I have Galaxy A54 5G. Over the last 24 hours, I am not able to make any phone calls as a message comes up saying “”Not registered on Network”. I am unable to access my online banking, as the 6 digit number for verification does not work.
I need 24 hour access to my phone as I am a diabetic with unstable blood sugars, and I need to be able to call my family if I have a Hypo.
