Hi dear colleages,

I´m trying to change a  RUTX09 from 3G to 4G by commands, no GUI access, but so far with no luck, using this command:

 uci set simcard.@sim[0].service=lte

after that,

# uci show simcard.@sim[0].service

simcard.cfg01aa0e.service='lte'

But RUTX09 remains connected in 3G. So, can you explain me how to change a RUTX from 3G to 4G by commands?

BR

Thanks for contacting TELTONIKA | Crowd-support forum.

You did right, you have just to add Two commands:

''uci commit simcard''          >>> It writes changes of the given configuration file ‘simcard’

''/etc/init.d/simcard restart''   >>> It restarts a particular service ‘simcard’

Check the current config:

root@Teltonika-RUTX11:~#  uci show simcard

simcard.@sim[0]=sim

simcard.@sim[0].modem='3-1'

simcard.@sim[0].position='1'

simcard.@sim[0].primary='1'

simcard.@sim[0].auto_apn='1'

simcard.@sim[0].enable_sms_limit='0'

simcard.@sim[0].band='auto'

simcard.@sim[0].service='3g'

simcard.@sim[1]=sim

simcard.@sim[1].modem='3-1'

simcard.@sim[1].position='2'

simcard.@sim[1].auto_apn='1'

Switch Service mode from 3G to LTE:

root@Teltonika-RUTX11:~# uci set simcard.@sim[0].service='lte'

root@Teltonika-RUTX11:~# uci commit simcard

root@Teltonika-RUTX11:~# /etc/init.d/simcard restart

Check the config after the modification:

root@Teltonika-RUTX11:~#  uci show simcard

simcard.@sim[0]=sim

simcard.@sim[0].modem='3-1'

simcard.@sim[0].position='1'

simcard.@sim[0].primary='1'

simcard.@sim[0].auto_apn='1'

simcard.@sim[0].enable_sms_limit='0'

simcard.@sim[0].band='auto'

simcard.@sim[0].service='lte'

simcard.@sim[1]=sim

simcard.@sim[1].modem='3-1'

simcard.@sim[1].position='2'

simcard.@sim[1].auto_apn='1'

Excellent! it works. Just I would add a final RUT reboot, after that the green led has changed from 3G to 4G.
