square) as the sim card slot
9. Put the toilet paper on top of the sim card slot and push in a bit
10. Put back your battery and press it little hard, the toilet paper will be underneath
11. Close the case
12. Switch on your phone

The phone works automagically, don't ask me why, it's really high tech fix if you ever encounter this issue.

Have fun with N900 again, by the way no fun since not much apps for it(Thank you Nokia), BUT it works as PHONE again!

Cheers ;]

p/s: By the way let me know if this solves your problem, I would like to hear about it!

i fixed at least half a dozen of cellphone this way, starting from old ericsonn "shark fin" to more recent smartphone. amazing to see that a piece of paper still fixes ultra modern piece of technology

After I started to have the same issue with my N900 last week I sent my phone to the local Nokia Care centre. First they told me they will fix it for around 30 US$ and I agreed. Next day they called and told me it will cost over 300 US$ which I declined and got the phone back flashed to an old Maemo version :-(
So I started to search and found your description here.
The paper trick first didn't work do I put a small piece of paper below the 6 contacts for the SIM card to push them up and now the phone works again without problem.

LOL.. I just read this post. I got similar problem not with the Sim Contact Point but the battery!! If i shake my damn N900 the contact point will lose and the phone shutdown and when u turn it on again u need to setup the Time/Date($##$).

After reading your post i quickly padded up the backside of the battery with some cottons and stick up together with a double side tape...

Works like a charm!! Now i can use the N900 happily even after zombie apocalypse!!

Did it with a tissue paper. Worked like a charm.Thanks a lot :)

Hey thanks my problem was solved but a new peoblem came. My phone looses the signal while talking and a icon of no sim card appears on signal bar and after 10-15 secs automatically signal comes back. Its very irritating when ur call gets disconnected when you are talking. Do u have any solution for this. Thanks in advance.

Hello Guys,
I found one more so called 'FIX' for the Comm error...
Little risky yet easy to perform/

Here it goes...
When you remove SIM card from its slot, there are 6 pins which connected your Phone to the SIM card.
You need to take a forceps or blade & lift them 6 pins on the Phone.

< MAKE SURE YOU DONT OUT MUCH FORCE ORELSE YOU MIGHT BREAK THEM. >

It is an alternative for the tissue paper method :p

Hi, thanks for that. I'm from Brazil and I found your post on the internet and through this simple solution could solve this problem. I would not want to get rid of n900, because I love this phone. You helped a lot, thanks.

Santosh said...

I tried the paper idea, but my phone kept losing signal at times. i then just raised the 6 contact points a wee bit using my fingers, working all fine till now!! my Nokia "care center" said there's no solution, I'd have to throw it away.
