These texts that let you know your plan has renewed are coming from Page Plus. Page Plus refers to them as SMS Notifications. So you can tell Page Plus to turn these off by sending them a message saying something like: “Please turn off my SMS Notifications so I won’t get renewal text messages in the middle of the night”.
Here is the address to use to send the message. Copy and Paste this into your browser’s address bar and click on and fill out the Support Ticket:
