Yes, it works. There are daily tests running automatic connections to T-Mobile and other major carriers in the USA and other countries. Are you sure the "fast.t-mobile.com" APN should be used? Maybe your new SIM cards require a different one like e.g. "wholesale"? What is the output of "mmcli -m a"? Also, try adding --timeout=300 to the --simple-connect call. -- Aleksander
