I am writing to report a critical issue with my Samsung Galaxy S24 that started immediately after installing the latest software update (November month software patch).
Problem Details:
The phone is no longer detecting my SIM card properly.
The SIM Manager settings do not open; it stays stuck on “Loading.”
The device frequently shows “No SIM card” or “SIM not detected,” even though the SIM is working in other phones.
This issue began only after the recent software update, and there was no problem before the update.

This is a follow-up regarding the SIM Manager and network issue I previously reported for my Samsung Galaxy S24.
After the initial complaint, the network started working briefly for a few hours, but the problem has returned. The phone again shows no network / no SIM detected, and the SIM Manager remains stuck on “Loading.” The issue is inconsistent and keeps coming back, which makes the device completely unreliable for normal use.
This is extremely disappointing, especially because the phone is recently purchased and the problem started immediately after the latest system update. As a customer, it is worrying that Samsung users now feel tension and fear whenever a new system update is released — due to issues like green lines, display problems, network failures, and now SIM Manager bugs.
I request the support team to treat this matter as urgent and provide a clear resolution. Please escalate this case and advise:
Whether Samsung is working on an update patch for this issue.
Whether a replacement device or service-center inspection is required.
Any immediate workaround until an official fix is released.
This situation is causing severe inconvenience and loss of trust in the device. I expect prompt action and a clear solution.
