Hey @Efitz , Welcome to the 3Community 🙂
Firstly I would recommend checking if there are any updates on your phone that need to be installed, I would also recommend restarting your phone as this will help you to reestablish a fresh connection to the network. If this continues to happen I would recommend either calling 1913 or contacting our web messaging team here you can raise a ticket with the technical team to investigate further.
