ICCID Unlock Check – Interposer SIM (RSIM, Turbo-SIM) Status

ICCID Unlock Check – Interposer SIM status check

Use the ICCID Unlock Check to verify whether an iPhone works with an interposer SIM solution (RSIM, Turbo‑SIM, Gevey, etc.) or is currently locked. This check is useful when the device is not factory unlocked and you plan to use a special SIM solution.

What is an interposer SIM?
An interposer SIM (e.g. RSIM, Turbo‑SIM, Gevey) is an add‑on that can allow a carrier‑locked iPhone to operate on another network.

What does the ICCID status mean?
Unlocked – the interposer SIM can be used
Locked – currently not usable or blocked

Example:
ICCID: 89014103270421600123
Status: Locked

This means the device is not currently compatible with the interposer SIM method, or the method is blocked.

When is this check useful?
When attempting to use RSIM / Turbo‑SIM or similar interposer solutions on a carrier‑locked iPhone.
