Hello reynok, thank you for sharing your issue and explaining all the troubleshooting you have completed. Do you get any error messages when trying to send messages to either of those numbers? If you have any special characters, graphics, or a signature please make sure to turn those off and retest. Does this happen with every single message or intermittently? Since this has been going on for awhile, there may be a network issue affecting the text messages from going thru. If you ported from another carrier, it normally takes 72 hours for the inter-carrier text messaging to switch over. In this case, it seems like something changed for the worse. If this issue has not yet been resolved, please send me a direct message with your name and number, and the two numbers you are unable to text.
