But before connect to internet I need to use
/usr/local/sbin/usb_modeswitch -c /usr/local/etc/usb_modeswitch.conf
/usr/local/etc/usb_modeswitch.conf
Code: 
DisableSwitching=1
EnableLogging=0
DefaultVendor=0x12d1

TargetProduct=0x1506

And after that it connects to the Internet using profile mts_x:
ppp.conf
Code: 
default:
   set log Phase Chat LCP IPCP CCP tun command
   ident user-ppp VERSION

   set device /dev/cuaU0.0

   set speed 115200
   set dial "ABORT BUSY ABORT NO\\sCARRIER TIMEOUT 5 \
   \"\" AT OK-AT-OK ATE1Q0 OK \\dATDT\\T TIMEOUT 40 CONNECT"
   set timeout 5                        # 3 minute idle timer (the default)
   enable dns                             # request DNS info (for resolv.conf)

mts_x:
 set device /dev/cuaU0.0
 set speed 460800

 set dial "\"\" \
     AT OK \
     AT OK \
     ATS0=0 OK \

     AT OK \
     AT+CGDCONT=1,\\\"IP\\\",\\\"internet.mts.ru\\\" OK \
     ATDT*99# CONNECT"

 set login
 set authname "mts"
 set authkey "mts"

 disable pap
 disable chap
 enable dns

 set ifaddr 10.0.0.1/0 10.0.0.2/0 255.255.255.0 0.0.0.0
 add default HISADDR
All works fine and it connects in 3G (or 4G) mode with a blue LED on the modem, but after some time (various, from five minutes to several hours) it switches to 2G mode with an orange LED and after that to reconnect on full speed I need do these actions:
  • /etc/rc.d/ppp stop
  • Physically remove modem from usb port
  • Plug-in modem to usb port
  • Run again usb_modeswitch
  • /etc/rc.d/ppp start
So my question is: can I somehow emulate physical removing of modem with usbconfig or other utilities? Or maybe there are available some ppp.conf options to deny the switch to 2G mode?
I'm trying various actions to do:
  • usbconfig -d 3.2 power_off to powering off modem
  • usbconfig -d 3.1 reset to reset usb hub
  • usbconfig -d 3.2 power_on to power on usb modem again
But after that the modem connects only in 2G mode, until I physically remove them.

Log when modem inserts in USB port:
