Texting (SMS) problem since 5/15/25

The SMS messages I have formatted in my Rules are not being sent after 5/15/'25 approx. 10AM EST.
My phone is on the Verizon system. The phone is a Samsung S24.
The Sharptools is configured, usually via Windows 11 Home with all current updates.
System runs on SmartThings Hub(s).
SMS messages are sent by SharpTools Rules.
I’ve verified that the devices that the Rules monitor are functioning as intended.
However, after the time and date, noted, apparently the SMS never makes it out of the system.

My phone receives all other messages correctly. And other functions of the Hub seem to be proper.

Any insight and assistance would be appreciated.

If the Rule Logs show that the SMS was successfully sent, then it’s most likely filtering on the carrier side. The “success” of an SMS being sent means it was successfully handed off for delivery, but the carrier can still filter the message before they actually deliver it.

Carriers --like Verizon, T-Mobile, and AT&T-- can be real hit-or-miss when it comes to filtering SMS messages.

As a follow-up, I checked the SMS deliverability logs for the number attached to your account and it looks like your messages aren’t getting delivered as they have no message body.

If you are using dynamic content in the SMS body, I would double check that portion of your rule logic as I suspect it is not working as intended.
