AT command to detect SIM supplier?

3 thoughts on “AT command to detect SIM supplier?

  1. I am using SIMs from different suppliers and have to hard code in the matching APN for each supplyer.

     

    Is there an AT command that I can use to query the SIM that is installed for some bit of information so I can automatically determint what APN to use to match the SIM?

     

    I hope that makes sense.

     

    Many thanks, Ben H
