Galaxy Note20 Ultra SIM Card Keeps Disconnecting

For about a month, I’ve been experiencing frequent SIM card disconnections on my Samsung Galaxy Note20 Ultra. To identify the cause, I tried different SIM cards and even replaced my Vodafone SIM at the store, but the problem persists.

During this process, I contacted a Samsung service center, but they told me that since I purchased the device through Vodafone, I needed to reach out to them instead. My phone’s warranty has expired, and currently, I cannot establish a SIM connection at all — the issue occurs everywhere, regardless of location.

I am requesting free repair or technical support to resolve this issue and restore my device’s connectivity. My IMEI number is 351884130594056. I would appreciate your assistance with this matter.
