Using a defferent SIM card

I’m thinking of buying “Raspberry Pi 4G/LTE Cellular Modem Kit”. This kit comes with Sixfab SIM card. Do I have an opportunity to use any other SIM cards (T-Mobile, AT&T etc.)? I’m just not planning to use my project out of my state so 1 career is going to be enough for me and it’s probably going to end up cheaper.
Sincerely, Max.

Hi @ShmyaksMaks ,

We are providing Sixfab Sim with the kit for Sixfab CORE solution. Sixfab CORE solution is not compatible with different sims.
While using a SIM other than the Sixfab SIM, you should follow the guides provided by module OEM for establishing the connection.
