EMnify’s Mobile Core Network has been designed to manage the network selection from the network side in conjunction with the settings on the SIM: it has a global view on the available radio networks, their supported features and live network status, temporarily or permanently steering the SIMs away from ‘low signal quality’ networks to the best performing ones (with the strongest signal).
The manual operator switching can be done in three ways:
- Selecting the preferred operator in the device's menu
- Via the API
- By blacklisting other operators in the EUI
On the Endpoints panel, after clicking on one of the endpoints, you can find the "Operator Blacklist" tab, which allows you to manage blacklisted operators with a simple menu, giving you the possibility to exclude MNOs from the standard coverage list.
To blacklist the operator, click “Add Operator” button in the top right corner of the tab, select the operator from the drop-down list and click “Blacklist Operator” button:
Blacklist all operators available at your SIM's location except for the one you need and reboot the device if needed - the SIM will automatically connect to this operator.
