Hello, I have a A53 and inserted a second SIM. However it keeps on removing itself. I can use both SIMs but then one disappears. It can range from a couple of minutes to hours, but tends to be minutes. I can swap them around, the second SIM is always the one being missing/removed from the SIM list.
Is there anything I can do? The device is 2 months old, from Amazon.de.
Try cleaning the SIM contacts gently. You can also replace SIM, it is possible that the SIM is damaged. Last option is that the SIM drawer is corrupted - in that case you have to contact Samsung service.
