Environment

  • Onomondo app: Network Logs

  • SIM type: applicable to all

Issue

  • I see sms_disabled error in Network Logs

  • I’m getting an sms_disabled error when trying to send SMS to a SIM.

Solution

Enable SMS on the SIM in the Onomondo app.

  1. Go to the individual SIM page.

  2. Click "Edit SIM".

  3. Enable SMS under "Device information".

  4. Click "Save changes".

Once enabled, SMS functionality and GSM connectivity will be restored for that SIM.

Cause

Disabling SMS on a SIM leads to failed GSM registrations because, in the Onomondo backend, GSM access is linked to SMS functionality.

Even if the device does not actively use SMS, SMS must be enabled for the SIM to connect over GSM. If SMS is disabled, the SIM cannot register on the circuit-switched side of the network (GSM), which results in the device being unable to attach to GSM networks and remaining offline .

This means that disabling SMS blocks both outgoing and incoming SMS, as well as GSM network registrations. To restore GSM connectivity, SMS must be enabled in the Onomondo app for the affected SIM.
