Hi ​@afitzgerald1 

We have looked into it and there was an outgoing text which trigger the charge while the phone was connected to a tower outside of Canada and the US, we recommend checking the PDF bill and the usage section in self serve for more details.

If you need more details, please let us know and we can send you a PM.
