The plan has been working fine for over a month, except for some synchronization issues. However, we haven't been able to send text messages for the past two days. We can receive messages but cannot send them. When we tested it among ourselves, we realized that messages from our end are not going through. There are no error messages; the messages appear to be sent, so we thought everything was working fine. Please get back to me as we use this for business.
