This issue just recently started for me last week. I am not getting texts or calls after a certain time of the day. In the morning I can get texts from individuals and group texts and then in the afternoon, I get nothing. Then the next morning, all the texts that were supposed to come to me finally show up. My parents tried calling me and it just rang and I never got the call. They even came over and called me while standing right by me and I never got the call. Texts are coming in 8 to 10 hours later. I have restarted my phone, removed the SIM card and placed it back in. Still an issue. Anyone else had this same issue? I am using an Samsung S9+ and it is two years told.
