Who called from 9315705535

Received a text from this number and it is one I do not recognize.

I also received a text from tgus number yesterday and they said Hi April....I do not know anyone in this area and no follow-up text either.

I too got a text from this number and it said, "Hiii Sierra", but I got a follow up text that said, "oh no I have no reception :(" I have asked 4 times now who it is and they haven't texted back since! So, idk what to do!

Ignore the messages.  The sender is either a telemarketer or a scammer.  

By calling or texting them you have told them that the number is in use by someone who answers random texts.  You will get more scam and sales texts.  Delete them all.
