Hi @Herzen,
Glad to hear that it helped!
We will consider adding this toggle to our WebUI, but the operator also should not disconnect the device if it requests IMS, but no IMS is available on the operator side.
The issue with fully disabling IMS is that if no 2G/3G networks are available, the router will no longer be able to accept/make calls and in some cases even SMS might not work.
Just one more note - my suggested command will not survive a firmware update. One way to overcome this is to execute the following commands to add disable_ims to the configuration file:
uci set simcard.@sim[0].disable_ims=1
uci commit simcard
/etc/init.d/network restart
Then you can check IMS status with this command:
root@RUTM30:~# ubus call gsm.modem0 get_ims_state
{
"mode_id": 3,
"mode": "disabled"
}
Best regards,
