Second SIM card disconnects randomly

Observer

Hi,

I've recently started using a second SIM card on my Galaxy Note 9, which I use for 4g internet. However, the card randomly disconnects, the phone stops detecting it. If I restart my phone, it can see it just fine. There isn't even wiggle room to place it differently on the card holder, there's no warning or error message, it just disappears until the next reboot. Anyone else experiencing this or has any idea how I could fix it?

No my Note 9 hasn't had this issue.

 

As a process of elimination can you try your sim card in another phone and then see what happens.

 

A Samsung Experience Store or Samsung Service Centre can run a diagnostic test on the phone.
