Hello,

My SIM card with CCID number 89883030000107945922.I am trying to register murata 1SC EVK to the Skylo network using free emnify Sim Card with only NTN service available. Below I want to show you my steps to register to the Skylo network:

• ATZ – to reboot the EVK -> I receive OK;
• AT+CIMI - to retrieve the IMSI number of the SIM Card -> Get the appropriate IMSI number of the SIM Card;
• AT%PDNSET=1,"em","IP" - to set APN to emnify-> I receive OK;
• AT%PDNSET? – query the current APN -> I receive %PDNSET: 1,em,IP,,,,,0,0,0;
• AT%RATACT="NBNTN" – switch to NTN -> I receive OK;
• AT%SETCFG="BAND","255" – switch to 255 band which Skylo usus in North America -> I receive OK;

• AT+COPS? – see registration status -> I receive OK;

• AT+COPS=? – list available networks and I receive +COPS: 0 so basically no networks available however I expected for 90198 which is the Skylo network.

• AT+CEREG=2 - to see if the SIM Card is actually registered to any of the network and isnted a get the routine below where I try to register and deny every time:  

  +CEREG: 2

  +CEREG: 3

  +CEREG: 2

  +CEREG: 3

  +CEREG: 2

  +CEREG: 3

• Can you please suggest me what I am doing wrong. I run Tera Term to do that.

Regards,

Igor
