Applies to: AIO-6 LTE models only
On the AIO-6 LTE status bar, the cellular signal tower icon may show a small blue dot at the bottom. This dot tells you which SIM type is in use:
- Signal tower with a small blue dot: You are using a locally purchased SIM (your own carrier’s SIM).
- Signal tower without the blue dot: You are using a CHIGEE-provided SIM.

This indicator does not change device features—it's just a quick way to see which SIM is active.
