Question

Is it possible to switch sim using UCI?

Comments

Peasant,

thanks! Where may I find the list of supported procedures?

Greetings,

Yes, you can switch to another sim by following these commands. 

uci set simcard.@sim[0].primary=1

uci set simcard.@sim[1].primary=0

uci commit simcard

luci-reload

/etc/init.d/simcard restart

I hope this helps.

Well, this is to change default SIM. But I thought there's an API to execute `switch_sim` though

Hi again,

sim_switch is automatic service that lets you switch between sim cards on special actions. It won't help you in manually switching sim card through uci. As you see, the router will always seek its primary/default sim, and only if it's inactive it will switch to secondary, that is why it's easier to set secondary sim as default sim and see it as a "switch".

ErnestasB, If I send SMS with `switch_sim` it changes operator/network and stays on it until I switch it back or network connection is failing. For my use case, it is nice to switch it like that because of traffic shaping after 3 Gigabytes limit. There is no such condition in RUTX11 to switch sim by speed limit so I'm thinking of writing a script for that...

Is UCI necessary for your solution or I can offer you another way around with SSH?

---

SSH is fine as I was using it anyway:

$ ssh root@192.168.1.1 uci get wireless.@wifi-iface[0].ssid

RUT_88D7_2G

Would you provide me an example?

As you're already using SMS utilities to switch sim cards, I can offer you this solution

gsmctl -S -s "YourRouterPhoneNumber admin01 switch_sim"

instead of YourRouterPhoneNumber insert your sim card phone number with country code starting like 00366xxxxx or for example 003706xxxxxx, then instead of admin01 use your own admin password that you use on the router. 

This command will send SMS from your active sim card in the router back to itself and will switch sim cards. Just keep in mind, that after a switch, if you want to switch back, you will have to use your other sim card phone number to send and receive SMS.

Thanks, but if I can SSH the device I see no reason of using SMS - there should be an API... Is there any other way of doing it?

Hello,

Take a look at this page: https://wiki.teltonika-networks.com/view/RUT955_Monitoring_via_JSON-RPC_windows

Guide is for RUT955, but it is also applicable to RUTx11, just use username: admin instead of root when generating a token.
