I have a Galaxy A10e. My account is current. I can call out most days. However, at least every other week my phone will not let me call out, LIKE NOW. It says "server unreachable". It has happened in my home, at the store, etc, and this happened before COVID. Now, I'm just really annoyed. Also, at least once a week, my texts will show "fail to send" with an orange exclamation next to it. However, the people I am texting are receiving the texts unknown to me. If I restart my phone, the problem is usually solved, but not with the calling out problem. I sometimes have to wait until the next day before I can call out again. I cannot even call *611 because it says "server unreachable" right now. What is the problem?
