How can I resume sending a "reply" to the text messages I receive from family and friends
Although I'm able to make calls on my mobile phone, lately whenever I attempt to send a text to these exact phone number, I immediately receive a return message with the phone number I attempted to text returned, displayed and underlined; then states un-underlined "Error Invalid Number. Please re-send using a valid 10 digit mobile number or valid short code." And although this number changes on each occurrence it leaves a number i.e., "005400480041004E004B00200059004F00550020004D0073002E0".
ALSO, lately I've been getting notices texted to me stating names (some I don't know) saying they are "a new Facebook friend suggestion".
HOW CAN I STOP THIS INTRUSION!!
