I am trying to send a message to my phone using the SendMessage["SMS", "message"] function when a lengthy piece of code finishes running. My number is linked to my account and $MobilePhone returns the correct number, but I keep getting the error:
IntegratedServices`IntegratedServices::unexp: This service is currently not available. Please try again in a few minutes.
I've googled a bunch and can't seem to figure out what's wrong. Any ideas?
$ServiceCreditsAvailableto check how many service credits you have. – MarcoB Mar 08 '21 at 17:50
