Question

  • When does the Network List update take effect?

  • How long does it take for the device to recognize the Network List has changed?

Answer

The Network List change takes effect when the device requests permission to attach to (register with) a network.

Cause

Upon the registration attempt, Onomondo receives an updateLocation request sent local RAN (providing us with information about the device's current status on the local network).

  • If the network is present on the network list assigned to the SIM - Onomondo responds with "insertSubscriberData" and the registration is successful.

  • If the network is not present on the network list assigned to the SIM, Onomondo returns "operatorDeterminedBarring" and the network registration attempt is rejected.

If the device is already connected to a network and has an ongoing data session, it will remain on that network until the device requests permission to join (attach to) the network again. The Network List update does not instruct the device to disconnect from the current network. From the modem POV, it will continue to use the current network unless told otherwise.
