Today I received #3 Text Message 'Notifications' on my phone.... Usually I recognize the sender from being on my contact list, and I usually see a partial message, but... The first text message notification was just an unknown phone number with an attachment, so I added it to my block list and deleted it... The second and third I just deleted cause I couldn't figure-out or remember how I added the other one to my block list- Question: I never opened any of them, should I be worried? A Virus, Malware perhaps? And are they really deleted or just marked for deletion or to be overwritten? All comments are welcome, thanks!
