The default logic to decide which are the current capabilities parses outputs of several commands, including +GCAP. The "+CGSM" reply in +GCAP is used to say a device is "gsm-umts", although this doesn't seem to be right; a 4G-only 3GPP modem will also reply +CGSM. E.g.: $ mmcli -m 0 /org/freedesktop/ModemManager1/Modem/0 (device id '13d738ce72d62749f86308b7d620f063dd38bc47') ------------------------- Hardware | manufacturer: 'Telit' | model: 'LE866-SV1' | revision: '23.00.002 (M0A.00020)' | supported: 'gsm-umts, lte' | current: 'gsm-umts, lte' | equipment id: '352613070042357' Logs show how the AT+WS46? check does report 4G-only as supported *mode*, but still, we report 'gsm-umts' capability, which would apply only to 3GPP 2G/3G devices.
