Blocked from sending more text messages
Here's why: Yahoo Messenger limits the number of consecutive text messages you can send from your computer to a mobile number that isn't responding. This is designed to help prevent spam and other abuse.
Your contact's mobile device must be reset before they can receive additional text messages. The mobile owner should create new, separate text messages containing just the words:
- unblock all
- reset (sender's Yahoo ID)
Each of these messages can be sent to the wireless carrier's short code listed on the List of Supported Wireless Carriers by the receiving mobile owner.
