I am not able to Sign up for Google SMS Channels, I am getting this error message:
What's wrong? What should I do?
This question appears to be off-topic. The users who voted to close gave this specific reason:
The SMS Channel was apparently stopped a while back as I was facing the same problem and a mail from the help desk of Google had content informing that since no progress is happening from Labs to a revenue generating effort into mainstream, they are discontinuing it.
So theres a chance that it might not be working for the same reason.
Or, maybe because you entered the wrong number :P
