Blu Studio Max Phone..how do I only let texts come from contacts
I have had issues with text malware to my daughters phone. Her phone keeps getting texts from unknown number and disables my WiFi and continuous fake ads. I have done factory reset multiple times, changed memory card, changed sim card and the problem continues. My only option left is to only allow known contacts to text me. Can any one help me figure is out? or give me any advice?
Is this a good question?
