SMS Not Working?


My SMS is no longer working where previously it was mostly OK. Two things happened:

  1. my Pixel 2 was updated to Android 10
  2. I updated to Webcore 21090822.

Any idea which one is causing no messages to come through now? And, what do I do about it?


If you are in the US, there is a daily limit on SMS messages. Maybe wait until tomorrow and try again?

If you are outside of the United States, SMS is currently not possible without using a third party app.
(You can thank SmartThings for that decision)


Did you opt in? Look for the thread in the ST forum.


Users with US phone numbers can text YES to 844-647 to opt in at any time after September 25, 2019 . Anyone who has opted in prior to that date will need to opt in once more.


I just opted-in, and just got a test message that I sent. I’ll see tomorrow if the rest of my daily messages and the problem reports now come thru as they did before.

But, when did this become necessary? And, were we notified about this and I missed it?

What is the daily limit? I’m in the US.


SmartThings pulled the plug on Sep 25, giving us only two days warning…

Currently, the daily limit for a US phone number is 100, as seen here.


Thanks. I did just search the ST forum, and found a bunch of messages about this. Seems that noone is happy with ST for making this change and for the manner they used to tell people.

So, is ST pushing us Webcore users to Hubitat? Maybe it’s time to seriously use that platform.


Yea, it was pretty crappy…

Reducing us to 100 SMS per day is somewhat understandable, but cutting off the rest of the world is just flat out wrong, IMO.

If I was being totally honest, I think in many ways, we may be to blame. Lately, I have seen an increase in ultra-spam pistons, that are really taxing on the infrastructure. (loops, power changes, every 5 seconds etc)

Limiting SMS will only help (at most) maybe 1% of the bandwidth. If spamming pistons are not re-written, or something does not change/grow on the SmartThings end, the next step they take may be more dramatic.

*shivers at the thought*


Just to make you aware, Hubitat removed native SMS from their services this summer.


I live in Puerto Rico and I have a US phone number and all my SMS stop working. i have try to opted-in and nothing.


Ouch!! That might be enough reason to change to another method of doing notifications.


Is there a best-practices doc somewhere that lists all these bad things, and ways to get around them? It seems that if SmartThings is going to take some drastic action based on these bad practices, they should tell you what they are so you can do something about them.


You may want to pay attention to this year’s SDC where ST may make some announcements…
