RUT955 and LTE bands selection

[gianmasi]

Hello,

Is it possible to set the LTE bands to be used with a RUT955 via sms?

Thanks
Gian

Hi, @gianmasi!

Changing LTE Bands via SMS, while requiring several steps, is indeed feasible. This can be accomplished by executing UCI commands through SMS messages using the SMS Utilities uci api rule. To enable this feature, navigate to Services → Mobile Utilities → SMS Utilities and enable the UCI API rule.

The SMS text should include the following parameters:
<password> uci set <config>.<section>[.<option>]=<value>

An example configuration is as follows:

123456 uci set simcard.@sim[0].band=manual
123456 uci set simcard.@sim[0].lte='lte_b3'
123456 uci add_list simcard.@sim[0].lte='lte_b5'
123456 uci add_list simcard.@sim[0].lte='lte_b28'

In the example above, the selected LTE bands are B3, B5, and B28, with WCDMA set to “none”. The uci add_list command line needs to be run for each band that you want to enable.

For easier verification of the configuration, you may refer to the WebUI under Network → Mobile → Connection, to check the band selection. Alternatively, if you SSH into the router, you can use the command cat /etc/config/simcard or uci show simcard to review the parameters.

Please remember to commit your configuration at the end.

Should you have any questions, please refer to the following guides:
