Sierra Airlink RV 50

Hello,
I am looking for help with troubleshooting my connection between ignition and a Sierra Airlink RV50.

I followed these steps to set up the RV50
https://support.inductiveautomation.com/index.php?/Knowledgebase/Article/View/123/0/sierra-wireless-airlink-rv50-setup-guide ,
and these steps to set up the ignition gateway
https://docs.inductiveautomation.com/display/DOC79/SMS+Notification+Profile.

When I test the SMS notification by going to the Pipeline/Notification Test Page and Submitting a Query I get warnings and errors in the logs and no text is never sent. The logger gives me these warning and error:

I am wondering if I could get any insight on what the warning and error message is saying and any possible solution.

Thanks

I have the same issue now. What was the solution?
Thanks,
Vadim
