Hello, I have an unlocked galaxy Note 20u and I have been getting this error saying sim card not active randomly appearing and needing a phone restart to reactivate it. This started occuring after upgrading my Verizon plan to a unlimited 5g ultra wideband plan. Does anyone have any suggestions on how to fix this issue?
Thanks in advance
I have Samsung note 20 ultra and I don't have problems with my phone. Did you try to remove Sim card from holder and insert again, maybe that could be solving problems with your Sim card,
Make sure Sim card is clean and free of cracks and scratches. What I would recommend if it is a possibility is that your try using that Sim card in a different phone to see if it is faulty/defective. Do you swap Sim cards a lot?
