SMS messages fail to send - error "Message Blocking active"
This problem began a few days ago. Before that, no problems. I cannot send or receive SMS messages to one specific contact. We can call each other and send MMS messages, but not SMS. If either of us tryto send SMS, we both receive the "Receiver <number> unable to receive message - Message Blocking is active." Neither of us has Message Blocking enabled for any numbers. We're both using Arduino phonesand use Google Messaging. We have: Deleted each other's contact and cleared the conversations: Shut off Wi-Fi: Reset the phones: Tried different SMS apps. Cleaned out the "Spam & Blocked" folders. Any other ideas besides going to visit T-Mobile?
