# Service campaign RRA12202405

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

A small number of Rolls\-Royce Phantom \(RRll/RR12\), Ghost \(RR21/RR22\), Spectre \(RR25\), and Cullinan \(RR31\) vehicles have been identified as having a potential software issue concerning the personal e\-SI M profile. As a result, vehicle telephone and Wireless Area Network \(WLAN\) hotspot functions via the personal e\-SIM may operate with a delay or not operate sporadically. The problem has been rectified with vehicle software version 24\-77\-540 \(RR21\-24\-11\-540 for RR21/RR22, RR25 and SlSA\-24\-11\-540 for RR11/RR12, RR31\), which is included in 1ST A version 4.50.4x.
