I read about sim card types since it must be a sim card problem
but I didn’t find anything useful.

<div>I tried two sim cards one that works fine and
another one that doesn’t get paged, I noticed that
during the location update procedure everything is
exactly the same (using wireshark). The log files are
also similar. Although both cards work fine if used in
a normal phone (even with a motorola c123/118 …).</div>
<div><br>
</div>
<div>A<span>nother thing to mention is that some sim
cards only work when i stick them on a BTS that has
the "SI type 3, GPRS indicator" as follows:</span></div>
<div>
<div>
<pre> "3G Early Classmark Sending Restriction: Neither UTRAN, CDMA2000 nor GERAN IU MODE CLASSMARK CHANGE message shall be sent with the Early classmark sending" </pre>
<pre> while they can only make calls without being able to receive anything on other BTS where <span>the "SI type 3, GPRS indicator" is as follows:</span> </pre>
<pre> <span>"</span>3G Early Classmark Sending Restriction: The sending of UTRAN,CDMA2000 and GERAN IU MODE CLASSMARK CHANGE messages are controlled by the Early Classmark Sending Control parameter<span>"</span> </pre>
</div>
<div>I would be very grateful if anyone has some
explanations to what is going on.</div>

I think it would help us out a lot if you could
provide at least one complete log file from the
output of the mobile app, so we can start having
some ideas.<br>
<br>

Hi,<br>
I would first like to thank all those who
participated in this nice project. <br>
I recently started working with osmocombb and
was able to have it working fine on a motorola
c118.<br>
However, I noticed that some sim cards can
connect normally to the BTS, can make calls and
send SMS but can’t receive anything. They simply
don't get paged. While for some other sim cards
everything seems to be working fine.<br>
<br>
Does anyone know what might be causing this
issue ?<br>
<br>
thanks,<br>
Robert<br>
