I get those too. Worse yet, the ph. # for my cell phone had been used by someone in the past who obviously used his phone for not so nice purposes. I get messages to call or text a number for things like wanting to feel like a 17 yr old man again (??? I'm female and in my early 60's)!!! and worse things I won't mention. Yikes. I don't have a clue how to stop those from showing up in message section of my phone. Any suggestions?
