I meant that it is not a problem of sim.
The sim works correctly in other slots or mobile phones.

Hi, you can try use the auto-imei tools to change the imei of those ports. You can enable this tool by this url:http://your-ip-addr/cgi-bin/php/gsm-autoimei.php
If this still don't help you can add my skype:[email protected] and prepare Teamviewer for me.
