Who called from 3475099073

Spam text message enquiry about an online ad I placed on gumtree.com.au.
Email address attached was [email protected]

Hey I got an sms from this guy too and he is asking for payment details and such and more photos of the item...did he say he was in malaysia?

I got that message at 1am this morning!!

I also received the following message:
"Whats the firm price for your gumtree advert and present condition email me on [email protected] because my battery is dead so we can talk better.¤Sent from my iPhone"

I received a similar message from a similar number a couple of days ago that a web search also suggested was spam.

I didn't reply to either message, so not sure what the scam is.
