But... https://cgit.freedesktop.org/ModemManager/ModemManager/tree/src/mm-sms-part-cdma.c The issue here is that the message isn't formatted as 3GPP2/CDMA because the modem is actually an LTE modem (i.e. 3GPP). As soon as a modem is 3GPP, we use the 3GPP format, see: https://cgit.freedesktop.org/ModemManager/ModemManager/tree/src/mm-base-sms.c#n311 The question now would be, is this something that happens to all US-version Telit modems? Isn't this actually a bit weird, given that the LE866-SV1 is actually LTE-only (i.e. 3GPP-only, not 3GPP2)? -- Aleksander https://aleksander.es _______________________________________________ ModemManager-devel mailing list ModemManager-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/modemmanager-devel
