    Diagnostic Hardware Specs: iPhone 15 Pro | OS Version: iOS 18.1 | Archive Source: Apple Support Community #256344957

    I am running into a persistent issue on my iPhone 15 Pro running iOS 18.1.
    Whenever the machine encounters Carrier SM-DP+ server profile handshake timeout, the following diagnostic log appears in Console:

    CommCenter: [eSIM] Remote profile download timeout from SM-DP+ server for EID 890490321c3b

    I verified that hardware connections are intact and tested across different power sources. What is the verified diagnostic procedure to permanently eliminate this symptom?

    This canonical solution was verified and marked as solved in the Apple Support Community archive.

    Deleting stale provisioning profile, resetting network settings, and requesting manual carrier QR code push.

    Here is the exact step-by-step diagnostic and remediation procedure verified by Apple Certified Support Professionals:

    1. In Settings > Cellular, select the pending line and tap Delete eSIM.
    2. Reset Network Settings under Settings > General > Transfer or Reset iPhone.
    3. Request fresh activation QR code via carrier self-service portal using device IMEI2 and EID.

    Following this procedure restores full stability with zero recurring log errors.
