Hi, I wonder if anyone used Ettus SDR (e.g., B210) for AT&T (or Verizon) 4G/5G network demo? For instance, sending and receiving a text message between B210 and Android mobile phone. To do this, B210 may need to be programmed with a SIM card info. I have a SIM card for AT&T device but I couldn't figure out how this can be set up with B210 and OpenAirInterface. Would this configuration require some information available under a non-disclosure agreement with a cellular carrier vendor?
I wonder what are the key information and procedures for connecting Ettus SDR (programmed with OpenAirInterface) to a commercial cellular network. If you did a similar demo or know a related open source project (either with OpenAirInterface or with Open5GS), any pointers would be greatly appreciated. Thanks SC
