Use Cases/Information
The following lists contain information about the capabilities of dual-SIM modems used in Cradlepoint endpoints.
Use Case
The recommended use case for dual-SIM modems is to help in managing your data-plan caps. If one SIM in a dual-SIM modem reaches its data-plan cap, the endpoint fails over to the second SIM.
Cradlepoint modems that support dual-SIM cards have the following characteristics.
- These modems contain one radio with the ability to communicate with its two SIM cards.
- Each SIM card is treated as a separate device by the modem. This allows only one SIM card to connect at the same time.
- Each SIM can have its own configuration attached to the slot it’s installed.
- When failing over to the secondary SIM, the modem reconfigures it’s APN settings. Due to the time required for APN reconfiguration, it’s a much faster to fail over to a second modem vs. a second SIM.
- If only using one SIM, we recommend using the first slot because it’s powered on first.
