I'd continue to suggest using Pushover.
You visit pushover.net to get an account and that gives you a user 'token' (long long random letters and numbers) and add in the devices that will receive the notification.. phone/tablet, etc. Then you create an application and it responds with an app 'token' (the 2nd long long random letters and numbers.)
Back on Hubitat: Devices: Add Virtual Device
Device Name: Pushover
Device Network ID: psh01 <-- example: (can be anything UNIQUE)
Type: Pushover Driver
Click Save Device
In Preferences for the device you just created:
Paste the Tokens in their respective fields.. user token in User Key; app token in Application Key
Click Save Preferences.
That's it, you're done creating -- time to start using your new Pushover notification system. Simply swap to using the Pushover device in the Rules where you are using SMS.
Pushover is FREE for the first week. If you like it, and I'm predicting you will.. you pay a once only $4.99 to get 7500 notifications per month.
