Is this a > PPP problem or more likely an issue with the u3g driver? I dont use mpd, only the built in ppp. Can you try it with the built in ppp ? Looking at your log snippets LCP: no reply to 1 echo request Does it ever respond to LCP Echo or LQR ? If not, try disabling that. You wont have link detection, but it might be some incompatibility with mpd. I use an older Sierra Wireless LTE modem on an APU and it works great with the built in tun/ppp combo. *pppgprs:  set device /dev/cuaU0.3  set server /var/run/gprs-internet "" 0177  set speed 921600  set timeout 0  set authname wapuser1  set authkey wap  set dial "ABORT BUSY TIMEOUT 2 \        \"\" \        AT OK-AT-OK \        AT+CFUN=1 OK-AT-OK \        AT+CMEE=2 OK-AT-OK \        AT+CSQ OK \        AT+CGDCONT=2,\\\"IP\\\",\\\"ltemobile.apn\\\" OK \        AT+CGACT?
