Block operators on specific devices

emnify's mobile core network manages the network selection from the network side in conjunction with the SIM settings. It has a global view of the available radio networks, their supported features, and live network status. This view helps temporarily or permanently steer SIMs away from 'low signal quality' networks and to the networks with the strongest signal.

The manual carrier switching can be done in two ways:

  • Select the preferred operator in the device's menu.
  • Block other operators using the emnify Portal or emnify REST API.
info

Adding a network to the Blocked Operators list doesn't prevent your devices from trying to connect to those networks. You still see the attempts in the Events tab, but emnify's mobile core rejects any connection attempt. You should only use this feature to solve technical issues associated with specific operators.
