Hi,
I have recently purchased a SIM card. When I use the SIM in Nokia 3310, and
try to manually select a particular cell, it says no access. SIM belongs to
the same network.
If I insert the same SIM in Blackberry Bold 9780, I am able to manually
select the same network and even make phone calls. I have set the Network
selection mode in Blackberry to Manual. I have also asked it connect only
to 2G networks.
To debug the issue, I connected the Nokia 3310 to my laptop and observed
the messages it exchanged with the network. From the messages, I see that
Nokia 3310 is getting a TIMSI assigned from the same cell.
But my Nokia 3310 says, No Access.
I also see a "DTAP Radio Resources Management Message Type: Channel Release
(0x0d)" message from the Network to the phone.
What does the above message mean ?
Is there any way for me to further debug the issue ?
Thanks and Regards,
RM

Looks like your 3310 has a network lock. Are you sure that your phone is
unlocked? You can test it with 2 different SIM cards for real networks
and confirm that it is OK. DCT3 phones can be easily unlocked via IMEI.

Hi,
The phone is not locked to any network. Its an unlocked phone. I have
confirmed that.

Hello,
In this case it can be some hardware issue with your phone.
If your phone was pre 4.24 software version and it was upgraded it is
possible to have a corrupted EEPROM and you need to use some software
tools to repair it.
If that is not the case you can try to identify what hardware component
is broken by manually pickup a 900 or 1800 operator and check it if it
works. If one is working and one not this means your duplexer has issues
and needs to be replaced. Other components that might have issues are
the PA and COBBA ICs. Considering that a 3310 you can get for free now
it's not worth it to repair it.
Regards,
R.

Hi,
Thanks for your assistance.
So far from my analysis, this is what I have got:
After the BTS sends Location Update Accept message to the MS, the MS
responds with a MM status message saying
"Invalid Mandatory Information".
In a working case, the MS should respond with a TMSI Reallocation Complete
message which is not happening.

Hello,
3GPP 24.008 subclause 8.5 has an explanation for that message.
Sorry but I don't have any other ideas what can be wrong with your Nokia
3310.

From here, I don't know how to proceed further.
