I’ve noticed that as of at least 6 days ago, people have not been receiving my text messages. However, I am able to receive text messages sent to me. I don’t remember when I updated to my current version of /e/OS. I’ve never had this problem before, other than very occasional SMS text messages I send that are not received. I’ve been trying to work out the problem with my mobile carrier today (Tello in the United States). The main thing we tried was doing a reset of “Wi-Fi,mobile Bluetooth”. The carrier agent also said that they would reset things on their end. However, these courses of action were not successful in fixing my problem.
