Unable to send SMS?

Yesterday I discovered that I am unable to send out any text messages. However, I am able to receive them. MMS seems to be working properly. My cycle started on Monday and SMS was working properly on Monday. No changes to my device and I went through the troubleshooting steps of https://fizz.ca/en/faq/i-cant-send-or-receive-text-messages.  There are several discussons on this forum that describe the same issue in the past.

I already contacted support and the standard, we will escalate this issue was done.   I am wondering if anyone else is experiencing this or for those that have experienced this in the past, what was done to fix it?
