Randomly today i got a text message from someone with no name. The sender just has a 1 as its name. My android can't go online unless i turn on my moblie data so i couldn't see what the sender has send as it requires me to download 32KB from his text. What are the risk that could happen if i decided to turn on my moblie data and download this text message? Any chance of it being a hack, keylogger or something similar? Thanks in advance and does anyone else have this problem in the past as well?
