Why a device reboot can be helpful

Rebooting a device is often one of the quickest ways to resolve temporary connectivity issues. While it may seem simple, a reboot can reset several components involved in mobile connectivity and restore normal operation.

What happens when you reboot a device?

When a device is rebooted, it performs a clean restart of its operating system and modem. This can help by:

  • Resetting the cellular modem 
    The modem reinitialises its connection to the mobile network, which can clear temporary registration or signalling issues.
  • Re-establishing the network connection 
    The device disconnects from the network and performs a fresh network attach, which can help if it was previously connected to a network with degraded service or an incomplete session.
  • Refreshing SIM and network credentials 
    Rebooting can prompt the device to re-read SIM information and renegotiate network parameters with the mobile network.
  • Clearing temporary software or memory issues 
    Long-running devices may encounter transient software states or memory constraints that affect connectivity. A reboot clears these without requiring configuration changes.

When is a reboot especially helpful?

A device reboot can be effective if you are experiencing:

  • Intermittent or dropped connectivity
  • The device showing as offline unexpectedly
  • Failure to reconnect after a network change
  • Issues following configuration updates or SIM changes

What a reboot does not change

Rebooting a device does not:

  • Modify your SIM plan or account settings
  • Change network coverage in your location
  • Permanently fix hardware faults or antenna issues

If connectivity issues persist after rebooting, further investigation may be required.

Next steps

If the issue continues after a reboot, please contact our support team with details of the device, SIM, and the time the issue occurred. This will help us investigate further
